A progressive radial correction hand device for correcting ulnar finger deviation in a rheumatoid arthritic hand is described. The device comprises four elongate, soft, flexible finger straps, each of which is least about an inch wide in finger-contacting regions. Distal end regions of the finger straps are attached together to form a finger strap assembly. Described is a flexible fabric hand pad having finger and palm supporting regions and having a padded, hand-contacting upper region. The pad has a thumb-receiving aperture and four generally parallel slits formed in the palm supporting region for receiving, from the under side of the pad, the four finger straps. With the wearer's hand resting on the pad a strap with hook and loop strips attaches the pad to the hand and after the four finger straps are pulled upwardly from the pad over corresponding ones of the ulnar deviated fingers to urge the fingers toward a normal finger position, proximal ends of the finger straps are adjustably attached to distal ends of the straps by hook and loop strips. A stiff pad supporting member may be included and an electric stimulation current of between about 0.1 and 1.0 milliamps may be applied to radial muscle regions of the fingers and thumb of the hand to which the device is attached to strengthen the radial muscles.
