Effect of transcutaneous spinal direct current stimulation on spasticity in upper motor neuron conditions: a systematic review and meta-analysis.

STUDY DESIGN: A systematic review and meta-analysis of clinical trials. OBJECTIVES: To determine the effect of non-invasive transcutaneous spinal direct current stimulation (tsDCS) on spasticity, activity limitations and participation restrictions in various upper motor neuron diseases. METHODS: Six databases including CINAHL plus, Cochrane CENTRAL, Embase, MEDLINE, SCOPUS and Web of Science were searched for the relevant records from January 2008 to December 2022. Two reviewers independently selected and extracted data on spasticity, activity limitations and participation restrictions. The risk of bias was evaluated using the PEDro scale while the GRADE approach established the certainty of the evidence. RESULTS: Eleven studies were identified of which 5 (45.5%) were rated as having a low risk of bias and 8 (72.7%) were meta-analyzed. The meta-analyses did not show any significant differences between cathodal (SMD = -0.67, 95% CI = -1.50 to 0.15, P = 0.11, I2 = 75%, 6 RCTs) or anodal (SMD = 0.11, 95% CI = -0.43 to -0.64, p = 0.69, I2 = 0%, 2 RCTs) and sham tsDCS for spasticity. There was also no significant difference between active and sham tsDCS for activity limitations (SMD = -0.42, 95% CI = -0.04 to 0.21, p = 0.2, I2 = 0%, 2 RCTs) and participation restrictions (MD = -8.10, 95% CI = -18.02 to 1.82, p = 0.11, 1 RCT). CONCLUSIONS: The meta-analysis of the available evidence provides an uncertain estimate of the effect of cathodal tsDCS on spasticity, activity limitation and participation restriction. It might be very helpful, or it may make no difference at all. However, considering the level of the evidence and the limitation in the quality of the majority of the included studies, further well-designed research may likely change the estimate of effect.

The feasibility, safety, physiological and clinical effects of high-intensity interval training for people with Parkinson's: a systematic review and meta-analysis.

BACKGROUND: Exercise is important for people with Parkinson's (PwP), with high-intensity interval training (HIIT) proposed as a feasible and effective exercise modality. However, no literature synthesis for PwP has been undertaken. OBJECTIVES: To evaluate the feasibility, safety, physiological and clinical effects of HIIT for PwP. METHODS: Systematic searches of Medline, Embase, CINAHL, Web of Science, and Google Scholar were undertaken. Studies that included ≥ 2 weeks of HIIT for PwP and reported sufficient detail for full quality assessment were eligible. Quality was assessed with the TESTEX scale or the Downs and Black tool according to study design. Feasibility and safety data, physiological and clinical outcomes were extracted. Meta-analyses explored the pooled effects of HIIT on VO2peak/max compared to moderate-intensity continuous exercise (MICE) and usual care. RESULTS: Eleven articles were identified (seven controlled/comparator studies and four single group) including 117 HIIT participants predominantly of mild-to-moderate disease severity. HIIT programmes were professionally supervised and between 6 weeks and 24 months. Overall, study quality was deemed to be moderate to good. Following screening, nine studies reported 90-100% programme completion; however, only one was > 12 weeks in duration. Adverse events were uncommon. HIIT improved VO2peak/max compared to usual care, but not to MICE. Increased brain-derived neurotrophic factor (BDNF) and improved motor symptoms were also reported. CONCLUSION: Up to 12 weeks of supervised HIIT appears to be feasible and safe for some people with mild-to-moderate disease severity. HIIT improves cardiorespiratory fitness and may increase BDNF and improve motor symptoms in PwP. Future studies should explore safe ways to facilitate access and long-term adherence.

Relationship Between Physiological and Perceived Fall Risk in People With Multiple Sclerosis: Implications for Assessment and Management.

