Argyrios Stampas, MD

My fellowship in SCI allowed me to incorporate electric stimulation in the outpatient rehabilitation of SCI. I have been able to take that education with me and use it in the inpatient rehabilitation setting. Now as a clinical researcher, I want to advance the field of acute rehabilitation using electric stimulation in the acute period to prevent problems commonly found in chronic spinal cord injury, including neurogenic bladder, autonomic dysreflexia, and spasticity.
