A unique model which graphically illustrates the effect on the spine of a bad lifting posture. The figure will raise a weight from either of two clearly marked positions. If the correct position is used the spine is not distorted. The incorrect posture causes obvious distortion to the spine. The base incorporates anatomical illustrations of the effect upon the spine and a background booklet is provided. 23x15x15cm.
