ABSTRACT:
An improved thoracic restraint device is provided for use in association with a low back exercise machine adapted for evaluating low back exercise movement against a resistance, particularly rotational movement of the lower back. The restraint comprises a back support having a pair of horizontally extending arms and a pair of flexible restraint straps adapted to be secured across the thorax of the user to the arms so as to secure the thorax of the user against the back support. In order to further limit rotational movement of the thorax during low back exercise, an adjustable back stabilizer is provided beneath the back support and adapted to restrainingly engage the lower thoracic area of the back so as to minimize rotation of the thoracic vertabrae during low back exercise.
