Tailored leadership training in emergency medicine: qualitative exploration of the impact of the EMLeaders programme on consultants and trainees in England.

BACKGROUND: Emergency medicine (EM) consultants are expected to provide leadership to facilitate optimal clinical results, effective teamwork and learning. To foster leadership skills, the Emergency Medicine Leadership Programme (EMLeaders) was launched in 2018 by the Royal College of Emergency Medicine (RCEM), Health Education England and National Health Service England. A mixed-methods evaluation of EMLeaders was commissioned to assess the impact at the strategic, team and individual levels. This paper reports the qualitative evaluation component. METHODS: Qualitative data collected from 2021 to 2022 were drawn from an online survey of RCEM members in England, which included four open questions about leadership training. At the end of the survey, participants were asked to share contact details if willing to undertake an in-depth qualitative interview. Interviews explored perceptions of the programme and impact of curriculum design and delivery. Data were analysed thematically against the Kirkpatrick framework, providing in-depth understanding. RESULTS: There were 417 survey respondents, of whom 177 had participated in EMLeaders. Semistructured interviews were completed with 13 EM consultants, 13 trainees and 1 specialty and associate specialist doctor. EMLeaders was highly valued by EM consultants and trainees, particularly group interaction, expert facilitation and face-to-face practical scenario work. Consultant data yielded the themes: we believe in it; EM relevance is key; on a leadership journey; shaping better leaders; and a broken system. Challenges were identified in building engagement within a pressured workplace system and embedding workplace role modelling. Trainees identified behavioural shift in themselves following the programme but wanted more face-to-face discussions with senior colleagues. Key trainee themes included value in being together, storytelling in leadership, headspace for the leadership lens and survival in a state of collapse. CONCLUSION: The development of leadership skills in EM is considered important. The EMLeaders programme can support leadership learning but further embedding is needed.

Physical therapy for facial nerve paralysis (Bell's palsy): An updated and extended systematic review of the evidence for facial exercise therapy.

OBJECTIVE: To conduct a systematic review of the effectiveness of facial exercise therapy for facial palsy patients, updating an earlier broader Cochrane review; and to provide evidence to inform the development of telerehabilitation for these patients. DATA SOURCES: MEDLINE, EMBASE, CINAHL, Cochrane Library, PEDro and AMED for relevant studies published between 01 January 2011 and 30 September 2020. METHODS: Predetermined inclusion/exclusion criteria were utilised to shortlist abstracts. Two reviewers independently appraised articles, systematically extracted data and assessed the quality of individual studies and reviews (using GRADE and AMSTAR-2, respectively). Thematic analysis used for evidence synthesis; no quantitative meta-analysis conducted. The review was registered with PROSPERO (CRD42017073067). RESULTS: Seven new randomised controlled trials, nine observational studies, and three quasi-experimental or pilot studies were identified (n = 854 participants). 75% utilised validated measures to record changes in facial function and/or patient-rated outcomes. High-quality trials (4/7) all reported positive impacts; as did observational studies rated as high/moderate quality (3/9). The benefit of therapy at different time points post-onset and for cases of varying clinical severity is discussed. Differences in study design prevented data pooling to strengthen estimates of therapy effects. Six new review articles identified were all rated critically low quality. CONCLUSION: The findings of this targeted review reinforce those of the earlier more general Cochrane review. New research studies strengthen previous conclusions about the benefits of facial exercise therapy early in recovery and add to evidence of the value in chronic cases. Further standardisation of study design/outcome measures and evaluation of cost-effectiveness are recommended.

A feasibility randomised controlled trial of a Fibromyalgia Self-management Programme for adults in a community setting with a nested qualitative study (FALCON).