OBJECTIVE: This study evaluated the relationship between physiological and perceived fall risk in people with multiple sclerosis (MS). DESIGN: Secondary analysis of data from prospective cohort studies undertaken in Australia, the United Kingdom, and the United States. SETTING: Community. PARTICIPANTS: Ambulatory people with MS (N=416) (age 51.5±12.0 years; 73% female; 62% relapsing-remitting MS; 13.7±9.9 years disease duration). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: All participants completed measures of physiological (Physiological Profile Assessment [PPA]) and perceived (Falls Efficacy Scale-international [FESi]) fall risk and prospectively recorded falls for 3 months. RESULTS: 155 (37%) of the participants were recurrent fallers (≥2 falls). Mean PPA and FESi scores were high (PPA 2.14±1.87, FESi 34.27±11.18). The PPA and the FESi independently predicted faller classification in logistic regression, which indicated that the odds of being classified as a recurrent faller significantly increased with increasing scores (PPA odds ratio [OR] 1.30 [95% CI 1.17-1.46], FESi OR 1.05 [95% CI 1.03-1.07]). Classification and regression tree analysis divided the sample into four groups based on cutoff values for the PPA: (1) low physiological/low perceived risk (PPA <2.83, FESi <27.5), (2) low physiological/high perceived risk (PPA <2.83, FESi >27.5), (3) high physiological/low perceived risk (PPA >2.83, FESi <35.5), and (4) high physiological/high perceived risk (PPA <2.83, FESi >35.5). Over 50% of participants had a disparity between perceived and physiological fall risk; most were in group 2. It is possible that physiological risk factors not detected by the PPA may also be influential. CONCLUSIONS: This study highlights the importance of considering both physiological and perceived fall risk in MS and the need for further research to explore the complex interrelationships of perceptual and physiological risk factors in this population. This study also supports the importance of developing behavioral and physical interventions that can be tailored to the individual's needs.

A whole-genome, radiation hybrid mapping resource of hexaploid wheat.

Generating a contiguous, ordered reference sequence of a complex genome such as hexaploid wheat (2n = 6x = 42; approximately 17 GB) is a challenging task due to its large, highly repetitive, and allopolyploid genome. In wheat, ordering of whole-genome or hierarchical shotgun sequencing contigs is primarily based on recombination and comparative genomics-based approaches. However, comparative genomics approaches are limited to syntenic inference and recombination is suppressed within the pericentromeric regions of wheat chromosomes, thus, precise ordering of physical maps and sequenced contigs across the whole-genome using these approaches is nearly impossible. We developed a whole-genome radiation hybrid (WGRH) resource and tested it by genotyping a set of 115 randomly selected lines on a high-density single nucleotide polymorphism (SNP) array. At the whole-genome level, 26 299 SNP markers were mapped on the RH panel and provided an average mapping resolution of approximately 248 Kb/cR1500 with a total map length of 6866 cR1500 . The 7296 unique mapping bins provided a five- to eight-fold higher resolution than genetic maps used in similar studies. Most strikingly, the RH map had uniform bin resolution across the entire chromosome(s), including pericentromeric regions. Our research provides a valuable and low-cost resource for anchoring and ordering sequenced BAC and next generation sequencing (NGS) contigs. The WGRH developed for reference wheat line Chinese Spring (CS-WGRH), will be useful for anchoring and ordering sequenced BAC and NGS based contigs for assembling a high-quality, reference sequence of hexaploid wheat. Additionally, this study provides an excellent model for developing similar resources for other polyploid species.

Systematic Review: The Effectiveness of Interventions to Reduce Falls and Improve Balance in Adults With Multiple Sclerosis.

OBJECTIVES: To evaluate the effectiveness of interventions in reducing falls and/or improving balance as a falls risk in multiple sclerosis (MS). DATA SOURCES: Computer-based and manual searches included the following medical subject heading keywords: "Multiple Sclerosis AND accidental falls" OR "Multiple Sclerosis AND postural balance" OR "Multiple Sclerosis AND exercise" OR "Multiple Sclerosis AND physical/physio therapy" NOT animals. All literature published to November 2014 with available full-text details were included. STUDY SELECTION: Studies were reviewed against the PICO (participants, interventions, comparisons, outcomes) selection criteria: P, adults with MS; I, falls management/balance rehabilitation interventions; C, randomized/quasi-randomized studies comparing intervention with usual care or placebo control; O, falls outcomes and measures of balance. Fifteen articles of the original 529 search results were included. DATA EXTRACTION: Two reviewers independently extracted data and assessed methodological quality using the Cochrane Risk of Bias tool. DATA SYNTHESIS: Random-effects meta-analysis indicated a small decrease in falls risk (risk ratio, .74), although the 95% confidence interval (CI) crossed 1 (95% CI, .12-4.38). The pooled standardized mean difference (SMD) for balance outcomes was .55 (95% CI, .35-.74). SMD varied significantly between exercise subgroupings; gait, balance, and functional training interventions yielded the greatest pooled effect size (ES) (SMD=.82; 95% CI, 0.55-1.10). There was a moderate positive correlation between program volume (min/wk) and ES (Cohen's d) (r=.70, P=.009), and a moderate negative correlation between program duration in weeks and ES (r=-.62, P=.03). Variations in interventions and outcomes and methodological limitations mean that results must be viewed with caution. CONCLUSIONS: This review suggests that balance may improve through exercise interventions, but that the magnitude of the improvements achieved in existing programs may not be sufficient to impact falls outcomes. Supporting participants to achieve an appropriate intensity of practice of highly challenging balance activities appears to be critical to maximizing effectiveness.

