Anodal sensory nerve action potentials: From physiological understanding to potential clinical applicability.

abstract：INTRODUCTION:Immune-mediated myopathies are a heterogeneous group of chronic autoimmune disorders. Autoantibodies associated with this disease complex are classified into myositis-associated and myositis-specific. Anti-tRNA synthetase antibodies are the most well known of the myositis-specific antibodies. Previous repo...

abstract：:The model of chronic low-frequency stimulation for the study of muscle plasticity was developed over 30 years ago. This protocol leads to a transformation of fast, fatigable muscles toward slower, fatigue-resistant ones. It involves qualitative and quantitative changes of all elements of the muscle fiber studied so fa...
