Inspiratory muscle training in neuromuscular patients: Assessing the benefits of a novel protocol.

BACKGROUND: Neuromuscular diseases are characterized by the compromise of respiratory muscles, thoracic ventilation, muscle strength and coughing capacity. Patients have low quality of life and increased morbidity and mortality mostly due to respiratory impairment. OBJECTIVE: To assess the benefits of adding inspiratory muscle training to neuromuscular patients' treatment and their compliance to the approach. METHODS: We conducted a single-center prospective study with neuromuscular patients with decreased maximal inspiratory pressure. We developed an inspiratory muscle training protocol with three-month duration and once-daily training. The protocol had a progressive intensity that was individually tailored based on patients' baseline characteristics and tolerance. We used Powerbreathe Medic Classic devices to perform the training. RESULTS: There were 21 patients who met the inclusion criteria and were enrolled in the study. Muscular dystrophy (n= 12, 57.3%) and amyotrophic lateral sclerosis (n= 4, 19%) were the most common diseases. After three months of training, patients increased their maximal inspiratory muscle pressure (p= 0.002) and peak cough flow (p= 0.011). Compliance to the protocol was 99 ± 5.5%. CONCLUSIONS: This protocol showed significant improvements on pulmonary muscles function and might be considered as an adjunct treatment to neuromuscular treatment. However, these positive results require larger further studies to validate the clinical benefits long-term.

User-centred assistive SystEm for arm Functions in neUromuscuLar subjects (USEFUL): a randomized controlled study.

BACKGROUND: Upper limb assistive devices can compensate for muscular weakness and empower the user in the execution of daily activities. Multiple devices have been recently proposed but there is still a lack in the scientific comparison of their efficacy. METHODS: We conducted a cross-over multi-centric randomized controlled trial to assess the functional improvement at the upper limb level of two arms supports on 36 patients with muscular dystrophy. Participants tested a passive device (i.e., Wrex by Jaeco) and a semi-active solution for gravity compensation (i.e., Armon Ayura). We evaluated devices' effectiveness with an externally-assessed scale (i.e., Performance of the Upper Limb-PUL-module), a self-perceived scale (i.e., Abilhand questionnaire), and a usability scale (i.e., System Usability Scale). Friedman's test was used to assess significant functional gain for PUL module and Abilhand questionnaire. Moreover, PUL changes were compared by means of the Friedman's test. RESULTS: Most of the patients improved upper limb function with the use of arm supports (median PUL scores increase of 1-3 points). However, the effectiveness of each device was related to the level of residual ability of the end-user. Slightly impaired patients maintained the same independence without and with assistive devices, even if they reported reduced muscular fatigue for both devices. Moderately impaired patients enhanced their arm functionality with both devices, and they obtained higher improvements with the semi-active one (median PUL scores increase of 9 points). Finally, severely impaired subjects benefited only from the semi-active device (median PUL scores increase of 12 points). Inadequate strength was recognized as a barrier to passive devices. The usability, measured by the System Usability Scale, was evaluated by end-users "good" (70/100 points) for the passive, and "excellent" (80/100 points) for the semi-active device. CONCLUSIONS: This study demonstrated that assistive devices can improve the quality of life of people suffering from muscular dystrophy. The use of passive devices, despite being low cost and easy to use, shows limitations in the efficacy of the assistance to daily tasks, limiting the assistance to a predefined horizontal plane. The addition of one active degree of freedom improves efficacy and usability especially for medium to severe patients. Further investigations are needed to increase the evidence on the effect of arm supports on quality of life and diseases' progression in subjects with degenerative disorders. Trial registration clinicaltrials.gov, NCT03127241, Registered 25th April 2017. The clinical trial was also registered as a post-market study at the Italian Ministry of Health.

Responsiveness and Minimal Clinically Important Difference of the Motor Function Measure in Collagen VI-Related Dystrophies and Laminin Alpha2-Related Muscular Dystrophy.

