In physiotherapeutic practice, special attention is being given to the reciprocal anatomical, physiological, and biomechanical relationship of the pelvis and the structures connected to it. However, the scientific literature shows mainly the theoretical information about their mutual connections. The lack of information about these relations from a practical aspect coupled with the paucity of scientific papers on the impact of posture changes on the pelvic floor led the authors to conduct this study. The primary aim of this study was to compare the resting and functional bioelectrical activities of pelvic floor muscles (PFMs) depending on three different positions of the lower limbs (positions A, B, and C) in the supine position.
This was a prospective observational study evaluating resting and functional activities of the PFM depending on the position of the lower limbs. The study was carried out at the Department and Clinic of Urology, University Hospital in Wroclaw, Poland and the target group were women in the menopausal period. Bioelectrical activity of PFM was recorded using a surface electromyographic instrument in the supine position. Results of the values obtained in A, B, and C positions were compared using a one-way analysis of variance.
In position A, the average resting surface electromyography (sEMG) activity of PFM was 6.9±2.6 µV; in position B, the result was 6.9±2.5 µV and in position C, the resting sEMG activity was 5.7±1.8 µV (=0.0102). The results of the functional bioelectrical activity of PFM were as follows: position A - 20.3±11.8 µV, position B - 19.9±10.6 µV, and position C - 25.3±10.9 µV (=0.0104).
The results showed that in the supine position, the PFM achieved the lowest resting activity and the highest functional activity. Therefore, the supine position can be recommended for the diagnosis and therapy of weakened PFM.
在物理治疗实践中，骨盆及其相连结构之间的相互解剖学、生理学和生物力学关系受到特别关注。然而，科学文献主要展示了关于它们相互联系的理论信息。从实践角度来看，缺乏关于这些关系的信息，再加上关于姿势变化对盆底影响的科学论文数量稀少，促使作者开展本研究。本研究的主要目的是比较仰卧位时下肢处于三种不同位置（位置A、B和C）时盆底肌肉（PFMs）的静息和功能性生物电活动。
这是一项前瞻性观察性研究，评估PFMs的静息和功能性活动与下肢位置的关系。该研究在波兰弗罗茨瓦夫大学医院泌尿外科进行，目标人群为处于围绝经期的女性。使用表面肌电图仪在仰卧位记录PFMs的生物电活动。对在A、B和C位置获得的值进行单因素方差分析比较。
在位置A，PFMs的平均静息表面肌电图（sEMG）活动为6.9±2.6微伏；在位置B，结果为6.9±2.5微伏，在位置C，静息sEMG活动为5.7±1.8微伏（P = 0.0102）。PFMs功能性生物电活动的结果如下：位置A - 20.3±11.8微伏，位置B - 19.9±10.6微伏，位置C - 25.3±10.9微伏（P = 0.0104）。
结果表明，在仰卧位时，PFMs的静息活动最低，功能性活动最高。因此，仰卧位可推荐用于诊断和治疗盆底肌肉功能减弱。