Frequency, characteristics, and consequences of falls in multiple sclerosis: findings from a cohort study.

OBJECTIVE: To evaluate falls rate and the characteristics of falls (including fall-related injuries) in a multiple sclerosis (MS) cohort. DESIGN: As part of a study evaluating falls risk, a cohort of 150 participants prospectively recorded actual and near fall events using a daily diary over 3 months, as well as the circumstances of each fall including related injuries. SETTING: Community setting. PARTICIPANTS: A population-based sample of people (N=150) with a confirmed diagnosis of MS (Expanded Disability Status Scale, 3.5-6.5) was recruited via a patient-centered longitudinal study database of disease course in people with MS. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Rate of actual and near falls, circumstances and consequences of falls (including rates and type of injury plus follow-up care). RESULTS: The response rate for the falls diary was 92.7%. A total of 672 actual falls and 3785 near falls were recorded, with a moderate correlation between the numbers of actual and near falls per person (ρ=.474; 95% confidence interval, .34-.59). Men recorded significantly more falls than women. Falls were associated with a range of activities, although 27.6% occurred during general mobility activities such as walking, turning, and moving between positions. Injuries occurred in 11.1% of falls, with 6 individuals requiring medical attention. CONCLUSIONS: People with MS experience high numbers of falls, with associated injuries. Falls occur during a wide range of activities, reflecting their potential impact on daily life. Evaluating the characteristics of individuals who experience frequent near falls but few actual falls may be valuable for research and clinical practice.

The Experience of Physical Recovery and Physical Rehabilitation Following Hospital Discharge for Intensive Care Survivors-A Qualitative Systematic Review.

BACKGROUND: Over 120,000 people in the UK survive critical illness each year, with over 60% of these experiencing mobility issues and reduced health-related quality of life after discharge home. This qualitative systematic review aimed to explore critical care survivors' perceptions, opinions, and experiences of physical recovery and physical rehabilitation following hospital discharge. METHODS: This review followed the Joanna Briggs Institute (JBI) methodology with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and was conducted between January 2020 and June 2022. The search was conducted using the following databases: Embase, CINAHL, Medline Ovid, Cochrane, and the Joanna Briggs Institute, and sources of grey literature were searched for eligible studies. Qualitative studies focused on physical rehabilitation or recovery, involving adult survivors of critical illness who had been discharged from hospital. RESULTS: A total of 7 of 548 identified studies published in 2007-2019 were eligible for inclusion. The findings indicate that qualitative evidence around the experiences of physical recovery and rehabilitation interventions following discharge home after critical illness is limited. Three synthesised findings were identified: 'Positivity, motivation and hope'; 'Recovery is hard and patients need support'; and 'Patients experience challenges in momentum of physical recovery'. CONCLUSIONS: Survivors struggle to access healthcare professionals and services following discharge home, which influences the momentum of physical recovery. Supervised exercise programmes had a positive impact on the perception of recovery and motivation. However, 'simple' structured exercise provision will not address the range of challenges experienced by ICU survivors. Whilst some factors influencing physical recovery are similar to other groups, there are unique issues experienced by those returning home after critical illness. Further research is needed to identify the support or interventions survivors feel would meet their needs and assist their physical recovery. This study was prospectively registered with Prospero on 3/2/2020 with registration number CRD42020165290.

Home-based high-intensity interval training for people with Parkinson's: Protocol for the HIIT-Home4Parkinson's randomized, controlled feasibility study.

Background: High-intensity interval training (HIIT) is feasible and beneficial for some people with Parkinson's (PwP), although adherence to extended programs may be problematic. PwP face barriers to exercise such as lack of time, expense, and difficulty with travel logistics due to motor symptoms. HIIT based in the home setting if practical, could therefore be apposite for PwP by overcoming these barriers. However, until now, no home-based HIIT program for PwP has been developed. Cocreated by PwP, clinicians, and family members, the HIIT-Home4Parkinson's (HH4P) program is an innovative, 12-week home-based HIIT program for PwP. This protocol describes a feasibility study designed to assess the feasibility and safety of the HH4P program, explore outcomes that may be sensitive to change, and inform the implementation of a potential full trial. Methods/design: Using a randomized controlled parallel group design, 24 independently mobile people with Parkinson's of mild to moderate disease severity will be randomized 1:1 to either the HH4P program plus usual care, or usual care alone. Both groups will be assessed at baseline, and upon the completion of the program. Outcomes will include feasibility and safety factors such as recruitment, completion, adverse events, and intervention fidelity with qualitative evaluation along with mechanistic, physiological, and clinical outcomes. Discussion: Results of this study will inform the rationale and methodological considerations for a full trial with long-term follow-up. Ultimately, further establishing the practicality and utility of home-based HIIT could provide an important exercise option for PwP, potentially leading to extended participation and increased health and well-being for this population.