BACKGROUND: Fibromyalgia is a condition associated with widespread musculoskeletal pain, fatigue and sleep problems. Fibromyalgia treatment guidelines recommend non-pharmacological interventions and the development of self-management skills. An example of a programme that fits these guidelines is the Fibromyalgia Self-management Programme (FSMP) which consists of one 2.5-hour weekly session over six successive weeks and includes education about fibromyalgia, goal setting, pacing, sleep hygiene and nutritional advice. The FSMP is currently provided in a secondary care hospital setting and co-delivered by a multidisciplinary team. Delivery in a primary care setting has the potential to improve the accessibility of the programme to people with fibromyalgia. Therefore, this feasibility study aimed to determine the practicality and acceptability of conducting a future definitive randomised controlled trial of the FSMP in a community setting. METHOD: An exploratory, parallel-arm, one-to-one, randomised controlled trial. Participants were recruited from general practices across South West England, and the FSMP was co-delivered by physiotherapists and occupational therapists across two community sites. To determine the outcome measures for a future definitive trial several were tested. The Revised Fibromyalgia Impact Questionnaire, Arthritis Self-Efficacy Scale-8, Chalder Fatigue Scale, Short form 36, 5-Level EQ-5D version and Jenkins Sleep Scale were collected at baseline, 6 weeks and 6 months. Semi-structured interviews were conducted with patient participants, occupational therapists and physiotherapists to explore the acceptability and feasibility of delivering the FSMP in a community setting. RESULTS: A total of 74 participants were randomised to the FSMP intervention (n = 38) or control arm (n = 36). Attrition from the trial was 42% (31/74) at 6 months. A large proportion of those randomised to the intervention arm (34%, 13/38) failed to attend any sessions with six of the 13 withdrawing before the intervention commenced. The proportion of missing values was small for each of the outcome measures. Three overarching themes were derived from the interview data; (1) barriers and facilitators to attending the FSMP; (2) FSMP content, delivery and supporting documentation; and (3) trial processes. CONCLUSION: It is feasible to recruit people with fibromyalgia from Primary Care to participate in a randomised controlled trial testing the FSMP in a community setting. However, improvement in trial attrition and engagement with the intervention is needed. TRIAL REGISTRATION: The trial is registered with ISRCTN registry and was assigned on 29/04/2019. The registration number is ISRCTN10824225.

Foundational Research Could Improve Future Transcutaneous Electrical Nerve Stimulation Evaluations.

Background and objectives: There is a lack of good quality evidence regarding the effectiveness of transcutaneous electrical nerve stimulation (TENS) for chronic musculoskeletal pain, including chronic low back pain. High quality randomised controlled trials (RCTs) have been called for to establish effectiveness over and above placebo and some guidance has already been offered regarding the design of such trials. This article expands the discussion regarding the design of future TENS trials. There is qualitative evidence of the complexity of TENS as an intervention which should be considered in future TENS evaluations. This complexity includes multiple benefits reported by patients, depending on their chosen contexts of TENS use. The ideal content and delivery of support for patients to optimise TENS use also lacks consensus. There is no evidence that a TENS education package has been designed to support the complex set of behaviours and choices which experienced users suggest are required to optimise TENS benefits. Finally, clinical and research outcomes have not been contextualised and related to the specific strategies of use. Conclusions: We suggest that research is required to develop consensus about the content and delivery of training in TENS use for patients who live with pain, informed by the experience of patients, clinicians, and researchers. Once a consensus about the content of TENS training has been reached, there is then a need to develop a TENS training course (TTC) based on this content. An effective and acceptable TTC is needed to develop the knowledge and skills required to optimise TENS use, supporting patients to build confidence in using TENS in everyday life situations with the aim of reducing the impact of chronic pain on function and quality of life. Further research is required to extend the evidence base regarding appropriate, contextualised TENS patient-reported outcomes.

Intra-rater reliability and smallest detectable change of compression sonoelastography in quantifying the material properties of the musculoskeletal system.

