Acute Effect of Instrument-Assisted Soft Tissue Mobilization on Hamstring Flexibility Via Fascial Chain

Instrument assisted soft tissue mobilization (IASTM) is one of the methods used to achieve fascial release. In this study, it will be examined whether there will be an increase in hamstring flexibility by releasing the superficial posterior fascial chain as a result of the IASTM technique to be applied over the triceps surae muscle and plantar fascia. Sociodemographic information of individuals who meet the inclusion criteria and volunteer to participate in the study will be obtained, and straight leg lift test and popliteal angle measurement will be performed with the digital inclinometer (Baseline Digital Inclinometer) to be provided within the scope of the project to measure hamstring flexibility. Then, IASTM will be applied to the triceps surae muscle and plantar fascia for 15 minutes. Measurements will be repeated after the application.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Instrument Assisted Soft Tissue Mobilization Group; With the IASTM device, application will be made over the skin to the triceps surae muscle and plantar fascia for 15 minutes. The application will be made in the prone position. Massage oil will be used to reduce tissue friction before the application.	Other: Instrument Assisted Soft Tissue Mobilization; With the IASTM device, application will be made over the skin to the triceps surae muscle and plantar fascia for 15 minutes. The application will be made in the prone position. Massage oil will be used to reduce tissue friction before the application.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Straight Leg Raise Test	Measurements will be made with a digital inclinometer. In the supine position, the digital inclinometer will be inserted into the tuberositas tibia. Then, the participant's leg will be passively lifted by the researcher with the knee extended. The leg will be brought to the point where the tension is felt, where the value on the inclinometer will be recorded. It will then return to the starting position. The procedure will be repeated for both legs.	Baseline

Popliteal angle test	In the supine position, the hip and knee will be brought to 90 degrees. The digital inclinometer will be placed on the tuberositas tibia and the participant will be asked to extend the knee while maintaining the position of the hip. At the last point, the value on the inclinometer will be recorded. It will then return to the starting position. The procedure will be repeated for both legs.	Baseline
