We built the prototype of the device and made a clinical trial that proved the effecienycy of the system.

The principle of the heel vibrator is that in the supine position with the limb raised and only supported through the heel along with the vibrating motion allows the knee to extend not only through its own weight but due to acceleration produced by the vibrating movement, which results in the loosening of the soft tissue around the knee and decreases the development of flexion contractures. The device is operated with a palmtop and an amplitude lever. The amplitude value can be set between 0,5-3 cm by the lever, and the timing and speed is set with the aid of a palmtop software.
