Mechanical Stretch Devices for the Treatment of Joint Stiffness


Mechanical stretch devices are rented durable medical equipment used for joint stiffness due to limited range of motion (ROM) or immobilization. They are intended to elongate the connective tissue surrounding the joint and restore range of motion from prolonged stiffness or contracture due to illness, surgery, or trauma. These devices are controlled by the individual and used in the home as an adjunct to physical therapy.

There are three classifications of mechanical stretch devices currently available:

The lack of randomized control and poor quality of published studies provide little evidence of the efficacy of these devices over traditional therapies.