OBJECTIVES: To investigate the responsiveness of the motor function measure (MFM) and determine the minimal clinically important difference (MCID) in individuals with 2 common types of congenital muscular dystrophy (CMD). DESIGN: Observational, prospective, single center, cohort study. SETTING: National Institute of Neurological Disorders and Stroke (NINDS) of the National Institutes of Health (NIH). PARTICIPANTS: Individuals (N=44) with collagen VI-related dystrophies (COL6-RD, n=23) and 21 individuals laminin alpha2-related muscular dystrophy (LAMA2-RD, n=21) enrolled in a 4-year longitudinal natural history study. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Responsiveness of the MFM-32 and the Rasch-scaled MFM-25 and the MCID of the MFM-32 determined from a patient-reported anchor with 2 different methods, within-patient and between-patient. RESULTS: The original MFM-32 and Rasch-scaled MFM-25 performed similarly overall in both the COL6-RD and LAMA2-RD populations, with all subscores (D1, standing and transfers; D2, axial and proximal; D3, distal) showing a significant decrease over time, except MFM D1 and D3 for LAMA2-RD. The MFM D1 subscore was the most sensitive to change for ambulant individuals, whereas the MFM D2 subscore was the most sensitive to change for nonambulant individuals. The MCID for the MFM-32 total score was calculated as 2.5 and 3.9 percentage points according to 2 different methods. CONCLUSIONS: The MFM showed strong responsiveness in individuals with LAMA2-RD and COL6-RD. Because a floor effect was identified more prominently with the Rasch-Scaled MFM-25, the use of the original MFM-32 as a quantitative variable with the assumption of scale linearity appears to be a good compromise. When designing clinical trials in congenital muscular dystrophies, the use of MCID for MFM should be considered to determine if a given intervention effects show not only a statistically significant change but also a clinically meaningful change.

Inappropriate/d bodies: Reorganizing the terms of life and death.

The aim of this article is to offer insight into the different meanings of death that pierce the lives of people with disabilities and to discuss how those meanings are formed through a close connection with their bodies. To do that, I take an anthropological approach to trace the life paths of two individuals from a southern Latin American metropolis, exploring their embodied experiences of disability. Based on their accounts, I look at how their bodies are affected by specific conditions of stigma, dispossession, and social death, but also how, as "inappropriate/d" bodies, they rise above the logic of difference and move from a state of "absence" to a state of "presence" in the social world.

ABSTRACT The aim of this study is to map the use of aquatic physical therapy in individuals with muscular dystrophy, to characterize aquatic physical therapy intervention and identify measured components (variables and measurement instruments used) by the studies. A systematic scoping review included experimental, descriptive and observational studies (in English, Portuguese and Spanish languages). The searches were carried out on MEDLINE (PubMed), CINAHL, Embase, PEDro, Lilacs, ERIC, Scopus, Web of Science, Google Scholar. The extracted data were characterized into three categories: (1) characterization of the records, (2) information referring to aquatic physical therapy, and (3) measured components. There were 556 studies records and 20 records were selected. The studies samples included mostly individuals with Duchenne muscular dystrophy, aged between 5 and 22 years old. Aquatic physical therapy sessions lasted about 45 minutes, and one or two sessions per week were carried out for 21 weeks. That corroborates studies conducted in different populations. Most of the studies investigated pulmonary system and postural control/ functional ability, and a few studies evaluated cardiac system. Egen Klassifikation and North Star Ambulatory Assessment are recommended, and also to perform 6-minute walk test.

Strength training and aerobic exercise training for muscle disease.

