Ethical review of research involving human subjects: when and why is IRB review necessary?

abstract：INTRODUCTION:In this study we noninvasively evaluated skeletal muscle mitochondrial capacity, muscle-specific endurance, and energy/fatigue feelings in persons with Friedreich ataxia (FRDA) and able-bodied controls (AB). METHODS:Forearm mitochondrial capacity was measured in FRDA (n = 16) and AB (n = 10) study partici...
