Furthermore, it is unknown whether cognitive-motor processes are differentially affected in men and women with advancing age.

Does the contribution of the paretic hand to bimanual tasks change with grip strength capacity following stroke?

Introduction: The majority of tasks we perform every day require coordinated use of both hands. Following a stroke, the paretic hand contribution to bimanual tasks is often impaired, leading to asymmetric hand use. Grip strength is a commonly used clinical indicator of progress towards stroke motor recovery.
