Abstract: A universal hand orthotic device is provided for treating contractures in a patient's left or right hand. The device comprises a bendable metal splint having a central, wrist support region with a hand support region projecting sidewardly from an upper end of the central region. Ears projecting to opposite sides of a lower end of the splint central region are bendable to fit the splint at least partially around a patient's left or right wrist according to intended use of the device. The splint is installed between relatively soft plastic foam pads. The padded splint is received into a padded mitt at least hand regions of which are formed of a smooth, non-irritating fabric. Straps attached to the mitt enable its releasable attachment to a patient's wrist and hand. A plurality of resilient cylinders of increasing diameters detachably attach to a mitt finger-grip region.