BACKGROUND: Strength training or aerobic exercise programmes, or both, might optimise muscle and cardiorespiratory function and prevent additional disuse atrophy and deconditioning in people with a muscle disease. This is an update of a review first published in 2004 and last updated in 2013. We undertook an update to incorporate new evidence in this active area of research. OBJECTIVES: To assess the effects (benefits and harms) of strength training and aerobic exercise training in people with a muscle disease. SEARCH METHODS: We searched Cochrane Neuromuscular's Specialised Register, CENTRAL, MEDLINE, Embase, and CINAHL in November 2018 and clinical trials registries in December 2018. SELECTION CRITERIA: Randomised controlled trials (RCTs), quasi-RCTs or cross-over RCTs comparing strength or aerobic exercise training, or both lasting at least six weeks, to no training in people with a well-described muscle disease diagnosis. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. MAIN RESULTS: We included 14 trials of aerobic exercise, strength training, or both, with an exercise duration of eight to 52 weeks, which included 428 participants with facioscapulohumeral muscular dystrophy (FSHD), dermatomyositis, polymyositis, mitochondrial myopathy, Duchenne muscular dystrophy (DMD), or myotonic dystrophy. Risk of bias was variable, as blinding of participants was not possible, some trials did not blind outcome assessors, and some did not use an intention-to-treat analysis. Strength training compared to no training (3 trials) For participants with FSHD (35 participants), there was low-certainty evidence of little or no effect on dynamic strength of elbow flexors (MD 1.2 kgF, 95% CI -0.2 to 2.6), on isometric strength of elbow flexors (MD 0.5 kgF, 95% CI -0.7 to 1.8), and ankle dorsiflexors (MD 0.4 kgF, 95% CI -2.4 to 3.2), and on dynamic strength of ankle dorsiflexors (MD -0.4 kgF, 95% CI -2.3 to 1.4). For participants with myotonic dystrophy type 1 (35 participants), there was very low-certainty evidence of a slight improvement in isometric wrist extensor strength (MD 8.0 N, 95% CI 0.7 to 15.3) and of little or no effect on hand grip force (MD 6.0 N, 95% CI -6.7 to 18.7), pinch grip force (MD 1.0 N, 95% CI -3.3 to 5.3) and isometric wrist flexor force (MD 7.0 N, 95% CI -3.4 to 17.4). Aerobic exercise training compared to no training (5 trials) For participants with DMD there was very low-certainty evidence regarding the number of leg revolutions (MD 14.0, 95% CI -89.0 to 117.0; 23 participants) or arm revolutions (MD 34.8, 95% CI -68.2 to 137.8; 23 participants), during an assisted six-minute cycle test, and very low-certainty evidence regarding muscle strength (MD 1.7, 95% CI -1.9 to 5.3; 15 participants). For participants with FSHD, there was low-certainty evidence of improvement in aerobic capacity (MD 1.1 L/min, 95% CI 0.4 to 1.8, 38 participants) and of little or no effect on knee extension strength (MD 0.1 kg, 95% CI -0.7 to 0.9, 52 participants). For participants with dermatomyositis and polymyositis (14 participants), there was very low-certainty evidence regarding aerobic capacity (MD 14.6, 95% CI -1.0 to 30.2). Combined aerobic exercise and strength training compared to no training (6 trials) For participants with juvenile dermatomyositis (26 participants) there was low-certainty evidence of an improvement in knee extensor strength on the right (MD 36.0 N, 95% CI 25.0 to 47.1) and left (MD 17 N 95% CI 0.5 to 33.5), but low-certainty evidence of little or no effect on maximum force of hip flexors on the right (MD -9.0 N, 95% CI -22.4 to 4.4) or left (MD 6.0 N, 95% CI -6.6 to 18.6). This trial also provided low-certainty evidence of a slight decrease of aerobic capacity (MD -1.2 min, 95% CI -1.6 to 0.9). For participants with dermatomyositis and polymyositis (21 participants), we found very low-certainty evidence for slight increases in muscle strength as measured by dynamic strength of knee extensors on the right (MD 2.5 kg, 95% CI 1.8 to 3.3) and on the left (MD 2.7 kg, 95% CI 2.0 to 3.4) and no clear effect in isometric muscle strength of eight different muscles (MD 1.0, 95% CI -1.1 to 3.1). There was very low-certainty evidence that there may be an increase in aerobic capacity, as measured with time to exhaustion in an incremental cycle test (17.5 min, 95% CI 8.0 to 27.0) and power performed at VO2 max (maximal oxygen uptake) (18 W, 95% CI 15.0 to 21.0). For participants with mitochondrial myopathy (18 participants), we found very low-certainty evidence regarding shoulder muscle (MD -5.0 kg, 95% CI -14.7 to 4.7), pectoralis major muscle (MD 6.4 kg, 95% CI -2.9 to 15.7), and anterior arm muscle strength (MD 7.3 kg, 95% CI -2.9 to 17.5). We found very low-certainty evidence regarding aerobic capacity, as measured with mean time cycled (MD 23.7 min, 95% CI 2.6 to 44.8) and mean distance cycled until exhaustion (MD 9.7 km, 95% CI 1.5 to 17.9). One trial in myotonic dystrophy type 1 (35 participants) did not provide data on muscle strength or aerobic capacity following combined training. In this trial, muscle strength deteriorated in one person and one person had worse daytime sleepiness (very low-certainty evidence). For participants with FSHD (16 participants), we found very low-certainty evidence regarding muscle strength, aerobic capacity and VO2 peak; the results were very imprecise. Most trials reported no adverse events other than muscle soreness or joint complaints (low- to very low-certainty evidence). AUTHORS' CONCLUSIONS: The evidence regarding strength training and aerobic exercise interventions remains uncertain. Evidence suggests that strength training alone may have little or no effect, and that aerobic exercise training alone may lead to a possible improvement in aerobic capacity, but only for participants with FSHD. For combined aerobic exercise and strength training, there may be slight increases in muscle strength and aerobic capacity for people with dermatomyositis and polymyositis, and a slight decrease in aerobic capacity and increase in muscle strength for people with juvenile dermatomyositis. More research with robust methodology and greater numbers of participants is still required.