Musculoskeletal conditions can change tissue elasticity. Knowledge of musculoskeletal elasticity could therefore aid clinical diagnosis and management. Sonoelastography is an ultrasound-based system that examines the material properties of tissues, and it may be useful in musculoskeletal practice. Therefore, it is important to establish its clinimetric properties. This study aimed to explore the intra-rater reliability and the smallest detectable changes of sonoelastography in examining musculoskeletal structures. A quantitative reliability design was used to examine 22 healthy participants using a compression sonoelastography system that produces color-coded images. The deltoid, biceps brachii, brachioradialis, rectus femoris, gastrocnemius medius muscles, and Achilles tendon were examined twice at 1-hr intervals to assess the intra-rater reliability. The sonoelastography images were analyzed using the strain index, strain ratio, and color pixels. The intra-rater reliability and the smallest detectable changes of each outcome variable were determined. The intra-class correlation coefficient was used to quantify the repeatability of the measurements, and the smallest detectable changes were calculated to determine clinically important differences above the error of measurement. The intra-rater reliability for the strain index, strain ratio, and color pixel analysis ranged from moderate to excellent (intra-class correlation coefficients: .734-.950, .776-.921, and .754-.990, respectively), with color pixel analysis demonstrating the highest reliability. The smallest detectable changes were determined for all structures, including the Achilles tendon (0.11 for the higher boundary of the strain index, 1.80 for the strain ratio, and 2.90% for red pixels, representing soft tissues). Color pixel analysis may be more reliable for sonoelastography interpretation compared with the strain index and strain ratio. The calculated smallest detectable changes could be used to identify clinically important differences.

Body Perception Disturbance and Pain Reduction in Longstanding Complex Regional Pain Syndrome Following a Multidisciplinary Rehabilitation Program.

OBJECTIVE: Clinical guidelines for the treatment of complex regional pain syndrome recommend multidisciplinary rehabilitation, yet limited evidence exists to support the effectiveness of this approach. Body perception disturbance, a common and debilitating feature of complex regional pain syndrome, is recommended by guidelines as important to treat. However, no study has yet explored whether disturbances change in response to multidisciplinary rehabilitation. We aimed to determine whether there is a change in body perception disturbance and pain following a two-week multidisciplinary rehabilitation program for complex regional pain syndrome. METHODS: Retrospective clinical data from complex regional pain syndrome patients who completed the program between September 2014 and December 2016 were extracted and anonymized. Data collected pre- and post rehabilitation comprising the Bath Body Perception Disturbance scale and a pain intensity numerical rating scale were analyzed. RESULTS: Thirty complete data sets were analyzed from a sample of 50 consecutive patient records. After the program, there was a significant reduction in body perception disturbance (P < 0.0001), strength of negative emotional feelings (P < 0.0001), and pain (P = 0.0038). There was a significant correlation between a change in disturbance and pain (r = 0.44, P = 0.024). No relationship was found between the duration of symptoms and changes in disturbance (r = 0.04, P = 0.82). CONCLUSIONS: This study provides evidence that both body perception disturbance and pain reduce after rehabilitation. Findings suggest that targeting these disturbances may be important in reducing pain and may be a potentially useful measure for recovery. Controlled trials are required to confirm the effectiveness of rehabilitation and determine what factors are responsible for these reductions.

Living with joint hypermobility syndrome: patient experiences of diagnosis, referral and self-care.

BACKGROUND: Musculoskeletal problems are common reasons for seeking primary health care. It has been suggested that many people with 'everyday' non-inflammatory musculoskeletal problems may have undiagnosed joint hypermobility syndrome (JHS), a complex multi-systemic condition. JHS is characterized by joint laxity, pain, fatigue and a wide range of other symptoms. Physiotherapy is usually the preferred treatment option for JHS, although diagnosis can be difficult. The lived experience of those with JHS requires investigation. OBJECTIVE: The aim of the study was to examine patients' lived experience of JHS, their views and experiences of JHS diagnosis and management. METHODS: Focus groups in four locations in the UK were convened, involving 25 participants with a prior diagnosis of JHS. The focus groups were audio recorded, fully transcribed and analysed using the constant comparative method to inductively derive a thematic account of the data. RESULTS: Pain, fatigue, proprioception difficulties and repeated cycles of injury were among the most challenging features of living with JHS. Participants perceived a lack of awareness of JHS from health professionals and more widely in society and described how diagnosis and access to appropriate health-care services was often slow and convoluted. Education for patients and health professionals was considered to be essential. CONCLUSIONS: Timely diagnosis, raising awareness and access to health professionals who understand JHS may be particularly instrumental in helping to ameliorate symptoms and help patients to self-manage their condition. Physiotherapists and other health professionals should receive training to provide biopsychosocial support for people with this condition.

