<p>A self contained portable traction or back-stretch apparatus (11) comprising a frame assembly (13) with first tensile force application means in the form of two U-shaped members (15) for supporting a person under their arms, and a second tensile force application means (17 or 57) for supporting a person about their waist and hips. The frame assembly (13) is formed of two frames (19) comprising parallel elongate struts (21) and parallel elongate struts (23) connected about a pivot pin (25) in a scissor type relationship. Separation of the force application means (15 and 17 or 57) is limited by a resiliently stretchable mat (37) which also serves to support the weight of a person therebetween. The weight of the person supported in the traction apparatus results in a downward force on the frame assembly (13) which translates to a tensile force applied between the force application means (15 and 17 or 57) and effects traction, providing a degree of intervertebral separation in the person.</p> |