Risk factors for falls in multiple sclerosis: an observational study.

BACKGROUND: People with multiple sclerosis (MS) experience frequent falls, which are associated with impairments and limitations to activities and participations. OBJECTIVE: The objective of this paper is to evaluate falls risk factors using robust clinical measures. METHODS: A total of 150 individuals (confirmed MS diagnosis, Expanded Disability Status Scale (EDSS) 3.5-6.5) were recruited, with 148 participants included in the final analysis. Demographic data were collected and performance assessed in eight predictor measures (Physiological Profile Assessment (PPA), Brief Ataxia Rating scale, Ashworth scale (Ashworth), Modified Falls Efficacy scale, Symbol Digit Modalities Test, dual-task interference, lying/standing blood pressure, static/dynamic visual acuity). Participants prospectively recorded falls over three months using a daily diary. People were classified as "fallers" based on reports of ≥ two falls. RESULTS: A total of 104 participants recorded 672 falls; 78 (52.7%) reported ≥ two falls. Continence issues, previous falls history and use of prescribed medications were each associated with increased risk of being a "faller". Ashworth and PPA risk score contributed significantly to a logistic regression model predicting faller/non-faller classification. The reduced model (Ashworth, PPA, EDSS) showed fair-to-good predictive ability (ROC c-statistic 0.73, sensitivity 70%, specificity 69%). CONCLUSION: This study confirms the high prevalence of falls in ambulant people with MS. Important potentially modifiable risk factors are identified, suggesting aspects to target in falls interventions.

Co-Creating a Feasible, Acceptable and Safe Home-Based High-Intensity Interval Training Programme for People with Parkinson's: The HIIT-Home4Parkinson's Study.

High-intensity interval training (HIIT) is useful and feasible for some people with Parkinson's (PwP), although long-term adherence may be problematic. If practical, undertaking HIIT in the home setting could be a way to encourage continued participation. However, no home-based HIIT programme has been developed for this population. Therefore, the objectives of this study were to co-create a feasible, accessible, and safe home-based HIIT programme for PwP, including intervention components and logic model. This supports the longer term aim to assess the practicality and utility of home-based HIIT for PwP. The study included three stages. Firstly, an initial HIIT programme and logic model proposal was developed based on existing evidence. This was refined through an iterative, co-creative process of focus groups, exercise testing and interviews involving end-users and relevant stakeholders. Finally, a draft intervention was produced with further co-creator input. During the iterative process, five focus groups, 10 exercise testing sessions and 10 post exercise interviews were undertaken, involving academic researchers, 6 PwP, one family member and two clinicians. These co-creators developed HIIT-Home4Parkinson's (HH4P), a 12-week thrice weekly home-based HIIT programme for PwP based on adaptability, individualisation, and remote support. Despite methodological limitations within the development process, the co-created HH4P programme could be feasible, safe, and useful for PwP. A feasibility study should now be undertaken to address remaining uncertainties prior to a full trial.

Telerehabilitation for people with physical disabilities and movement impairment: development and evaluation of an online toolkit for practitioners and patients.