Residential immersive life skills programs for youth with disabilities: a case study of youth developmental trajectories of personal growth and caregiver perspectives.

BACKGROUND: Professional support in pediatric and rehabilitation care environments has been recommended as a means to build youth competence in life skills during their transition to adulthood. Life skills are the essential psychosocial competencies and interpersonal skills needed to manage one's life. Residential immersive life skills (RILS) programs offer youth with physical disabilities enriched learning environments to acquire these skills. This study explored trajectories of personal growth in life skills and positive psychological outcomes among youth participating in a RILS program and related caregiver perspectives. METHOD: Delivered by a multidisciplinary healthcare team, The Independence Program is an intensive summer program housed in a college residence that provides realistic experiences of living away from home for small groups of youth between 17 and 21 years of age who have congenital and/or acquired physical disabilities. Using a longitudinal case study and qualitative descriptive design, four youth and their parents/guardians participated in semi-structured interviews prior to, and then 1 month, and 3 to 4 months after the program. A conventional content analysis yielded chronological narratives for each youth and caregiver dyad of their experiences, perceptions and outcomes over time. These narratives were further summarized using a 'line of development' perspective to describe individual developmental trajectories of personal growth. RESULTS: All four of the youth returned from the program with positive reports about the new life skills acquired and new behaviours they engaged in. These positive reports generally continued post-program, albeit with differing trajectories unique to each youth and varying levels of congruence with their caregivers' readiness to support, accommodate and facilitate these changes. Caregivers differed in their capacity to shift in their parenting role to support consolidation of youth life skill competencies following program participation. CONCLUSIONS: RILS programs can be transformative. Varied youth trajectories identified significant personal growth through enhanced self-determination, self-efficacy and self-advocacy. Congruence in youth and caregiver perceptions of post-program changes was an important transactional factor. Professional support addressing caregiver needs may be beneficial to facilitate developmentally appropriate shifts in parenting roles. This shift is central to a model of shared management whereby adolescents take on greater responsibility for their own care and life choices.

Moderate-intensity aerobic exercise improves physical fitness in bethlem myopathy.

