Apparatuses and methods for preventing and / or treating
carpal tunnel syndrome are disclosed. One such apparatus comprises a splint for wearing on a portion of an upper extremity of an individual, a warning mechanism carried by the splint and a switch mechanism carried by the splint and electrically coupled to the warning mechanism. The switch mechanism is operable to activate the warning mechanism upon extension or flexion of the hand beyond a predetermined
range of motion and thereby alert the user of such undesirable motion of the hand.