Joint hypermobility is a risk factor for musculoskeletal pain during adolescence: findings of a prospective cohort study.

OBJECTIVE: To determine whether joint hypermobility (JH) in childhood is a risk factor for the subsequent development of musculoskeletal pain. METHODS: JH was determined according to the Beighton score at age 13.8 years in children from the Avon Longitudinal Study of Parents and Children (ALSPAC), using a cutoff of ≥6 for the presence of hypermobility. Musculoskeletal pain was evaluated by questionnaire at age 17.8 years. Logistic regression analysis was performed in 2,901 participants (1,267 boys and 1,634 girls) who had complete data. RESULTS: A total of 4.6% of participants had JH at age 13.8 years. Moderately troublesome musculoskeletal pain at age 17.8 years was reported most commonly in the lower back (16.1%), shoulder (9.5%), upper back (8.9%), knee (8.8%), neck (8.6%), and ankle/foot (6.8%). JH was associated with an increased risk of at least moderately troublesome musculoskeletal pain at the shoulder (odds ratio [OR] 1.68 [95% confidence interval (95% CI) 1.04, 2.72]), knee (OR 1.83 [95% CI 1.10, 3.02]), and ankle/foot (OR 1.82 [95% CI 1.05, 3.16]) (adjusted for sex, maternal education, and body mass index). An equivalent relationship was not observed at other sites, including the spine, elbows, hands, and hips. In analyses examining interactions with obesity, associations between JH and knee pain showed higher ORs in obese participants (OR 11.01) as compared with nonobese participants (OR 1.57) (P=0.037 for the interaction of hypermobility and obesity). CONCLUSION: JH represents a risk factor for musculoskeletal pain during adolescence, comprising a specific distribution, namely, the shoulder, knee, and ankle/foot. These relationships were strongest in the presence of obesity, which is consistent with a causal pathway whereby JH leads to pain at sites exposed to the greatest mechanical forces.

Biomechanical changes in the gastrocnemius medius-Achilles tendon complex in people with hypermobility spectrum disorders: A cross-sectional compression sonoelastography study.

Objective: This study aimed to assess the biomechanical impact of Hypermobility Spectrum Disorders (HSD) on the elasticity of the gastrocnemius medius-Achilles tendon (GM-AT) complex. Methods: Using a cross-sectional design, the GM-AT complex elasticity was compared using sonoelastography (SEG) in an HSD group and healthy controls during rest and maximal isometric plantar flexion contraction. Results: The HSD group comprised 28 patients (26 women); mean ± SD age 28.7 ± 8.4 years, compared to 28 controls (26 women); 31.5 ± 8.7 years. During rest, greater elasticity was identified in HSD relative to controls at the GM-AT musculotendinous junction (strain ratio 2.05 ± 1.31 vs. 1.48 ± 0.49), mid-AT (3.60 ± 1.97 vs. 2.66 ± 1.00), and distal AT (4.57 ± 2.69 vs. 3.22 ± 1.94) (all p < 0.05). During contraction, no significant differences were found between groups at the GM-AT musculotendinous junction (3.40 ± 2.16 vs. 2.62 ± 1.07), mid AT (10.75 ± 5.29 vs. 8.49 ± 3.53), or distal AT (8.55 ± 5.39 vs. 8.83 ± 3.51) (all p > 0.05). No significant differences were found between groups in the GM strain ratio during rest (4.05 ± 1.43 vs. 3.62 ± 0.78), or contraction (4.23 ± 1.29 vs. 4.19 ± 1.31). Exploratory Receiver Operator Characteristics curve analysis suggested low sensitivity and specificity of the strain ratio for the diagnosis of HSD. Conclusion: People with HSD have greater GM-AT complex elasticity. Although statistically significant group differences were identified, further research is required to establish the diagnostic, clinical, and research utility of strain ratio measurements.

