: The aim of this study was to assess the effect of a single session of EMG biofeedback in a group of postmenopausal women on improving technique in pelvic floor muscle (PFM) contractions (exercises). : Sixty-two women aged 60 to 85 years (69 ± 4; mean ± SD) participated in the study. We assessed the technique of PFM exercises via surface electromyography (EMG) using a vaginal probe. A single assessment sequence consisted of 11 exercises involving the conscious contraction of the PFM, during which the order of activation for selected muscles was determined. We then awarded scores for exercise technique on a scale from 0 to 4, where 4 represented the best technique and 0 represented no activation of PFMs. In the second assessment, we used a biofeedback method to teach PFM exercise technique. : In total, 32% (n = 20) of the participants were unable to correctly perform the first PFM contraction, scoring 0.9 ± 0.79. After a single EMG biofeedback session, these women received 1.7 ± 1.08 scores ( = 0.003). In the tenth exercise, there was also a statistically significant improvement between the first (baseline) and second assessment (1.7 ± 1.34 and 2.15 ± 1.09, respectively; = 0.037). For the remaining exercises, the results were not statistically significant, but we observed a positive trend of change. : The use of a single EMG biofeedback session is an effective method of improving technique in PFM exercises in a group of women who initially performed them incorrectly.
本研究的目的是评估单次肌电图生物反馈对一组绝经后女性盆底肌肉(PFM)收缩(锻炼)技巧改善的影响。62名年龄在60至85岁(69±4;均值±标准差)的女性参与了该研究。我们使用阴道探头通过表面肌电图(EMG)评估PFM锻炼技巧。单次评估序列包括11项涉及PFM自主收缩的锻炼,在此期间确定所选肌肉的激活顺序。然后我们根据0至4的评分标准对锻炼技巧进行评分,其中4代表最佳技巧,0代表PFM未激活。在第二次评估中,我们使用生物反馈方法教授PFM锻炼技巧。共有32%(n = 20)的参与者无法正确进行首次PFM收缩,得分为0.9±0.79。经过单次肌电图生物反馈训练后,这些女性的得分为1.7±1.08(P = 0.003)。在第十项锻炼中,第一次(基线)和第二次评估之间也有统计学上的显著改善(分别为1.7±1.34和2.15±1.09;P = 0.037)。对于其余锻炼,结果无统计学意义,但我们观察到了积极的变化趋势。使用单次肌电图生物反馈训练是改善一组最初PFM锻炼技巧不正确的女性锻炼技巧的有效方法。
