In order to examine the effect of an occlusal splint on the integrated electromyography (EMG) of the masticatory muscles, EMG of bilateral masseter muscles of 23 patients with temporomandibular joint disturbance syndrome (TMJDS), with and without an occlusal splint, was measured and integrated on line during maximum clenching. It was found that the integrated myoelectrical value of the masseter muscle on the involved and non-involved side was reduced with the occlusal splint. The absolute difference between integrated myoelectrical values in the left and right masseter muscles was reduced with an occlusal splint, but the relative difference remained virtually unchanged. These results indicate that the occlusal splint can decrease masseter muscle activity and thus exert a therapeutic effect.
为了研究咬合板对咀嚼肌积分肌电图（EMG）的影响，对23例颞下颌关节紊乱综合征（TMJDS）患者双侧咬肌在佩戴和不佩戴咬合板的情况下进行最大紧咬时的EMG进行测量并在线积分。结果发现，佩戴咬合板时，患侧和非患侧咬肌的积分肌电值均降低。咬合板使左右咬肌积分肌电值的绝对差值减小，但相对差值基本不变。这些结果表明，咬合板可降低咬肌活动，从而发挥治疗作用。
