Study summary

A 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.

Interventions

  • OtherVojta

    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.

  • OtherControl

    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.

What researchers measure

Primary outcomes

  1. Electromyographic activity in abdominal muscles

    The electromyographic activity of internal and external obliques in nanovolts will be collected before, during and after the intervention.

    Time frame: Change from Baseline electromyographic activity at 7 minutes.

Secondary outcomes

  1. Date of birth

    It will be registered at the beginning of the study in order to calculate the age of the participant.

    Time frame: Baseline

  2. Sex

    It will be registered at the beginning of the study.

    Time frame: Baseline

  3. Height

    It will be registered at the beginning of the study in centimeters.

    Time frame: Baseline

  4. Weight

    It will be registered at the beginning of the study in kilograms.

    Time frame: Baseline

  5. International Physical Activity Questionnaire

    It will be measured at the beginning of the study to quantify the level of physical activity of the participant. This validated scale allows you to determine if you have a low, moderate or high physical level.

    Time frame: Baseline
