Intervention 1: LASER Group: A low-level Ga-As LASER was applied with 5 KHz frequency, a 100 mW point probe (average power), wavelength 905 nm, pulse duration 200 ns, 9 J/cm2 dosages per minute, for 6 minutes per session. In addition, this group received hot pack and exercises including strengthening of quadriceps, adductors of the hip, and stretching of iliotibial band, buttock, calf and hamstring muscles. A 16 session's treatment program which lasted 4 weeks and 4 sessions per week was performed. Intervention 2: Action Potential Simulation Group: We applied Action Potential Simulation with intensity of 1mA, 150 Hz frequency, for 16 minutes per session. This group received hot pack and exercises including strengthening of quadriceps, adductors of the hip, and stretching of iliotibial band, buttock, calf and hamstring muscles. A 16 session's treatment program which lasted 4 weeks and 4 sessions per week was performed.
