Hip rotation measuring device with an accelerometer, a micro-controller, a printed circuit board, a memory chip, a power supply such as batteries, an on-off switch, a start-stop recording switch, an acceleration direction switch an audible sound generator, a readout display such as an LCD display, standard support electronics such as resistors capacitors and regulators for operating the electronic components, a case to house the components, and a belt clip or other standard attachment device fixed to the outside of the case so that when the components are combined within the case and when the case is attached by the clip to an article of clothing that is in close proximity to a moving body part such as a hip, the readout display can show magnitude of acceleration or deceleration of hip movement of the user. The device can measure other body part acceleration and deceleration such as hand, foot, shoulders.
