Abstract: A method and apparatus for monitoring posture deficiencies in the spine and including a flexible body (30) encapsulating a flexible operating arm (31) cantilevered from a base moulding (34). The operating arm (31) is provided with upper (37) and lower (40) strain gauges bonded to the upper and lower faces respectively of the operating arm (31) at the point beyond the stiffening base moulding (34) to ensure that differential strain is experienced on deflection of the operating arm (31). Wire tails (41) are terminated as a PCB assembly (45) mounted to the printed circuit support (35), which assembly comprises a PC board bearing an LSI processor (46), rechargeable battery (47), vibrating motor (50) and inductive coil (51) selected to fulfil the functions of transmitting and receiving element, and inductive power supply for charging the battery (47), under the control of processor (46).

Abstract: A method and apparatus for assessing the function of deep joint stabilizing muscles. Superficial muscles are monitored using an EMG (3) during performance of an activity known to require recruitment, primarily, of deep stabilizing muscles when performed correctly. If the deep muscle functions adequately, there is little activity of the superficial muscles. Conversely, if the deep muscle function is inadequate, the superficial muscle activity is increased. Monitoring of the superficial muscles may be combined with monitoring of the deep joint stabilizing muscle using ultrasound imaging (12) and/or pressure biofeedback. The apparatus includes an EMG unit (3) ultrasound unit, pressure biofeedback unit (16) and vitalograph (9), in combination with a computer (5) programmed to analyze data from them and given an indication of function.
