Myofascial pain syndrome of the pelvic floor (MPSPF) is a common disease in the context of chronic pelvic pain (CPP); however, there is currently no gold-standard test to diagnose it.
To validate the turns-amplitude analysis (TAA) as a diagnostic test for MPSPF in patients with CPP.
A case-control study was performed, and patients were consecutively sampled within a specified period of time. A total of 128 patients were included: 64 patients with CPP (32 men and 32 women) and 64 control patients (32 men and 32 women). The same operator conducted all tests. Electromyography of the TAA is based on the collection of motor unit potentials that measure the number of changes in the signal and the mean amplitude of the changes. The electromyogram transfers the data to a graphical point cloud, which enables the patient's results to be compared with the results of the healthy subjects.
In patients and control subjects, the sensitivity and specificity of the proposed diagnostic test showed a marked clinical significance: the sensitivity was 83%, and the specificity was 100%. A positive predictive value of 1 (95% CI 1 to 1) and a negative predictive value of 0.85 (95% CI 0.77 to 0.93) were observed.
TAA is a reliable diagnostic test to detect MPSPF. Further studies are needed to reproduce these results.
盆底肌筋膜疼痛综合征（MPSPF）是慢性盆腔疼痛（CPP）中的一种常见疾病；然而，目前尚无诊断该病的金标准检测方法。
验证转角-幅度分析（TAA）作为CPP患者MPSPF诊断试验的有效性。
进行了一项病例对照研究，在特定时间段内连续对患者进行抽样。共纳入128例患者：64例CPP患者（32例男性和32例女性）和64例对照患者（32例男性和32例女性）。所有检测均由同一名操作人员进行。TAA的肌电图基于运动单位电位的采集，该电位测量信号变化的数量和变化的平均幅度。肌电图将数据转换为图形点云，从而能够将患者的结果与健康受试者的结果进行比较。
在患者和对照受试者中，所提出的诊断试验的敏感性和特异性显示出显著的临床意义：敏感性为83%，特异性为100%。观察到阳性预测值为1（95%CI 1至1），阴性预测值为0.85（95%CI 0.77至0.93）。
TAA是检测MPSPF的可靠诊断试验。需要进一步研究以重现这些结果。
