About this study
Official title: Effect of the Muscular Energy Technique With the 4th Ventricle Technique on the Range of Motion of the Hamstring Muscles in Female Basketball Players: RCT
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.
Read the 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).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Simulated techniqueOther
The participant was in a supine position, with her upper limbs at her sides and her neck in a neutral position.
The researcher sat in a cephalic position, making contact with the participant's shoulders, without any movement, until 5 minutes had elapsed.
Muscle energy techniqueOther
The participant was in a supine position, with her upper limbs alongside her body and her neck in a neutral position.
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 flexing the hip and extending the knee passively until the motor barrier was reached, and instructed her to perform an isometric contraction of the hamstrings. She was asked to perform three 7-second contractions with a 2 to 3-second interval, using approximately 20% of her maximum strength, gaining a new motor barrier between each set, for a total of three sets.
4th ventricle technique and muscular energy techniqueOther
The participant was in a supine position, with her upper limbs alongside her body and her neck in a neutral position.
For CV-4, the researcher contacted the squamous portion of the occiput laterally, bringing it close to the posterior convexity of the occiput, bringing the skull into extension, changing the compression movement with decompression, until 3 minutes had elapsed.
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. She then helped the participant to perform the movement, which consisted of flexing the hip and extending the knee passively to the motor barrier, having been instructed to perform an isometric contraction of the hamstring. A total of 3 7-second contractions with a 2-3 second interval were requested, using approximately 20% of her maximum strength, and with a new motor barrier being gained between each series, for a total of 3 series.
| Study group | Role | What they receive |
|---|---|---|
| Control Group | Placebo comparator | 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. Receives: Other: Simulated technique |
| Experimental group MET | Experimental | After completing an individual questionnaire and giving informed consent, the muscle energy technique was performed on the dominant hamstring muscle. Receives: Other: Muscle energy technique |
| Experimental group CV-4 and MET | Experimental | 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. Receives: Other: 4th ventricle technique and muscular energy technique |
What is being measured
The primary outcome is the main question the study is designed to answer.
Altered range of motion of the hamstring muscles.
The universal goniometer is a tool used to assess joint ROM.
Measured: 10 minutes after intervention.

Questions about this trial
What is this clinical trial studying?
A study testing Simulated technique, Muscle energy technique and 4th ventricle technique and muscular energy technique in people with Healthy, run by Natália Maria Oliveira Campelo at 1 site in Portugal.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 30 Apr 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Portugal. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Natália MO Campelo, PhD (+35122 206 1000, nmc@ess.ipp.pt), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Altered range of motion of the hamstring muscles. (time frame: 10 minutes after intervention.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06357611, which also lists 19 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Apr 2024; AzTrials last refreshed its copy on 1 Nov 2026.
