To co mpare the e ffica cy of transcutaneous elec trica l ner ve stimulation with commercially ava ilab le analgesics in alleviating symptoms of temporomandibular disorders.
The cross-sectional, interventional study was conducted from March 11, 2020, to August 31, 2023, at the Oral and Maxillofa cial S urger y Department of the Armed Forces Institute o f Den tist r y, Rawalpindi, Pakistan, and comprised patients aged 18-65 years who were experiencing pain or distress in the temporomandibular joint region. The par ticipants were divided into intervention group A and control group B. Group A treatment involved applying electrodes near the temporomandibular joint, with parameters adjusted as per the treatment guidelines. Group B subjects received only analgesics along with basic care recommendations. Pain intensit y was assessed using visual analogue scale, while functional impairment and adverse effects were monitored. Data was analysed using SPSS 24.
Of the 130 patients initially assessed, 100(77%) were included; 50(50%) in each group. In group A, there were 33(66.0%) fema les and 17(34.0 %) male s wit h overal l mean age 42.8±10.12 years. In group B, there were 30(60%) females and 20(40%) males with overall mean age 46.98±14.09 years. Pain intensity was significantly lower in group A compared to group B post-inter vention (p=0.009). Group A sub jec ts also showed significant post-intervention improvement in terms of mouth opening compared to group B patients (p<0.05). There was no significant intergroup difference with respect to adverse effects (p>0.05).
Transcutaneous electrical nerve stimulation was significantly more effective than commercially available analgesics in alleviating symptoms of temporomandibular disorders.
比较经皮电神经刺激与市售镇痛药在缓解颞下颌关节紊乱症状方面的疗效。
本横断面、干预性研究于 2020 年 3 月 11 日至 2023 年 8 月 31 日在巴基斯坦拉瓦尔品第武装部队牙科研究所口腔颌面外科进行，纳入年龄在 18-65 岁之间、颞下颌关节区域疼痛或不适的患者。将参与者分为干预组 A 和对照组 B。A 组治疗方法为在颞下颌关节附近放置电极，根据治疗指南调整参数。B 组患者仅接受镇痛药和基本护理建议。使用视觉模拟评分法评估疼痛强度，同时监测功能障碍和不良反应。数据使用 SPSS 24 进行分析。
最初评估的 130 例患者中，有 100 例（77%）入选，每组 50 例。A 组中，女性 33 例（66.0%），男性 17 例（34.0%），平均年龄 42.8±10.12 岁。B 组中，女性 30 例（60%），男性 20 例（40%），平均年龄 46.98±14.09 岁。干预后，A 组疼痛强度明显低于 B 组（p=0.009）。与 B 组患者相比，A 组患者干预后张口度明显改善（p<0.05）。两组不良反应无显著性差异（p>0.05）。
经皮电神经刺激在缓解颞下颌关节紊乱症状方面明显优于市售镇痛药。
