Abstract
Spine motion analyzer and method in which a self-aligning measurement linkage is attached to the subject above and below the portion of the spine in which motion is to be monitored. Mounts are provided for attaching the ends of the linkage in fixed positions near the sacrum, beneath the scapulae, and on the head for monitoring either lumbar motion or cervical motion. The linkage has a plurality of arms which move relative to each other in accordance with movement of the spine between the points to which the linkage is attached, and transducers connected to the linkage arms provide electrical signals which can be processed to provide video, printed and/or auditory indications of the spinal movements. One embodiment, which is particularly adapted for sports testing such as golf swing analysis includes a transducer such as a gyroscope which permits measurements to be taken with respect to an absolute or fixed reference such as the ground.
