Objective: To compare the effects of Mulligan traction leg raise vs. slump stretching on pain and passive leg raise in lumbar radiculopathy. Study design: Quasi experimental study. Place and Duration: Family Clinic. (September 2020 to February 2021). Methodology: Consecutive sampling technique was used to select a sample of 40 patients from physiotherapy department of family clinic, Lahore. Study was completed in 6 months. Patients randomly allocated into 2 groups. Group A performed Mulligan traction leg raise with lumbar stabilization exercises and Group B performed slump stretching with lumbar stabilization exercises. Patient evaluated for improvement in symptoms through numeric pain rating scale and goniometry. Each group received treatment session 3 times per week for 4 weeks. Data was analyzed by using SPSS version 21. Results: The result cleared that Group A Mulligan traction leg raise showed significant results in pain and passive SLR ROM with p value less than 0.05. Group A showed decreased in pain with mean value of 1.60 plus or minus 1.536 as compared to Group B where pain is 4.00 plus or minus 1.947. Where Group A showed improvement in passive SLR with mean value of 86.15 plus or minus 7.206 as compared to Group B where passive SLR ROM with mean values is 59.35 plus or minus 12.683. Group B showed improvement but not showed significant results in comparison of group A. Conclusion: It is concluded that Group A Mulligan traction leg raise with lumbar stabilization exercises is much better technique to improve pain and passive SLR ROM in lumbar radiculopathy patients. Group B slump stretching with lumbar stabilization exercises is also very effective but results showed significant effects of Mulligan traction leg raise.
