Hand therapy is the art and science of evaluating and treating injuries and conditions of the upper extremity (shoulder, arm, elbow, forearm, wrist and hand). It uses a number of therapeutic interventions to help return a person to their highest level of function. It evolved from the need for a specialist with the knowledge and experience required to manage the challenging recovery of complex hand and upper extremity injuries.  Hand therapists bridge the gap from medical management of upper extremity conditions to successful recovery, allowing individuals to function normally in their daily lives. Hand therapists provide non-operative interventions, preventative care and post-surgical rehabilitation for a wide variety of upper extremity disorders, from simple fingertip injuries to complex replanted extremities.  A hand therapist employs a variety of techniques and tools, including activity and exercise programs, custom orthotic fabrication, management of pain and swelling and wound and scar care.
