Spinal muscular atrophy (SMA) is an autosomal recessive neuromuscular disorder. With the emergence of disease-modifying therapies, the prognosis of SMA has significantly improved, drawing increased attention to the importance of home rehabilitation and nursing management. Long-term, standardized home rehabilitation and nursing can delay the progression of SMA, enhance the psychological well-being, and improve the quality of life of both patients and caregivers. This article provides an overview of the goals of home rehabilitation, basic functional training methods, respiratory management, and nutritional management for SMA patients, as well as psychological health issues, emphasizing the significance of obtaining appropriate home rehabilitation and support during the care process.

Feasibility and effectiveness of a novel dynamic arm support in persons with spinal muscular atrophy and duchenne muscular dystrophy.

BACKGROUND: Neuromuscular disorders (NMD) commonly affect the upper extremity. Due to muscle weakness, performance of daily activities becomes increasingly difficult, which leads to reduced independence and quality of life. In order to support the performance of upper extremity tasks, dynamic arm supports may be used. The Yumen Arm is a novel dynamic arm support specially developed for people with NMD. The aim of this study is to evaluate the feasibility and effectiveness of the Yumen Arm in persons with Duchenne Muscular Dystrophy (DMD) and persons with Spinal Muscular Atrophy (SMA). METHODS: Three persons with DMD and three persons with SMA participated in this study. All participants conducted a set of measures with and without the Yumen Arm. Outcome measures were: active range of motion of the arm and trunk (i.e. Reachable Workspace, Functional Workspace, and trunk movement), fatigue (OMNI-RPE), Performance of Upper Limb (PUL) scale and some additional activities of daily living. User experiences were collected using a questionnaire. RESULTS: The Yumen Arm could be used by all participants. Results showed a median increase in active range of motion (4% relative surface area), and a median increase of function ability (> 11% PUL score) when using the Yumen Arm. In addition, three out of four (data from 2 participants was missing) participants indicated that activity performance was less fatiguing when using the Yumen Arm. Four out of five (data from 1 participant was missing) participants indicated that they would like to use the Yumen Arm in their daily lives. CONCLUSION: This study is one of the first studies describing a range of objective measures to examine the effectiveness of a dynamic arm support. Based on these measurements we can conclude that the Yumen Arm effectively improves arm function in NMD patients, however the effectiveness varies a lot between individual subjects. We provided detailed recommendations for the improvement of the Yumen Arm, and possible also for the development of other dynamic arm supports. This study showed a lot of variability between individual subjects, which emphasizes the importance of tuning dynamic arm supports based on individual user characteristics, such as scoliosis, functional capacity and muscle strength.

Exploring spinal muscular atrophy and its impact on functional status: Indian scenario.

The present study aimed to find out the effect of disease-related impairments on functional status in individuals with spinal muscular atrophy and identify perceived barriers to undergo physiotherapy. The cross-sectional observational study was conducted on 90 participants from January to March 2018 using validated patient-reported questionnaire via electronic mail, along with Fatigue Severity Scale and ACTIVLIM. Results revealed that difficulty in sitting was due to scoliosis (36%) and muscle weakness (23%), the latter also contributing toward difficulty in standing and walking (59%). Inverse relationship exists between ACTIVLIM measures and fatigue severity scores (r = -0.338, P < 0.05), body mass index (r = -0.225, P < 0.05), age (r = -0.258, P < 0.05), and duration of illness (r = -0.257, P < 0.05). Economic constraints (27%), difficulty in traveling (17%), and lack of family support and mobility (14%) are perceived barriers to undergo physiotherapy. Functional impairments and identified barriers must be addressed as part of rehabilitation.

Conclusión: Las características clínico funcionales de los pacientes con AME, evidencian un grupo que presenta un alto nivel de dependencia en todos los tipos de la enfermedad, múltiples comorbilidades y alteraciones músculo-esqueléticas secundarias y por ello requiere de un programa de rehabilitación multidisciplinaria tal como lo describe la literatura internacional.

