RESUMEN

Background: We developed a 29-item Questionnaire, Long-term Unmet Needs in MS (LUN-MS) to identify the unmet needs of people with multiple sclerosis (pwMS). Objective: To assess acceptability, test-retest reliability, internal consistency, and validity of the LUN-MS. Methods: Participants completed the LUN-MS and MSIS-29 twice, four weeks apart. Acceptability was assessed by looking at the response rate in each time point. Reliability was calculated by comparing the response during the two time points using Cohen's weighted kappa. Using principal component analysis, the dimensionality of the questionnaire's items was reduced, to five domains and the internal consistency of each domain was assessed using Cronbach's alpha. Concurrent validity was tested by comparing the total LUN-MS score against MSIS-29 and EQ-5D-3L using Pearson's product-moment correlation coefficient. Results: Among 88 participants, rate of completion at time points-1 and 2 was 96 and 80% respectively. Test-retest reliability for individual items was between fair to near-perfect (weighted Cohen's kappa 0.39-0.81). The unmet needs could be divided into five internally consistent domains (Cronbach's alpha 0.83-0.74): neuropsychological, ambulation, physical, interpersonal relationship and informational. Concurrent validity with MSIS-29 (r = 0.705, P < .001) and EQ-5D-3L (r = 0.617, P < .001) were good. Conclusion: LUN-MS is a reliable, valid, and acceptable tool to identify the unmet needs of pwMS.

RESUMEN

Background: Remote ischemic conditioning (RIC), exposure of body parts to brief periods of circulatory occlusion and reperfusion, has been shown to improve cardiovascular responses to exercise in healthy individuals but its effects in people with MS are unknown. Objective: This study aimed to assess the effect of RIC on heart rate responses to walking in people with MS. Design: Double blind randomized controlled trial. Setting: Multiple sclerosis clinic of tertiary care center teaching hospital in the United Kingdom. Methods: Three cycles of RIC were delivered by occluding the upper arm with a blood pressure cuff inflated to a pressure of 30 mmHg above the systolic blood pressure. In the sham group, the blood pressure cuff was inflated to 30 mmHg below diastolic blood pressure. Heart rate responses to the 6-minute walk test (6MWT), the tolerability of RIC using a numerical rating scale for discomfort (0-10), and adverse events were studied. Results: Seventy-five participants (RIC -38 and Sham-37) completed the study. RIC was well tolerated. Compared to sham, RIC significantly decreased the rise in heart rate (P = 0.04) and percentage of predicted maximum heart rate (P = 0.016) after the 6MWT. Conclusion: RIC was well tolerated and improved the heart rate response to walking in people with MS. Further studies on RIC in the management of MS are needed.

RESUMEN

Objectives: The aim of this study was to assess the cognitive abilities of people with spinal cord injury (SCI) using the Edinburgh Cognitive and Behavior Amyotrophic Lateral Sclerosis Screen (ECAS), a tool designed for testing cognition in individuals with limited hand motor function. The impact of cognitive dysfunction on quality of life was also assessed. Methods: Forty-one patients with SCI were assessed using ECAS, the brief version of the World Health Organisation Quality of Life questionnaire (WHOQOL-BREF), and the Spinal Cord Independence Measure. Results: Overall, 28 of the 41 participants scored below the cut-off threshold for normal population in ECAS. The domains affected were language, 63%; memory, 51%; executive function, 44%; verbal fluency, 44%; and visuospatial skills, 24%. On multiple regression analysis, the ECAS total score moderately strongly explained the variance in the WHOQOL-BREF psychological (ß = 0.428, t = 2.958, P = 0.005) and environmental (ß = 0.411, t = 2.819, P = 0.008) domains. ECAS memory scores independently influenced WHOQOL-BREF physical (ß = 0.398, t = 2.67, P = 0.011) and environmental (ß = 0.37, t = 2.697, P = 0.010) domains. WHOQOL-BREF psychological scores were significantly influenced by ECAS executive scores (ß = 0.415, t = 2.85, P = 0.007), whereas the social domain was not significantly influenced by ECAS scores. Conclusions: It was feasible to use ECAS in individuals with SCI. Cognitive ability influenced the quality of life of people with SCI.

