Gait and Surface Electromyogram Characteristics in Underwater Treadmill Training / 中国康复理论与实践

ABSTRACT

Objective To explore the characteristics of gait and surface electromyography (sEMG) of underwater treadmill training (UWTT). Methods From January to September, 2015, gait and sEMG parameters of ten healthy adults were synchronously collected using three-dimensional gait analysis system and sEMG systems on land and UWTT. Results When walking in self comfortable speed, compared with walk on land, there was significant increase in gait cycle (t=-11.411, P0.05). The integral electromyography of biceps femoris, gastrocnemius, tibialis anterior muscle were significant less than iEMG on land (t>3.984, P0.05). Conclusion There are signifi-cant differences in gait and muscle contraction intensity between land walking and UWTT. The dynamic physiology and neural control of UWTT need further study.
