Transcutaneous Electrical Nerve Stimulation (TENS) In Chronic Low Back Pain Management: Principles, Applications, And Future Directions

Abstract

TENS represents a non-invasive and cost-efficient approach to alleviating chronic lower back pain, providing a viable alternative to pharmaceutical treatments. This article explores the principles, applications, and effectiveness of TENS in managing chronic lower back pain. TENS operates by delivering painless electrical currents to activate nerves beneath the skin's surface, providing flexible and customizable pain relief. It has shown promise in reducing reliance on nonsteroidal anti-inflammatory drugs (NSAIDs) and opioids, thus mitigating potential side effects associated with prolonged medication use. However, the long-term efficacy of TENS remains a subject of debate, and individual differences may influence its effectiveness. This article reviews the existing literature, highlighting the positive impact of TENS on short-term pain relief, especially in the context of lower back pain. Additionally, it discusses variations in research quality and methodology, emphasizing the need for larger-scale trials and personalized treatment plans to enhance its long-term effectiveness. In summary, TENS demonstrates considerable promise as a safe and non-invasive therapeutic choice for addressing chronic lower back pain. While questions remain regarding its long-term efficacy, TENS offers an alternative for patients seeking pain relief without the side effects associated with medication. Future research should focus on personalized approaches and comprehensive studies to further elucidate its role in chronic pain management and improve patients' quality of life.