PURPOSE: Telerehabilitation has increasingly been used since the COVID-19 pandemic but with limited guidance available on undertaking physical assessments using remote methods. We aimed to provide such guidance by developing a Telerehab Toolkit, an online information and training resource for practitioners, patients, and carers on telerehabilitation for people with physical disabilities and movement impairment. MATERIALS AND METHODS: Development and evaluation of the toolkit were informed by the Knowledge to Action framework and took place iteratively in two phases-knowledge creation and action. Information was collated from various sources including literature review, online survey, service evaluation, and focus group discussions. The toolkit has been evaluated using think-aloud interviews, e-mail and social media feedback from users, and analytics data on user engagement with the website. RESULTS: The Telerehab Toolkit focuses on remote physical assessments, and contains information on technology, digital skills, remote assessment tools, information governance, and safety for telerehabilitation. Resources include top tips from practitioners and patients, how-to guides, checklists, videos, and links to evidence. CONCLUSIONS: The Telerehab Toolkit has been well-received by practitioners, healthcare students, patients, and carers, is being disseminated widely, and is freely available (www.plymouth.ac.uk/research/telerehab). IMPLICATIONS FOR REHABILITATIONTelerehabilitation has been increasingly used since the COVID-19 pandemic, but with limited guidance and training for practitioners on undertaking safe and effective remote physical assessments.The Telerehab Toolkit has been developed iteratively using the Knowledge to Action framework; it is a free online resource for practitioners and patients with specific guidance on telerehabilitation for physical disabilities and movement impairment.It is anticipated that the resource will help to improve the knowledge, skills, and confidence of the current and future rehabilitation workforce.

Telerehabilitation for People With Physical Disabilities and Movement Impairment: A Survey of United Kingdom Practitioners.

BACKGROUND: Telerehabilitation is a feasible and potentially effective alternative to face-to-face rehabilitation. However, specific guidance, training, and support for practitioners who undertake remote assessments in people with physical disabilities and movement impairment are limited. OBJECTIVE: The aims of this survey of United Kingdom-based health and social care practitioners were to explore experiences, assess training needs, and collate ideas on best practices in telerehabilitation for physical disabilities and movement impairment. The aim will be to use the findings to inform a practical tool kit and training package for telerehabilitation use. METHODS: UK rehabilitation practitioners were invited to complete an online questionnaire from November to December 2020. Opportunity and snowball sampling were used to recruit participants from professional and educational networks, special interest groups, and via social media. Closed questionnaire items were analyzed using descriptive statistics. Qualitative inductive analysis using NVivo was used for open responses. RESULTS: There were 247 respondents, of which 177 (72%) were physiotherapists and occupational therapists. Most (n=207, 84%) had used video-based consultations (typically supported by telephone and email), and the use of this method had increased in frequency since the COVID-19 pandemic. Practitioners perceived telerehabilitation positively overall and recognized benefits for patients including a reduced infection risk, convenience and flexibility, and reduced travel and fatigue. Common obstacles were technology related (eg, internet connection), practical (eg, difficulty positioning the camera), patient related (eg, health status), practitioner related (eg, lack of technical skills), and organizational (eg, lack of access to technology). Support from family members or carers was a major facilitator for successful remote consultations. Of the 207 respondents who had used video-based consultations, 103 (50%) had assessed physical impairments using this method, 107 (52%) had assessed physical function, and 121 (59%) had used patient-reported outcome measures. Although practitioners generally felt confident in delivering video-based consultations, they felt less proficient in undertaking remote physical assessments, expressing concerns about validity, reliability, and safety. Only 46 of the 247 (19%) respondents had received any training in telerehabilitation or video consultations, and some felt they were "feeling their way in the dark." Practitioners desired training and guidance on physical assessment tools suitable for remote use, when to use video-based consultations or alternative methods, governance issues, digital platforms, and signposting to digital skills training for themselves and their patients. CONCLUSIONS: In response to the COVID-19 pandemic, practitioners rapidly adopted telerehabilitation for people with physical disabilities and movement impairment. However, there are technical, practical, and organizational obstacles to overcome, and a clear need for improved guidance and training in remote physical assessments. The findings of this survey will inform the development of a tool kit of resources and a training package for the current and future workforce in telerehabilitation.

Telerehabilitation for physical disabilities and movement impairment: A service evaluation in South West England.

RATIONALE, AIMS AND OBJECTIVES: Telerehabilitation was used to ensure continued provision of care during the COVID-19 pandemic, but there was a lack of guidance on how to use it safely and effectively for people with physical disabilities and movement impairment. In this service evaluation, we aimed to collate information on practitioner and patient experiences, challenges and facilitators, and examples of best practice to inform the development of an online toolkit and training package. METHODS: Guided discussions were carried out with 44 practitioners, 7 patients and 2 carers from five health and social care organisations in South West England, and analysed thematically. RESULTS: Practitioners and patients had positive experiences of telerehabilitation and were optimistic about its future use. Recognized benefits for people with physical disabilities included greater flexibility, reduced travel and fatigue, having appointments in a familiar environment and ease of involving family members. Challenges encountered were: technological (usability issues, access to technology and digital skills); difficulties seeing or hearing patients; the lack of 'hands-on' care; and safety concerns. Facilitators were supported by colleagues or digital champions, and family members or carers who could assist patients during their appointments. Key themes in best practice were: person-centred and tailored care; clear and open communication and observation and preparation and planning. Practitioners shared tips for remote physical assessments; for example, making use of patient-reported outcomes, and asking patients to wear bright and contrasting coloured clothing to make it easier to see movement. CONCLUSION: Telerehabilitation holds promise in health and social care, but it is necessary to share good practice to ensure it is safe, effective and accessible. We collated information and recommendations that informed the content of the Telerehab Toolkit (https://www.plymouth.ac.uk/research/telerehab), a practical resource for practitioners, patients and carers, with a focus on remote assessment and management of physical disabilities and movement impairment.