Introduction: Spinal muscular atrophy (SMA) is a severe neuromuscular disease (NMD) characterized by the loss of alpha motor neurons of the anterior horn of the spinal cord, causing progressive weakness of proximal muscles. Global prevalence is estimated to be 1/6,000-10,000 live births. There is limited data on SMA patients in the Chilean population. Objective: To establish the scale, demographics and functional-clinical characteristics of SMA patients attending Instituto Teletón Santiago (ITS). Patients and Method: Cross-sectional, descriptive study based on the review of ITS's data information system, clinical records and telephone surveys. Results: 62 SMA patients were identified attending regular controls at ITS, 49 (79%) were included in the study. 30.6%, 36.7% and 32.7% correspond to SMA 1, 2 or 3, respectively. Average age 10.6 ± 6.6 years; loss of gait at a median age of 6.8 years in SMA 3 patients. 67.3% require some type of breathing assistance, 44.9% have swallowing problems, 75.5% scoliosis, 49% hip dislocation or subluxation, 79.6% contracture of joints and 65.3% pain. In terms of social participation, 83% of recreational activities are carried out indoors, mainly related to the use of technology; and 77.5% go out to take part in social activities. Conclusion: Functional-clinical characteristics of SMA patients show that there is a group with high levels of dependence in all types of the disease, multiple concurrent disorders and secondary musculoskeletal conditions, and therefore, in the necessity to have a multidisciplinary rehabilitation system, as described in international literature.

Four-week trunk-specific exercise program decreases forward trunk flexion in Parkinson's disease: A single-blinded, randomized controlled trial.

INTRODUCTION: Pathological forward trunk flexion is a disabling and drug-refractory motor complication of Parkinson's disease (PD) leading to imbalance, pain, and fall-related injuries. Since it might be reversible, early and multidisciplinary management is emphasised. The primary aim was to compare the effects of a four-week trunk-specific rehabilitation program on the severity of the forward trunk flexion. The secondary aim was to compare the training effects on the motor impairments, dynamic and static balance, pain, falls, and quality of life. METHODS: 37 patients with PD (H&Y ≤ 4) and forward trunk flexion were randomized in the experimental (n = 19) or control group (n = 18). The former consisted of active self-correction exercises with visual and proprioceptive feedback, passive and active trunk stabilization exercises and functional tasks. The latter consisted of joint mobilization, muscle strengthening and stretching, gait and balance exercises. Protocols lasted 4 weeks (60 min/day, 5 days/week). Before, after, and at 1-month follow-up, a blinded examiner evaluated patients using primary and secondary outcomes. The primary outcome was the forward trunk flexion severity (degree). Secondary outcomes were the UPDRS III, dynamic and static balance, pain falls, and quality of life assessment. RESULTS: The experimental group reported a significantly greater reduction in forward trunk flexion than the control group from T0 to both T1 (p = 0.003) and T2 (p = 0.004). The improvements in dynamic and static balance were significantly greater for the experimental group than the control group from T0 to T2 (p = 0.017 and 0.004, respectively). Comparable effects were reported on the other outcomes. Pre-treatment forward trunk flexion values were highly correlated to post-treatment trunk deviation changes. CONCLUSION: The four-week trunk-specific rehabilitation training decreased the forward trunk flexion severity and increased postural control in patients with PD. NCT03741959.

Measurement of camptocormia trunk flexion using a dual-sensor measurement setup.

Assessing the flexion of the trunk of patients with camptocormia is a key factor in developing therapies for camptocormia and monitoring their success. Currently used methods to measure this camptocormia angle are based on photographs or short videos. Both methods are not able to take the ability of patients into account to compensate their symptoms for short amounts of time. We propose a simple two sensor measurement setup based on two accelerometers to measure the angle in accordance with the established perpendicular measurement method [1]. We show that our method yields an average deviation of -1.74° with a maximum deviation of +2° and -6° compared to visual assessment with a motion capturing system.

Late onset of dropped head syndrome following mantle radiation therapy for Hodgkin lymphoma.

Dropped head syndrome (DHS) is a rare condition, characterised by weakness of the cervical paraspinal muscles with sagging of the head. It is usually seen in association with neurological disorders and rarely can follow radiotherapy. We report a case of a 54-year-old man survivor of Hodgkin lymphoma (HL), who developed DHS 28 years after radiotherapy. He was referred to our department due to progressive weakness and atrophy of cervical paraspinal and shoulder girdle musculature. Physical and neurophysiological examination, electromyography and MRI confirmed the diagnosis of DHS. In the following years, there was no progression of symptoms.

Social participation of adult patients with spinal muscular atrophy: Frequency, restrictions, satisfaction, and correlates.

INTRODUCTION: In this study we assessed social participation in 62 adults with spinal muscular atrophy (SMA) types 1c-4. METHODS: The outcome measure used was the Utrecht Scale of Evaluation Rehabilitation-Participation (USER-P) with Frequency, Restrictions, and Satisfaction scores, and a hierarchical regression analysis. RESULTS: Early-onset (types 1, 2, and 3a) and late-onset (types 3b and 4) SMA patients reported similar frequency and satisfaction scores. "Age," "motor skills," "pain," and "feelings of depression" correlated with frequency; "motor skills" and "feelings of depression" correlated with restrictions; and "level of education," "fatigue," and "feelings of depression" correlated with satisfaction. "Motor skills" and "feelings of depression" explained 33% of variance in frequency of participation. "Motor skills" explained 26% of variance of restrictions in participation. "Fatigue" and "feelings of depression" explained 50% of variance in satisfaction with participation. DISCUSSION: Motor skills, feelings of depression and fatigue are correlates of participation in daily life. This knowledge can be used to optimize care for SMA patients.

