ABSTRACT:
A back muscle exercising and stretching apparatus comprises a stationary seat upon which a user may sit, a backrest movably attached to the seat, and a resistance means, such as a hydraulic or pneumatic spring, movably attached to the seat and the backrest to define the force required to move the backrest relative to the seat. The user may sit either facing toward or away from the backrest and then bend either forward or backward to cause the backrest to move from a substantially vertical position to a substantially horizontal position. Higher resistances may be used to effect exercise and lower resistances may be used to effect stretching. The apparatus may be placed in a convex table-like orientation such that the user may lay face up thereon to effect stretching of the back muscles. An optional headrest increases comfort and permits the patient to exercise and stretch portions of the upper back and neck.
