The study is randomized and single-blinded. Ethical approval is taken from ethical committee of Riphah International University, Lahore. Participants who meet the inclusion criteria will be enrolled and allocated in group A & B through sealed envelope method by Non-probability Convenient random sampling technique.

The objective of the study is to determine the effects of mindfulness practice with strength training on pain, kinesiophobia and function among sprinters with patellofemoral syndrome. The study is randomized and single-blinded. Ethical approval is taken from ethical committee of Riphah International University, Lahore. Participants who meet the inclusion criteria will be enrolled and allocated in group A & B through sealed envelope method by Non-probability Convenient random sampling technique. Subjects in Group A will receive the strength training only. Group B will receive the mindfulness-exercise in addition to the strength training protocol. Usual pain, pain during stepping, and pain during running will be assessed using visual analog scales. Functional limitations of the knee will be assessed using the Knee Outcome Survey. Fear of movement, pain catastrophizing, and coping strategies will be measured via the Tampa Scale for Kinesiophobia, the Pain Catastrophizing Scale, and the Coping Strategies Questionnaire, respectively. For strength training we will use Muscle-strengthening Exercise Questionnaire Short Form (MSEQ). These outcomes will be assessed at baseline and after 6 weeks

The data will be analyzed by SPSS, version 25. Statistical significance is P=0.05.

Inclusion Criteria:

• Males and Female between the ages of 18 and 40 years, Report running ≥2 times per week for >45 minutes or a minimum weekly running distance of 10 km, Present a history of insidious onset of signs and symptoms of PFP in 1 or both knees that was unrelated to trauma for at least 3 months before assessment, score <85/100 on the Activities of Daily Living Scale and Sports related of the Knee Outcome Survey (KOS-ADLS)