RESUMEN

BACKGROUND: People living with long-term neurological conditions (LTNC) often require palliative care. Rehabilitation medicine specialists often coordinate the long-term care of these patients. OBJECTIVE: The aim of the present review was to undertake systematic literature searches to identify the evidence on palliative care for people with LTNC to guide rehabilitation medicine specialists caring for these patients in the UK. METHODS: We searched for evidence for (1) discussion of end of life, (2) planning for end-of-life care, (3) brief specialist palliative care interventions, (4) support for family and carers, (5) training of rehabilitation medicine specialists in palliative care, and (6) commissioning of services. The databases searched were MEDLINE, EMBASE, CINAHL, PsycINFO, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Database of Abstracts of Reviews of Effects, NHS Economic Evaluation Database and Health Technology Assessment Database. Evidence was assimilated using a simplified version of the Grading of Recommendations Assessment, Development and Evaluation method. RESULTS: We identified 2961 records through database searching for neurological conditions and 1261 additional records through database searches for specific symptoms. We removed duplicate records and conference presentations. We screened 3234 titles and identified 330 potentially relevant abstracts. After reading the abstracts we selected 34 studies for inclusion in the evidence synthesis. CONCLUSIONS: From the evidence reviewed we would like to recommend that we move forward by establishing a closer working relationship with specialists in palliative care and rehabilitation medicine and explore the implications for cross-specialty training.

RESUMEN

Brain-computer interfaces (BCIs) have recently been shown to be clinically effective as a novel method of stroke rehabilitation. In many BCI-based studies, the activation of the ipsilesional hemisphere was considered a key factor required for motor recovery after stroke. However, emerging evidence suggests that the contralesional hemisphere also plays a role in motor function rehabilitation. The objective of this study is to investigate the effectiveness of the BCI in detecting motor imagery of the affected hand from contralesional hemisphere. We analyzed a large EEG dataset from 136 stroke patients who performed motor imagery of their stroke-impaired hand. BCI features were extracted from channels covering either the ipsilesional, contralesional or bilateral hemisphere, and the offline BCI accuracy was computed using 10 [Formula: see text] 10-fold cross-validations. Our results showed that most stroke patients can operate the BCI using either their contralesional or ipsilesional hemisphere. Those with the ipsilesional BCI accuracy of less than 60% had significantly higher motor impairments than those with the ipsilesional BCI accuracy above 80%. Interestingly, those with the ipsilesional BCI accuracy of less than 60% achieved a significantly higher contralesional BCI accuracy, whereas those with the ipsilesional BCI accuracy more than 80% had significantly poorer contralesional BCI accuracy. This study suggests that contralesional BCI may be a useful approach for those with a high motor impairment who cannot accurately generate signals from ipsilesional hemisphere to effectively operate BCI.

RESUMEN

This paper provides an overview of the usability engineering process and relevant standards informing the development of medical devices, together with adaptations to accommodate situations such as global pandemics where use of traditional face-to-face methods is restricted. To highlight some of those adaptations, a case study of a project developing a novel electronic rehabilitation device is referenced, which commenced in November 2020 amidst the COVID-19 pandemic. The Sheffield Adaptive Patterned Electrical Stimulation (SHAPES) project, led by Sheffield Teaching Hospitals NHS Foundation Trust (STH), aimed to design, manufacture and trial an intervention for use to treat upper arm spasticity after stroke. Presented is an outline and discussion of the challenges experienced in developing the SHAPES health technology intended for at-home use by stroke survivors and in implementing usability engineering approaches. Also highlighted, are the benefits that arose, which can offer easier involvement of vulnerable users and add flexibility in the ways that user feedback is sought. Challenges included: restricted travel; access to usual prototyping facilities; social distancing; infection prevention and control; availability of components; and changing work pressures and demands. Whereas benefits include: less travel; less time commitment; and greater scope for participants with restricted mobility to participate in the process. The paper advocates a more flexible approach to usability engineering and outlines the onward path for development and trialling of the SHAPES technology.

