Neuromuscular diseases (NMD) are characterized by their great diversity, both clinically and genetically. They affect children as well as adults and have in common the impairment of one or more elements making up the motor unit. The vast majority are linked to genetic defects, especially in the pediatric population, but it can have another origin, notably autoimmune. Muscle weakness and exercise intolerance are particularly common symptoms, especially in metabolic or mitochondrial myopathies. If the beneficial effects of physical activity and training begin to be revisited in an increasing number of MNMs, the problem of practicing sport remains.
In an article published in April 2020, Italian researchers report the results of a multicenter study conducted in 38 patients with different forms of MNM (Duchenne or Becker dystrophinopathies, SMA, etc.) and regularly practicing sport. They were between 13 and 49 years old. Were assessed self-esteem, level of anxiety or depression, personality traits and quality of life. The results were compared with those obtained in other patients of the same age suffering from MNM but without sports. On all the parameters analyzed, the beneficial effect of sport on the psychosocial level was notable. The authors consequently emphasize the interest of the adapted sporting activity in this population, as long as medical contraindications are observed, in particular cardiac.
