Summary

This randomized controlled trial aimed to compare the immediate effects of two self-myofascial release techniques-suboccipital muscle inhibition and thoracolumbal fascia inhibition-on hamstring flexibility, spinal range of motion, and balance in healthy adults. A total of 75 participants with hamstring tightness were randomly assigned to one of three groups: suboccipital inhibition, thoracolumbal inhibition, or control. All participants performed hamstring stretching, and the intervention groups received one of the inhibition techniques immediately after. Outcomes were measured at baseline and within 30 minutes post-intervention. The study found that both techniques led to significant improvements in hamstring flexibility and spinal mobility, with region-specific benefits. The thoracolumbal technique was more effective for trunk and hamstring flexibility, while the suboccipital technique provided greater cervical mobility gains. Balance improvements were limited. These findings support the use of targeted myofascial interventions in clinical practice.

Conditions

  • Healthy Individuals With Hamstring Tightness

Interventions

OTHER

Thoracolumbar fascia inhibition

Soft tissue mobilization: Participants will be asked to lie on their backs without a pillow in a hook-lying position, placing a foam roller under the inferior part of the scapula and clasping their hands behind the cervical region. Then, they will be instructed to lift their hips off the ground and roll the foam roller in a cranial and caudal direction from the inferior scapular region to the sacral area for 30 seconds, performing flexion and extension movements with their knees. This application will be performed in a total of 4 sets.

OTHER

Suboccipital inhibition group

Soft tissue mobilization: Participants will be asked to lie in a supine position on an appropriate surface and keep their knees in extension. Then, they will be instructed to hold both ends of a sheet and place the middle part of the sheet on the plantar surface of one foot. Using the sheet and by dorsiflexing the ankle, they will pull the extended leg toward themselves. This position should be maintained for 30 seconds (8). It is important that the opposite knee does not flex during the exercise. The application will be performed bilaterally.

OTHER

hamstring stretching

Participants performed passive hamstring stretching using a sheet for self-assistance. Participants will be asked to lie supine on an appropriate surface and keep their knees in extension. Then, they will be instructed to hold both ends of a sheet and place the middle part of the sheet on the plantar surface of one foot. Using the sheet and performing ankle dorsiflexion, they will pull the leg-kept in knee extension-toward themselves. This position should be held for 30 seconds (8). It is important that the opposite knee does not move into flexion during the exercise. The application will be performed bilaterally.
