The rest-o-flex™ flexible leg sling is new technology that was designed to improve patient outcome. Rest-o-flex™ is a device that is worn when using crutches, walkers or similar ambulatory devices. Trying to walk on crutches and holding up your leg can be exhausting and may cause back pain as a result of muscle strain and alignment issues. Rest-o-flex™ flexible leg sling allows you to relax your leg muscles by holding up your leg. Rest-o-flex™ employs the revolutionary Poly-Flexx™ Flexible Band Technology which allows flexing at the knee while walking or standing. Exercising your leg against rest-o-flex’s tension bands may aid in blood flow, reduce muscle atrophy and help you recover from your injury.
