  • Butterfly chair stretching apparatus
    Patent number: 4949960
    Abstract: A stretching apparatus for stretching leg and hip muscles and increasing rotation of the leg in the hip joint of a human user. Flexible straps attach two body support platforms to a frame. Movement of one of the body support platforms to a reclining position against the force of the straps forces the knees of a user outward, thus stretching the leg and hip muscles and causing the legs to rotate in the hip joints, increasing flexibility in the joints.
