ABSTRACT:
Bed for passive, autopassive or against patient resistance motor re-education, supplied with twenty-one D.C. low voltage (on account of security) electric motors suitable to control respectively eleven mechanical assemblies applied to the bed and suited to cause the different movements of the patient, two further auxiliary mechanical assemblies constrained to the former and at last eight further mechanical assemblies suited to cause the positionings and the adjustments of the bed and of the aforesaid assemblies. It results that the bed is adjustable as height and revolving around their transverse axis. The operation of the motors is servo controlled as speed by speedometer dynamos, as angle shot by angular position circumferentors, as torque by torque detectors, and operated by a microprocessor, so that graduated, soft, constant, stable and repeated movements can be actuated and controlled as type, number, sequence, intensity, amplitude, duration, execution speed, acceleration and stall torque value.
