Grip force regulation during pinch grip lifts under somatosensory guidance: Comparison between people with stroke and healthy controls

Abstract

Objectives: To compare the timing and grip force application in a pinch grip task performed under somatosensory guidance in stroke and matched controls and to identify characteristics of impaired grip force regulation after stroke. Design: Matched-pairs control group. Setting: University research laboratory. Participants: Forty-five people with stroke who could pick up a pen lid using a pinch grip and actively participated in rehabilitation and 45 adults without neurologic conditions or musculoskeletal or skin impairments affecting the hand, matched for age, sex, and hand dominance. Interventions: Not applicable. Main Outcome Measures: Timing and magnitude of grip forces applied during pinch..
