Curr Pain Headache Rep. 2023 Oct;27(10):607-613. doi: 10.1007/s11916-023-01149-8. Epub 2023 Aug 14.

Abstract

Purpose of review: An analysis of data conducted in 2015 by the National Health Interview Survey (NHIS) found that an estimated 25.3 million adults (11.2%) have experienced pain every day for the preceding 3 months, and nearly 40 million adults (17.6%) have experienced a severe level of pain.

Recent findings: Multiple reviews have analyzed the current management of acute pain; however, much of the current literature only focuses on pharmacological methods of analgesia, such as opiates, ketamine, or non-steroidal anti-inflammatory drugs (NSAIDs). Publications that discuss non-pharmacological options often criticize the limitations of available research for these therapies, making further exploration of this type of treatment necessary. The present investigation aims to summarize current knowledge on the use of low-level laser therapy (LLLT), a cold laser non-pharmacological approach, in managing acute pain and to discuss important clinical findings and considerations when it comes to utilizing this treatment option in patients.

Keywords: Acute pain; Anti-inflammatory; Low-level laser therapy; Non-pharmacological analgesic; Photo-radiation.
