An ergonomic collapsible crutch for providing assistance with ambulatory movement of a user, the crutch including a supporting member having an underarm support surface and a hand grip portion, a gripping pad disposed remotely from the underarm support surface generally along a vertical axis and connected to the supporting member to provide stability and grip on surfaces of a walking environment, and a hand grip attached to the hand grip portion of the supporting member so that the handgrip extends from the supporting member at an angle from the vertical axis ranging from about 85�� to about 60�� and from about 95�� to about 120��. The ergonomic collapsible crutch may also include a shock absorbing device and buttons for adjusting the height of the crutch as well as the position of the hand grip. The hand grip may also be ergonomically contoured for improved use by a user.

The invention claimed is: 1. A shock absorbing crutch, comprising: a proximal end and a distal end; a vertical axis; a supporting member having a proximal end and a distal end, the supporting member comprising: a generally horizontally oriented underarm support, the underarm support having a concave curvature along its top edge and a convex curvature along its bottom edge; a stabilizing portion, the stabilizing portion extending downwardly from said horizontal underarm support at an angular orientation with respect to the underarm support in the range of 45�� to 135��; a middle bend portion projecting toward the vertical axis such that the middle bend portion is at an angular orientation with respect to the stabilizing portion in the range of 90�� to 180��; and a generally vertically oriented hand grip portion, the hand grip portion containing a plurality of diametrically opposed apertures; a hand grip attached to the handgrip portion of the supporting member; a generally vertically oriented alignment rib having a proximal end and a distal end; a folding section connecting the distal end of the supporting member to the proximal end of the alignment rib so that the crutch is foldable; a generally vertically oriented adjustable portion, the adjustable portion having a proximal end and a distal end; a shock absorbing device located within the distal end of the adjustable portion; and a gripping pad; wherein the hand grip attached to the supporting member such that is extends outwardly and downwardly from the supporting member at an angle ranging from about 10�� to about 30�� below horizontal. 2. An ergonomic crutch, comprising: a supporting member, wherein the supporting member has a proximal end, a distal end and a hollow interior, wherein the supporting member is configured to provide: a generally horizontally oriented underarm support at the supporting member proximal end, the underarm support having a concave curvature along its top edge and a convex curvature along its bottom edge, the underarm support having an underarm support pad fabricated of elastomeric material, a stabilizing portion, the stabilizing portion extending downwardly from said horizontal underarm support at an angular orientation with respect to the underarm support in the range of 45�� to 135��, a middle bend portion projecting toward the crutch distal end such that the middle bend portion is at an angular orientation with respect to the stabilizing portion in the range of 90�� to 180��, a generally vertically oriented hand grip portion, wherein the hand grip portion is at the distal end of the supporting member, the hand grip portion containing a plurality of diametrically opposed apertures a hand grip attached to the supporting member; and a hand grip extending outwardly and downwardly from the supporting member at an angle of at least about 10�� below horizontal such that the wrist of a user is generally maintained in a neutral position wherein the user's third metacarpal is generally aligned with the user's radius. 3. The ergonomic crutch of claim 2, wherein the hand grip is adjustable. 4. The ergonomic crutch of claim 2, wherein the crutch further comprises a folding section.