The concomitant diagnosis of fibromyalgia and connective tissue disorders: A systematic review.

BACKGROUND: Anecdotally, fibromyalgia syndrome (FMS) and connective tissue disorders (hypermobile Ehlers-Danlos Syndrome (hEDS), Hypermobility Spectrum disorders (HSD) and Generalized Joint Hypermobility (GJH)) manifest overlap in their diagnostic approach and symptomatic features. Understanding this overlap is important for accurate diagnosis and the success of subsequent management. This study therefore aimed to identify the prevalence of concomitant diagnosis of FMS and hEDS/HSD/GJH in adults and their shared symptomatic manifestations using a systematic review. METHODS: MEDLINE (via EBSCO host) was systematically searched. Observational research (case-control or single group) studies were considered for inclusion, where adults screened for hEDS/HSD/GJH and FMS were compared in terms of diagnostic prevalence, and musculoskeletal and non-musculoskeletal manifestations. Studies on pediatric populations were excluded. The quality of the included studies was assessed using the National Institute of Health Quality Assessment of Case-Control Studies and Jonna Briggs Critical Appraisal checklist for prevalence studies. The review was registered prospectively in PROSPERO (CRD42020216283). FINDINGS: The review included eleven studies: nine case-control studies and two single group studies. The prevalence of concomitant diagnosis of hEDS/HSD and FMS ranged from 68%-88.9% and from 8.0 to 64.2% for GJH and FMS. The prevalence and severity of a range of objective and patient-reported features were similar between hEDS/HSD and FMS, including joint pain (duration, persistence, SF-36-pain component score); joint swelling; muscle weakness; neurological problems; multidimensional pain inventory-activity; dysautonomia and total autonomic symptoms burden (including orthostatic intolerance, reflex syncope, vasomotor, gastrointestinal, diarrhea, constipation and pupillomotor domains); function; and quality of life. Shared symptomatic features between GJH and FMS were mean pain level, tender points count, total myalgia score and psychological impact. INTERPRETATION: There may be overlapping symptomatology and diagnostic prevalence of FMS and hEDS/HSD/GJH. Clinicians should consider both diagnoses to ensure appropriate diagnosis and management.

Arabic translation, cultural adaptation, and validation of the Bristol Impact of Hypermobility questionnaire.

BACKGROUND: The Bristol Impact of Hypermobility questionnaire (BIoH) is the first condition-specific patient reported outcome measure for people with hypermobility-related conditions. The BIoH original version is in English, which limits its use for patients who speak other languages. The study aimed to translate and culturally adapt the BIoH into Arabic and determine its concurrent validity, reliability, internal consistency and smallest detectable change. METHODS: Forward-backward translation and cross-sectional designs were used. The Ethics Committee of Kuwait Ministry of Health approved the study. Spearman correlation coefficient, intraclass correlation coefficient (ICC), and Cronbach's α were used for statistical analysis. Patients with hypermobility spectrum disorders (HSD) were included, diagnosed using the 2017 classification framework. RESULTS: 55 HSD patients were included, aged 26.0 (18.0) years old; median (IQR), and 85.5% were women. The BIoH showed very good concurrent validity when correlated with the SF-12 total and physical component scores; r = -0.743 and - 0.740, respectively (p < 0.05). Good correlation was identified between the BIoH and the SF-12 mental component score; r = -0.496 (p < 0.05). The BIoH demonstrated excellent test-retest reliability; ICC = 0.934 (0.749-0.983 95% CI) (p < 0.05), and high internal consistency (Cronbach's α = 0.933). The smallest detectable change was 30.90 points, representing 19.8% of the mean baseline score. CONCLUSIONS: The study successfully translated the BIoH into Arabic and demonstrated high psychometric properties. The translated score can help Arabic patients with HSD in their clinical evaluation process. Future research needs to determine the responsiveness of the Arabic version and translate the BIoH to other languages.

