Provided is a walking assist device including a main frame configured to be worn by a user, a power unit mounted on the main frame, a pair of power transmission members for transmitting assist force provided by the power unit to femoral parts of the user and a control unit for controlling an operation of the power unit, wherein the control unit comprises a differential angle computation unit for computing a differential angle between angular positions of the femoral parts of the user about respective hip joints of the user; a differential angle phase computation unit for computing a differential angle phase according to the differential angle; and an assist force computation unit for computing an assist force to be applied to the user according to the differential angle phase.

An elbow harness connected to a forearm harness, the forearm harness supporting a rod driven by a power source, and a proximity detector at a distal end of the forearm harness proximate with where a hand exits the forearm harness when worn. The proximity detector is configured to trigger the power source to drive the rod from a retracted position on the forearm harness to an extended position on the forearm harness.

Methods for providing footwear configured to treat leg length discrepancy include manufacturing a plurality of footwear members. Each footwear member has a sole thickness, with sole thicknesses of the plurality of footwear members spanning a predetermined range of thicknesses. A corrective pair of footwear may be formed by selecting a left member having a first sole thickness and a right member having a second sole thickness, wherein the difference between the first and second sole thicknesses corresponds to an amount of leg length discrepancy to be corrected.

A motion assistance apparatus including a fixing module attached to a user, a driving module fixed to the fixing module to generate rotation power, a supporting module configured to support a portion of a body of the user and driven by the driving module, a sensor configured to measure a width of the fixing module, and a controller configured to adjust the rotation power of the driving module based on the measured width.

A wound dressing material comprising: a wound dressing carrier, N-acetyl cysteine or a salt or derivative thereof, and a stabilized ascorbate. Suitably, the stabilized ascorbate comprises an ascorbate-2-polyphosphate. Also provided are wound dressings comprising the materials, methods of treatment with the materials, and methods of making the materials.

Disclosed are adjustable powered rehabilitation devices and methods for using the same to rehabilitate and/or train a user. The rehabilitation devices preferably have a plurality of selectable power settings that correspond to one or more rehabilitation-oriented actions or functions of the rehabilitation devices. For example, the power of the rehabilitation device may be selected based on a need, ability, muscle-power and/or physiological characteristics of the user. For instance, a rehabilitation device may be operated at a relatively low power setting to allow a patient to use his or her own muscle power when moving with the rehabilitation device. The rehabilitation device may also include an adjustable sensitivity level that corresponds to a user difficulty in triggering a particular rehabilitation-oriented action. The powered rehabilitation device may also temporarily be used to train a user in interacting with a passive or more conventional prosthetic device.

A trouser garment is disclosed. The trouser garment may be a fishing wader. The garment includes a quick-release dropseat to enhance the ease of personal relief, such as a WC break, without completely removing the garment. The garment may include a trouser portion, a bib portion, and a suspension system. A posterior support strap is threaded through a guide, such as a loop, to aid in the mating two ends of a quick-release dropseat buckle. The posterior support strap is coupled to left and right shoulder straps to form the suspension system. The guide and one end of the dropseat buckle are positioned on a posterior surface of the garment. The garment may include cam buckles to enable the adjustment of the left and right shoulder straps and the height of the bib portion. The garment may be worn as a full bib or as a pant.

A method of differentially tuning a lower limb muscle in a human in need thereof is provided. The method includes placement of at least two calibrated, differential disturbances or protuberances under the human's feet thereby tuning a lower limb muscle.

A pre-prosthetic training device is provided. The device provides an interim prosthetic device that aids in the standing, weight bearing, and balancing exercises during post-surgery rehabilitation therapy that are required before a prosthesis fitting. The device includes a residual limb support for receiving the residual limb of an amputee, an adjustable pylon for adjusting the height of the residual limb support, and a support base including a plurality of support legs for providing support to the pylon and residual limb support. The residual limb support includes a cushion having a recessed portion sized to receive the distal end of the residual limb of an amputee and for providing comfort and stability thereto. The residual limb support further includes an upper open end and a sidewall including a tapering portion that provides vertical and lateral access, respectively, of a residual limb into the residual limb support.

A method of differentially tuning a lower limb muscle in a human in need thereof is provided. The method includes placement of at least two calibrated, differential disturbances or protuberances under the human's feet thereby tuning a lower limb muscle.
