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

Study Overview
=================
Brief Summary
-----------------
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.

Masking: Double


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Intervention group for people with brain damage<br>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. | Other: Vojta Therapy<br>* 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.

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 |
