The present invention relates to an assisted rehabilitation system comprising a device with static-bicycle movement, and devices that automatically sense and manipulate body performance parameters, allowing the rehabilitation response process of a user to be optimised. In particular, the sensing devices measure the pedalling rate, the pedalling resistance and the user's pulse rate, allowing the optimum exercising range to be configured, depending on the data acquired from the patient and on the level of effort required from him or her. The system also comprises two motors. One motor drives a flywheel that allows the user to experience a variation in the pedalling rate while using the device. A second motor provides different levels of pedalling resistance, allowing muscular strength to be developed. When starting the activity, the user enters, on a touchscreen, the preliminary parameters for the desired pedalling rate and resistance level, which are analysed by a processing unit that calculates a suitable rehabilitation plan.
