Arm Tremor During Reach in People with Multiple Sclerosis

Data sample from arm tremor projectUpper extremity tremor during goal-directed movement is a common symptom in Multiple Sclerosis (MS) that can have a devastating impact on the ability of individuals to perform activities of daily living. Current rehabilitation strategies are generally ineffective due in part to an incomplete understanding of how the sensorimotor control system is impaired. Our lab focuses on developing approaches to characterize sensorimotor control model of goal-directed movement within individual subjects to investigate how sensorimotor control is impaired in people with Multiple Sclerosis.
