Effects of activation pattern on human skeletal muscle fatigue.

abstract：INTRODUCTION:Peripheral nerves are often exposed to mechanical stress leading to compression neuropathies. The pathophysiology underlying nerve dysfunction by chronic compression is largely unknown. METHODS:We analyzed molecular organization and fine structures at and near nodes of Ranvier in a compression neuropathy ...
