Hand therapy is typically prescribed for people with hand injuries, a broken hand, carpal tunnel syndrome, arthritis, or other problems that cause them to have diminished strength and range of motion. While the focus is on improving hand function, hand therapy often includes more than the hands and can extend to the wrists, forearms, elbows, and shoulders. https://www.physicaltherapistsnyc.com/physical-therapy-techniques/hand-therapy/
