The muscular dystrophies (MD) are a heterogeneous group of inherited disorders characterized by findings on muscle biopsy. In general, they feature progressive muscle wasting and weakness. In addition to the musculoskeletal system, direct and indirect effects can be seen in a variety of organ systems. These issues create challenges in patients with MD for ambulation and mobility, self-care, pain, fatigue, and community involvement. Because of its progressive nature and wide variety of pathophysiological mechanisms, patients with MD require individualized rehabilitation care. This chapter reviews specific rehabilitation needs and treatment of patients with MD.

Background: Adeno-associated virus (AAV) 8 and 9 are in clinical trials for treating neuromuscular diseases such as Duchenne muscular dystrophy (DMD). Muscle consists of myofibres of different types and sizes. However, little is known about the fibre type and fibre size tropism of AAV in large mammals.

Background: Transient receptor potential cation channel subfamily V member 2 (TRPV2) functions as a stretch-sensitive calcium channel, with overexpression in the sarcolemma of skeletal and cardiac myocytes leading to detrimental calcium influx and triggering muscle degeneration. In our previous pilot study, we showed that tranilast, a TRPV2 inhibitor, reduced brain natriuretic peptide levels in two patients with muscular dystrophy and advanced heart failure. Building on this, we performed a single-arm, open-label, multicenter study herein to evaluate the safety and efficacy of tranilast in the treatment of advanced heart failure in patients with muscular dystrophy.

Background: Distal myopathies (MPDs) are heterogeneous diseases of complex diagnosis whose prevalence and distribution in specific populations are unknown.
Methods: Demographic, clinical, genetic, neurophysiological, histopathological and muscle imaging characteristics of a MPDs cohort from a neuromuscular reference center were analyzed to study their epidemiology, features, genetic distribution and factors related to diagnosis.
Results: The series included 219 patients (61% were men, 94% Spanish and 41% sporadic cases).

Background: Reduced forced vital capacity (FVC) is associated with morbidity and mortality in individuals with Duchenne muscular dystrophy (DMD). Non-invasive ventilation (NIV) is often prescribed for the treatment of sleep-disordered breathing (SDB), and chronic respiratory insufficiency. Despite the common practice of initiating NIV later in the progression of DMD, the factors influencing FVC subsequent to the commencement of NIV remain unclear.

Limb-girdle muscular dystrophy type 2E/R4 (LGMD2E/R4) is a rare disease that currently has no cure. It is caused by defects in the gene, mainly missense mutations, which cause the impairment of the sarcoglycan complex, membrane fragility, and progressive muscle degeneration. Here, we studied the fate of some β-sarcoglycan (β-SG) missense mutants, confirming that, like α-SG missense mutants, they are targeted for degradation through the ubiquitin-proteasome system.
