Maximum voluntary contraction in dystrophinopathies % · patients with muscular dystrophies

Maximum voluntary contraction in myotonic dystrophy type 1 % · patients with muscular dystrophies

Maximum voluntary contraction in myotonic dystrophy type 2 % · patients with muscular dystrophies

Maximum voluntary contraction in glycogen storage disease type V % · patients with metabolic myopathies

Upper extremity maximum voluntary isometric contraction score at 3 months Quantitative Muscle Assessment (QMA) system. Data were normalized, summed and averaged to yield an U/E megascore (higher is better). · people with amyotrophic lateral sclerosis or motor neuron disease

Lower extremity maximum voluntary isometric contraction score at 3 months Quantitative Muscle Assessment (QMA) system. Data were normalized, summed and averaged to yield a L/E megascore (higher is better). · people with amyotrophic lateral sclerosis or motor neuron disease

Change in maximal isometric voluntary contraction force (Nm) · patients with people with peripheral neuropathy
