Brief Summary
Previous studies showed modifications of muscle oxygenation parameters in muscular dystrophies du to an impairment or an absence of dystrophin. Our study aim at assessing muscle oxygenation during effort in different neuromuscular diseases (muscular dystrophies related and not related to dystrophin, non dystrophic myopathies and motor neuron diseases) compared to a group of healthy controls. Patients and controls are invited to perform an inframaximal , standardized effort of the knee extensors by the mean of an isokinetic dynamometer. Muscle oxygenation parameters are assessed through a Near Infrared Spectroscopy (NIRS) Device. In patients affected by dystrophin related myopathies, a muscle biopsy will be performed in order to analyse mitochondrial oxygenation parameters and mitochondrial phenotype. Our Hypothesis is that muscle oxygenation is impaired in dystrophin related muscular dystrophies compared to other neuromuscular diseases and healthy controls because of lack of muscle capillary vessels dilatation during effort and impairment of mitochondrial function.

Interventions
Subjects will be invited to perform an isokinetic effort of the knee extensors against an isokinetic dynamometer. During this effort, muscle oxygenation and oxygen consumption will be assessed with a near infrared spectroscopy device and a gas exchange measurement device. Patients affected by Becker muscular dystrophy and healthy controls will be invited to have a muscle biopsy of the vastus lateralis.
