Electromyographic Control of the Response in the Application of Vojta Therapy in People With Brain Injury. (ElectroVojta)

A non-randomized clinical trial on a cohort of healthy subjects of legal age, both sexes, recruited from the university community and who will be randomly distributed into two groups (experimental and control). The objective will be to determine the feasibility of the standardized intervention protocol on the stabilizing muscles of the trunk (external oblique and internal oblique) before, during and after the application of Vojta Therapy, and to know the effects produced on the Musculature studied after performing the intervention.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Intervention group for people with brain damage; Other: Vojta 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 therapy consists of the application of a stimulating pressure in the pectoral area in the pattern of the locomotion complex of reflex rolling in its first phase. 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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Electromyographic activity in abdominal muscles	The electromyographic activity of internal and external obliques in nanovolts will be collected before, during and after the intervention. Acquired signals are sampled at 1 KHz and filtered with a 60 Hz high pass digital filter to reject signals of non-muscular origin. The degree of muscle activation measured in micro volts (uV) will be recorded.	Change from Baseline electromyographic activity at 10 minutes.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Date of birth	It will be registered at the beginning of the study in order to calculate the age of the participant.	Baseline
Sex	It will be registered at the beginning of the study.	Baseline
Height	It will be registered at the beginning of the study in centimeters.	Baseline
Weight	It will be registered at the beginning of the study in centimeters.	Baseline
