Back ground: Low back dysfunction LBD is a major health problem and a major cause of medical expenses and disablement .Laser puncture therapy can be used to treatment musculoskeletal disorder such as back pain. Purpose :To investigate the effect of the laser puncture on pain ,ROM, and function in activities of daily living in cases with low back dysfunction.Method :Subjects: Thirty patients 17female and 13 male with LBD, aged from 40 to 60 years, were randomly assigned into two treatment groups . Subjects in the control group (A) (n=15) with a mean age (45.7±6.6) years, mean weight (77.4±10.4) Kg , mean height (169.3±21.7) cm . Where subject in experimental group (B) (n = 15) with a mean age (46.4±6.7) years, mean weight (79.1±12.8) Kg, mean height (170.7±10.1) cm participated in this study. Control group (A)(n=15)received traditional physical therapy treatment (infrared radiation , ultrasonic and therapeutic exercise ). And experimental group (B) (n = 15) were treated with infrared radiation, ultrasonic , therapeutic exercise as well as laser therapy in three days / week for four weeks. Measurement of pain level was assessed by VAS, patients functional disability was assessed by Oswestry disability index and back ROM by BROM device. Wereassessed before and after treatment in both groups.Result: Showed that a significant effect of laser puncture on pain level , Pain Intensity as the mean value of pre-treatment was in(A) (4.9 ±1.3 )and(B) (6.9±1.1) for post treatment was in (A) (3.2 ± 1.5)and(B) (3.5±1.2), functional disability pretreatment was in(A)(50.9± 15.3) and (B) (51.9±13.4) for post treatment was in(A) (41.7 ± 15)and (B)(28.7±12.6) ,back ROM in patients pre-treatment was in(A)(122.9 ± 12.8) and ( B)(131.6±10.9)for post treatment was in (A) (127.7± 11.1)and(B)(135.2±9.8) with mechanical low back dysfunction. Conclusion : It was concluded that treatment with laser puncture were effective in reducing pain level ,functional disability and improving back Rang of motion
