Myofascial Release
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].
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.
A tape measure was used to determine the maximum active mouth opening (MMO).
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.
Tragus wall distance measurement was used to evaluate spinal mobility.
The participant was positioned supine for static stretching to be applied to the hamstring muscles
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.
