Abstract
Twenty-two healthy college students aged between 19 and 25 participated in this study. The participants had no history of any significant lower leg injuries. Participants’ bi-lateral hip flexion ROM was evaluated by a Certified Athletic Trainer prior to treatment through goniometric measurement techniques. Then, the participants received diathermy @ 48 W continuous for 15 minutes on one hamstring group and thermal ultrasound @ 3.3 Mhz 1.5 W/cm2 for 7 minutes to the other hamstring group. Following the treatments, hip flexion ROM was re-assessed at the following intervals: immediately following treatment, 2 minutes, 5 minutes and 10 minutes post treatment.
