Abstract

The effect of Microcurrent Electrical Nerve Stimulation (MENS) was evaluated and compared with occlusal splint therapy in temporomandibular disorders (TMD) patients with muscle pain. Twenty TMD patients were divided into four groups. One received occlusal splint therapy and MENS (I); other received splints and placebo MENS (II); the third, only MENS (III) and the last group, placebo MENS (IV). Sensitivity derived from muscle palpation was evaluated using a visual analogue scale. Results were submitted to analysis of variance (p<0.05). There was reduction of pain level in all groups: group I (occlusal splint and MENS) had a 47.7% reduction rate; group II (occlusal splint and placebo MENS), 66.7%; group III (MENS), 49.7% and group IV (placebo MENS), 16.5%. In spite of that, there was no statistical difference (analysis of variance / p<0.05) between MENS and occlusal splint therapy regarding muscle pain reduction in TMD patients after four weeks.

摘要

对微电流神经刺激(MENS)的效果进行了评估,并与咬合板疗法在患有肌肉疼痛的颞下颌关节紊乱病(TMD)患者中进行了比较。20名TMD患者被分为四组。一组接受咬合板疗法和MENS(I组);另一组接受咬合板和安慰剂MENS(II组);第三组仅接受MENS(III组),最后一组接受安慰剂MENS(IV组)。使用视觉模拟量表评估源自肌肉触诊的敏感性。结果进行方差分析(p<0.05)。所有组的疼痛水平均有所降低:I组(咬合板和MENS)的降低率为47.7%;II组(咬合板和安慰剂MENS)为66.7%;III组(MENS)为49.7%,IV组(安慰剂MENS)为16.5%。尽管如此,四周后,在TMD患者的肌肉疼痛减轻方面,MENS与咬合板疗法之间没有统计学差异(方差分析/p<0.05)。
