| 目的 探究不同年龄段盆底功能障碍性疾病患者盆底肌的肌电差异，以期为盆底功能障碍性疾病的临床治疗提供参考。 方法 选取符合入选和排除标准的PFD患者580例，按年龄将其分为A组（≤29岁）163例、B组（30～39岁）161例、C组（40～49岁）114例、D组（50～59岁）128例和E组（≥60岁）14例。对5组患者行盆底肌表面肌电检查，采集和分析指标包括：前、后静息阶段盆底肌肌电波幅的平均值和变异性；快肌阶段盆底肌收缩时的最大肌电波幅值及其上升时间和恢复时间；慢肌阶段收缩时的平均肌电波幅值及变异性。对所采集的指标进行统计学分析，并分析其与年龄的相关性。 结果 前静息阶段，5组患者的盆底肌肌电波幅的平均值和变异性组间比较，差异均有统计学意义（P＜0.05）；快肌阶段，5组患者的盆底肌收缩时肌电波幅的最大值、上升时间和恢复时间组间比较，差异均有统计学意义（P＜0.05）；慢肌阶段，5组患者的盆底肌收缩时肌电波幅的变异性组间比较，差异均有统计学意义（P＜0.05）；后静息阶段，5组患者的盆底肌肌电波幅的平均值组间比较，差异均有统计学意义（P＜0.05）。Spearman相关性分析显示，PFD患者的年龄与前静息阶段的盆底肌肌电波幅的变异性（r=0.20）、快肌阶段盆底肌收缩时达到最大肌电波幅值的上升时间（r=0.18）和恢复时间（r=0.22）、慢肌阶段盆底肌收缩时肌电波幅的变异性（r=0.37）、后静息阶段盆底肌肌电波幅的变异性（r=0.10）均呈正相关，差异均有统计学意义（P＜0.05）；年龄与慢肌阶段盆底肌收缩时肌电波幅的平均值成负相关（r=-0.08），差异有统计学意义（P＜0.05）。 结论 PFD患者随着年龄的增加，其盆底肌的稳定性和协调性逐渐变差，激活速度和恢复速度变慢，募集时间延长、反应变慢、兴奋性变差。 |

| Objective To investigate the pelvic floor muscle functioning of persons with pelvic floor dysfunction (PFD) at different ages in order to provide a reference for clinical treatment. Methods A total of 580 PFD patients were divided into group A (n=163, ≤29 years old), Group B (n=161, 30-39), Group C (n=114, 40-49), Group D (n=128, 50-59) and Group E (n=14, ≥60 years old). All were given a surface electromyography (sEMG) examination of their pelvic floor muscles. Average sEMG amplitude and its variability were recorded in the pre-resting and post-resting stages. The maximum sEMG amplitude and its rise time and recovery time during rapid contraction of pelvic floor muscles were recorded. Average sEMG amplitude and variability were also recorded during slow muscle contraction. The observations were correlated with the age. Results Significant differences among the 5 groups were found in all of the measurements. Spearman correlation analysis showed that age was positively correlated with the variation in the sEMG amplitudes in the pre-resting stage, with the rise time and with the recovery time. Age also correlated with the maximum sEMG amplitude in the rapid stage, the variation of the EMG amplitude in the slow-muscle stage, and the EMG amplitude in the post-resting stage. But it was negatively correlated with the average sEMG amplitude during pelvic floor contraction. Conclusions The stability and coordination of the pelvic floor muscles gradually deteriorates with age. The rate of activation and recovery become slower, with prolonged recruitment, slower response and poor excitability. |