INTRODUCTION: Bethlem myopathy is caused by dysfunctional collagen VI assembly, leading to varying degrees of hyperlaxity, contractures and muscle weakness. Previous studies demonstrate that cardiovascular training is safe and beneficial in patients with myopathies. However, exercise exacerbates the dystrophic phenotype in collagen VI-knockout mice. METHODS: Six men with Bethlem myopathy were included (4 training; 2 controls). After training, 2 patients detrained. Patients performed 10 weeks of home-based, moderate-intensity exercise monitored by a pulse-watch. The primary outcome was change in peak oxygen uptake (VO2peak ). Secondary outcomes were performances in functional tests. RESULTS: VO2peak improved in the training group (16%, P = 0.017). Detraining led to regression of VO2peak toward baseline values (-8%; P = 0.03). No change was seen in the control group (-7%; P = 0.47). Performance in functional tests did not change significantly. Creatine kinase values were stable during the study. CONCLUSIONS: Moderate-intensity exercise seems to safely improve oxidative function in patients with Bethlem myopathy.

Upper-limb actuated exoskeleton for muscular dystrophy patients: preliminary results.

Being able to perform a lost movement is an important experience towards increased independence and self-esteem, particularly for neuromuscular patients, who see their muscles weaken day after day. In this pilot study, preliminary results on the testing of a motorized upper-limb exoskeleton for muscular dystrophy patients are presented. The mechatronic system is a five Degrees of Freedom exoskeleton, which acts at shoulder, elbow, and wrist levels. It is designed to help severely impaired people to regain independence during daily-life activities. While wearing the exoskeleton, the user has the direct control of the system by actively piloting the position of end-effector by means of joystick or vocal control. The usability of the system and a quantitative assessment of arm functionality with and without the exoskeleton are evaluated on five muscular dystrophy patients. According to the objective functional benefit evaluation performed through the PUL scale, all participants strongly increased their range of motion and they were able to perform activities that were not possible without the exoskeleton, such as such as feeding, playing activities at the table, combing hair or using a keyboard. As for the evaluation of self-perceived functional benefit, four patients reflected the effective measured functional improvement. System usability has been evaluated to be good.

Clinical features of children and adults with a muscular dystrophy using powered indoor/outdoor wheelchairs: disease features, comorbidities and complications of disability.

PURPOSE: To describe the clinical features of electric powered indoor/outdoor wheelchair users with a muscular dystrophy, likely to influence optimal prescription; reflecting features of muscular dystrophies, conditions secondary to disability, and comorbidities impacting on equipment provision. METHODS: Cross-sectional retrospective case note review of recipients of electric powered indoor/outdoor wheelchairs provided by a specialist regional wheelchair service. Data on demography, diagnostic/clinical, and wheelchair prescription were systematically extracted. RESULTS: Fifty-one men and 14 women, mean age 23.7 (range 10-67, s.d. 12.95) years, were studied. Forty had Duchenne muscular dystrophy, 22 had other forms of muscular dystrophy, and three were unclassified. Twenty-seven were aged under 19. Notable clinical features included problematic pain (10), cardiomyopathy (5), and ventilatory failure (4). Features related to disability were (kypho)scoliosis (20) and edema/cellulitis (3) whilst comorbidities included back pain (5). Comparison of younger with older users revealed younger users had more features of muscular dystrophy affecting electric powered chair provision (56%) whilst older users had more comorbidity (37%). Tilt-in-space was prescribed for 81% of users, specialized seating for 55% and complex controls for 16%. CONCLUSIONS: Muscular dystrophy users were prescribed electric powered indoor/outdoor chairs with many additional features reflecting the consequences of profound muscle weakness. In addition to facilitating independence and participation, electric powered indoor/outdoor chairs have major therapeutic benefits. Implications for rehabilitation Powered wheelchairs have therapeutic benefits in managing muscular dystrophy pain and weakness. The use of specialized seating needs careful consideration in supporting progressive muscle weakness and the management of scoliosis. Pain, discomfort, pressure risk, and muscle fatigue may be reduced by use of tilt-in-space.

