TENS Treatment Plus Ibuprofen for the Treatment of Acute Back Pain in the ED

Low Back Pain Clinical Trial

Official title: Double-blind, Randomized, Placebo Controlled Trial of Transcutaneous Electrical Nerve Stimulation (TENS) Treatment Plus Ibuprofen for the Treatment of Acute Back Pain in the Emergency Department

Status Withdrawn

Clinical Trial Summary

Patients presenting to the ED with a chief complaint of acute low back pain and whom the providing physician feels symptomatic treatment is appropriate in the ED will be screened for inclusion in the study. The purpose of the study is to compare Transcutaneous Electrical Nerve Stimulation (TENS) as an adjunct to ibuprofen in the treatment of acute low back pain in the emergency department. Therefore, the aim of this prospective, randomized, double blind study is to evaluate the efficacy of ED administered TENS in acute low back pain patients during their ED visit.

Clinical Trial Description

The study is a double blind, randomized, placebo controlled trial. One group will receive ibuprofen and TENS. The comparison group will receive ibuprofen and sham TENS. The study primary endpoint is change in pain level on Visual Analog Scale score at 45-60 minutes after TENS start.

This is a two-arm, double blind, randomized control trial evaluating the patient perceived improvement in back pain. Patients will first fill out a Visual Analog Scale (VAS).

Patients will be randomized to one of two arms. Ibuprofen 800 mg, plus sham TENS for 45 minutes Ibuprofen 800 mg, plus TENS for 45 minutes

Patients will be given a 2nd VAS scale up to 15 minutes after the end of the TENS session. After the second VAS the patients will be finished with the study procedures and can be continued to be cared as per the discretion of their treating physician.

Our intention is to detect a 20% reduction in pain by VAS with a common standard deviation equal to the difference at the p = 0.05 level with a power of 80% using an analysis of variance (ANOVA). The calculated sample size required 28 patients per group. Considering the uncertain dropout rate, the investigators decided to enroll at least 66 patients. Baseline characteristics will be calculated to determine if groups are equal. A two-way repeated-measures ANOVA will be used to test both a trial effect and a group effect (SPSS 20, SPSS Inc., Chicago, IL). Data will be presented as means with standard deviations with 95% confidence intervals. A p< 0.05 was considered statistically significant. ;
