Abstract
This prospective cohort study used video electromyography synchronized analysis to determine the dynamic use of extrinsic and intrinsic finger flexion during grasp. Light fist formation primarily involved the flexor digitorum profundus with either the flexor digitorum superficialis or intrinsics. In contrast, both the flexor digitorum superficialis and intrinsics were recruited in all tight fist video electromyography. However, the sequence of recruitment differed between patients in tight fist formation. Injured patients demonstrated a unique pattern of recruitment based on injury. The authors conclude that the flexor digitorum profundus is the workhorse in composite fist formation but the roles of the flexor digitorum superficialis and the intrinsic muscles are less consistent across patients.
