Clinical Trial Summary
Background and aim: Percussion massage, which is one of the applications to increase muscle
flexibility, is a method that combines vibration and massage therapy elements. With its
popularity in recent years, it is offered as an alternative to traditional methods that
increase flexibility. The aim of this study is to examine the acute effect of percussion
massage and static stretching exercise on hamstring flexibility.
Method: Individuals with active knee extension angle limited to at least 15 degree were
included in the study, which was designed as a cross-over. Active Knee Extension test and Sit
and Reach Test were performed before and after the interventions for the evaluation of
hamstring flexibility. Participants were divided into 3 groups as percussion massage, static
stretching and control groups, interventions were made with 3 days intervals and control
measurements were taken.
Description:
Active knee extansion test: In this test, which is used to evaluate hamstring flexibility in
the sitting position, the participant was asked to sit on the edge of the bed and the
hip-knee flexion angle was adjusted to 90 degree. For the measurement of active knee
extension degree, a double-arm universal goniometer (Baseline Stainless Steel Goniometer;
Fabrication Enterprises Inc., Elmsford, NY, USA) was placed on the lateral condyle of the
femur and the participant was told to actively extend the knee to full extension. The angle
at the end point of the movement was recorded.
sit and reach test: While sitting in a long sitting position with their knees straight and
their bodies upright, the participants were asked to touch the soles of their bare feet to
the assessment table. In this position, they were told to reach as far as they could reach on
the coffee table with their elbows straight and palms facing the floor. By measuring the
distance between the fingertip and the coffee table, those who could reach the table received
"0" values, those who could reach beyond the table (+) cm and those who could not reach (-)
cm. The best value after two measurements was recorded.
Static stretching procedure: For the static stretching exercise, the participant was asked to
lie down in the supine position. The investigator had the dominant side passively flexed the
hip to 90 degree, extending the knee to the end that could be tolerated. At the last point,
it was waited for 30 seconds and then the hamstring muscle was relaxed and rested for 30
seconds. A total of 5 minutes of application was completed by doing 5 repetitions with 30
seconds of static stretching and 30 seconds of rest in each period.
percussion massage procedure: Hypervolt (Hyperice, California, US) device was applied to the
dominant hamstring muscle for 5 minutes at 53 Hz frequency with the "hard ball" head.
Semitendinosus and semimembranosus muscles were focused in the first 2.5 minutes of the
massage treatment, and the biceps femoris muscle in the second 2.5 minutes. By paying
attention to the equal amount of pressure applied throughout the massage, the massage was
started from the medial side of the muscle in the first part of the application and the
massage was completed by moving the device from distal to proximal and from proximal to
distal in a straight line within 20 seconds. While passing to the last 2.5 minutes, the
massage device was shifted laterally at the distal end of the muscle, and the application was
made from distal to proximal and then distally. Thus, the massage for each muscle was started
from the medial and ended laterally.