RESUMEN

Background: People with Multiple Sclerosis (pwMS) prioritise gait as the most valuable function to be affected by MS. Physiotherapy plays a key role in managing gait impairment in MS. There is little evidence on the effectiveness of physiotherapy for severe MS. Objective: To undertake a systematic review and meta-analysis of the literature to identify evidence for the effectiveness of physiotherapy for gait impairment in severe MS. Methods. The available literature was systematically searched, using a predetermined protocol, to identify research studies investigating a physiotherapy intervention for mobility in people with severe MS (EDSS ≥ 6.0). Data on mobility related endpoints was extracted. Meta-analysis was performed where a given mobility end point was reported in at least 3 studies. Results: 37 relevant papers were identified, which included 788 pwMS. Seven mobility-related endpoints were meta-analysed. Robot-Assisted Gait Training (RAGT) was found to improve performance on the 6-minute walk test, 10-metre walk test, fatigue severity scale, and Berg Balance Scale. Neither body weight supported training nor conventional walking training significantly improved any mobility-related outcomes. Conclusion: Physiotherapy interventions are feasible for mobility in severe MS. There is some evidence for the effectiveness of RAGT.

RESUMEN

Guidance and protocols of end-of-life care have been directed towards the care of patients with cancer. It is possible to extrapolate some of these to people with long-term neurological conditions, but there are obvious differences. Neurological conditions have widely different time courses of progression, making the timing of these discussions challenging. The common issues around end-of-life care include knowing when to start discussions, approaching advance planning, managing common symptoms, diagnosing the dying phase, withdrawing life-sustaining treatments, providing support for family and carers and judging how to involve specialist palliative care teams. End-of-life care needs close collaboration between neurology, specialist palliative care and general practice.

RESUMEN

BACKGROUND: Fatigue is a widely experienced, incapacitating symptom of MS. It hinders daily functioning and has deleterious effects on quality of life. The UK MS Register is an online registry of over 20,000 participants with MS. The aim of this study was to estimate the prevalence, predictors, and impact of fatigue on people with MS using data from the UKMS register. METHODS: All participants who completed the Fatigue Severity Scale (FSS), WebEDSS, Hospital Anxiety and Depression Scale (HADS) within 28 days of each other were selected from the UK MS Register. Data on age, gender, duration and type of MS, use of disease modifying drugs and comorbidities were obtained from the UKMS register. We categorised people with FSS score of 5 or more as with fatigue and those with scores of 4 or less as without fatigue. Descriptive statistics and logistical and multiple regressions were used to explore predictors of fatigue and the effect of fatigue on mobility (MS Walking Scale), physical and psychological aspects of life (MS Impact Scale) and quality of life (European Quality of Life 5D-3 L). RESULTS: Amongst the 20,946 participants of the UK MS registry, 4620 completed FSS. Out of these, 775 (mean age= 54.71 years, SD= 10.90; mean duration of MS diagnosis =13.21 years, SD=9.75) had completed the FSS, Web EDSS and Hospital Anxiety and Depression Scale within 28 days of each other. 427 (55.1%) of pwMS had a FSS score >5 consistent with clinical fatigue. Logistic regression analysis showed that depression (p=<0.001), duration of MS (p = 0.017), secondary progressive MS (p = 0.001) and EDSS (p=<0.001) predicted fatigue. FSS scores had a significant negative impact on both psychological (p > 0.001) and physical (p > 0.001) domains of the MS Impact scale, MS walking scale (p = 0.003) and EQoL (p = 0.005). CONCLUSIONS: Fatigue was a common symptom amongst people with MS. Depression, longer duration of MS, secondary progressive MS, and high EDSS predicted fatigue. Fatigue had an adverse effect on physical activities, mobility, psychological wellbeing, and quality of life of people with MS.

RESUMEN

Background. A number of recent randomized controlled trials reported the efficacy of brain-computer interface (BCI) for upper-limb stroke rehabilitation compared with other therapies. Despite the encouraging results reported, there is a significant variance in the reported outcomes. This paper aims to investigate the effectiveness of different BCI designs on poststroke upper-limb rehabilitation. Methods. The effect sizes of pooled and individual studies were assessed by computing Hedge's g values with a 95% confidence interval. Subgroup analyses were also performed to examine the impact of different BCI designs on the treatment effect. Results. The study included 12 clinical trials involving 298 patients. The analysis showed that the BCI yielded significant superior short-term and long-term efficacy in improving the upper-limb motor function compared to the control therapies (Hedge's g = 0.73 and 0.33, respectively). Based on our subgroup analyses, the BCI studies that used the intention of movement had a higher effect size compared to those used motor imagery (Hedge's g = 1.21 and 0.55, respectively). The BCI studies using band power features had a significantly higher effect size than those using filter bank common spatial patterns features (Hedge's g = 1.25 and - 0.23, respectively). Finally, the studies that used functional electrical stimulation as the BCI feedback had the highest effect size compared to other devices (Hedge's g = 1.2). Conclusion. This meta-analysis confirmed the effectiveness of BCI for upper-limb rehabilitation. Our findings support the use of band power features, the intention of movement, and the functional electrical stimulation in future BCI designs for poststroke upper-limb rehabilitation.

