N/A Osteoarthritis of the knee joint. Intervention 1: The standard treatment that applied to the each of two groups was 1-A 1 MHz continous mode Ultrasound with applicator cross section of 0/8 cm2 in medial and lateral aspect of joint line, duration of 5 min and intensity of 1 w/cm2 .2- TENS current with frequency of 100 Hz and pulse duration of 0/05 ms and the time of treatment of 15 min.3-Infra Red radiation with power of 250 watt and 45 cm distance from the knee4- SLR in supine position, 30 fold. In the control group A Gal-Al-As diode laser device with a power output of 30 mW and a wavelength of 830 nm was used. Probe of laser applied in pattern of cycloid grid in 5 points in antero-medial side and 5 points in the antero-lateral side of knee joint line. In Each session 3 j/per point and a total dosage of 30j/cm2 were applied. In the placebo group, the same points and the similar duration was applied while turned off the laser device. Intervention 2: The standard treatment that applied for the control group was 1-A 1 MHz continous mode Ultrasound with applicator cross section of 0/8 cm2 in medial and lateral aspect of joint line, duration of 5 min and intensity of 1 w/cm2 .2- TENS current with frequency of 100 Hz and pulse duration of 0/05 ms and the time of treatment of 15 min.3-Infra Red radiation with power of 250 watt and 45 cm distance from the knee 4- Straight Leg Raising in supine position, 30 fold. The same Gal-Al-As diode laser device was applied on the same points as the Active laser group while turned off the laser device. Probe of laser was applied in pattern of cycloid grid in 5 points in antero-medial side and 5 points in the antero-lateral side of knee joint line. The duration of treatment on each point was 30 second.
