Patellofemoral Cartilage and Peripheral Knee Muscle Injury
Conditions
Interventions
90°-IWS:Stand tall, leaning against the wall, with your head level and looking straight ahead. You can simply place your hands lightly on your legs, hang them by your sides, or hold them out in front
60°-IWS:Based on the distance measured in the 90° IWS, utilize two-thirds of this measurement to determine the distance between the heel and the wall for this action(60°-IWS). The criteria for all sub
45°-IWS:Based on the distance measured in the 90° IWS, utilize half of this measurement to determine the distance between the heel and the wall for this action. The criteria for all subsequent actions