RESUMEN

Remote ischaemic conditioning (RIC) refers to a process whereby periods of intermittent ischaemia, typically via the cyclical application of a blood pressure cuff to a limb at above systolic pressure, confers systemic protection against ischaemia in spatially distinct vascular territories. The mechanisms underlying this have not been characterised fully but have been shown to involve neural, hormonal and systemic inflammatory signalling cascades. Preclinical and early clinical studies have been promising and suggest beneficial effects of RIC in acute ischaemic stroke, symptomatic intracranial stenosis and vascular cognitive impairment. Through systematic searches of several clinical trials databases we identified 48 active clinical trials of RIC in ischaemic stroke, intracerebral haemorrhage and subarachnoid haemorrhage. We summarise the different RIC protocols and outcome measures studied in ongoing clinical trials and highlight which studies are most likely to elucidate the underlying biological mechanisms of RIC and characterise its efficacy in the near future. We discuss the uncertainties of RIC including the optimal frequency and duration of therapy, target patient groups, cost-effectiveness, the confounding impact of medications and the absence of a clinically meaningful biomarker of the conditioning response. With several large clinical trials of RIC expected to report their outcomes within the next 2 years, this review aims to highlight the most important studies and unanswered questions that will need to be addressed before this potentially widely accessible and low-cost intervention can be used in clinical practice.

RESUMEN

OBJECTIVE: Mobility assessment is critical in the clinical management of people with Multiple Sclerosis (pwMS). Instrumented gait analysis provides a plethora of metrics for quantifying concurrent factors contributing to gait deterioration. However, a gait model discriminating underlying features contributing to this deterioration is lacking in pwMS. This study aimed at developing and validating such a model. METHODS: The gait of 24 healthy controls and 114 pwMS with mild, moderate, or severe disability was measured with inertial sensors on the shanks and lower trunk while walking for 6 minutes along a hospital corridor. Twenty out of thirty-six initially explored metrics computed from the sensor data met the quality criteria for exploratory factor analysis. This analysis provided the sought model, which underwent a confirmatory factor analysis before being used to characterize gait impairment across the three disability groups. RESULTS: A gait model consisting of five domains (rhythm/variability, pace, asymmetry, and forward and lateral dynamic balance) was revealed by the factor analysis, which was able to highlight gait abnormalities across the disability groups: significant alterations in rhythm/variability-, asymmetry-, and pace-based features were present in the mild group, but these were more profound in the moderate and severe groups. Deterioration in dynamic balance-based features was only noted in pwMS with a moderate and severe disability. CONCLUSION: A conceptual model of gait for disease-specific mobility assessment in pwMS was successfully developed and tested. SIGNIFICANCE: The new model, built with metrics that represent gait impairment in pwMS, highlighted clinically relevant changes across different disability levels, including those with no clinically observable walking disability. This shows the clear potential as a monitoring biomarker in pwMS.