Integrated care of muscular dystrophies in Italy. Part 2. Psychological treatments, social and welfare support, and financial costs.

This paper describes the psycho-social treatments received by 502 patients with MDs and their relatives, and the costs for care sustained by the families in the previous six month period. Data were collected by the MD-Care Schedule (MD-CS) and the Family Problems Questionnaire (FPQ). Psycho-educational interventions were provided to 72 patients (14.3%), and social/welfare support to 331 patients (65.9%). Social/welfare support was higher in patients with DMD or LGMD, in those showing more severe disability, and in patients who were in contact with centres located in Northern Italy. Psycho-educational interventions were received by 156 (31%) relatives, and social/welfare support by 55 (10.9%) and mainly provided by Family/Patients Associations (83.6%). Relatives with higher educational levels, who spent more daily hours in the assistance of patients with DMD, and in contact with centres in Central Italy more frequently benefited from psycho-educational interventions. In the previous year, costs for care were sustained by 314 (63.9%) relatives. Financial difficulties related to patient's condition, were higher in families of patients who needed more intensive rehabilitation and daily hours of caregiving, and in families who lived further away from the reference's centre. These results showed that psycho-social aspects of MDs care are only partially met in Italy, and that ad hoc supportive interventions for these patients and their families should be potentiated.

Physical exercise and oxidative stress in muscular dystrophies: is there a good balance?

The effect of oxidative stress on muscle damage inducted by physical exercise is widely debated. It is generally agreed that endurance and intense exercise can increase oxidative stress and generate changes in antioxidant power inducing muscle damage; however, regular and moderate exercise can be beneficial for the health improving the antioxidant defense mechanisms in the majority of cases. Growing evidences suggest that an increased oxidative/nitrosative stress is involved in the pathogenesis of several muscular dystrophies (MDs). Notably, physical training has been considered useful for patients with these disorders. This review will focus on the involvement of oxidative stress in MDs and on the possible effects of physical activities to decrease oxidative damage and improve motor functions in MDs patients.

Integrated care of muscular dystrophies in Italy. Part 1. Pharmacological treatment and rehabilitative interventions.

This paper describes the pharmacological therapies and rehabilitative interventions received by 502 patients with Muscular Dystrophies, evaluated in relation to patient's socio-demographic and clinical variables, and geographical areas. Data were collected by the MD-Socio-Demographic and Clinical Schedule (MD-SC-CS) and by the Family Problems Questionnaire (FPQ). The most part of the enrolled patients were in drug treatment. The number of the medications increased in relation to patient's age, disability degree and duration of illness and was higher among patients with Duchenne Muscular Dystrophy (DMD) compared with Becker (BMD) or Limb-Girdle Muscular Dystrophies (LGMD). Steroids (deflazacort or prednisone) were the drug most frequently used, followed by cardiologic and bone metabolism drugs. In general, patients using steroids were younger and had a shorter duration of illness; patients using cardiac drugs and dietary supplements were older and had a longer duration of illness. Rehabilitative interventions were provided to about 70% (351/502) of patients, mainly DMD. Of these, physiotherapy was the more frequent treatment (96.6%) and was prevalently performed in rehabilitative centres (about 70% of patients) and at home in only 30%. Hydrokinetic-therapy was practiced by 6.8% of patients. Respiratory rehabilitation was provided to 47.0% of patients (165/351) and assisted mechanical ventilaventilation to 13.1% (46). The amount of rehabilitative interventions increased in relation to the patient's age, level of disability and duration of illness. Compared to Central and Northern Italy, in Southern Italy there was a higher attention to cardiological impairment as shown by a higher number of patients receiving heart drugs. No statistically significant differences concerning the possibility to have access to rehabilitative interventions were noted among the three geographical areas. However, patient living in Southern Italy tend to receive rehabilitation more often at home.

Long-term non-invasive ventilation in muscular dystrophy.

