Temporal Activation of Core Muscles and Vasti in Isolated Patellofemoral Osteoarthritis

Egypt42 participantsStarted 2019-03-01

Plain-language summary

Objective: To compare the temporal muscle activation between females with PF OA and normal controls during stair ascent. Methods: An observational comparative study was conducted with thirty-one females with PF OA and 11 healthy ones. The onset times of multifidus, transversus abdominus (TrA), gluteus medius (GM), and vasti muscles were measured by quantitative Electromyography during stair ascent task. hypothesis: Investigators hypothesized that there won't be a significant difference between females with PF OA and their matched healthy group regarding the onset times of vastus medialis obliqus (VMO), vastus lateralis (VL), gluteus medius (GM), multifidus, and transversus abdominus (TrA), during stair ascent task.