RESUMEN

INTRODUCTION: Entrapment neuropathies of upper limbs such as carpal tunnel and cubital tunnel syndromes are common in the general population. Identification of entrapment neuropathies of upper limbs in patients with multiple sclerosis can be clinically challenging as signs and symptoms could be attributed to multiple sclerosis. People at later stages of multiple sclerosis use mobility aids and wheelchairs. Weakness of hands in this cohort due to entrapment neuropathies could adversely affect their mobility and independence. METHODS: This was a retrospective review of records of patients with multiple sclerosis referred for clinical neurophysiological studies with clinical suspicion of upper limb entrapment neuropathies over a 10-year period. We collected demographic details, clinical features, clinical neurophysiological data and details of aids and appliances used for mobility. RESULTS: Among 71 patients, 38 (53.5%) patients had at least one entrapment neuropathy of upper limb confirmed by clinical neurophysiological studies. Twelve (31%) patients had median nerve entrapment, 20 (53%) had ulnar nerve entrapment and six (16%) had both. Risk of ulnar nerve entrapment was significantly higher in patients using a powered wheelchair (odds ratio 5.7, 95% confidence interval (1.7-18.7, p = 0.0037). DISCUSSION: Entrapment neuropathies should be considered in patients with multiple sclerosis reporting sensory and motor symptoms of hands.

RESUMEN

BACKGROUND: Around a third of people with multiple sclerosis (MS) experience dysphagia. There is a need for disease-specific information on survival following placement of gastrostomy tube in people with MS. OBJECTIVE: We aimed to study survival following gastrostomy in patients with MS. METHODS: We reviewed medical records, home enteral feeding database and death certificates of people with MS who had gastrostomy from 2005 to 2017. Cox regression analysis was performed to identify independent predictors associated with mortality after gastrostomy. RESULTS: Median survival of 53 patients with MS after gastrostomy was 21.73 months. Median duration of hospital stay after gastrostomy was 14 days (IQR 5.25, 51.5). Survival at 30 days, 3 months, 1, 2, 5 and 10 years were 100% (53/53), 98.1% (52/53), 81.1% (43/53), 54.7% (29/53), 22.4% (11/49) and 6.8% (3/44), respectively. Of 53 patients, 24 died due to respiratory tract infection. Patients who had gastrostomy tube before 50 years of age survived longer (median 28.48 months) compared with those who had the gastrostomy after age 50 years (median 17.51 months) (p = 0.040). CONCLUSION: Around 54% of patients with MS survived two or more years following gastrostomy. Younger patients had better survival. The most frequent cause of death was respiratory infection.

RESUMEN

BACKGROUND: Remote ischaemic preconditioning (RIPC) is the exposure of body parts to brief periods of circulatory occlusion and reperfusion. Recent studies have also shown that RIPC can improve exercise performance in healthy individuals. OBJECTIVE: This study aimed to assess the effect of RIPC on walking in people with multiple sclerosis (MS). METHODS: This was a double-blind randomised controlled clinical trial. We used three cycles of RIPC delivered by occluding the upper arm with a blood pressure (BP) cuff inflated to a pressure of 30 mm Hg above the systolic BP. In patients in the sham intervention group, the BP cuff was inflated only to 30 mm Hg below diastolic BP. Outcome measures included the Six-Minute Walk Test (6MWT), gait speed, the Borg rate of perceived exertion (RPE) scale, the tolerability of the RIPC using a Numerical Rating Scale for discomfort from 0 to 10, and adverse events. We identified responders meeting the minimal clinically important difference (MCID) established in the literature in each group. RESULTS: Seventy-five participants completed the study (RIPC: 38 and Sham: 37). The distance walked during the 6MWT improved by 1.9% in the sham group and 5.7% in the RIPC group (p=0.012). The number of responders meeting MCID criteria in the RIPC group was significantly greater compared with the sham intervention group. No serious adverse events occurred. CONCLUSION: Single cycle of RIPC resulted in immediate improvement in walking distances during 6MWT in people with MS. TRIAL REGISTRATION NUMBERS: NCT03153553.

RESUMEN

Inertial measurement units (IMUs) allow accurate quantification of gait impairment of people with multiple sclerosis (pwMS). Nonetheless, it is not clear how IMU-based metrics might be influenced by pragmatic aspects associated with clinical translation of this approach, such as data collection settings and gait protocols. In this study, we hypothesised that these aspects do not significantly alter those characteristics of gait that are more related to quality and energetic efficiency and are quantifiable via acceleration related metrics, such as intensity, smoothness, stability, symmetry, and regularity. To test this hypothesis, we compared 33 IMU-based metrics extracted from data, retrospectively collected by two independent centres on two matched cohorts of pwMS. As a worst-case scenario, a walking test was performed in the two centres at a different speed along corridors of different lengths, using different IMU systems, which were also positioned differently. The results showed that the majority of the temporal metrics (9 out of 12) exhibited significant between-centre differences. Conversely, the between-centre differences in the gait quality metrics were small and comparable to those associated with a test-retest analysis under equivalent conditions. Therefore, the gait quality metrics are promising candidates for reliable multi-centric studies aiming at assessing rehabilitation interventions within a routine clinical context.

