Abstract
OBJECTIVE To determine the physical strain of walking and assess its relationship with daily steps and intensity of daily activity in people with neuromuscular diseases. DESIGN Cross-sectional study. SUBJECTS/PATIENTS Sixty-one adults with neuromuscular diseases. METHODS Physical strain of walking, defined as oxygen consumption during comfortable walking relative to peak oxygen uptake. Daily step count and daily time spent in moderate and vigorous physical activity were assessed using accelerometry and heart rate measurements, respectively. Regression analyses assessed the relationships between log daily step count and log daily time spent in moderate and vigorous physical activity, and physical strain of walking. RESULTS The mean (standard deviation) physical strain of walking was 73 (20)% Log daily step count and physical strain were negatively associated (β = -0.47). No association was found with log daily time spent in moderate and vigorous physical activity. CONCLUSIONS The highly increased physical strain of comfortable walking indicates that walking is very demanding for people with neuromuscular diseases and is associated with a reduction in daily step activity. The absence of a relationship between intensity of activities and physical strain indicates that, despite a reduction in daily step activity, strenuous daily activities may still be performed.

Generalized myasthenia gravis with acetylcholine receptor antibodies: A guidance for treatment. Eur J Neurol 2024; 31:e16229. [PMID: 38321574 PMCID: PMC11236053 DOI: 10.1111/ene.16229] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Revised: 01/16/2024] [Accepted: 01/16/2024] [Indexed: 02/08/2024]
Abstract
BACKGROUND Generalized myasthenia gravis (MG) with antibodies against the acetylcholine receptor is a chronic disease causing muscle weakness. Access to novel treatments warrants authoritative treatment recommendations. The Nordic countries have similar, comprehensive health systems, mandatory health registers, and extensive MG research. METHODS MG experts and patient representatives from the five Nordic countries formed a working group to prepare treatment guidance for MG based on a systematic literature search and consensus meetings. RESULTS Pyridostigmine represents the first-line symptomatic treatment, while ambenonium and beta adrenergic agonists are second-line options. Early thymectomy should be undertaken if a thymoma, and in non-thymoma patients up to the age of 50-65 years if not obtaining remission on symptomatic treatment. Most patients need immunosuppressive drug treatment. Combining corticosteroids at the lowest possible dose with azathioprine is recommended, rituximab being an alternative first-line option. Mycophenolate, methotrexate, and tacrolimus represent second-line immunosuppression. Plasma exchange and intravenous immunoglobulin are used for myasthenic crises and acute exacerbations. Novel complement inhibitors and FcRn blockers are effective and fast-acting treatments with promising safety profiles. Their use depends on local availability, refunding policies, and cost-benefit analyses. Adapted physical training is recommended. Planning of pregnancies with optimal treatment, information, and awareness of neonatal MG is necessary. Social support and adaptation of work and daily life activities are recommended. CONCLUSIONS Successful treatment of MG rests on timely combination of different interventions. Due to spontaneous disease fluctuations, comorbidities, and changes in life conditions, regular long-term specialized follow-up is needed. Most patients do reasonably well but there is room for further improvement. Novel treatments are promising, though subject to restricted access due to costs.

Complement Ther Med 2024; 81:103033. [PMID: 38458542 DOI: 10.1016/j.ctim.2024.103033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Revised: 03/03/2024] [Accepted: 03/05/2024] [Indexed: 03/10/2024] Open
Abstract
OBJECTIVE To provide a comprehensive overview of existing evidence, research gaps, and future research priorities concerning the treatment of myasthenia gravis (MG) using exercise therapies. METHOD Clinical studies on exercise treatment for MG were searched in nine databases to conduct a scoping review. Two independent researchers screened the literature and comprehensively analyzed the characteristics and limitations of the included articles. RESULTS A total of 5725 studies were retrieved, of which 24 were included. The included studies were conducted in 16 different countries/regions and 456 patients were enrolled. Study designs included both interventional and observational studies. Exercise interventions included aerobic exercise, resistance exercise, balance training, and stretch training, and are typically administered in conjunction with medication, usual care, or some other interventions. The intensity, frequency, and duration of exercise interventions varied hugely among studies. Six-minute walk test, adverse events, muscle strength, MG quality of life-15 scale, forced vital capacity, quantitative MG scale, and MG activities of daily living scale were the most frequently used outcomes. All studies reported results in favor of the efficacy and safety of exercise in MG, and exercise-related adverse events were reported in two studies. CONCLUSION This scoping review provides an overview of the evidence concerning exercise treatment for MG. Key gaps in evidence include a limited number of participants, complex interventions, variability in outcome selection, and insufficient reporting in publications. The promotion of exercise treatment for MG still encounters several obstacles. A larger population, rigorous study design and conduction, standardized interventions and outcomes, and standardized reporting are essential.

