Background and purpose: Osteoporosis is a silent bone disorder that commonly affects old age women with a high impact on the body functions and working capacity with high incidence of falling and exposure to fracture even with minor trauma. The purpose of this study was to find out the effect of low level laser therapy(LLLT) on bone mineral density (BMD) in osteoporotic elderly women by using dual energy X-ray absorpitomeitry (DEXA). Methods and results: The study was conducted on thirty women selected from orthopedic out-patient clinic from zagazig general hospital (Egypt) as osteoporotic women. They were assigned randomly into two groups equal in number their age ranged from 50-65 years old. Each women of the two groups was evaluated by (DEXA), their T-Score ranged from (-4.5: -2.5g/cm²) the evaluation done at the beginning of study and at end of it. The study group (A) received (LLLT) for 3 months as 3 sessions /week each session last for 20 minutes plus their traditional medical treatment. and control group (B) only received their traditional medication Results: There was significant improvement in the values of bone mineral density (BMD) by 36.3% in group (A) compared to group (B).Conclusion: The study concludes that application of low level laser can help to increase bone mineral density in osteoporotic women
