A leg attachment assembly for a stilt device of the type used to support a user above a base surface. The leg attachment assembly has a curvilinearly extending leg band configured to partially surround an upper leg portion of a user's leg. The leg band is attached to a distal end of a support pole using a pair of spacers and associated fasteners. One or more strengthening ribs extend in a lateral direction between contact locations of the spacers. The strengthening ribs extend beyond the spacers to enhance rigidity of the leg band during use. A securement strap can be used to encircle the user's leg and the leg band to attach the stilt to the leg. The strap can be routed between the spacers and over the top surfaces of the strengthening ribs so that, when the strap is tensioned, the ribs prevent slippage or displacement of the strap.

Height-adjustable apparatus using a spring to urge forward and rearward undulating whippy locomotion. A hand-crawling embodiment enables users to engage in all-fours crawling locomotion while the body is conventionally situated in a two-legged orientation. A foot-bounding embodiment enables walkers, joggers, runners and jumpers to engage in forward and backward whippy locomotion. A crutch embodiment enables crippled or injured users to likewise engage in whippy locomotion.

Stilts such as for use by a worker at a work site. Each stilt comprises a leg support, a shoe platform, a floor platform, a riser disposed between the shoe platform and the floor platform, and side supports, wherein each side support is connected to the leg support, the shoe platform, and the riser, wherein the stilt provides rigidity to the shoe platform without having to employ springs. Preferably, the riser is easily removable such that a different size riser can be used if a different level of elevation is desired, i.e., given the user's height and the height of the work to be performed. As such, the stilts are easily adjustable with regard to height. Additionally, preferably at least one or more other components of the stilts, such as the floor platform, is easily replaceable as well.

Provided are apparatuses for augmenting human speed, human-driven compliant mechanisms, artificial limbs to augment human movement, and the like. The apparatuses can include variable stiffness mechanisms including springs that can be configured to selectively store and subsequently release energy generated by human movement. The apparatuses can selectively release the captured energy supplied by the human to provide force and power output beyond the physical capability of the human.