Technologies to Support Assessment of Movement During Video Consultations: Exploratory Study.

BACKGROUND: Understanding and assessing patients' body movements is essential for physical rehabilitation but is challenging in video consultations, as clinicians are frequently unable to see the whole patient or observe the patient as they perform specific movements. OBJECTIVE: The objective of this exploratory study was to assess the use of readily available technologies that would enable remote assessment of patient movement as part of a video consultation. METHODS: We reviewed the literature and available technologies and chose four technologies (Kubi and Pivo desktop robots, Facebook Portal TV, wide-angle webcam), in addition to help from a friend or a simple mobile phone holder, to assist video consultations. We used 5 standard assessments (sit-to-stand, timed "Up & Go," Berg Balance Test, ankle range of motion, shoulder range of motion) as the "challenge" for the technology. We developed an evaluation framework of 6 items: efficacy, cost, delivery, patient setup, clinician training and guidance, and safety. The coauthors, including 10 physiotherapists, then took the roles of clinician and patient to explore 7 combinations of 5 technologies. Subsequently, we applied our findings to hypothetical patients based on the researchers' family members and clinical experience. RESULTS: Kubi, which allowed the clinician to remotely control the patient's device, was useful for repositioning the tablet camera to gain a better view of the patient's body parts but not for tracking movement. Facebook Portal TV was useful, but only for upper body movement, as it functions based on face tracking. Both Pivo, with automated full body tracking using a mobile phone, and the wide-angle webcam for a laptop or desktop computer show promise. Simple solutions such as having a friend operate a mobile phone and use of a mobile phone holder also have potential. The setup of these technologies will require better instructions than are currently available from suppliers, and successful use will depend on the technology readiness of patients and, to some degree, of clinicians. CONCLUSIONS: Technologies that may enable clinicians to assess movement remotely as part of video consultations depend on the interplay of technology readiness, the patient's clinical conditions, and social support. The most promising off-the-shelf approaches seem to be use of wide-angle webcams, Pivo, help from a friend, or a simple mobile phone holder. Collaborative work between patients and clinicians is needed to develop and trial technological solutions to support video consultations assessing movement.

Scope, context and quality of telerehabilitation guidelines for physical disabilities: a scoping review.

OBJECTIVE: To identify the available guidance and training to implement telerehabilitation movement assessments for people (adults and children) with a physical disability, including those recovering from COVID-19. DESIGN: Rapid scoping review. INCLUDED SOURCES AND ARTICLES: PubMed, CINAHL, PsychInfo, Cochrane, Embase, Web of Science, PEDro, UK Health Forum, WHO, National Archives and NHS England were searched using the participant-concept-context framework from 2015 to August 2020. Primary studies that recruited individuals with physical disabilities and guidance documents aimed at providers to implement movement-related telerehabilitation were included. RESULTS: 23 articles (11 primary research studies, 3 systematic reviews and 9 guidance documents) were included out of 7857 that were identified from the literature search. Two main issues were found: (1) telerehabilitation guidance (from both research studies and guidance documents) was not specific to movement-related assessment and (2) most primary research studies provided neither guidance nor training of movement-specific assessment to practitioners. Of the COVID-19 related guidance, two articles reported COVID-19 management that only referred to identifying COVID-19 status without references to specific movement-related guidance. CONCLUSIONS: Telerehabilitation guidance and training have existed pre-COVID-19, yet the lack of specific movement-related information and provider support is surprising. This gap must be addressed to optimise effective implementation of remote assessments for those with physical disabilities. REVIEW REGISTRATION: Open Science Framework: osf.io/vm6sp.

What are the perceptions and experiences of falls amongst people with stroke who live in the community?

