Multi-function rehabilitation chair for the lower and upper limbs and muscle exercises. The swinging arm can be used from both sides. Resistance is achieved by applying 4 weights of 2 kg each, 1 weight of 1 Kg and a weight of 0,5 Kg. It is possible to adjust the degree of resistance, exclude a movement and select each segment to be exercised. The 90° backrest can be positioned horizontally by means of servoassisted gas spring with mechanical stop to allow for exercising the limb from a prone position. The legs can be secured with a practical, adjustable padded roll system, while the feet can be secured with an adjustable length strap and fastening clips.
