The intensity of the infrared rays is regulated so as to follow the intensity of the muscular effort proportionally.
The heat, increasing proportionally with the effort exerted by the patient, stimulates the thermoreceptors present on the skin, which are heat – and cold -sensitive receptors that differ from the others in that they are always active, thus constantly informing the brain of the temperature change during the cycle imposed by the machine.

The patient, by visually observing and perceiving the changing intensity of the infrared rays as a function of the effort exerted during movement, will be able to instantly self-assess the success during rehabilitation. This will allow the patient to autonomously control their targeted activity by involving them in the session and motivating them to improve.

In this way, the patient will be able to interact with the intensity of the irradiation depending on the effort exerted by sensorially connecting with the machine, maximising biofeedback, i.e. awareness of the movement being performed.
