The aim of this study was to use sEMG to measure the neuromuscular activity during the TUG task in water, and compare this with the responses for the same task on land. Ten healthy subjects [5 males and 5 females [mean ± SD]: age, 22.0 ± 3.1 yr; body mass, 63.9 ± 17.2 kg. A telemetry EMG system was used on the following muscles on the right side of the body: the quadriceps - rectus femoris [RF], long head of the biceps femoris [BF], tibialis anterior [TA], gastrocnemius medialis [GM], soleus [SOL], rectus abdominis [RA] and erector spinae [ES]. Each subject performed the TUG test three times with five minutes recover between trials in water and on dry land. The % MVC was significantly different (p < 0.05) for majority of the muscles tested during the TUG water compared to dry land. % MVC of RF [p = 0.003, t = 4.07]; BF [p = 0.000, t = 6.8]; TA [p = 0.005, t = 5.9]; and SOL [p = 0.048, t = 1.98]; RA [p = 0.007, t = 3.45]; and ES [p = 0.004, t = 3.78]. The muscle activation of the trunk and the lower limb [VM RF, BF, TA, GM and SOL] were lower in water compared to dry land, when performing a TUG test.
本研究的目的是使用表面肌电图（sEMG）测量水中定时起立行走（TUG）任务期间的神经肌肉活动，并将其与在陆地上完成相同任务的反应进行比较。十名健康受试者[5名男性和5名女性，平均±标准差：年龄，22.0±3.1岁；体重，63.9±17.2千克]。在身体右侧的以下肌肉上使用遥测肌电图系统：股四头肌-股直肌（RF）、股二头肌长头（BF）、胫骨前肌（TA）、腓肠肌内侧头（GM）、比目鱼肌（SOL）、腹直肌（RA）和竖脊肌（ES）。每位受试者在水中和陆地上各进行三次TUG测试，每次测试之间休息五分钟。与陆地相比，在水中进行TUG测试时，大多数测试肌肉的最大自主收缩百分比（%MVC）有显著差异（p<0.05）。RF的%MVC[p = 0.003，t = 4.07]；BF[p = 0.000，t = 6.8]；TA[p = 0.005，t = 5.9]；SOL[p = 0.048，t = 1.98]；RA[p = 0.007，t = 3.45]；ES[p = 0.004，t = 3.78]。在进行TUG测试时，与陆地相比，水中躯干和下肢（VM RF、BF、TA、GM和SOL）的肌肉激活程度较低。
