Abstract Background: Majority of muscle injuries are results of excessive strain on muscle, which occurs during sprinting or jumping. This injury often affects the myotendinous junction of superficial muscles spanning across two joints, such as the rectus femoris, semitendinosus, and gastrocnemius muscles. The muscle injury recovery process is slow and often changes the original mechanical properties of the damaged muscle. The goal of rehabilitation is to recover the muscle as fast as possible offering the lowest risk of injury recurrence. Hamstrings muscle strains are among the most common injuries in sport. Purpose: the purpose of this study was to compare between the effect of low level laser therapy and plasma rich platelets on recovery of hamstrings strain. Subjects: Thirty male athletes diagnosed as grade I and II hamstrings strain with age between 20-35 years. Methods: Patients were distributed randomly into three groups. The first group (A) consisted of 10 patients with mean age (27.20±3.71) who received plasma rich platelets (PRP). The second group (B) consisted of 10 patients with mean age (27.10±3.70) who received laser treatment was applied. 3times/week starting from second day for 2 weeks with irradiation beam with 60 sec/point with dose 1 J/cm². The third group (C) consisted of 10 patients with mean age (26.60±4.25) who received both treatments at the same time |
