Functional Anatomy of the Hand - Physiopedia. Introduction. The hand contains a number of joints that allow complex actions, such as manipulating, gripping and grasping objects. Optimal hand function requires adequate strength, sensation, range of motion, and dexterity.
In the limbs, flexion decreases the angle between the bones (bending of the joint), while extension increases the angle and straightens the joint. For the upper limb, all anterior-going motions are flexion and all posterior-going motions are extension.
Hand exercises are a beneficial intervention for improving hand mobility, strength, and functional ability. They may include: Mobilizing exercises to increase or maintain range of motion. Strengthening exercises using resistance from putty, a gel ball, or elastic bands. Stretching exercises to increase muscle flexibility of the fingers and wrist.
