Exercisers, Flexibility, Upper Limb/Trunk, Inverse Position
Definition : Upper-limb/trunk flexibility exercisers designed to improve the range of motion around a joint by stretching the muscles in the back while the body is in an inverse (i.e., head down) position; they reduce the stress on the back by relieving the gravity compression of the vertebrae. These exercisers usually consist of portable, manually operated inversion tables or chairs and pivot arms, hand grips, and a footrest; some exercisers are powered by a motor to adjust the angles of the inverse rotations. The user usually lies in the supine or, less frequently, the prone inversion position, known as 90/90 inversion position (meaning bending 90 degrees at the knees and 90 degrees at the waist). Inverse position flexibility exercisers are intended to improve the flexibility of the muscles in the back and abdomen, increase muscle strength, and reduce pain and stress on the back.
