Self-operated traction machine uses series of hinged levers operated by pull-down handle to raise knees and stretch lower back

摘要

The user lies on his back and inserts his legs between the handle (11) and the knee support roller (12). He then fits his feet under the rear ankle trap roller (14). He then pulls downward on the handle (11). This action pulls the knee support upwards, lifting the base of the spine from the floor and applying traction.
