The subject will be placed on a stretcher with the torso uncovered. Once the spectroscopy helmet is in place, a recording of the resting activity will be started, two minutes of stimulation (digital pressure), one minute of rest, two minutes of stimulation on the contralateral side and, finally, one minute of rest.

The therapy consists of the application of a stimulating pressure on the pectoral area in the pattern of the reflex swing locomotion complex in its first phase. For this, the subject will be placed in supine decubitus aligned with respect to the axial axis, with the arms alongside the body, the lower extremities in extension and the head extended with a rotation of approximately 30º to one side of the stimulation. Manual stimulation pressure will be exerted in the space between the 6th-7th or 7th-8th ribs below the mammary line, with a force of about 2 kg.

The subject will be placed on a stretcher with the torso uncovered. Once the adhesive electrodes have been placed in the different recording areas on the anterior part of the trunk, a recording of the activity at rest will begin, two minutes of stimulation (digital pressure), one minute of rest, two minutes of stimulation in the contralateral side and, finally, one minute of rest.

The control group will receive an application in an area with low receptor density located on the thigh, with a force of about 2 kg

For this, the subject will be placed in a supine position aligned with respect to the axial axis, with the arms along the body, the lower extremities in extension, and the head extended with a rotation of approximately 30º towards one side of the stimulation. The manual stimulation pressure will be exerted in the space between the 6th-7th or the 7th-8th rib under the mammillary line, with a force of about 2 kg.
