Breathable residual-limb system that admits air and allows sweat to evaporate from the surface of the residual limb. In an embodiment, the system comprises a liner sock to be worn on the residual limb, and comprising air-permeable textile forming a substantially cylindrical portion that is closed on a distal end and open on a proximal end and comprising an internal surface and an external surface. The liner sock further comprises a friction-interface material that covers only a portion of the internal surface of the air-permeable textile, such that, when worn on the residual limb, the friction-interface material contacts a surface of the residual limb, and an uncovered portion of the air-permeable textile which the friction-interface material does not cover allows air to pass between an external environment of the liner sock and the surface of the residual limb.

Breathable residual-limb socket system

Disclosed herein are devices, systems, and methods for measuring socket fit in lower limb prostheses and detecting motion of a residual limb relative to a prosthetic socket. Also disclosed herein are methods for developing a socket-fit detection system for sock management that can be applied to adjustable socket systems.

An exercise machine has a mobile base and an upright support extending upwards from the mobile base. An upper support assembly extends forward from an upper portion of the upright support and an exercise device is suspended from the upper support assembly at a location spaced forward from the upright support. The exercise machine may include a compact and safe counterbalancing gas spring mechanism that tends to move the exercise device away from the exerciser, and that requires a force to be applied to move an exercise device down towards the exerciser. The exercise machine may include an exercise device that is rotatable along a vertical axis, and may be coupled to an adjustable monitor for a wide range of uses. The exercise machine may be used by a exerciser lying supine, sitting in a chair or wheelchair, or standing in front of or adjacent the exercise machine.

Exercise machine

An exercise machine has a mobile base and an upright support extending upwards from the mobile base. An upper support assembly extends forward from an upper portion of the upright support and an exercise device is suspended from the upper support assembly at a location spaced forward from the upright support. The mobile base has caster wheels and can be positioned from either side of a bed so as to extend partially under a bed with the upright support located on one side of the bed and the exercise device suspended over the bed in a position accessible by a patient lying supine in the bed for performing exercise. An anchoring system resists movement of the base for stability when exercise is performed.

Exercise machine and method for use in a supine position

A care unit can include a base member and a plurality of petal members. Each petal member can extend from a first end, engaged with the base member, to a second end, spaced from the base member. Inward-facing surfaces of at least two petal members and the base member can collectively define a cavity for receiving at least a portion of the patient. The care unit can further include one or both of a therapy component, configured to provide a treatment to the patient, or a sensor component, configured to monitor a condition of the patient. The therapy component can be coupled to, or integrated with, one or both of the base member or a petal member and can include an optical light source, a thermal energy source, an oxygen or air source, a sound wave source, a sound wave-cancelling source, or a pulsating source, for example.

The present invention relates to a novel approach means of screening various skin surfaces, including hard to reach areas of the human body, as well as more commonly seen areas such as the foot. The present invention can help patients, especially those who are immobile or those with diabetes self-monitor and transmit the skin condition accurately, so that medical providers may assess the risk or presence of skin tissue breakdown. Thus, provision is made for a remote screening device that can be used in telemedicine or home self-monitoring approaches and offers high resolution image, without artifacts or other distortions that might arise from images taken of feet that have been compressed through standing and the like.
