To examine the hypothesis of disturbed autonomic function, non-invasive cardiovascular reflex tests were performed on 11 sleep bruxists in the waking state. The tests included the Valsalva manoeuvre, a deep-breathing test, and an orthostatic test (standing up). The R-R intervals were monitored continuously, and blood pressure was measured non-invasively and continuously using the Finapres method. In total, 64% of bruxists showed abnormalities in at least two variables reflecting the cardiovascular autonomic function. Abnormalities were found in blood pressure regulation during the Valsalva strain, and in the immediate biphasic heart rate response during standing up, but not in the vagally mediated deep-breathing difference. These findings suggest that bruxism is accompanied by abnormalities in autonomic function, particularly in sympathetic vasoconstrictor function.
为检验自主神经功能紊乱的假说，对11名清醒状态下的睡眠磨牙症患者进行了非侵入性心血管反射测试。测试包括瓦尔萨尔瓦动作、深呼吸测试和直立测试（站立）。连续监测R-R间期，并使用Finapres方法无创连续测量血压。总体而言，64%的磨牙症患者在反映心血管自主神经功能的至少两个变量中表现出异常。在瓦尔萨尔瓦动作用力时的血压调节以及站立时即刻的双相心率反应中发现了异常，但在迷走神经介导的深呼吸差异中未发现异常。这些发现表明，磨牙症伴有自主神经功能异常，尤其是交感缩血管功能异常。
