Abstract
Facioscapulohumeral muscular dystrophy (FSHD) is a common form of adult muscular dystrophy often resulting also in cardiorespiratory deconditioning and weakness of the lower limbs. Although previous studies examined outcomes of interventions aimed at improving either cardiorespiratory fitness or muscle strength, the potential benefits of a rehabilitation program targeting both remain unexplored. Thus, the aim of this study was to evaluate changes following participation in a rehabilitation program combining aerobic and strength exercises. We conducted a retrospective analysis of 10 subjects with FSHD who participated in our rehabilitation program during 2018 and 2019. Each of the 20 sessions consisted of aerobic training on a cycloergometer and a moderate lower limb strength exercises on an isokinetic machine in combination with conventional therapy. The primary outcomes were walking speed, aerobic performance and isokinetic strength of the knee extensors and flexors. The secondary outcomes were fatigue, insomnia. VO2max and walking speed increased significantly by 2.125 ml·kg-1·min-1 [95% confidence interval (CI): 0.75-3.62, P = 0.022] and 0.28 m/s (95% CI: 0.16-0.4, P = 0.002), respectively. The effect size was small for V02max (Hedge's g, 0.44; 95% CI: -0.5 to 1.37) and large for walking speed (Hedge's g, 0.99; 95% CI: 0.06-1.92). The knee flexor strength significantly increased at rehabilitation discharge (repeated measures analysis of variance P = 0.004). Positive changes in fatigue and insomnia were also observed. Our preliminary results provide evidence that a relatively short course of a comprehensive rehabilitation program targeting both cardiorespiratory fitness and knee muscle strength can be beneficial for people with FSHD, which warrants further prospective studies.

Abstract
This study's objective is to understand the effect of muscular weakness in persons with facioscapulohumeral dystrophy as well as the effect of a dynamic arm support on muscle coordination and activity performance, during activities of daily living. People with facioscapulohumeral dystrophy (n=12, 56.0±14.5 years) and healthy controls (n=12, 55.5±13.4 years) performed five simulated daily activity tasks, while unsupported and supported by the Gowing dynamic arm support. Surface electromyography, kinematics, and maximum force output were recorded. Outcomes were calculated for muscle coordination (muscle synergies), maximum muscle activity, movement performance indicators, and upper limb muscular weakness (maximum force output). Muscle coordination was altered and less consistent in persons with facioscapulohumeral dystrophy compared with healthy controls. The dynamic arm support alleviated muscle efforts and affected muscle coordination in both populations. While populations became more similar, the internal consistency of persons with facioscapulohumeral dystrophy remained unaffected and lower than that of healthy controls. Furthermore, the support affected movements' performance in both groups. The maximum force outputs were lower in persons with facioscapulohumeral dystrophy than controls. Muscle coordination differences were presumably the result of individual-specific in muscle weakness and compensatory strategies for dealing with gravity compensation and movement constraints.

Abstract
Facioscapulohumeral muscular dystrophy (FSHD) is an exclusively human neuromuscular disease. In the last decades the cause of FSHD was identified: the loss of epigenetic repression of the D4Z4 repeat on chromosome 4q35 resulting in inappropriate transcription of DUX4. This is a consequence of a reduction of the array below 11 units (FSHD1) or of a mutation in methylating enzymes (FSHD2). Both require the presence of a 4qA allele and a specific centromeric SSLP haplotype. Muscles become involved in a rostro-caudally order with an extremely variable progression rate. Mild disease and non-penetrance in families with affected individuals is common. Furthermore, 2% of the Caucasian population carries the pathological haplotype without clinical features of FSHD.In order to explain the various features of FSHD we applied Ockham's Razor to all possible scenarios and removed unnecessary complexities. We postulate that early in embryogenesis a few cells escape epigenetic silencing of the D4Z4 repeat. Their number is assumed to be roughly inversely related to the residual D4Z4 repeat size. By asymmetric cell division, they produce a rostro-caudal and medio-lateral decreasing gradient of weakly D4Z4-repressed mesenchymal stem cells. The gradient tapers towards an end as each cell-division allows renewed epigenetic silencing. Over time, this spatial gradient translates into a temporal gradient based on a decreasing number of weakly silenced stem cells. These cells contribute to a mildly abnormal myofibrillar structure of the fetal muscles. They also form a downward tapering gradient of epigenetically weakly repressed satellite cells. When activated by mechanical trauma, these satellite cells de-differentiate and express DUX4. When fused to myofibrils they contribute to muscle cell death in various ways. Over time and dependent on how far the gradient reaches the FSHD phenotype becomes progressively manifest. We thus hypothesize FSHD to be a myodevelopmental disease with a lifelong attempt to restore DUX4 repression.

