摘要： 目的 比较健康成人陆地步行及水中平板步行时步态参数及表面肌电图特征。方法 2015年1月至9月,分别在陆地及水中平板步行训练过程中,采用三维步态分析系统及表面肌电图系统同步采集10名健康成人步行时空参数及表面肌电信号。结果 与陆地步行相比,自感舒适速度下水中平板步行步态周期显著增加(t=-11.411, P<0.001),步长无显著性差异(Z=-0.357, P>0.05),步行速度明显降低(Z=-2.803, P<0.01),步频显著降低(t=7.421, P<0.001),摆动相百分比增加(t=-5.252, P<0.05);水中平板步行过程中,股二头肌、腓肠肌、胫前肌的平均肌电积分明显低于陆地步行时(t>3.984, P<0.01),但股直肌无显著性差异(t=0.054, P>0.05)。结论 水中平板步行时,步态及肌肉收缩强度与陆地步行均有所差异,其运动生理及神经控制机制需要进一步研究。

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, P<0.001) and percentage of the swing phase (t=-5.252, P<0.05), significant reduction in walking speed (Z=-2.803, P<0.01) and step frequency (t=7.421, P<0.001). There was no significant difference in step strength (Z=-0.357, P>0.05). The integral electromyography of biceps femoris, gastrocnemius, tibialis anterior muscle were significant less than iEMG on land (t>3.984, P<0.01), but no significant difference of rectus femoris (t=0.054, P>0.05). Conclusion There are significant differences in gait and muscle contraction intensity between land walking and UWTT. The dynamic physiology and neural control of UWTT need further study.
