Concerning on a Lower Limb Joint Affections Rehabilitation Equipment Command

Abstract:

The aim of the article is to analyze the command of a rehabilitation equipment. The presented rehabilitation equipment allows lower limb joints movements, in order to recover their functionality. The rehabilitation movements are known as continuous passive motion, term used in kinetotherapy.The command used is composed by of a pneumatic muscle supplied with air from a pressure proportional regulator and controlled by a reference module. The reference module, by means of rotary potentiometers, can generate up to six different values of ​​reference voltage which are transmitted as signals to the proportional controller. If no appeal to any of these benchmarks, the transmitted signal to the pressure regulator is a voltage that can be modified by an external potentiometer. The results of experiments shows that proportional pressure regulator allows easy modification of the pressure slope, with better results on rehabilitation movements.
