Hand and finger movements during mo

Hand and finger movements during most functional tasks are also more complex than leg and foot movements during gait,and even the simplest task requires the integration of several interrelated abilities.
For example, the relatively uncomplicated task of grasping a cup requires reaching for the cup, coordinating hand shape formation for grasping during reach, coordinating finger movements and fingertip forces during grasping and releasing, visuomotor coordination, tactile-motor coordination and finger individuation.
Impairment in any of these abilities can lead to hand dysfunction, and successful rehabilitation may depend on the identification and treatment of each of the specific underlying impairments. Alternatively, recovery may depend on global processes that affect these interrelated abilities simultaneously.
More likely, upper limb functional recovery is mediated by processes occurring at both global and task-specific levels.
At this time little is known about what specifically should be done to assist and maximize recovery of hand function. The lack of a theoretical framework for rehabilitation of upper limb function,especially once the patient is in his or her own environment in the community, is a significant impediment to use of the affected arm and hand in daily life.
