Objective.本研究的目的是验证一个小型的电子肌电图设备（BiteStrip），旨在筛选咬肌肌电图事件，表明睡眠磨牙症（SB）对传统的咬肌肌电图事件（MEMG）。6例SB寻求治疗的患者，4例阻塞性睡眠呼吸暂停（OSA）患者和8例无阻塞性睡眠呼吸暂停的对照者，接受了夜间多导睡眠图，包括MEMG和BiteStrip记录。根据总记录时间（TRT）和总睡眠时间（TST）计算总BiteStrip和MEMG评分和指数（每小时事件数）。测量准确性、斯皮尔曼rho相关性和非参数组间比较。BiteStrip平均灵敏度为0.72，平均阳性预测值为0.75。左侧BiteStrip与MEMG总分、TRT和TST指数之间的相关性分别为r = 0.81、r = 0.79和r = 0.79。Bland-Altman图显示指数之间具有良好的一致性。两组患者的总分和各项指标差异有统计学意义。BiteStrip和MEMG评分显示出很强的相关性。敏感性和阳性预测值是可以接受的。BiteStrip是一种可行的筛选器，用于识别提示SB的咬肌肌电事件。
Objective. The aim of this study was to validate a small electronic electromyographic device (BiteStrip) designed to screen masseter electromyographic events that indicate sleep bruxism (SB) against traditional masseter electromyographic events (MEMG).Study design. Six SB treatment-seeking patients, 4 obstructive sleep apnea (OSA) patients and 8 symptom-free controls, underwent overnight polysomnography, including MEMG and BiteStrip recordings. Total BiteStrip and MEMG scores and indices (events per hour) based on total recording time (TRT) and total sleep time (TST) were computed. Measures of accuracy, Spearman's rho correlations, and nonparametric group comparisons were performed.Results. BiteStrip average sensitivity was 0.72, average positive predictive value was 0.75. Correlations between left BiteStrip and MEMG total scores, TRT, and TST indices were r = 0.81, r = 0.79, and r = 0.79, respectively. Bland-Altman plots showed good agreement between indices. Significant group differences were observed for total scores and indices.Conclusions. BiteStrip and MEMG scores showed strong relationships. Sensitivity and positive predictive value were acceptable. The BiteStrip is a viable screener for identifying masseter electromyographic events that indicate SB.
