Limited ankle flexibility (\"dorsiflexion\" - how far participants can lift their toes toward the shin) may worsen PFP by altering leg movements. This study investigates whether adding ankle flexibility exercises to standard knee-strengthening programs improves outcomes for young adults with PFP. Active adults aged 18-30 with PFP and limited ankle flexibility (measured with a simple tool) are eligible, excluding those with prior knee\u002Fankle surgeries, fractures, or conditions like arthritis. Sixty-four participants will be randomly assigned to either an Exercise + Ankle Training group (standard knee exercises plus targeted ankle training) or an Exercise-Only group for 8 weeks under physiotherapist guidance. Outcomes include improvements in knee pain scores (Kujala Scale), ankle flexibility changes, and muscle coordination measured with non-invasive sensors. If effective, ankle flexibility training could provide a low-cost addition to current treatments, helping patients resume activities with less pain. The study follows international ethical guidelines and has received preliminary ethics approval (No. TJUS-2025-054).",[27],"Patellofemoral Pain, PFP","NOT_YET_RECRUITING","2025-04-25",{"date":31,"type":32},"2025-05-06","ACTUAL",{"date":31,"type":21},{"date":35,"type":21},"2025-09-10",{"name":37,"class":38},"Tianjin University of Sport","OTHER",""]
