PFPS, also known as patellofemoral pain syndrome, is a prevalent musculoskeletal condition that primarily affects adolescents and young adults. When engaging in various activities, such as stair climbing, running, jumping, kneeling, or prolonged sitting, it is characterized by aching pain in the peripatellar region. Any disruption of these would result in abnormal PFJ overloading. Normal patellar tracking on the trochlea groove relies on the coordination and balance of many structures, including soft tissues, muscles, tendons, ligaments, and the shape of articular surfaces around the knee joint. Research in a variety of fields has received support the therapeutic exercise known as "clamshells" for stabilizing the pelvis by strengthening the hip abductors and external rotators.VMO strengthening exercises are also essential in keeping the patella in the trochlear groove and lowering the lateral vector force on the patellofemoral joint. This research aims to evaluate the effects of clamshells exercise and Vastrus medialis oblique strengthening exercise in patients with Patellofemoral pain syndrome.
The study would be randomized clinical trial. Total fourty two subjects will be assigned randomly by using lottery method into two groups. Group A will be given clamshell exercise with baseline treatment while Group B will receive targeted vastrus medialis oblique strengthening exercise with baseline treatment. After confirmation of diagnosis with physical examination as well as zohlar's test /20 cm step down test are recommended. Numeric pain rating scale (NPRS) and Lower extremity functional scale (LEFS) would be used as an outcome measure tools for pain and functional limitation respectively. Measurements will be taken at (Baseline and at the end of treatment session). The collected data will be analyzed in Statistical Package for the Social Sciences (SPSS) 25.0. Parametric/non-parametric tests will be applied after testing normality of data.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Standard clamshells method | Experimental | The patient is asked to lie in a side-lying position with the weak limb up, both hips flexed at 45°, the knees flexed at 90°, and neither the feet nor back not in contact with the wall. Keeping both their heels and the first metatarsal head together, the patient separated their knees and rotated the weak limb upward. The patients is instructed not to tip it backward and to hold the pelvis in a neutral position.Common treatment will be given to each patient includes hot pack for 10 minutes and knee isometric contraction exercises and SLR( 3-5 sets of 10 repetitions) |
|
| Targeted VMO strengthening | Experimental | The patient is asked to lie in a supine lying position with arm next to the body. After that asked the patient to perform SLR exercise in an external hip rotation with the simultaneous contraction of the ankle dorsiflexors. Common treatment will be given to each patient includes hot pack for 10 minutes and knee isometric contraction exercises and SLR( 3-5 sets of 10 repetitions |

| Measure | Description | Time Frame |
|---|---|---|
| Pain intensity | numeric pain rating scale(NPRS) is used to measure intensity of pain.Score ranges from 0-10.Higher values mean greater level o pain. | Baseline to 6th week |
| Functional disability | The lower Extremity Functional Scale (LEFS) is used to measure the functional status of the lower extremity. score ranges from 0-80. lower values mean greater functional limitation. | Baseline to 6th week |
| Muscle strength | Sphygmomanometer is used to measure muscle strength. higher readings on sphygmomanometer represents better muscle strength. | Baseline to 6th week |