The value of dynamic elastomeric fabric orthoses in the management of a complex hypermobile Ehlers-Danlos syndrome patient: A case report.

The use of dynamic elastomeric fabric orthoses is examined in a young woman with hypermobile Ehlers-Danlos syndrome (hEDS) referred for physiotherapy with hip dysplasia, prior to a right periacetabular osteotomy. Dynamic elastomeric fabric orthoses plus rigorous subjective examination, therapists' listening skills, and patient-centered goals were useful for this hEDS patient.

A thematic exploration of patient and radiation therapist solutions to improve comfort during radiotherapy: A qualitative study.

PURPOSE: Patients undergoing radiotherapy are positioned to restrict motion, ensuring treatment accuracy. Immobilisation can be uncomfortable which may impact treatment accuracy. Therapeutic radiographers (TR) are responsible for managing patient comfort, yet there is little evidence to guide practice. The objective was to explore patient and RT experience of comfort management during radiotherapy and identify solutions for how comfort may be managed. MATERIALS AND METHODS: Twenty-five adult patients were purposefully recruited from Somerset NHS FT (SFT NHS) from those referred for, receiving or who had received radiotherapy within 3 months. Further criteria were that treatment delivery time on the couch exceeded 10 min (the time the patient was immobilised on the radiotherapy couch). 25 practicing TRs were recruited across the United Kingdom (UK) with experience of treatment delivery times exceeding 10 min. Semi structured interviews were conducted by the researcher at SFT NHS or in patients own homes and via telephone for TRs. Interviews were audio-recorded and transcribed verbatim. Thematic analysis was performed by SG and after familiarisation with data, generation of codes, the themes defined were reviewed by researchers and patient partners. FINDINGS: For patients, the three themes were: Supported Coping, Modification to Position or Immobilisation and Information Communication and Preparation. For TRs three main themes emerged: Supported Coping, Supporting and Adjusting Patients to Maintain Position and Preparational Approaches. CONCLUSION: This qualitative paper provided a shared voice of how comfort can be best managed from the perspective of patients and TRs. Patient and TR views of how comfort is best managed has provided solutions that may be used during radiotherapy. The study has highlighted some of the positive and negative experiences of comfort solutions based on current UK practice. This information will be used to develop recommendations in a radiotherapy comfort intervention package.

Patient and therapeutic radiographer experiences of comfort during the radiotherapy pathway: A qualitative study.

INTRODUCTION: There is little research regarding the experiences of patient comfort and how it is best managed in radiotherapy. The aim of this study was to explore the experiences of patient and therapeutic radiographer views of comfort during radiotherapy. METHODS: This qualitative study involved semi-structured interviews, with cancer patients (n = 25) and therapeutic radiographers (n = 25), conducted between January-July 2019. Patients were recruited from one radiotherapy clinic and therapeutic radiographers were recruited from across the United Kingdom via specialist interest groups and social media. Interviews were audio-recorded and transcribed verbatim. Thematic analysis was used to analyse the data separately between both groups and shared themes were identified. RESULTS: Four themes were identified of which two themes were shared among both the patients and therapeutic radiographer. Emotional Health was a shared theme highlighting experiences such as stress, vulnerability and privacy. The second shared theme, Positioning and Immobilisation Experiences, concerned how patients' experience being physically positioned and using immobilisation for accurate radiotherapy. The theme Information and Communication Experience was derived from patients highlighting concerns over sharing and provision of information and ways of communication. The last theme, Environmental Experience, emerged from the patient interviews and related to the first impressions of the radiotherapy environment such as reception or treatment rooms and how this effects the overall feelings of comfort. CONCLUSION: This qualitative study has provided the shared voice of patients and therapeutic radiographers and their experiences of comfort during radiotherapy. These shared experiences emphasise the importance of considering comfort holistically and not just from a physical context. This information can be used by therapeutic radiographers to better understand their patients experiences and needs to provide better comfort during radiotherapy to improve patients' outcomes. IMPLICATIONS FOR PRACTICE: The clinical implications of our study can encourage Therapeutic Radiographers to provide holistic care for their patients throughout the pathway and specifically to comfort patients while they are having treatment. In the short term this could be via simple adaptions to practice while in the long term, research is needed to develop comfort interventions for patients receiving radiotherapy.