Abstract
For patients affected by Facioscapulohumeral dystrophy (FSHD), alternate methods for increasing physical activity engagement that may benefit shoulder function and wider health are needed. Arm cycling has been proposed as a potential method for achieving this although dosage parameters and evidence is limited. The aim of this study was to conduct a pilot study evaluating the effect of a single intermittent arm cycling exercise programme on people affected by FSHD. People with confirmed genetic diagnosis of FSHD between the ages 18-60 years were recruited to attend a single session for the exercise intervention (5 exercise efforts lasting 2 minutes each with 30 seconds of rest between each effort). Prior to exercise, measures of shoulder function (Oxford shoulder score), strength and range of movement were recorded. During the exercise participants were video recorded to quantify range of movement and extract movement profile features. Participants comments were recorded and followed up four days later to check for adverse events. Fifteen participants, (6F:9M) were recruited with median (IQR) Oxford Shoulder Scores of 25 (18 to 39). All participants successfully completed the exercise intervention with only transient symptoms consistent with exercise being reported and achieving a median (IQR) rate of perceived exertion scores of 13 (12 to 13). Movement profile data was available for 12 out of 15 participants and suggests that exercise intensity did not compromise movement. An association between strength and shoulder function (R2 = 0.5147), Rate of perceived exertion (RPE) of the final effort against shoulder function and strength (R2 = 0.2344 and 0.1743 respectively) was identified. Participant comments were positive regarding the exercise intervention. Our study demonstrates that an intermittent arm cycling programme is feasible for people affected by FSHD. Further work is needed to evaluate physiological responses to exercise across variations in programme variables and equipment set up in a larger sample of people affected by FSHD.

Abstract
More than 80% of patients with facioscapulohumeral muscular dystrophy (FSHD) report shoulder instability that affects daily life. Despite this, only 44.4% engaged with exercises that target the upper body. There is a lack of evidence to inform upper limb FSHD rehabilitation exercises. Patients with FSHD support the need for further research in upper limb exercises.
Objective To identify (1) what exercise modalities people living with facioscapulohumeral muscular dystrophy (FSHD) are undertaking in the community as a part of their ongoing rehabilitation and (2) what future research projects would gain the support of people with FSHD. Design An online questionnaire composed of open and closed questions. Conventional content analysis was used for open questions, and quantitative analysis was used for closed questions. Setting Online questionnaire distributed to a United Kingdom FSHD registry. Participants A total of 232 patients on the United Kingdom FSHD registry (N=232). Interventions None. Main Outcome Measures None. Results A response rate of 43.6% was achieved with 232 of 532 patients completing the survey. Despite 85.8% (n=199) of patients experiencing shoulder instability that affects daily living, only 44.4% (n=103) engaged with exercises targeting the upper body. The themes from the data were understanding of disease mechanism shaping exercise choice, lack of understanding about the condition and the benefit of exercise, support from professionals, barriers to exercise, and thoughts about future research. Participants (92.2%, n=214) agreed additional research into upper limb exercises is needed and felt a 3-month arm cycling intervention with monthly clinical visits and magnetic resonance imaging would be appropriate. Conclusions Exercise selection was variable among patients with FSHD, and lack of information, pain, fatigue, availability and access to facilities, cost, and time were identified as barriers to exercise. This may account for the limited engagement with upper limb rehabilitation despite the high percentage of shoulder instability in patients with FSHD. Further research is needed to develop evidence-based exercise interventions, and guidance for upper limb exercise prescription in FSHD, and patients are supportive of this.

Scapular Winging following Sports-Related Injury in a Rugby Player. Case Rep Orthop 2021; 2021:4511538.

Abstract
The most common cause of medial scapular winging is long thoracic nerve palsy (LTN) and subsequent serratus anterior muscle dysfunction. A 16-year-old right-handed male high-school rugby player developed severe right-sided neck and shoulder pain after tackling an opponent while playing rugby. Six weeks after initial injury, the patient observed shoulder muscle weakness when performing his daily activities. On physical examination, limited active elevation of the right shoulder in the scapular plane and scapular winging was observed. Magnetic resonance imaging revealed atrophy of both the SA and subclavius muscles on the right side, and we initially suspected an LTN injury sustained. However, while detailing his history, the patient explained that he also had noted difficulty sucking high viscosity drinks such as shakes and smoothies since childhood. In addition, physical examination showed weakness of the orbicularis oculi muscle. Considering the facial muscle weakness, facioscapulohumeral dystrophy (FSHD) was also suspected, and genetic testing showed chromosome 4q35 deletion with restriction fragments 17 kb and 3 tandem repeated DNA confirming the diagnosis of FSHD. Clinicians should be aware that FSHD could be one of the differential diagnoses of scapular winging after sports injury, and surgeons should rule out the diagnosis of FSHD before performing any surgical treatment for SA palsy.

