Abstract In the paper, a new type of a rehabilitation system for knee and ankle is
represented that integrates a vibration system which allows a faster recovery and has
a beneficial action on the bones, muscle and nerves, which is a well-known treatment.
The system will be used as an ambulatory system for home use and must be cheaper
and easy to manufacture. The system has a special design using tubes connected
hydraulically. Two main possibilities were considered to transmit the vibration to
the leg. The first is based on filling the tubes with a liquid, and using vibration
transmission through liquid the vibration energy is transmitted to an elastic part
of the frame, supporting the leg. The second method is using a vibration-exciting
additional device, using an electrodynamic exciter to transmit the vibration.
1 Introduction
There are numerous experimental evidences made on both animal models and
people demonstrating that mechanical vibrations increase the regenerative potential
of muscle tissue [1–3].
In this paper, we present a new medical rehabilitation system for knee and ankle
in which we can integrate a vibration system, at the final element, that is designed to
shorten the time of recovery of users or for other medical purposes. This system is
mobile and can be used both outdoor and in personal dwellings. Numerous medical
clinical trials [4–7] have shown that the inclusion of vibrations in the process of
medical recovery shorts the period of rehabilitation, but their vast majority is focused