Long-term non-invasive ventilation (NIV) was introduced in the 1980s, initially mainly for patients with poliomyelitis, muscular dystrophy (MD) or scoliosis. The obesity-hypoventilation syndrome has since become the commonest reason for referral to most centres providing home-NIV. Patients with MD are numerically a much smaller part of the workload, but as their disease progresses the need for ventilatory support changes and they require regular comprehensive assessment of their condition. We have examined the trend in MD use of home-NIV in our unit over the last 25 years. The number of new referrals appears to be stabilizing at around 20-25 over a 5-year period, equivalent to approximately 0.5 per 100,000 of population per year. The mean age at commencement of home-NIV is now 37.5 years, with 5-year survival rates of 70-75%. Ten-year survival rates are just over 40%. The distance of usual place of residence from our unit is fairly stable, currently at a mean of 27 km. Excellent survival rates mean that patients with MD, while numerically small, are likely to remain an important part of the workload of centres providing home-NIV. Our data should prove useful in the planning of future services for this group of patients.

Do Psychosocial Interventions Improve Quality of Life and Wellbeing in Adults with Neuromuscular Disorders? A Systematic Review and Narrative Synthesis.

Quality of life and well-being are frequently restricted in adults with neuromuscular disorders. As such, identification of appropriate interventions is imperative. The objective of this paper was to systematically review and critically appraise quantitative studies (RCTs, controlled trials and cohort studies) of psychosocial interventions designed to improve quality of life and well-being in adults with neuromuscular disorders. A systematic review of the published and unpublished literature was conducted. Studies meeting inclusion criteria were appraised using a validated quality assessment tool and results presented in a narrative synthesis. Out of 3,136 studies identified, ten studies met criteria for inclusion within the review. Included studies comprised a range of interventions including: cognitive behavioural therapy, dignity therapy, hypnosis, expressive disclosure, gratitude lists, group psychoeducation and psychologically informed rehabilitation. Five of the interventions were for patients with Amyotrophic Lateral Sclerosis (ALS). The remainder were for patients with post-polio syndrome, muscular dystrophies and mixed disorders, such as Charcot-Marie-Tooth disease, myasthenia gravis and myotonic dystrophy. Across varied interventions and neuromuscular disorders, seven studies reported a short-term beneficial effect of intervention on quality of life and well-being. Whilst such findings are encouraging, widespread issues with the methodological quality of these studies significantly compromised the results. There is no strong evidence that psychosocial interventions improve quality of life and well-being in adults with neuromuscular disorders, due to a paucity of high quality research in this field. Multi-site, randomised controlled trials with active controls, standardised outcome measurement and longer term follow-ups are urgently required.

Fisioterapia aquática no tratamento de criança com distrofia muscular congênita merosina negativa: relato de caso / Aquatic physical therapy in the treatment of a child with merosin-deficient congenital muscular dystrophy: case report

Este relato de caso descreve um programa de fisioterapia aquática para uma criança com distrofia muscular congênita (DMC) merosina negativa. Objetivo: Verificar a interferência da fisioterapia aquática na velocidade e no índice de gasto energético durante o deslocamento sentado em superfície plana, e no alcance funcional com os membros superiores devido a fraqueza proximal que acomete estes pacientes visando maior independência. Métodos: Como instrumentos de avaliação foram utilizados a Medida da Função Motora (MFM); o Functional Reach Test (FRT); foi verificado o Índice de Gasto Energético (IGE) no deslocamento sentado; assim como o tempo gasto neste deslocamento e a ativação muscular com a eletromiografia (EMG). O programa durou 12 semanas e a intervenção incluiu atividades para melhorar a mobilidade e a agilidade no deslocamento sentado e o alcance na postura sentada. Resultados: Na MFM a variação no escore das duas dimensões (D2 e D3) focadas na terapia foi de 6,8%. O alcance funcional melhorou 16 centímetros (cm) e o tempo do deslocamento sentado diminuiu 19 segundos (s). O gasto energético diminuiu 252,31 batimentos por minuto (bpm). Conclusão: A fisioterapia aquática foi eficaz para melhora da agilidade no deslocamento sentado e na funcionalidade de membros superiores (MMSS) de uma criança com DMC merosina negativa

