Abstract
A manually operated back stretching device may relieve compressive forces of the lower lumbar vertebrae and may safely stretch lower back muscles. The device may include a platform to support a user's lower legs. As the user moves a portion of the device with their arms towards their legs, the forward edge of the platform may rise up and tilt away from the user's torso, causing the user's hips to lift off the floor and stretching the user's back at the same time. As the user moves their arms back over their head, the user's back and legs may relax while the arms are pulled above the user's head. The result may be a back-and-forth dynamic rotational arching motion to repetitively raise the completely relaxed hips and tilt them forward to decompress the spine using appropriate longitudinal and torsion forces at the most pain causing compression points of the lower lumbar vertebrae. The device may safely stretch lower back muscles by incrementally stretching and releasing totally relaxed muscles a relative amount to squeeze out and remove toxic biochemicals from damaged muscle areas unreachable by direct massage.
