Adjunctive Effects of Heat vs Contrast Therapy With Otago Exercises on Patellofemoral Pain Syndrome

The goal of this clinical trial is to determine the adjunctive effects of heat therapy and contrast therapy when combined with the Otago exercise program in individuals with patellofemoral pain syndrome aged 18 to 40 years. The study aims to assess whether these interventions can help reduce pain and swelling, improve knee range of motion, and decrease functional limitations associated with patellofemoral pain syndrome. Researchers will compare two groups one receiving heat therapy with the Otago exercise program and the other receiving contrast therapy with the Otago exercise program to see which approach provides greater improvement in outcomes. Participants will undergo regular supervised sessions that include the assigned thermal therapy and a structured set of Otago exercises targeting lower limb strength, balance, and mobility.
