Effects of Mulligan Mobilization With and Without Dry Needling in Runner's Knee

Effects of Mulligan Mobilization With and Without Dry Needling in Runner's Knee

The aim of this study is to determine the effects of Mulligan mobilization with and without dry needling on pain, range of motion, flexibility, functional disability and muscle strength in patients with Runner's Knee.

Runner's knee or patellofemoral pain syndrome (PFPS) is a common cause of anterior knee pain in young active individuals. Patellofemoral pain (PFP), or anterior knee pain (AKP), is a common musculoskeletal disorder. It involves dysfunction in mechanical forces between the patella and the femur. The worldwide PFP prevalence has been reported as 15-45% of population. Females are at two times higher risk of PFP than males, especially young active females. The aim of this study is to determine the effects of Mulligan mobilization with and without dry needling in Runner's Knee in a randomized clinical trial.

The study will be randomized clinical trial. The study will be conducted at Johar Pain Relief Center, Lahore. The study will be completed within eight months after synopsis approval from ethical committee of Riphah College of Rehabilitation and Allied Health sciences. Sample size will be 40 (20 in each group). Non-probability convenience sampling technique will be used to recruit the Runner's Knee patients in the study and then they will be divided into two groups by simple randomization through sealed opaque envelope. Mulligan mobilization with dry needling will be given to group A. Mulligan mobilization without dry needling will be given to group B. Outcome measures will be pain, knee range of motion, flexibility, functional disability and muscle strength measured through Numeric pain rating scale (NPRS), goniometer, Kujala Patellofemoral Scale and Modified Sphygmomanometer Test (MST) respectively. Data will be analyzed by SPSS version 25.

• Pain scoring rate on numeric pain rating scale (NPRS) ≥ 3 during at least two activities.
• Duration lasting longer than two months.

Exclusion Criteria:

• Patients with a history of meniscus tears, bursitis, patellar tendon injury, ligamentous injury, joint degeneration, patellofemoral dislocation and / or recurrent subluxation.
