Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To assess the immediate effects of hamstring stretching alone or combined with myofascial release of the hamstring muscle on masseter muscle activity, pressure pain threshold, active mouth opening, hamstring flexibility, and forward head flexed posture in recreationally active participants. The young, healthy, recreationally active adults aged 18-25 years were included in the study. The participants were randomly separated into two groups of equal number. Static stretching alone was applied to one group and this was combined with myofascial release techniques (SSMR) for the other group. Masseter muscle activity was assessed using a NORAXON® surface electromyography device. Both pre-and post-intervention, mechanical pressure algometer was used to measure the pressure pain threshold, hamstring flexibility was evaluated using the maximum hip flexion and active knee extension test, the maximum mouth opening (MMO) was measured with the millimetric ruler, and forward flexed posture was evaluated using the tragus to wall distance test.

Surface EMG Data Collection

For each subject, EMG activity was recorded from the left and right superficial masseter muscles using a multichannel EMG device.The EMG recordings were obtained with three repetitions during mandibular rest, and maximal voluntary isometric contractions (MVIC) in intercuspation (isometry) pre and post-treatment. The EMG data were recorded for 5 seconds, and three trials with 30 seconds of rest between contractions were performed \[Tosato, SENIAM\].

Group Type OTHER

Static stretching

Intervention Type PROCEDURE

The participant was positioned supine for static stretching to be applied to the hamstring muscles. The physiotherapist flexed the participant's hip to the point where resistance to the movement was first observed, with the knee extended.At this point, after waiting for 40 seconds, it was returned to the previous position. This application was made on both sides \[Bretischwerdt\]. The technique was repeated three times, with a 15-second rest interval between each repetition.

Myofascial Release

Intervention Type PROCEDURE

For hamstring muscles, the participants were asked to assume a long sitting position on a firm, flat surface with their arms behind their backs and their body weight on their palms. A foam roller was placed under the hamstring muscles and slowly moved the tuberositas ischii popliteus back and forth with pressure for 4 minutes.

Pressure pain threshold

The pressure pain threshold was measured using a mechanical pressure algometer (model Baseline® Dolorimeters - Fabrication Enterprises Inc) with a contact head of 1 cm2 area.

Group Type OTHER

Maximum Active Mouth Opening (MMO)

A tape measure was used to determine the maximum active mouth opening (MMO).

Hamstring Flexibility

The Maximal Hip Flexion Active Knee Extension (MHFAKE) Test, which is an adapted active knee extension test, was performed to evaluate the hamstring flexibility of the participant.