Manual Feeding Device Experiences of People With a Neurodisability.

OBJECTIVE: Neurological bilateral upper limb weakness can result in self-feeding difficulties and reliance on care providers. Mealtimes become time consuming and frustrating. In this exploratory inquiry, we examined the experiences of users of a feeding device. METHOD: Semistructured interviews were either conducted by telephone or administered via email to explore quality of life, changes to independence, benefits and limitations, and psychological impact of the equipment. RESULTS: Thematic analysis gave rise to five themes: independence and positivity, emotions, impact on family and social life, equipment functionality, and motivation. CONCLUSION: This exploratory inquiry has contributed new qualitative evidence to the knowledge and understanding of users' experiences of a manual feeding device. Users reported that the need for assistance was reduced and that their quality of life, independence, and freedom improved. Time and resources savings for the family, care providers, and staff appeared to result in a more equal relationship between user and care provider.

Gait dynamics in Pisa syndrome and Camptocormia: The role of stride length and hip kinematics.

This is an observational cross-sectional study evaluating gait dynamics in patients with Parkinson's Disease (PD) and severe postural deformities, PD without axial deviations and healthy subjects. Ten PS individuals with Pisa syndrome (PS) and nine subjects with Camptocormia (CC) performed 3-D Gait Analysis and were evaluated with walking and balance scales. Correlations with clinical and functional scales were investigated. Spatio-temporal and kinematic data were compared to ten PD subjects without postural deformities (PP) and ten healthy matched individuals (CG). Data obtained showed decreased walking velocity, stride and step length in PP, PS and CC groups compared to controls. The correlation analysis showed that stride and step length were associated with reduced functional abilities and disease severity in PS and CC groups. Kinematic data revealed marked reduction in range of movements (ROMs) at all lower-extremity joints in PS group. While, in CC group the main differences were pronounced in hip and knee joints. PS and CC groups presented a more pronounced reduction in hip articular excursion compared to PP subjects, revealing an increased hip flexion pattern during gait cycle. Moreover, the increased hip and knee flexion pattern adversely affected functional performance during walking tests. Results obtained provide evidence that step length, along with stride length, can be proposed as simple and clear indicators of disease severity and reduced functional abilities. The reduction of ROMs at hip joint represented an important mechanism contributing to decreased walking velocity, balance impairment and reduced gait performance in PD patients with postural deformities.

Management of scoliosis in patients with Duchenne muscular dystrophy and spinal muscular atrophy: A literature review.

Scoliosis occurs in nearly all non-ambulatory children with spinal muscular atrophy (SMA) and Duchenne muscular dystrophy (DMD). Non-operative treatments have not been shown to be effective at preventing progression of scoliosis. Progressive scoliosis can impact the ability of patients to sit comfortably, be cosmetically unappealing, and in severe cases exacerbate pulmonary disease. The main goal of operative treatment is to improve sitting balance and prevent progression of scoliosis. Complication rates are high and there is little data on effect of operative treatment on quality of life in children with SMA and DMD. Comprehensive multi-disciplinary pre-operative evaluations are vital to reduce the risks of operative treatment.

Physical therapy services received by individuals with spinal muscular atrophy (SMA).

PURPOSE: The consensus statement for standard of care in SMA recommends multidisciplinary medical care including physical therapy (PT) services. To date there are no reports regarding the implementation of these recommendations and the type of care or services received by individuals with SMA. The purpose of this study is to describe the PT services received by individuals with SMA. METHODS: Interviews were conducted with patients or their caregivers at the Pediatric Neuromuscular Clinical Research (PNCR) Network sites from October 2011 to September 2012. Questions included information about clinical status of the patient, sociodemographic profile of the patient or caregiver, and PT services received in the past year, including the setting, frequency, duration and type of PT, and therapies administered by caregivers. RESULTS: Eighty-six percent of 105 participants reported receiving PT services, some in multiple settings: 62% in the neuromuscular clinic, 38% at school, 34% at home, and 13% in an outpatient clinic. Greater frequency of PT services received was associated with younger age and inability to walk, but not SMA type. CONCLUSION: This is the first multicenter study documenting PT services received by patients with SMA. Further research is needed to better understand the impact of PT services on the natural history of SMA.

