The aim of the study was to evaluate the effectiveness of transcutaneous electric nerve stimulation (TENS) for controlling pain after the archwire placement and then comparison between the placebo, extra-oral, and intra-oral group depending upon the electrode placement.
The study consists of a sample size of 90 patients who were further divided into three groups. Each group had 30 samples each, and the groups were divided into placebo group, extra-oral TENS group, and intra-oral TENS group. TENS application was done after the bonding and ligation of initial archwire. The patients were asked to record the level of pain on a VAS form at 4 hours, 8 hours, 12 hours, 24 hours, and 48 hours interval.
On comparison of VAS of all the three groups at 8 hours intervals significant result ( = 0.037) has occurred. Individual intra-group comparison has also shown some significant result.
TENS being a non-pharmacological, non-invasive method for controlling pain is found to be effective. Both the extra-oral and intra-oral applications are effective.
本研究的目的是评估经皮电刺激神经疗法(TENS)在控制弓丝放置后疼痛方面的有效性,并根据电极放置情况比较安慰剂组、口外组和口内组。
本研究样本量为90名患者,进一步分为三组。每组各有30个样本,分组为安慰剂组、口外TENS组和口内TENS组。在初始弓丝粘结和结扎后进行TENS治疗。要求患者在4小时、8小时、12小时、24小时和48小时间隔时,通过视觉模拟评分法(VAS)记录疼痛程度。
在8小时间隔时对所有三组的VAS进行比较,出现了显著结果(P = 0.037)。组内个体比较也显示出一些显著结果。
TENS作为一种控制疼痛的非药物、非侵入性方法,被发现是有效的。口外和口内应用均有效。
