Correlation Between Gluteus Squeeze Strength and Gluteus Maximus Strength Using a Tensiometer and Hand-held Dynamometer

Background: Gluteus maximus major plays a primary role in extending the hip joint and plays an important role in performing various functions such as gait control and increase in stability of the sacroiliac joint. Although gluteus squeeze exercises show high electromyographic activity of the gluteus maximus and are convenient exercises that can be useful in daily life, research on gluteus squeeze is insufficient compared to other traditional gluteus maximus exercises. Objectives: The purpose of this study was to investigate the correlation between gluteus squeeze strength and gluteus maximus strength using a tensiometer and hand-held dynamometer. Methods: Twenty-two healthy adults (males 13, females 9) were enrolled in this study. The subject was trained to explain and familiarize with the measurement process in advance for 10 minutes before all measurements were made. First, the gluteus squeeze strength was measured through a tensiometer connected to the belt, and after the muscle strength of the gluteus maximus was measured in the manual muscle test posture using a hand-held dynamometer. Results: We found that the positive correlation between the gluteus squeeze strength and the gluteus maximus strength (right, r = 0.826, p < 0.001) (left, r = 0.830, p < 0.001). Conclusions: This study suggested that gluteus squeeze exercise is effective to strengthen the gluteus maximus and the strength of gluteus maximus can be easily checked using a tensiometer in clinics.