Abstract
PURPOSE Neuromuscular disorders are characterised by muscle weakness that limits upper extremity mobility, but can be alleviated with dynamic arm support devices. Current research highlights the importance and difficulties of evidence-based recommendations for device development. We aim to provide research recommendations primarily concerning upper extremity body functions, and secondarily activity and participation, environmental and personal factors. METHODS Evidence was synthesised from literature, ongoing studies, and expert opinions and tabulated within a framework based on a combination of the International Classification of Functioning, Disability and Health (ICF) model and contextual constructs. RESULTS Current literature mostly investigated the motor capacity of muscle function, joint mobility, and upper body functionality, and a few studies also addressed the impact on activity and participation. In addition, experts considered knowledge on device utilisation in the daily environment and characterising the beneficiaries better as important. Knowledge gaps showed that ICF model components and contextual constructs should be better integrated and more actively included in future research. CONCLUSIONS It is recommended to, first, integrate multiple ICF model components and contextual constructs within one study design. Second, include the influence of environmental and personal factors when developing and deploying a device. Third, include short-term and long-term measurements to monitor adaptations over time. Finally, include user satisfaction as guidance to evaluate the device effectiveness.IMPLICATIONS ON REHABILITATIONSynthesized evidence will support future research and development of dynamic arm supports.Tabulated evidence stresses the importance of integrating ICF model components and contextual constructs to fill the knowledge gaps.Presented knowledge gaps and proposed steps guide the set up of future studies on dynamic arm supports.

Abstract
Facioscapulohumeral dystrophy (FSHD) is a progressive muscle-wasting disease which leads to a decline in upper extremity functionality. Although the scapulohumeral joint's stability and functionality are affected, evidence on the synergetic control of the shoulder muscles in FSHD individuals is still lacking. The aim of this paper is to understand the neuromuscular changes in shoulder muscle control in people with FSHD. Upper arm kinematics and electromyograms (EMG) of eight upper extremity muscles were recorded during shoulder abduction-adduction and flexion-extension tasks in eleven participants with FSHD and 11 healthy participants. Normalized muscle activities were extracted from EMG signals. Non-negative matrix factorization was used to compute muscle synergies. Maximum muscle activities were compared using non-parametric analysis of variance. Similarities between synergies were also calculated using correlation. The Biceps Brachii was significantly more active in the FSHD group (25±2%) while Trapezius Ascendens and Serratus Anterior were less active (32±7% and 39±4%, respectively). Muscle synergy weights were altered in FSHD individuals and showed greater diversity while controls mostly used one synergy for both tasks. The decreased activity by selected scapula rotator muscles and muscle synergy weight alterations show that neuromuscular control of the scapulohumeral joint is less consistent in people with FSHD compared to healthy participants. Assessments of muscle coordination strategies can be used to evaluate motor output variability and assist in management of the disease.

Abstract
OBJECTIVE An observational cross-sectional study was conducted in a national facioscapulohumeral muscular dystrophy (FSHD) expertise center to estimate the penetrance of FSHD1 and to evaluate phenotype-genotype correlations. METHODS Ten FSHD1 probands carrying 4-9 D4Z4 unit alleles and 140 relatives were examined. All 150 participants were genetically characterized, including D4Z4 methylation levels in the mutation carriers. Mutation carriers were classified as (1) symptomatic: with symptoms of muscle weakness on history and muscle FSHD signs on examination; (2) asymptomatic: without symptoms of muscle weakness but with muscle FSHD signs on examination; and (3) nonpenetrant: without symptoms of muscle weakness on history and without muscle FSHD signs on examination. We assessed the relationship between age-corrected clinical severity score and repeat size, sex, and D4Z4 methylation levels. RESULTS The maximum likelihood estimates of symptomatic and those of symptomatic plus asymptomatic FSHD showed that penetrance depends on repeat size and increases until late adulthood. We observed many asymptomatic carriers with subtle facial weakness with or without mild shoulder girdle weakness (25% [17/69]). Nonpenetrance was observed less frequently than in recent population studies (17% [12/69]), and most asymptomatic patients reported some shoulder pain. D4Z4 methylation tended to be lower in moderately to severely affected mutation carriers with 7 or 9 repeats. DISCUSSION This family-based study detected a lower overall nonpenetrance than previously observed, probably due to many asymptomatic mutation carriers identified by careful examination of facial and shoulder muscles. The recognition of asymptomatic mutation carriers is essential for selection of participants for future trials, and the likelihood estimates are helpful in counseling.
