Effectiveness of High Power Laser Therapy on Pain and Isokinetic Power in Athletes With Proximal Hamstring Tendinopathy: a Randomized Controlled Trial

Proximal hamstring tendinopathy (PHT) is tendinopathy of the semimembranosus and/or biceps femoris/semitendinosus complex. Previous studies have shown the efficacy of laser therapy in the treatment of tendinopathy. To the best of the investigator's knowledge, no study has compared the effects of high-power LASER therapy with conventional physiotherapy programs in proximal hamstring tendinopathy patients. Therefore, this study aimed to assess the effects of high-power laser therapy on pain and muscle power in proximal hamstring tendinopathy patients.

Detailed Description

2 arms comparative pretest-posttest experimental research design with random allocation of subjects into groups (experimental and control group) using the lottery method. A total of thirty-six participants aged between 18-35 (mean age) years, were recruited in the present study. The selected participants were randomly allocated into experimental and control groups using the lottery method and website randomization.com with eighteen participants in each group. The participants and outcome assessor were kept blinded to the allocation. In the experimental group, the high-power laser was given whereas in the control group conventional physiotherapy treatment was given for 4 weeks. Conventional physiotherapy treatment included the US, moist heat pack, and home exercises. Home exercises include nordic hamstring exercises - 2 sets of 5 repetitions, 3 days/week for 3 weeks.