RESUMEN

This study contributes to the growing literature linking physical characteristics and behavioral tendencies by advancing the current debate on whether a person's facial width-to-height ratio (fWHR) predicts a variety of antisocial tendencies. Specifically, our large-scale study avoided the social-desirability bias found in self-reports of behavioral tendencies by capturing survey data not only from more than 1,000 business executives but also from evaluators who reported knowing the focal individuals well. With this improved research design, and after conducting a variety of analyses, we found very little evidence of fWHR predicting antisocial tendencies. In light of prior research linking fWHR to social perceptions of evaluators, our results are suggestive of an evolutionary mismatch, whereby a physical characteristic once tied to antisocial tendencies in ancestral environments is-in modern environments-not predictive of such behaviors but instead predictive of biased perceptions.

RESUMEN

BACKGROUND: Multiple Sclerosis Quality-of-Life Questionnaire-54 (MSQoL-54) is a disease-specific instrument for assessing health-related quality of life (HRQoL). Due to the number of items, the time taken to complete it is long. A shorter 29-item version, Multiple Sclerosis Quality-of-Life Questionnaire-29 (MSQoL-29) is yet to be evaluated in English. OBJECTIVE: To assess reliability and acceptability of English version of MSQoL-29. METHODS: Among 100 participants with MS who first completed both MSQoL-54 and MSQoL-29, 91 completed MSQoL-29 after 4-8 weeks. We looked for internal consistency (Cronbach's alpha), acceptability, reliability (intraclass correlation coefficients (ICCs)) and agreement (Bland-Altman plots). RESULTS: ICCs were strongly positive between MSQoL-54 and MSQoL-29 (Physical Health Composite (PHC) -ICC = 0.914, confidence interval (CI) = 0.872-0.942; Mental Health Composite (MHC) - ICC = 0.875, CI = 0.814-0.916) and between the two MSQoL-29 (PHC - ICC = 0.970, CI = 0.955-0.980; MHC - ICC = 0.937, CI = 0.904-0.958). On Bland-Altman plots, the MSQoL-29 scores of 95% of participants during two visits were within the limits of agreement (LOAs). Time taken to complete MSQoL-29 was 7.2 ± 2.9 minutes and MSQoL-54 was 19.79 ± 5.4 minutes (p = 0.0001). CONCLUSION: MSQoL-29 has good test-retest reliability in English-speaking population and was quicker to complete.

RESUMEN

STUDY DESIGN: Single-blind, sham-controlled, crossover randomized feasibility study OBJECTIVES: (1) Assess the feasibility of a full-scale trial of intermittent theta-burst stimulation (iTBS) for upper-limb sensorimotor dysfunction following spinal cord injury (SCI). (2) Determine the safety and tolerability of iTBS over primary motor cortex on upper-limb function in people with spinal cord injury (SCI). SETTING: Large Tertiary Spinal Injuries Centre METHODS: Participants with incomplete SCI, suffering with upper-limb spasticity were recruited and randomized to receive active/sham iTBS over the hand representation of the primary motor cortex. The intervention was delivered in 10 sessions over a 2-week period, followed by a 2-week washout, before being crossed over to receive the alternative intervention for the same number of sessions. Feasibility was assessed by pre-specified criteria which included recruitment rate of 3 participants per month, 10 completed interventions and 10 complete data sets for 15 recruited participants with no serious adverse events. Secondary outcomes included preliminary data collection for spasticity, pain and sensorimotor function. RESULTS: Twelve participants were recruited over 10 weeks (i.e., 4.8 per month), with 11 randomized and 10 completing the intervention protocol with no serious adverse events. Eight complete data sets were obtained as two participants failed to attend follow-up. Data from 10 participants were analyzed, with one early dropout due to an unrelated adverse event. CONCLUSIONS: It is safe and feasible to conduct a full-scale trial. Whilst iTBS has shown promising results, further research optimizing the intervention is required to improve anticipated clinical efficacy.
