• Lead Sponsor: Natália Maria Oliveira Campelo

Brief Summary

It is known that there are studies that prove the effectiveness of muscle energy techniques and the fourth ventricle technique separately, however, information is scarce regarding the combination of the two and their effectiveness in the population. The aim of this randomized controlled study is to compare the immediate effects of the techniques compared to the muscle energy technique alone in female basketball players.

Detailed Description

The muscular energy technique (MET) is a manual therapy technique that uses isometric contractions with the aim of increasing the extensibility of the muscle group, as well as promoting lymphatic and venous circulation. The fourth ventricle technique (CV-four) plays an amplifying role in the movement of tissues and fluids, restoring the flexibility of the autonomous response. For the MET, the researcher adopted a position homolateral to the dominant limb, contacting the lower limb with the caudal hand in the region of the malleoli. He then helped the participant to perform the movement, which consisted of flexion of the hip and extension of the knee passively until the motor barrier was reached, after which she was instructed to perform an isometric contraction of the hamstring. A total of three contractions of seven seconds with an interval of two to three seconds were requested, using approximately twenty per cent of their maximum force, and gaining a new motor barrier between each series, for a total of three series. For the CV-four technique, the researcher adopted a seated position and laterally contacted the scaly portion of the occiput, bringing it closer to the posterior convexity of the occiput, bringing the skull into extension, changing the compression movement with decompression, until three minutes had elapsed. At all stages of the session, the participant was positioned in the supine position, with the upper limbs alongside the body and the neck in a neutral position. All the participants in the study underwent an initial and final assessment protocol to determine their range of motion (ROM).

Arm && Interventions

Group	Intervention	Description
Control Group	Simulated technique	After completing an individual questionnaire and giving informed consent, a placebo technique was performed, consisting only of contact in the area of the participant's shoulders.
Experimental group MET	Muscle energy technique	After completing an individual questionnaire and giving informed consent, the muscle energy technique was performed on the dominant hamstring muscle.
Experimental group CV-4 and MET	4th ventricle technique and muscular energy technique	After completing an individual questionnaire and giving informed consent, the 4th ventricle technique (CV-4) was performed, followed by the muscle energy technique on the dominant hamstring muscle.

Primary Outcome Measures

Name	Time	Method
