Treatment of Acute Low Back Pain With Transcutaneous Electrical Neurostimulation in Emergency Departments

Treatment of Acute Low Back Pain With Transcutaneous Electrical Neurostimulation in Emergency Departments: a Randomised Controlled Trial

Acute low back pain is a common reason for emergency department visits (4.39% [95% CI: 3.67-5.18]). Drug treatment options are limited and largely ineffective. Paracetamol and opioids are no better than placebo for acute low back pain. Only NSAIDs and muscle relaxants have a slightly beneficial effect on pain, but muscle relaxants have an unfavorable benefit-risk ratio.

Given this situation, it is necessary to explore new non-pharmacological treatment options to relieve the pain of these patients. Transcutaneous electrical nerve stimulation (TENS) is a non-pharmacological therapy that involves applying an electrical current through the skin. Using one or two pairs of electrodes attached to the skin, TENS delivers painless, low-intensity electrical pulses to a painful area or along the path of a nerve.

TENS works by selectively activating large-diameter, non-nociceptive afferent fibers to induce segmental analgesia. In addition, TENS increases the concentration of endorphins in the bloodstream and cerebrospinal fluid.

The use of TENS has been studied primarily in chronic low back pain. A 2007 Cochrane systematic review concluded that TENS appears to reduce pain and improve range of motion in subjects with chronic low back pain.

The use of TENS in the emergency department has been little studied. To our knowledge, there are no high-quality studies comparing TENS versus placebo for acute low back pain in patients presenting to an emergency department. This study aims to investigate the analgesic efficacy of TENS compared to placebo in the treatment of acute low back pain in the emergency department.

研究衡量的是什么?

主要结果指标

结果测量
措施说明
大体时间
Comparison of the proportion of patients experiencing a >30% reduction in their initial pain after 30 minutes of treatment.
大体时间:From enrollment to the end of treatment at 30 minutes

Pain is quantified using the EN numerical pain scale ranging from 0 (no pain present) to 10 (maximum pain). This is a self-assessment scale for the patient.

The patient's pain level (according to EN numerical pain scale) is assessed at enrollment (Time 0) before the medical device is placed. A pain assessment using this scale is requested after 15 and 30 minutes.

From enrollment to the end of treatment at 30 minutes
