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.

Detailed Description:
This study is a prospective physiological study in a pathological condition (neuromuscular diseases).
5 groups of voluntary participants will be investigated:
1\. 20 subjects affected by Dystrophin related muscular dystrophy (Becker Muscular Dystrophy ) 2. Subjects affected by muscular dystrophy not related to dystrophin impairment : 20 subjects affected by facioscapulohumeral dystrophy and 20 subjects affected by Limb Girdle Muscular dystrophy 3. 20 subjects affected by non-dystrophic myopathies (Congenital myopathies ) 4. 20 subjects affected by motor diseases: amyotrophic lateral sclerosis(ALS), Charcot Marie Tooth disease, Spinal Muscular Atrophy .
5\. 20 healthy controls Objective: asses the muscular oxygenation modifications during a standardized effort and compare the variables between groups. Analyze the mitochondrial function and phenotype in the BMD group compared to healthy controls Outcome : Muscle Oxygenation by Near Infrared Spectroscopy parameters; oxygen consumption, Muscle Function Measure, Vignos and Brooke score, Borg scale, 6 minutes walk test, mitochondrial phenotype, mitochondrial oxygenation 3 visits : 1- inclusion 2- standardized effort protocol 3- for Becker dystrophy patients and voluntary controls, muscle biopsy of the Vastus Lateralis
