Abstract: "Purpose/Hypothesis : The purpose of this study was to compare the effects of common physical therapy techniques on acute hamstring muscle passive stiffness. The hypothesis is that dry needling , stretching , and foam rolling will improve hamstring passive stiffness , and that eccentric exercise may have the reverse effect of increasing passive muscle stiffness.Number of Subjects : 100 subjects.Materials/Methods : Subjects who met inclusion criteria had their initial passive hamstring length of the right leg measured using the ""90-90 test€ and a bubble inclinometer by a researcher blinded to the treatment. The measurement was taken when the subject perceived a ""strong but tolerable stretch€. They were randomized to one of 5 groups , dry needling (DN) , foam rolling , stretching , eccentric exercise , or control. The DN group received pistoning technique to 3 to 5 trigger points. The foam roller group performed self-guided myofascial release using a 6 inch diameter foam roller in a long sitting position with knees extended and feet relaxed. . Subjects rolled for 30 seconds with 30 seconds rest for 3 sets. The stretching group preformed an active self-stretch in supine held for 30 seconds with 30 seconds rest for 3 sets. The exercise group performed an eccentric hamstring exercise commonly known as the Nordic exercise for 10 repetitions with 30 seconds rest for 3 sets. At completion of treatment the subject had their hamstring range"
