Abstract: The present invention relates to whole body and spine chiropractic massagers (including retractors), and more specifically, to a whole body and spine chiropractic massager which enables accurate treatment by automatically sensing a target treatment position even if an original treatment n position that was set during the spinal retraction phase has changed, the sensing operation being performed by a sensing part attached to a user's body, or by a sensor installed at a massager or indicator lamp disposed in the bed.

Abstract: Disclosed therein is a muscular strength test system, which can test muscular strength of a specific part of the body in a state where a user binds the body to the frame in safety. The muscular strength test system includes: a controlling part (2); a shaft (4) rotatably connected to a motor (3) via electromotive means (3a); an angle-adjustable frame (5) mounted on an end portion of the shaft (4), the angle-adjustable frame (5) comprising a main frame (5a) adjusting its angle back and forth by the motor (3), and a sub frame (5b) mounted on a motor (6) of the main frame (5a) via a shaft (7); a support frame (5c) vertically mounted on the sub frame (5b); leg binding means (8), hip binding means (9), and head binding means (10) mounted on the support frame (5c) to selectively bind the user's legs, hips and head to the support frame (5c); and sensing means (11) mounted at right and left sides of the sub frame (5b) for sensing muscular strength.
