Assessing the modulation of cutaneous sensory fiber excitability using a fast perception threshold tracking technique.

abstract：INTRODUCTION:Duchenne muscular dystrophy (DMD) is a degenerative disease of skeletal, respiratory, and cardiac muscles caused by defects in the dystrophin gene. More recently, brain involvement has been verified. Mitochondrial dysfunction and oxidative stress may underlie the pathophysiology of DMD. In this study we ev...