Purpose: To explore the perceptions and experiences of people with stroke living in the community with regard to the perceived causes, impact and solutions to minimise falls.Methods: A qualitative research approach underpinned by a constructivist paradigm utilising a phenomenological methodology. Twelve people with stroke participated in focus groups; the data were analysed using thematic analysis.Results: Three themes and one foundation theme were identified. (1) Trips and triggers: falls were perceived to be linked to external triggers, one of which was walking aids. (2) Blame and burden: self-blame and worry about being a burden may be associated with underreporting of falls. (3) Restrict and reduce: people with stroke restrict activity and reduce participation to manage falls. The underpinning theme of self-efficacy highlights the apparent diminished falls self-efficacy, and the perception amongst the participants that falls are inevitable.Conclusions: This study highlights the perceived negative consequences of falls amongst people with stroke, and the potential contribution of falls to the reduced levels of physical activity often seen following a stroke. Our findings emphasise the need to address falls and balance related self-efficacy alongside strategies to promote safe mobility. A paradigm shift may be needed to highlight potentially modifiable intrinsic risk factors and emphasise the relevance and value of proactive fall prevention to people with stroke.Implications for rehabilitationPeople with stroke may not report falls or may minimise their significance, using alternative terms such as trips and stumbles. Rehabilitation staff need to approach falls in a way that emphasises the positive value of reporting and addressing falls management proactively.People with stroke may focus on extrinsic rather than intrinsic factors, so it is important to identify and highlight potentially modifiable intrinsic falls risks during assessment and treatment.Falls are associated with the use of mobility aids, and people frequently report using multiple aids obtained from a range of sources. Our study findings suggest that assessment and education about the appropriate use of mobility aids should be integral to stroke-specific falls interventions.Falls are often associated with activity reduction and avoidance, which could contribute to reduced participation and increased secondary issues. Approaches to encourage physical activity after stroke need to include recognition of falls risk and methods to optimise safe mobility.The relationship between self-efficacy and people's attitudes and responses to falling is an important consideration. It is likely that that self-efficacy strategies could positively contribute to the effectiveness of stroke falls management interventions.

"A non-person to the rest of the world": experiences of social isolation amongst severely impaired people with multiple sclerosis.

Purpose: To gain insight into the experiences of, and potential solutions to, social isolation amongst severely impaired people with multiple sclerosis.Methods: A phenomenological research approach using face-to-face, in-depth semi-structured, audio-recorded interviews. Data were transcribed and analyzed thematically.Results: Sixteen severely impaired people with multiple sclerosis were interviewed (Expanded Disability Status Scale >6.5); aged 38-72 years, nine female, time since diagnosis ranged 3-30 years). Four key themes were generated in line with the study objectives, each with further sub-themes. The themes were (1) Definitions of isolation (2) Causes of isolation (3) Impact of isolation, and (4) Potential eases of isolation.Conclusions: Data portrayed social isolation as complex and multi-factorial in its definitions, its causes, and its impact. Isolation is not just about being lonely or left on one's own, but represents a spiral of impacts. Physical deterioration can lead to reduced choice and control regarding access to, and interaction with others and society, affecting personal identity. Sometimes this leads to further self-isolation. Personalised psychosocial support, with improved ease of access, focused on helping people with severe multiple sclerosis regain a sense of self and their place in the world may ease social isolation.Implications for rehabilitationPeople with severe multiple sclerosis can experience a sense of powerlessness, a lack of choice and control over daily life, leading to changes in self-identity and social isolation.Peoples' experiences are very personal, and any approach to help deal with social isolation needs to be based in considering how to think positively about how life can be lived and how to make that work.Multiple sclerosis support groups should not be assumed to alleviate feelings of social isolation.Interventions should focus on personalized psychosocial input aimed at helping the person with multiple sclerosis regain a sense of self and their place in the world.

A Streamlined Protocol for Wheat (Triticum aestivum) Protoplast Isolation and Transformation With CRISPR-Cas Ribonucleoprotein Complexes.

The genetic engineering method CRISPR has been touted as an efficient, inexpensive, easily used, and targeted genetic modification technology that is widely suggested as having the potential to solve many of the problems facing agriculture now and in the future. Like all new technologies, however, it is not without challenges. One of the most difficult challenges to anticipate and detect is gene targets that are inaccessible due to the chromatin state at their specific location. There is currently no way to predict this during the process of designing a sgRNA target, and the only way to detect this issue before spending time and resources on full transformations is to test the cleavage ability of the sgRNA in vivo. In wheat, this is possible using protoplast isolation and PEG transformation with Cas9 ribonucleoprotein complexes. Therefore, we have developed a streamlined protocol for testing the accessibility of sgRNA targets in wheat. The first steps involve digesting wheat leaf tissue in an enzymatic solution and then isolating viable protoplasts using filters and a sucrose gradient. The protoplasts are then transformed using Cas9 ribonucleoprotein complexes via PEG-mediated transformation. DNA is isolated from the CRISPR-Cas-edited protoplasts and PCR is performed to amplify the gene target region. The PCR product is then used to assess the editing efficiency of the chosen sgRNA using Sanger sequencing. This simplified protocol for the isolation and transformation of wheat protoplast cells using Cas9 ribonucleoprotein complexes streamlines CRISPR transformation projects by allowing for a fast and easy test of sgRNA accessibility in vivo.

