Abstract: A flexible device having a layered structure for delivering electrical stimulation and one or both of light and ultrasound to a skin surface is provided. The device is flexible so as to form a non-planar contact surface against the skin surface, and includes one or both of (a) a flexible light emitter layer positioned between two flexible conductive layers that emits light when driven by a power source and (b) a flexible ultrasound emitter layer positioned between two flexible conductive layers that produces ultrasound when driven by a power source. The device also includes a flexible electrical stimulation layer that functions as an electrode and is configured to provide electrical stimulation when driven by a power source.

Abstract: A flexible device having a layered structure for delivering light or ultrasound to a skin surface. The device includes a flexible substrate that supports either a flexible light emitter layer or a flexible ultrasound emitter layer, as well as first and second flexible conductive layers. The device has a surface configured to face the skin surface, wherein (a) the light emitter layer emits pulsed light with an intensity that is substantially constant across the device's surface when driven by a power source connected to the conductive layers to thereby deliver a therapeutically effective dose of pulsed light to the skin surface or (b) the ultrasound emitter layer emits ultrasound with an intensity that is substantially constant across the device's surface when driven by a power source connected to the conductive layers to thereby deliver a therapeutically effective dose of ultrasound to the skin surface.

Abstract: A method for exercise, physical therapy and rehabilitation includes providing an elastic member having a tension indicator, securing one end of the elastic member, and stretching the elastic member using a part of the body until the tension indicator indicates that a predetermined tension level has been attained. Upon reaching the predetermined tension level, the elastic member is returned to its relaxed state. The tension indicator on the elastic member may be a printed image of recognizable image that distorts to another recognizable image at the predetermined tension level, a printed non-recognizable image that distorts to a recognizable pattern or image at the predetermined tension level, or an electronic indicator that provides audio and/or visual cues at the predetermined tension level.