Prehabilitation for frail patients undergoing total hip or knee replacement: protocol for the Joint PREP feasibility randomised controlled trial.

BACKGROUND: Approximately, 8% of community-based adults aged ≥ 50 years in England are frail. Frailty has been found to be associated with poorer outcomes after joint replacement. Targeting frailty preoperatively via exercise and protein supplementation has the potential to improve outcomes for people undergoing joint replacement. Prior to proceeding with a randomised controlled trial (RCT), a feasibility study is necessary to address key uncertainties and explore how to optimise trial design and delivery. METHODS: The Joint PRehabilitation with Exercise and Protein (Joint PREP) study is a feasibility study for a multicentre, two-arm, parallel group, pragmatic, RCT to evaluate the clinical and cost-effectiveness of prehabilitation for frail patients undergoing total hip or knee replacement. Sixty people who are ≥ 65 years of age, frail according to the self-reported Groningen Frailty Indicator, and scheduled to undergo total hip or knee replacement at 2-3 hospitals in England and Wales will be recruited and randomly allocated on a 1:1 ratio to the intervention or usual care group. The usual care group will receive the standard care at their hospital. The intervention group will be given a daily protein supplement and will be asked to follow a home-based, tailored daily exercise programme for 12 weeks before their operation, in addition to usual care. Participants will be supported through six follow-up calls from a physiotherapist during the 12-week intervention period. Study questionnaires will be administered at baseline and 12 weeks after randomisation. Embedded qualitative research with patients will explore their experiences of participating, reasons for nonparticipation, and/or reasons for withdrawal or treatment discontinuation. Primary feasibility outcomes will be eligibility and recruitment rates, adherence to the intervention, and acceptability of the trial and the intervention. DISCUSSION: This study will generate important data regarding the feasibility of a RCT to evaluate a prehabilitation intervention for frail patients undergoing total hip and knee replacement. A future phase-3 RCT will determine if preoperative exercise and protein supplementation improve the recovery of frail patients after primary joint replacement. TRIAL REGISTRATION: ISRCTN11121506, registered 29 September 2022.

Somatosensory abnormalities in knee OA.

OBJECTIVE: The aim of this study was to use quantitative sensory testing (QST) to explore the range and prevalence of somatosensory abnormalities demonstrated by patients with advanced knee OA. METHODS: One hundred and seven knee OA patients and 50 age- and sex-matched healthy participants attended a 1-h QST session. Testing was performed on the medial side of the knee and the pain-free forearm. Light-touch thresholds were assessed using von Frey filaments, pressure pain thresholds using a digital pressure algometer, and thermal sensation and pain thresholds using a Thermotest MSA. Significant differences in median threshold values from knee OA patients and healthy participants were identified using Mann-Whitney U-tests. The z-score transformations were used to determine the prevalence of the different somatosensory abnormalities in knee OA patients. RESULTS: Testing identified 70% of knee OA patients as having at least one somatosensory abnormality. Comparison of median threshold values between knee OA patients and healthy participants revealed that patients had localized thermal and tactile hypoaesthesia and pressure hyperalgesia at the osteoarthritic knee. Tactile hypoaesthesia and pressure hyperalgesia were also present at the pain-free forearm. The most prevalent somatosensory abnormalities were tactile hypoaesthesia and pressure hyperalgesia, evident in between 20 and 34% of patients. CONCLUSION: This study found that OA patients demonstrate an array of somatosensory abnormalities, of which the most prevalent were tactile hypoaesthesia and pressure hyperalgesia. Further research is now needed to establish the clinical implications of these somatosensory abnormalities.

Epidemiology of generalized joint laxity (hypermobility) in fourteen-year-old children from the UK: a population-based evaluation.