Falls in People with Multiple Sclerosis: Risk Identification, Intervention, and Future Directions.

Falls are highly prevalent in people with multiple sclerosis (MS) and result in a range of negative consequences, such as injury, activity curtailment, reduced quality of life, and increased need for care and time off work. This narrative review aims to summarize key literature and to discuss future work needed in the area of fall prevention for people with MS. The incidence of falls in people with MS is estimated to be more than 50%, similar to that in adults older than 80 years. The consequences of falls are considerable because rate of injury is high, and fear of falling and low self-efficacy are significant problems that lead to activity curtailment. A wide range of physiological, personal, and environmental factors have been highlighted as potential risk factors and predictors of falls. Falls are individual and multifactorial, and, hence, approaches to interventions will likely need to adopt a multifactorial approach. However, the literature to date has largely focused on exercise-based interventions, with newer, more comprehensive interventions that use both education and exercise showing promising results. Several gaps in knowledge of falls in MS remain, in particular the lack of standardized definitions and outcome measures, to enable data pooling and comparison. Moving forward, the involvement of people with MS in the design and evaluation of programs is essential, as are approaches to intervention development that consider implementation from the outset.

Effectiveness of non-pharmacological interventions to treat orthostatic hypotension in elderly people and people with a neurological condition: a systematic review.

OBJECTIVE: The objective of this review was to summarize the best available evidence regarding the effectiveness of non-pharmacological interventions to treat orthostatic hypotension (OH) in elderly people and people with a neurological condition. INTRODUCTION: Orthostatic hypotension is common in elderly people and people with a neurological condition and can interfere with or limit rehabilitation. Non-pharmacological interventions to treat OH could allow for longer and earlier mobilization, which is recommended in national clinical guidelines for rehabilitation in the acute or sub-acute phase following stroke or other neurological conditions. INCLUSION CRITERIA: The review considered people aged 50 years and older, and people aged 18 years and elderly people with a neurological condition. Non-pharmacological interventions to treat OH included compression garments, neuromuscular stimulation, physical counter-maneuvers, aerobic or resistance exercises, sleeping with head tilted up, increasing fluid and salt intake, and timing and size of meals. The comparator was usual care, no intervention, pharmacological interventions, or other non-pharmacological interventions. Outcome measures included systolic blood pressure, diastolic blood pressure, heart rate, cerebral blood flow, observed/perceived symptoms, duration of standing or sitting in minutes, tolerance of therapy, functional ability, and adverse events/effects. METHODS: Databases for published and unpublished studies available in English up to April 2018 with no lower date limit were searched. Critical appraisal was conducted using standardized instruments from JBI. Data were extracted using standardized tools designed for quantitative studies. Where appropriate, studies were included in a meta-analysis; otherwise, data were presented in a narrative form due to heterogeneity. RESULTS: Forty-three studies - a combination of randomized controlled trials (n = 13), quasi-experimental studies (n = 28), a case control study (n = 1), and a case report (n = 1) - with 1069 participants were included. Meta-analyses of three interventions (resistance exercise, electrical stimulation, and lower limb compression bandaging) showed no significant effect of these interventions. Results from individual studies indicated physical maneuvers such as leg crossing, leg muscle pumping/contractions, and bending forward improved orthostatic hypotension. Abdominal compression improved OH. Sleeping with head up in combination with pharmacological treatment was more effective than sleeping with head up alone. Eating smaller, more frequent meals was effective. Drinking 480 mL of water increased blood pressure. CONCLUSIONS: The review found mixed results for the effectiveness of non-pharmacological interventions to treat OH in people aged 50 years and older, and people with a neurological condition. There are several non-pharmacological interventions that may be effective in treating OH, but not all have resulted in clinically meaningful changes in outcome. Some may not be suitable for people with moderate to severe disability; therefore, it is important for clinicians to consider the patient's abilities and impairments when considering which non-pharmacological interventions to implement.
