A shock absorbing ferrule for a shaft of a crutch, an elbow/forearm crutch, a walker and other devices used during assisted ambulation, wherein the shock absorbing ferrule mitigates impact, potentially reducing injury during their use. The shock absorbing ferrule includes a ferrule having a viscoelastic walled cylindrical socket, which is an annular longitudinal cavity fitted with a shock absorbing assembly. The shock absorbing assembly includes at least one compression spring and a push plate. The compression spring has an outside diameter that is less than the inside diameter of the socket and is seated on the metal distribution washer and under the push plate. The push plate is a metal disk with a smooth perimeter edge having an upper side that is in abutment with an end of the shaft and a lower side that is in abutment with the compression spring.

An embodiment includes a walking stick. The walking stick includes a rod assembly, a water purification assembly, and a manual pump. The rod assembly extends from a first end to a second end that is opposite the first end along a longitudinal direction of the rod assembly. The rod assembly includes at least one rod portion. The water purification assembly is integrated with the rod assembly. The manual pump is configured to impose a pressure gradient in the water purification assembly. The manual pump includes a plunger that is physically coupled to a handle portion. Motion of the plunger relative to the water purification assembly draws water into an inlet tube that is positioned in the rod portion and through the water purification assembly. The motion of the plunger results from translation of the handle portion in substantially the longitudinal direction of the rod assembly.

A walking cane may be transformed into an assistive device for sit-to-stand transfers. The device has two sets of opposing handles, which are to be grasped by the user and an assister during sit-to-stand transfers. The transformation is accomplished by deploying a second set of handles by pivoting or rotating from a stored to a utility position. The assistive device form can then be reversed by the user once standing by reversing the deployment.

A foot for a medical mobility device includes an upper portion, a traction surface, and a cushion ring. The upper portion has an opening at a first end for receiving an end of a medical mobility device and an upper portion post extending from a second end away from the opening. The traction surface has a core element comprising a cylindrical post extending upwardly from the traction surface. The upper portion is secured atop the core element. The cylindrical post is adhered to the upper portion post thereby defining a space between the upper portion and the traction surface, and the cushion ring is positioned in the space.

Walking assistance devices and systems for rehabilitation system for reducing the knee adduction moment in a user, reducing stress on the knee, and potentially slowing deterioration of the knee associated with osteoarthritis of the knee and delaying the need for knee replacement surgery. In one embodiment the walking assistance device includes a handle or grip portion, a shaft portion, and a base portion having a rocker bottom which reduces the knee adduction moment on the stance leg of a user.

Mobility assistive devices in the nature of canes, staffs or walking sticks are constructed with a bent or “dog-leg” shape so that an upper portion of the cane adjacent the handle extends forward in the direction of travel of the cane's user and is visible in her peripheral vision. The shape of the cane and the proprioceptive feedback from its motion convey more information to the user and allow more confident, efficient motion than a traditional straight cane or staff. Some embodiments include rotating joints to allow the cane to be folded when not in use.

A shock-absorbing cane tip apparatus for user comfort and improved cane tip longevity includes a tip base having a base top side, a base bottom side, and a base perimeter. A tip sidewall is coupled to the tip base. The tip sidewall has a sidewall outer face, a sidewall inner face, and a sidewall top rim. The sidewall inner face defines a cane cavity to slidingly receive a tip end of a cane. A bottom plate is coupled to the tip base within the cane cavity. A compression spring is coupled to the bottom plate and is oriented perpendicular to the base top side. A top plate is coupled to the compression spring and engages a distal end of the tip end of the cane to compress the compression spring when weight is pushed onto the cane.