Perspectives of people with myasthenia gravis on physical activity and experience of physical activity advice from health professionals in the Australian context: a qualitative study. Disabil Rehabil 2024:1-8. [PMID: 38613411 DOI: 10.1080/09638288.2024.2338877] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Accepted: 03/31/2024] [Indexed: 04/14/2024]
Abstract
PURPOSE Physical activity is an important modifiable determinant of health. There has been a historical aversion to movement in people with myasthenia gravis (MG) due to the pathophysiology of the disease, however, research suggests engagement in physical activity is safe and does not exacerbate symptoms. There are currently no studies investigating the qualitative perspectives of people with MG on physical activity. The aim of this study was to explore perceptions of physical activity, barriers, enablers, and participants' experiences of physical activity advice from health professionals. MATERIALS AND METHODS Semi-structured interviews were used, with verbatim transcripts analysed using content analysis. RESULTS Ten adults (median age 64.5 years) living in Australia with generalised MG were interviewed. Key findings were identified: (1) Physical activity is perceived to be important for general health and for MG; (2) Medical management and social support are key enablers; (3) Fatigue and pain are potential barriers; and (4) Experiences with healthcare professionals were considered insufficient and failed to provide disease specific advice regarding MG and physical activity. CONCLUSION People with MG have unique barriers and enablers to physical activity engagement that clinicians should consider when providing physical activity behaviour change support to this population.

Abstract
OBJECTIVES To investigate the presence of increased neuromuscular fatigue (NMF) in individuals with myasthenia gravis (IwMG), compared to healthy controls. A secondary aim was to assess associations between NMF, strength and perceived health-related quality of life (HRQoL) and symptom severity in IwMG. METHODS In this cross-sectional study, we assessed NMF using classical myoelectrical indicators (root mean square: RMS, mean power frequency: MPF) obtained from surface electromyography (sEMG) during a sustained submaximal isometric contraction of the right Biceps Brachii and the right Vastus Lateralis and by evaluating the post-effort decline in peak torque following a fatiguing task consisting of a 40-second sustained isometric contraction. Relationships with MG-specific clinical scores (Myasthenia Muscle Score for symptom severity, MGQOL-15-F for HRQoL) were investigated. RESULTS Forty-one females with MG were compared to 18 control females of similar age. IwMG demonstrated reduced strength in both muscle groups, compared to control subjects. In both populations and both limbs, NMF was demonstrated by an increase in RMS and a decrease in MPF. However, IwMG did not demonstrate greater NMF based on these myoelectrical indicators nor based on post-effort peak torque decline. DISCUSSION Despite a decrease in baseline strength, IwMG did not display greater NMF in this specific experimental paradigm. This cohort consisted of individuals with mild-to-moderately severe MG which was well-controlled and stable. Further studies are warranted to identify simple and reliable methods to measure NMF in MG and to understand the relationship between NMF and perceived fatigue in activities of daily living for IwMG.

Abstract
BACKGROUND Despite improvements in the medical management of myasthenia gravis (MG) in recent years, patients continue to report poor health and wellbeing outcomes such as high levels of fatigue, reduced quality of life (QoL), walking limitation and lowered balance confidence. Physical activity has been shown to be associated with these outcomes in other populations, however, there has been limited research in adults with MG. OBJECTIVE To describe physical activity and sedentary behaviour in adults with MG and to explore associations between these behaviours and fatigue, QoL, balance confidence and walking limitation. METHODS A self-report online survey was used to assess physical activity, sedentary behaviour, fatigue, QoL, balance confidence and walking limitation in adults with MG. Multiple linear regression was used to examine associations and descriptive statistics were used to analyse participant characteristics, physical activity, and sedentary behaviour. RESULTS Eighty-five adults with MG were included (mean age 48±16 years). Over half of participants (n = 53, 62.4%) reported sufficient physical activity to meet public health guidelines. Participants reported an average of 9 h/day of sedentary time (mean 9.0±3.5). Physical activity and fatigue (R2 = 0.196), QoL (R2 = 0.330), walking limitation (R2 = 0.305) and balance confidence (R2 = 0.304) were significantly (p < 0.05) and positively correlated, with no associations found for sedentary behaviour. When patterns of physical activity and sedentary behaviour were combined, lower fatigue (R2 = 0.213), higher QoL (R2 = 0.364), reduced walking limitation (R2 = 0.341) and higher balance confidence (R2 = 0.279) was observed in patients who had greater physical activity levels (> 150 mins/week) and lower sedentary time (< 10 h/day). CONCLUSIONS Higher physical activity and lower sedentary behaviour is associated with favorable health and wellbeing outcomes in adults with MG. Further research is required to ascertain whether these behaviours may be an appropriate target intervention to improve outcomes in this population.
