VERTEBRAL ACTION ANALYZER AND ANALYSIS METHOD

摘要

PURPOSE: To monitor vertebrae movement to impart biodynamical evaluation by attaching self-aligning measuring link devices to a subject at the top and bottom of the vertebrae. CONSTITUTION: A pelvis mount 43 is attached to a subject, a belt is wound around the buttocks, and a mounting column 48 is aligned with the sacrum. A thorax mount 44 is mounted, a thorax strap is wound around the part of the trunk immediately below the scapulae, and a mounting column 59 is aligned with the vertebrae. A converter 34 imparts a signal corresponding to the axial rotation of the lumber vertebrae, converters 35, 36 impart signals corresponding to the horizontal bending of the lumber vertebrae, and converters 37-39 emit signals corresponding to the elongation and bending of the lumber vertebrae. The signals produced by the converters are processed to impart information about those ranges and the moving speed of the lumber. By simultaneously monitoring all the vertebrae, complete biodynamical evaluation of the vertebrae movement can be obtained, and data from different tests can be used in comparative analysis.
