Active clinical trials for "Chondromalacia Patellae"

Objective: to investigate whether females with PF OA descend stairs with different muscular recruitment strategies contrasted with similar aged healthy females. Methods: An observational comparative study will be conducted with thirty females with PF OA and 10 healthy ones. The onset times and electromyography (EMG) duration of multifidus, transversus abdominus (TrA), gluteus medius (GM), and vasti muscles will be measured by quantitative EMG during stair descent task. hypothesis: Investigators hypothesize that there won't be a significant difference between females with PF OA and their matched healthy group regarding the onset times and duration of vastus medialis obliqus (VMO), vastus lateralis (VL), gluteus medius (GM), multifidus, and transversus abdominus (TrA), during stair descent task.
