Neuroprotective effect of epidural electrical stimulation against ischemic spinal cord injury in rats: electrical preconditioning.

abstract：BACKGROUND:Physiologic data that is automatically collected during anesthesia is widely used for medical record keeping and clinical research. These data contain artifacts, which are not relevant in clinical care, but may influence research results. The aim of this study was to explore the effect of different methods o...