Introduction. The Egen Klassifikation 2 Scale (EK2), expansion of the EK scale, assesses the functional capacity of people with spinal muscular atrophy (SMA) and Duchenne muscular dystrophy (DMD) that are in wheelchair phase. This version is more specific for SMA than its EK predecessor. Aim. To examine the validity and reliability of the Spanish version of the scale as a tool for measuring the functional capacity in patients with DMD and SMA who are in wheelchairs. Patients and methods. First, a translation-back-translation into Spanish of the English version of the EK2 was performed; later, we studied the reliability of the translated version. For this, 39 patients, aged between 4 and 60, who were evaluated by two observers, were recruited. To evaluate the intra-observer consistency, two assessments by the same observer were performed, and the inter-observer third assessment was performed by a second observer. Results. The obtained values based on the total score of the scale items (sum EK2) reflect excellent intra- and inter-observer reliability, 0.993 and 0.988 respectively. Also, for each of the items, reliability was excellent except for one item in which it was good. Conclusions. The Spanish version of the EK2 scale is a valid and reliable instrument for the Spanish population as a tool for measuring the functional capacity in patients with SMA and DMD who are in wheelchairs (AU)

Resistance strength training exercise in children with spinal muscular atrophy.

INTRODUCTION: Preliminary evidence in adults with spinal muscular atrophy (SMA) and in SMA animal models suggests exercise has potential benefits in improving or stabilizing muscle strength and motor function. METHODS: We evaluated feasibility, safety, and effects on strength and motor function of a home-based, supervised progressive resistance strength training exercise program in children with SMA types II and III. Up to 14 bilateral proximal muscles were exercised 3 times weekly for 12 weeks. RESULTS: Nine children with SMA, aged 10.4 ± 3.8 years, completed the resistance training exercise program. Ninety percent of visits occurred per protocol. Training sessions were pain-free (99.8%), and no study-related adverse events occurred. Trends in improved strength and motor function were observed. CONCLUSIONS: A 12-week supervised, home-based, 3-day/week progressive resistance training exercise program is feasible, safe, and well tolerated in children with SMA. These findings can inform future studies of exercise in SMA.

An examination of camptocormia assessment by dynamic quantification of sagittal posture.

OBJECTIVE: Camptocormia is a disabling pathology of the axial system that debilitates patients in their daily life. To date, there have been no studies evaluating the impact of camptocormia on walking performance. This study presents a new method for assessing sagittal posture under walking conditions in patients with camptocormia. DESIGN: The severity of camptocormia was evaluated by measuring sagittal inclination, represented indirectly by the horizontal distance between the C7 and S1 markers (C7 sagittal arrow; C7-SAR). Sagittal inclination was measured under various behavioural conditions using clinical, radiological and kinematic approaches. PATIENTS: Forty-three patients were included in the study (17 with Parkinson's disease and 26 with idiopathic camptocormia). RESULTS: Under static conditions, C7-SAR could be assessed using different methods. During walking, there was a dramatic increase in C7-SAR values. Correlation analysis revealed a relationship between functional impairment and dynamic C7-SAR values, but not with radiological C7-SAR values. PATIENTS with Parkinson's disease behaved differently from idiopathic patients, suggesting the involvement of different underlying physiopathological mechanisms. CONCLUSION: Monitoring sagittal inclination during walking is more accurate than radiological measurements to determinine the detrimental effects of camptocormia and its consequences for quality of life.

Mechanical insufflation/exsufflation improves vital capacity in neuromuscular disorders.

Inherited neuromuscular disorders inevitably result in severe lung volume restriction associated with high morbidity and mortality. The aim of this retrospective study was to evaluate the long-term effects of the regular use of mechanical insufflation/exsufflation on the course of the vital capacity. This retrospective data analysis included 21 patients (16.1 ± 6.5 years) with neuromuscular disorders and severe lung volume restriction using nocturnal noninvasive ventilation. The patients were advised to regularly use the mechanical insufflation/exsufflation twice a day for 10 minutes applying sets of three insufflation/exsufflation breath via face mask irrespective of respiratory tract infection. Data on the course of vital capacity were collected 2 years prior and 2 years after the introduction of regular use of mechanical insufflation/exsufflation. Before the introduction of mechanical insufflation/exsufflation vital capacity decreased from 0.71 ± 0.38 L to 0.50 ± 0.24 L in the last year and from 0.88 ± 0.45 L to 0.71 ± 0.38 L in the next to last year. In the first year, after regular use of mechanical insufflation/exsufflation vital capacity significantly increased by 28% (from 0.50 L to 0.64 L)-after the second year the vital capacity increase remained stable (0.64 vs. 0.65 L). These data suggest that the regular use of mechanical insufflation/exsufflation improves vital capacity in patients with neuromuscular disorders and severe lung volume restriction.
