摘要

目的：

探讨不同频次针刺治疗颞下颌关节紊乱病（TMD）疼痛的疗效差异。

方法：

将42例TMD疼痛患者随机分为低频次组、中频次组、高频次组，每组14例。各组均采用针刺治疗，取穴双侧合谷、阳陵泉及患侧听宫、颊车、下关，每次30 min。低频次组每周针刺1次，中频次组每周针刺2次，高频次组每周针刺3次，均治疗4周。分别于治疗前后和治疗结束后4周随访比较各组患者慢性疼痛量表（GCPS）、视觉模拟量表（VAS）、下颌功能受限量表-20（JFLS-20）评分和压力疼痛阈值（PPT）。

结果：

治疗后，各组患者GCPS和JFLS-20评分均较治疗前降低（

0.05），高频次组和中频次组患者VAS评分较治疗前降低（

0.05），高频次组患者各部位PPT较治疗前升高（

0.05）；高频次组患者GCPS、JFLS-20及VAS评分低于中频次组和低频次组（

0.05），部分PPT高于中频次组

和低频次组（

0.05）。随访时，各组患者GCPS、JFLS-20及VAS评分均较治疗前降低（

0.05），高频次组和中频次组患者各部位PPT均较治疗前升高（

0.05）；高频次组GCPS、JFLS-20及VAS评分低于低频次组和中频次组（

0.05），各部位PPT高于低频次组和中频次组（

0.05）。

结论：

每周针刺3次在改善TMD疼痛强度方面优于每周针刺1次和每周针刺2次，并可缓解一部分下颌功能障碍，其疗效可持续到治疗结束后4周。

Abstract

Objective

To explore the efficacy differences among different acupuncture frequencies for pain of temporomandibular disorders (TMD).

Methods

A total of 42 patients with TMD pain were randomly divided into a low-frequency group

a medium-frequency group

and a high-frequency group

with 14 patients in each group. All groups received acupuncture treatment at bilateral Hegu (LI4) and Yanglingquan (GB34)

as well as ipsilateral Tinggong (SI19)

Jiache (ST6)

and Xiaguan (ST7)

with each session lasting 30 minutes. The low-frequency group received acupuncture once per week

the medium-frequency group received acupuncture twice per week

and the high-frequency group received acupuncture three times per week

for a total duration of four weeks. The graded chronic pain scale (GCPS) score

visual analogue scale (VAS) score

jaw functional limitation scale-20 (JFLS-20) score

and pressure pain threshold (PPT) were assessed in the three groups before and after treatment

as well as at the four-week follow-up after treatment completion.

Results

Compared before treatment

GCPS and JFLS-20 scores were significantly decreased in all the groups after treatment (

0.05)

and VAS scores were significantly decreased in the high-frequency and medium-frequency groups (

0.05)

PPT values at different measurement sites were increased significantly in the high-frequency group (

0.05). After treatment

GCPS

JFLS-20

and VAS scores in the high-frequency group were lowe

r than those in the medium-frequency and low-frequency groups (

0.05)

while some PPT values were higher than the other two groups (

0.05). At follow-up

GCPS

JFLS-20

and VAS scores remained significantly lower in all the groups compared to baseline (

0.05)

PPT values were increased significantly in the high-frequency and medium-frequency groups (

0.05)

with the high-frequency group showing lower GCPS

JFLS-20

and VAS scores and higher PPT values compared to the other two groups (

0.05).

Conclusion

Acupuncture three times per week is more effective in reducing TMD pain intensity compared to once or twice per week

and can also alleviate some mandibular functional impairments. The therapeutic effects persist for at least four weeks after treatment completion.
