Abstract: A wireless motion sensor platform comprising MEMS inertial sensors and accompanying software for classification of diverse motion characteristics and kinematics of patient anatomy at high resolution. The sensor platform comprises a low-cost, compact, and low-weight device that can be applied to a patient's upper and/or lower leg during a knee examination to measure acceleration along three axes as well as rotations about these axes.

Abstract: A noninvasive skin-tightening device and method are provided wherein a target line or wrinkle is selected that the patient wishes to minimize or eradicate. The tool has a handle having a proximal end for grasping and a distal end, to which are affixed a plurality of generally parallel spaced-apart blade elements that are oriented generally parallel to the handle. In use a pair of pluralities of lines are scratched in the skin parallel to and one on each side of the target line using the device. The post-treatment steps include cleaning the scratches with antibacterial soap, drying the area, and massaging with antibacterial topical cream. Once the lines scratched in the skin are permitted to heal, the skin is found to be tightened.

Abstract: A noninvasive skin-tightening method is provided wherein a target line or wrinkle is selected that the patient wishes to minimize or eradicate. A pair of lines is scratched in the skin parallel to and one on each side of the target line. Preferably two series of lines are then scratched in the skin, one series parallel to each of the first pair of lines, with a separation of at least 1/16 inch. The post-treatment steps include cleaning the scratches with antibacterial soap, drying the area, and massaging with antibacterial topical cream. Once the lines scratched in the skin are permitted to heal, the skin is found to be tightened.
