F- and M-wave conduction velocity in amyotrophic lateral sclerosis.

abstract：INTRODUCTION:Skeletal muscle oxidative capacity decreases and fatigability increases after spinal cord injury. Transcription factor peroxisome proliferator-activated receptor δ (PPARδ) promotes a more oxidative phenotype. METHODS:We asked whether PPARδ overexpression could ameliorate these deficits in the medial gastr...
