Brief Summary

This study aimed to investigate the relationship between latent MTrPs and gluteus medius muscle strength in a group of healthy adults.

Detailed Description

Latent myofascial trigger points (MTrPs) do not cause spontaneous pain; however, they may lead to a limited range of motion and muscle weakness. We hypothesized that latent MTrPs might decrease gluteus medius muscle strength in healthy individuals. Forty-eight healthy men will be included in the study. Trigger point examination for the gluteus medius will be performed bilaterally. Subjects with one or more trigger points on the dominant side and those without any trigger points will be assigned to two groups. Muscle strength for gluteus medius will be assessed with a manual muscle tester using the "break test" technique on both sides. The subjects and the examiners will be blinded. For statistical analysis, the independent sample t-test was used to compare the intergroup differences.

• Observational Model Type: OTHER
• Study Time Perspective: PROSPECTIVE

Study Groups

Group 1. Latent Myofascial Trigger Point Group

24 participants who will be clinically diagnosed with unilateral latent myofascial trigger point in the dominant side gluteus medius muscle.

Muscle strength measurement

Intervention Type: DEVICE

The bilateral gluteus medius muscle strength of each participant will be measured by the assessor (MB) blinded to the participants using the Lafayette manual muscle tester. (Lafayette Instrument Company, Lafayette IN, USA). In the participant's side-lying position, the practitioner applied resistance from the upper ankle to the abduction movement with slight flexion of the upper hip. During the measurements, the participants were asked to perform the maximum isometric contraction for 3 seconds. Gluteus medius muscle strength measurements were repeated three times, one minute apart, on the right and left sides. The mean of the measurements was calculated and recorded

Group 2. Non-Latent Myofascial Trigger Point Group

24 participants who don't have latent myofascial trigger point.

Muscle strength measurement

Intervention Type: DEVICE

The bilateral gluteus medius muscle strength of each participant will be measured by the assessor (MB) blinded to the participants using the Lafayette manual muscle tester. (Lafayette Instrument Company, Lafayette IN, USA). In the participant's side-lying position, the practitioner applied resistance from the upper ankle to the abduction movement with slight flexion of the upper hip. During the measurements, the participants were asked to perform the maximum isometric contraction for 3 seconds. Gluteus medius muscle strength measurements were repeated three times, one minute apart, on the right and left sides. The mean of the measurements was calculated and recorded
