A flexible foot abduction apparatus allowing movement in a horizontal and vertical plane with an elongated member made of a shape memory material. The elongated bar is shaped such that it has both vertical and horizontal aspects to allow a user to more easily manipulate the apparatus in one or both planes. The elongated member has an original shape which can be selectively forced into a second shape by a user and then return to the original shape.

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 fitness tracking system includes a shoe, a magnetometer, and a controller. The magnetometer is mounted on the shoe and is configured to generate three-axis direction data in response to movement of the shoe during a predetermined time period. The controller is operably connected to the magnetometer and is configured to generate two-axis calibrated direction data based on the three-axis direction data after the predetermined time period. The two-axis calibrated direction data corresponds to an orientation of the shoe during the predetermined time period.

Systems, devices and methods for providing active and/or passive compression therapy to a body part can include a compression device worn over a compression stocking. The compression device can have a pulley based drive train that is driven by a motor to tighten and loosen compression elements, such as compression straps, in a precise, rapid, and balanced manner. Sensors can be used in the compression device and/or compression stockings to provide feedback to modulate the compression treatment parameters.

A pain relief device and method or system to aid in the resolution of pain in a body including at least one layer of PVDF film and at least one other layer for directional purposes, as well as a polarizing layer. The device can be packaged in various ways.

An athletic shoe assembly for inhibiting knee and ankle injuries during athletic activities includes a shoe that may be worn during athletic activities. A front cleat unit and a back cleat unit are each positioned on the sole for engaging ground during the athletic activities to enhance traction. Each of the front and back cleat units are rotatably coupled to the sole and the shoe is rotatable about a vertical axis extending through the sole and each of the front and back cleat units. Thus, the front cleat unit and back cleat units inhibit knee and ankle injuries during the athletic activities resulting from a stationary foot and a twisting leg.

A system assesses activity and displays a unitless activity value. A detector senses activity of a user. A processor reads sensed activity data from the detector. A display displays the unitless activity value. An enclosure houses the detector and the processor. The processor periodically reads the sensed activity data from the detector and processes the data to generate an activity number, the number being used to generate the unitless activity value based upon a maximum number and a display range.