This case report describes an aquatic therapy program for a child with Merosin-Deficient Congenital Muscular Dystrophy. Objective: This study sought to investigate the effect of aquatic physical therapy on the speed and the rate of energy expenditure while moving around on a flat surface, in addition to the functional reach of the upper limbs suffering from the proximal weakness that affects these patients seeking greater independence. Methods: The Motor Function Measurement (MFM) and the Functional Reach Test (FRT) were used as assessment tools; the Energy Expenditure Index (EEI) was measured in seated locomotion, as well as the time spent, and muscle activation was measured via electromyography (EMG). The program lasted 12 weeks and included activities to improve mobility and agility as well as reaching from the seated position. Results: In the MFM the change in the score of the two dimensions (D2 and D3) that the treatment focused on was 6.8%. The functional reach improved by 16 centimeters (cm) and the amount of time moving while sitting decreased by 19 seconds (s). Energy expenditure decreased by 252.31 beats per minute (bpm). Conclusion: The aquatic physical therapy was effective for agility improvement in seated locomotion and upper limb functionality of a 6-year-old child with Merosin-Deficient Congenital Muscular Dystrophy

Residential immersive life skills programs for youth with physical disabilities: A pilot study of program opportunities, intervention strategies, and youth experiences.

PURPOSE: A pilot study was conducted to assess correspondence among measures of program characteristics (opportunities and intervention strategies) and youth experiences in a range of activity settings in a residential immersive life skills (RILS) program. METHOD: Opportunities and intervention strategies were assessed in 18 activity settings in the 21-day program. On two occasions each, four youth completed a measure of experiences and took part in onsite interviews. RESULTS: There was good convergence between observed program opportunities and the use of socially-mediated, teaching/learning, and non-intrusive strategies. Youth experiences of social interaction, choice, and personal growth were further informed by interview information. There was substantial convergence between program characteristics and youth experiences, indicating the program was provided and experienced as intended. CONCLUSIONS: This pilot study indicated the fidelity of the program and the feasibility of using the measures in a future study. The preliminary findings suggest that RILS programs may provide a favorable environment for developmental experiences concerning social interaction, autonomy, and personal growth.

Falls among adults aging with disability.

OBJECTIVE: To investigate the prevalence of and risk factors for falling among individuals aging with multiple sclerosis (MS), muscular dystrophy (MD), postpolio syndrome (PPS), and spinal cord injury (SCI). DESIGN: Cross-sectional survey data from 2009 to 2010 were analyzed. We used forward logistic regression models to examine whether risk factors such as age, sex, mobility level, years since diagnosis, vision, balance, weakness, number of comorbid conditions, and physical activity could distinguish participants who reported falling from those who did not. SETTING: Surveys were mailed to community-dwelling individuals who had 1 of 4 diagnoses (MS, MD, PPS, or SCI). The survey response rate was 91%. PARTICIPANTS: A convenience sample of community-dwelling individuals (N=1862; age, 18-94y) with MS, MD, PPS, or SCI in the United States. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Self-reported fall within the last 6 months. RESULTS: Fall prevalence for people with MS (54%), MD (70%), PPS (55%), and SCI (40%). Across all 4 groups, fall rates peaked in middle age (45-64y) and among people with moderate mobility limitations. Seven risk factors differentiated participants who fell from those who did not: mobility level, imbalance, age, curvilinear age (age(2)), number of comorbid conditions, duration of diagnosis, and sex. The models differed across diagnostic groups. CONCLUSIONS: People aging with long-term physical disabilities experience unique challenges that affect their risk of falls. A better understanding of the frequency, severity, and risk factors of falls across diagnostic groups is needed to design and implement customized, effective fall prevention and management programs for these individuals.
