Therapeutic apparatus having a frame that includes a pair of laterally spaced A-frames in part defined by a user's seat extending therebetween and seat supports. A pair of independent tubular guides are connected to the apices of the A-frames for pivotal movement about aligned transverse axes, and each of the guides has an elongated and resiliently extensible operating element reciprocably extending therethrough that is provided at its forward end with a laterally extending handle and at its rear end with a laterally extending and spring-mounted roller that is engageable with the user's back upon the user urging the operating element forwardly in its guide. Rocking of a guide and its element in a vertical plane by the user manipulating the associated handle causes the associated roller to roll up and down against the user's back. A foot operable crank is mounted at a position below and forwardly of the seat to enable the user to exercise his legs while exercising his arms and shoulders to massage his back.
Therapeutic apparatus comprising a frame, a pair of laterally spaced guide means pivotally mounted on the frame for vertical swinging movement about aligned horizontal axes, an elongated element operatively associated with each of said guide means to be guided by the latter for longitudinal reciprocation relative thereto, each of said operating elements having forward and rear ends with a handle fixed to the forward end, and each of said operating elements being provided at its rear end with a back massaging means that is laterally offset toward the other operating element, whereby a forwardly facing user positioned between the laterally spaced guide means can manipulate the handles to cause the massaging means to contact his back with a manually controllable force while moving upwardly and downwardly thereagainst.
