ABSTRACT:
A hand grip for canes, crutches, walkers, outrigger skis, tools, etc., includes an elongated body possessing an axially inner end provided with a recess configured for partially receiving an elongated cylindrical support member of the ambulation aid, and an axially outer end including an enlarged circular ridge for preventing axial displacement of a user's hand. A mounting post extends axially through the body, transversely securing the hand grip to the support member. An obliquely forwardly and downwardly inclined platform on an upper side of the body adjacent the inner end applies a major portion of the user's weight to the hypothenar muscles of the user's hand. A depression formed axially outwardly of the platform provides a downwardly and axially outwardly curving concave load bearing surface for engagement with thenar muscles of a hand of a user such that the thumb of the user's hand is maintained in a palmar abducted orientation. A palmar arch supporting surface formed on a front portion of the body contiguously with the platform and depression possesses a convex curvature in both circumferential and axial directions. A plurality of axially spaced discrete finger indentations formed in a lower front portion of the body are disposed at an oblique angle with respect to a longitudinal axis of the support member. The platform, depression, palmar arch supporting surface and finger indentations prevent rotation of the hand of a user about a longitudinal axis of the body and maintain the wrist and arm of the user in axial alignment with the support member.
