目的测试一种用于评价唇部功能的新型传感器。方法采用新型复合式传感器(CS)对20名健康受试者(女10名，男10名)的上唇轮匝肌肌电活动(OOM)、口内压力(IP)和嘴唇闭合压力(LP)进行同步记录。受试者完成了闭嘴、吹口和吸口的任务。用常规表面电极记录上下OOM的肌电活动，以评价CS电极的准确性。结果使用CS记录的整合肌电信号与传统OOM上电极记录的肌电信号高度相关(r=0.77±0.12，r=0.81±0.10，男性r=0.81±0.10)。与常规电极相比，CS电极的信噪比更高。在最大关闭嘴唇、吹气和吸吮过程中，女性的平均LP范围为2~6 kpa，男性为5~7 kpa。女性相应的IP分别为0.0±0.5、3.2±0.4和−4.4±2.6kPa.男性分别为−0.5±0 1.4、4.9±11.8和−5.6±2.8kPa.所有受试者对记录技术的评价均为优或良。结论CS记录OOM的肌电活动，操作简便、准确，可同时测量LP和IP。因此，它可以作为评价唇部功能的一种有效工具。
ObjectiveTo test a novel sensor for assessing lip function.MethodsThe electromyographic (EMG) activity of the upper orbicularis oris muscle (OOM), lip‐closing pressure (LP) and intraoral baro‐pressure (IP) were simultaneously recorded in 20 healthy subjects (10 women and 10 men) by using a novel composite sensor (CS). Subjects performed the lip‐closure, blow and suck tasks. EMG activity of the upper and lower OOMs was recorded using conventional surface electrodes to evaluate the accuracy of CS electrodes. The subjects also rated the user‐friendliness of the CS.ResultsIntegrated EMG signals recorded using the CS and conventional electrodes from the upper OOM were highly correlated (r= 0.77 ± 0.12 in women andr= 0.81 ± 0.10 in men). The signal‐to‐noise ratio was higher with the CS than with the conventional electrodes. The mean LP during maximum lip closure, blowing and sucking ranged between 2 and 6 kPa in women and between 5 and 7 kPa in men. The corresponding IPs in women were 0.0 ± 0.5, 3.2 ± 1.4 and −4.4 ± 2.6 kPa, respectively, and in men were −0.5 ± 1.4, 4.9 ± 1.8 and −5.6 ± 2.8 kPa, respectively. All subjects rated the recording technique as excellent or good.ConclusionThe CS was highly user‐friendly and accurate in recording the EMG activity of the OOM and could simultaneously measure the LP and IP. Therefore, it could be an effective tool for evaluating lip function.
