Apparatus for applying a generally dorsally directed force to the palm of a person's hand includes an upper structural support which is structured to be secured in generally overlying relationship with respect to the dorsal region of the metacarpals. The upper support has a base structured to be in contact with the hand and support for straps. A palmar compression pad is structured to be in contact with the palm of the hand with the strap or straps being placed in tension to thereby resist undesired movement of the flexor tendon and thereby reduce median nerve compression in the carpal tunnel. In a first embodiment the upper support will have a base, a pair of apertured towers secured to the base through which a strap or straps may pass and a suitable structure for fastening the strap or straps to the upper support. The strap or straps will preferably be adjustably and removably securable to regions adjacent the ends of the palmar compression pad. A bridge may be provided between the upper support towers for facilitating securing the strap or straps thereto. In another embodiment of the invention, the bridge and towers are eliminated. The palmar compression pad is generally rigid and has a pair of generally upwardly extending legs through which one or more straps pass with the upper support secured to the strap. The strap is placed in tension in order to provide the desired dorsally directed force to the palm of the user's hand. Related methods are provided.

[ What is claimed is:] [1.]1. A hand orthosis for applying a generally dorsally directed force to the palm of the hand comprising:(a) an upper support structured to be in contact with an upper surface of the hand opposite the palm of the hand and secured in overlying contacting relationship with respect to the dorsal region of the metacarpals;(b) a generally rigid unitary palmar compression pad structured to be in contact with the palm of the hand, the palmar compression pad having a pair of strap engaging ends and an irregular contoured surface sized and configured to generally complement the shape of the central region of the palm; and(c) flexible strap means secured to said palmar compression pad and to said upper support for applying the dorsally directed force solely to the palmar region of the hand and not the wrist, whereby said orthosis is sized and configured to only apply said dorsally directed force to the central palmar region of the hand thereby maintaining the flexor tendon in a desired dorsal position. [12.]12. A method of reducing median nerve compression in the carpal canal comprisingproviding a palmar compression pad positioned on the back surface of the hand and an upper support with strap means supported by said upper support and adjustably secured to said palmar compression pad,said palmar compression pad being generally rigid, positioning said palmar compression pad in intimate contact with the palm of the user, andsecuring said strap means in tension to said palnar compression pad and said upper support to thereby cause a generally dorsally directed force to be applied to said palm whereby the dorsally directed force reduces the median nerve compression in the carpal canal.13. The method of claim 12 includingsecuring said strap means to an upper side of said upper portion.14. The method of claim 13 includingemploying hook and loop fasteners to secure said strap means to said upper support.15. The method of claim 12 includingemploying as said strap means a strap having end portions secured to other portions of said strap with said strap in tension.16. A method of reducing median nerve compression in the carpal canal comprisingproviding a palnar compression pad positioned on the back surface of the hand and an upper support with strap means supported by said upper support and adjustably secured to said palmar compression pad,said palmar compression pad being generally rigid,positioninig said palnar compression pad in intimate contact with the palm of the user,securing said strap means in tension to said palmar compression pad and said upper support to thereby cause a generally dorsally directed force to be applied to said palm,securing said strap means to an upper side of said of upper support,employing hook and loop fasteners to secure said strap means to said upper supportproviding said palnar compression pad with a pair of generally upwardly extending legs having strap receiving openings, andpassing said strap means through said openings and securing said strap means in tension.17. The method of claim 16 includingsecuring said strap means to said upper support by hook and loop fasteners.18. The method of claim 17 includingemploying as said upper support a flexible, compressible pad.
