文摘

Thigh muscle co-contractions were assessed in 30 healthy adults during gait. Hundreds of consecutive strides were analyzed for each subject. Three different co-contractions among QF and hamstring muscles were identify. Onset-offset instants, excitation intensity and occurrence frequency were provided.
