    The Graston Technique® Increases Hamstring Flexibility
    (North Dakota State University, 2014) Nejo, Yusuke
    Soft tissue mobilization techniques have been reported to increase hamstring flexibility. However, no one has reported the effects of the Graston Technique® on increasing hamstring flexibility. The purpose of this study was to determine the changes in range of motion after applying the Graston Technique® to tight hamstring muscles. Forty five college-aged students participated; 3 well-trained athletes, 35 physically trained students, and 7 untrained students (total 30 men and 15 women). Pre- and post-treatment measurements on hamstring flexibility were taken at the 90/90° position using a goniometer. There was a statistically significant difference between the sham treatment group and the treatment groups (an only Graston Technique® group and a whole Graston Technique® treatment group). However, there was no significant difference between the only Graston Technique® group and the whole Graston Technique® treatment group. Also, range of motion increase was affected by the adipose tissue thickness.