OBJECTIVE: Although diagnostic criteria for generalized ligamentous laxity (hypermobility) in children are widely used, their validity may be limited, due to the lack of robust descriptive epidemiologic data on this condition. The present study was undertaken to describe the point prevalence and pattern of hypermobility in 14-year-old children from a population-based cohort. METHODS: We performed a cross-sectional analysis using the Avon Longitudinal Study of Parents and Children, a large population-based birth cohort. Hypermobility among children in the cohort (mean age 13.8 years) was measured using the Beighton scoring system. Objective measures of physical activity were ascertained by accelerometry. Data on other variables, including puberty and socioeconomic status, were collected. Simple prevalence rates were calculated. Chi-square tests and logistic regression analyses were used to assess associations of specific variables with hypermobility. RESULTS: Among the 6,022 children evaluated, the prevalence of hypermobility (defined as a Beighton score of ≥4 [i.e., ≥4 joints affected]) in girls and boys age 13.8 years was 27.5% and 10.6%, respectively. Forty-five percent of girls and 29% of boys had hypermobile fingers. There was a suggestion of a positive association between hypermobility in girls and variables including physical activity, body mass index, and maternal education. No associations were seen in boys. CONCLUSION: We have shown that the prevalence of hypermobility in UK children is high, possibly suggesting that the Beighton score cutoff of ≥4 is too low or that this scoring is not appropriate for use in subjects whose musculoskeletal system is still developing. These results provide a platform to evaluate the relationships between the Beighton criteria and key clinical features (including pain), thereby testing the clinical validity of this scoring system in the pediatric population.

The effect of stimulus number on the stability of responses for an extensive heat pain test.

BACKGROUND: The use of relatively lower stimulus presentation numbers in quantitative sensory testing may influence the computation accuracy of participants' discriminability. The minimum trial number for obtaining a stabilized participant discrimination ability was determined. MATERIALS AND METHODS: Twelve participants' ability to discriminate between noxious heat stimuli pairs (45°C/46°C, 46°C/47°C, and 47°C/48°C) was assessed using a six-category confidence rating scale. Heat stimuli were administered to the forearm. Two conditions with presentation numbers of 17 trials per stimulus (representing the median number of trials in previous studies) and 40 trials per stimulus (used in a previous study with a similar protocol) were used. RESULTS AND DISCUSSION: Participants' discriminability stabilized at approximately the 20th trial based on the lowest frequency of indeterminate and non-model conforming results under both conditions. A simple linear regression model showed a statistically significant positive relationship between discriminability for the two conditions (slope = 0.65, p < 0.001; constant = 0.33, p = 0.02; r(2 )= 0.51). As a rule of thumb, approximately 20 trials per stimulus intensity could be used to obtain a stabilized discriminability outcome.

Pain intensity and quality of life perception in children with hypermobility syndrome.

Hypermobility syndrome (HMS) is a major source of morbidity in children. Impaired quality of life (QoL) has been observed recently in adults with HMS; however, this issue is yet to be investigated in children with this condition. This study compared pain intensity and QoL in children with HMS with healthy controls. It also examined the relationship between pain intensity and QoL in children with HMS. Following ethical approval, 29 children diagnosed with HMS and 37 healthy children aged 8-15 years participated. Informed written consent was obtained from participants and their parents/guardians. Average knee pain over the past week was examined using the Coloured Analogue Scale. QoL was measured via the Pediatric Quality of Life Inventory. Mann-Whitney U tests were performed to compare pain and QoL scores between the two groups. Spearman Rho correlation analysis was performed to examine the relationship between pain and QoL. Overall QoL scores in each domain were significantly lower in children with HMS (all p < 0.001) compared with the controls. Pain intensity was significantly higher in children with HMS compared with their healthy counterparts (p < 0.001). A strong negative correlation was observed between pain intensity and overall QoL and all the domains (r range = -0.614 to -0.717; all p < 0.001). In conclusion, the findings of the present study imply that pain and QoL assessment might form important components of clinical examination for children diagnosed with HMS. These children may benefit from appropriate treatment programmes to alleviate pain intensity and improve QoL.
