The present invention is a Stretching Machine in the form of a remote power actuated mechanical pushing apparatus comprising a flat base extended in front of an open box frame having a power actuated mechanical pushing and pulling device with a plurality of cylindrical padded arms enabling a full one hundred and eighty degree arc range of effective powered stretching assistance for self stretching the lower back muscles and leg muscles for exercise, physical therapy, rehabilitation, and stretching. It is useful for actively and passively, safely and effectively, self stretching the erector spinae, hamstrings, quadriceps, sartorius, hip adductors, hip flexors, tensor fasciae latae, rectus femris, gluteus maximus, and gluteus medius muscles. The Stretching Machine is also convenient and easy to use to stretch the muscles of the upper back.
A stretching machine apparatus for physical human exercise, comprising a box frame having a base to rest on a surface, said base having a first edge rotatably connected to a first edge of a rectangular panel, and said first edge of said base also rotatably connected to a distal end of an elongated riser such that said panel and riser swing around said first edge of said frame in the same plane, a user variable length push-pull rod having a first end pivotably connected to said riser intermediate said free end and said distal end and a second end pivotably connected to a second edge of said frame distal from said first edge, wherein said riser is urged to rotate from/to proximately parallel to the base of the frame to/from proximately parallel to the panel by a user varying the length of said push-pull rod.
A method of using the stretching machine to stretch a muscle having a connected joint by applying a mechanical force through a range of motion up to 180 degrees of arc about said connected joint enabling the stretching of said muscle without the need to use of any of said muscles associated contracting muscles.
