Running Retraining

Running retraining for patellofemoral pain is presented as a way to reduce knee pain in runners by changing how they run through targeted feedback. The lecture first explains that although recreational running benefits cardiovascular, metabolic, and mental health, musculoskeletal injuries are common, and patellofemoral pain is one of the most frequent problems. Key ideas include the definition of gait retraining, the use of a faded feedback approach, and the goal of changing specific biomechanical variables such as hip adduction. Evidence is reviewed showing that runners with patellofemoral pain often demonstrate greater hip adduction, hip internal rotation, pelvic drop, and reduced hip flexion. The lecture also contrasts running retraining with strengthening exercise: exercise can improve pain and function, but it does not appear to change running mechanics. Several studies are compared to show that running retraining can improve symptoms, function, and biomechanics, especially when feedback is reduced gradually over time. Practical options such as increasing step rate, altering foot strike, and minimalist footwear are discussed, along with limitations, mixed real-world results, and the risk of shifting load to the calf, Achilles tendon, or ankle.
