ABSTRACT:
An exercise dynamometer permits a patient to exercise against isodynamic, isokinetic, or isometric resistance to evaluate various musculoskeletal conditions of the patient's human spine. Sensing means are provided to determine the positioning of the patient, and to determine the angular position, velocity, and torque of the exercise movements. In a first embodiment, the patient's head, trunk, upper legs, knees, and feet are secured to a lumbar dynamometer to isolate lumbar and lower thoracic spinal rotation, flexion-extension, and/or lateral bending. During rotational exercise, the axis of movement of the dynamometer is coincident with the patient's spine. In a second embodiment, a patient's trunk and hips are secured to a neck dynamometer to restrict exercise to the cervical spine. The invention facilitates forward flexion-extension, or alternatively lateral bending of the cervical spine, about a first axis aligned with the patient's C1-C2 vertebrae and a second axis aligned with the patient's C7 vertebra.
