Abstract: A stretch exercise device is molded in one piece of a material having the physical properties of a soft, flexible, deformable rubber. Two elongate, spaced apart side members extend along a long axis. Many finger grips or rungs are arranged parallel to one another attached at their ends to the side members. The rungs are spaced apart by a distance small enough so that a hand grasping a first rung may reach out with some fingers to reach an adjacent rung without first releasing a secure grip on the first rung. This enables a user to exert continuously increasing tension in stretching exercises. Grooves on the rungs and grooves on the side members provide finger gripping surfaces to facilitate this progressive tensioning movement.

Abstract: A device for treatment of anterior displacement of the vertebrae fits over the hand of the chiropractor. A groovein a first surface fits over the spinous processes and ridges parallel to the groove engage the transverse processes of the patient's vertebrae. The device is positioned immediately below the displaced vertebra and the patient is thrust backward. A second surface of the device engages the treatment table and arrests the backward motion of the normal vertebrae. The anteriorly displaced vertebra continues its backward motion, moving back into alignment with its neighbors. This manipulation is ordinarily performed against the chiropractor's bare hand. This device protects the hand from injury and enhances the performance of the treatment.
