The purpose of the present study was to analyze the neuromuscular responses during the performance of a sit to stand [STS] task in water and on dry land.
10 healthy subjects, five males and five females were recruited for study. Surface electromyography sEMG was used for lower limb and trunk muscles maximal voluntarty contraction [MVC] and during the STS task.
Muscle activity was significantly higher on dry land than in water normalized signals by MVC from the quadriceps-vastus medialis [17.3%], the quadriceps - rectus femoris [5.3%], the long head of the biceps femoris [5.5%], the tibialis anterior [13.9%], the gastrocnemius medialis [3.4%], the soleus [6.2%]. However, the muscle activity was higher in water for the rectus abdominis [-26.6%] and the erector spinae [-22.6%].
This study for the first time describes the neuromuscular responses in healthy subjects during the performance of the STS task in water. The differences in lower limb and trunk muscle activity should be considered when using the STS movement in aquatic rehabilitation.
本研究旨在分析在水中和陆地上进行坐站[STS]任务时的神经肌肉反应。
招募了 10 名健康受试者，其中男性 5 名，女性 5 名。表面肌电图 sEMG 用于测量下肢和躯干肌肉在最大自主收缩[MVC]和 STS 任务期间的最大活动。
与干地相比，在水中，股四头肌-股直肌[17.3%]、股四头肌-股外侧肌[5.3%]、股二头肌长头[5.5%]、胫骨前肌[13.9%]、腓肠肌内侧[3.4%]和比目鱼肌[6.2%]的肌肉活动明显更高。然而，腹直肌[-26.6%]和竖脊肌[-22.6%]的肌肉活动在水中更高。
本研究首次描述了健康受试者在水中进行 STS 任务时的神经肌肉反应。在水中康复治疗中使用 STS 运动时，应考虑下肢和躯干肌肉活动的差异。
