About this study

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.

Primary outcomes

  1. Pain: Numeric Pain Rating Scale (NPRS)

    Time frame: 6th Week

    Patients' overall assessment of pain will be provided using the numeric pain rating scale (NPRS). The NPRS is known to be a sensitive and reliable scale for clinical and experimental evaluation of pain intensity. The score ranges from 0, indicating no pain, to 10, expressing worst imaginable pain. The reliability of numeric pain rating scale (NPRS) is 0.92 (0.87, 0.95).

  2. Functional Disability: Kujala Patellofemoral Scale (KPS)

    Time frame: 6th Week

    The Kujala score will be used to evaluate functional disability in patients with patellofemoral disorder. Kujala Patellofemoral Scale (KPS) is a 13-item, self completed instrument with different categories consisted of limping, weight bearing, walking, stairs, squatting, running, jumping, prolonged sitting, pain, swelling, painful patellar movements, muscle atrophy and flexion deficiency. The total score ranges from 0 to 100, with higher scores indicating lower levels of pain/ disability. It has been claimed that this tool is user-friendly and the test-retest reliability is highly acceptable. This tool is valid and sensitive for research purposes. The test-retest reliability is excellent with an intra-class correlation coefficient of 0.908 (p < 0.001; 95% CI [0.842-0.947]). The internal consistency is strong with Cronbach's alpha of 0.952 (p < 0.001).

  3. Knee Range of Motion (ROM) (Flexion) : Goniometer

    Time frame: 6th Week

    Universal Goniometer is the most commonly utilised clinical tool for measuring joint range of motion due to its ease of use, low cost, and demonstrated reasonable levels of reliability and validity in numerous studies. Validity and intertester reliability (r =.97-.98; ICC =.98-.99) are both high.

  4. Knee Range of Motion (ROM) (Extension) : Goniometer

    Time frame: 6th Week

    Universal Goniometer is the most commonly utilised clinical tool for measuring joint range of motion due to its ease of use, low cost, and demonstrated reasonable levels of reliability and validity in numerous studies. Validity and intertester reliability (r =.97-.98; ICC =.98-.99) are both high.

  5. Flexibility: Goniometer

    Time frame: 6th Week

    Universal goniometer or inclinometer will be used for evaluating the knee joint range of motion and hamstring flexibility.

  6. Muscle strength: Modified Sphygmomanometer Test (MST)

    Time frame: 6th Week

    A sphygmomanometer will be used for the evaluation of all muscular groups. A statistically significant correlation of moderate to high magnitude (0.58 ≤ r ≤ 0.81) is observed for concurrent validity of the MST with fixed stabilization for all muscle groups. Regarding inter-rater reliability, it is observed statistically significant ICC considered excellent to good (0.72 ≤ r ≤ 0.94) for all muscle groups. Regarding test-retest reliability, is good to excellent ICC (0.64 ≤ r ≤ 0.94) for all muscle groups. The MST with fixed stabilization is valid and reliable for clinical measurement of muscle strength.
