    Dr. Trumbower's research focuses on neural mechanisms underlying the control of movement and posture in persons with neuromotor deficits such as spinal cord injury and!stroke. The goal is to identify and prescribe therapeutic interventions that target impaired neural structures and promote functional recovery.
