A foot for a crutch has a ground contact portion with a variable camber. The camber angle changes from at least one of a front edge or rear edge of the variable camber, to a maximum camber. In embodiments, the camber increases from the at least one of the front edge or rear edge to the maximum camber region, and then decreases to the other of the front edge or the rear edge. In embodiments, a foot can have two regions of different cambers laterally disposed from each other such that only one of the two regions contacts the ground during a step at any given time.

Devices for improvement of the basic crutch, cane, and ambulatory aids to provide needed support to ameliorate potential injuries and improve ambulation for persons suffering from injured lower limbs, lumbar region or other injuries, and who frequently require using crutches for mobility. Normally, the conventional crutches require more energy from the user than merely walking, and frequently, a crutch user may require rest. Prior crutch systems have not provided a convenient way to provide the user with such rest. Also, we show crutch support in sitting position that works as a simple and handy decompression system for herniated or bulged discs and injured/weak back muscles. An integrated crutch and walker system is described.

A traction system for an ambulatory support such as a prosthetic foot blade or a crutch includes a sole plate, a latch assembly, and a strap. The sole plate is couplable to a distal end of the ambulatory support to extend under a bottom side of the ambulatory support and a latch assembly. The latch assembly includes a front catch and a rear catch both fixable at a top side of the ambulatory support with the front catch nearer to the distal end of the ambulatory support than the rear catch, and a lever having a front end and a rear end, the front end releasably latchable to the front catch and the rear end releasably latchable to the rear catch when the lever is pivoted about the latched front end. The strap is secured to the lever and to the sole plate.

A suspension walker which may be weighted or unweighted is provided. The suspension walker includes a sole plate having a rocker bottom, a yoke portion and an extension leg attached to the yoke portion. A boot received by a patient's foot is operably coupled to the yoke portion by a first fastener and to an upper portion of the extension leg by a second fastener. An extension leg may be operably coupled at a hinge axis to an upper hinged portion. The hinge axis is configured to be aligned with the knee. A below the knee collar operably and securely couples the boot to the extension leg and the yoke portion. An above the knee collar operably secures the upper hinged portion to the patient's thigh.

The New Design for Crutches and Sitting Device is an improvement of the basic crutch to provide needed support to ameliorate potential injuries and improve ambulation for persons suffering from injured lower limbs, lumbar region or other injuries and who frequently required using crutches for mobility. However, crutches require more energy from the user than merely walking, and frequently, a crutch user may require rest. Prior crutch systems have not provided a convenient way to provide the user with such rest. The current invention fulfills two functions: (i) providing improved walking aid for those recovering from orthopedic surgery of the spine and lower extremities—as well as those who suffer from permanent disability from the spine and lower limbs; and (ii) improved sitting aid for those recovering from orthopedic surgery of the spine and lower extremities—as well as those who suffer from permanent disability of the spine and lower limbs.

In one embodiment, a walking assistance device includes a support member adapted to support a user of the device and a curved tip mounted to the support member, the curved tip including a curved outer surface adapted to contact the ground or a floor surface during use of the device, the curved outer surface having a non-constant radius that changes as a function of angular position along the curved outer surface.

Hands-free walking devices and methods of constructing the same are described herein. The devices can include a receiving member to receive a portion of a patient's leg above a patient's knee and one or more hinges connected to the receiving member. One or more vertical members can be each connected to one of the hinges. A ground-contact member can be connected to the vertical members. The receiving member can transfer at least a portion of the patient's weight through the vertical members to the ground-contact member. The hinges can rotate about an axis about which the patient's knee also rotates while walking to support a natural gait.

The rolling stick is a supporting structure. The rolling stick transfers the load of a patient to a supporting surface. The rolling stick is a rolling structure. The rolling stick operates in a rolling mode and a stationary mode. The rolling stick includes a stanchion structure, a plurality of leg structures, and a caster structure. The plurality of leg structures and the caster structure attach to the stanchion structure. The stanchion structure transfers the load of the patient to the supporting surface. The caster structure rolls the rolling stick across the supporting surface. The plurality of leg structures forms a mechanical structure that: a) forms multiple load paths used for transferring the load of the patient to the supporting surface; and, b) stabilizes the rolling stick from rolling when the rolling stick is in the stationary mode.

A walking assist device includes a vertical support with a proximal end and a distal end, the proximal end coupled to a seat for supporting a user's hip with the user's thigh in a generally horizontal position and a seat attachment member to secure the user's thigh to the seat. The distal end of the vertical support comprises a foot for transferring weight from the user's hip to the ground with the user's thigh in a generally horizontal position. An optional horizontal support extends from the vertical support between the proximal end and the distal end of the vertical support and includes a calf support member.

A traction system for an ambulatory support such as a prosthetic foot blade or a crutch includes a sole plate, a latch assembly, and a strap. The sole plate is couplable to a distal end of the ambulatory support to extend under a bottom side of the ambulatory support and a latch assembly. The latch assembly includes a front catch and a rear catch both fixable at a top side of the ambulatory support with the front catch nearer to the distal end of the ambulatory support than the rear catch, and a lever having a front end and a rear end, the front end releasably latchable to the front catch and the rear end releasably latchable to the rear catch when the lever is pivoted about the latched front end. The strap is secured to the lever and to the sole plate.
