Post-Trauma Acute Pain
Postoperative pain can be divided into acute pain and chronic pain, whereas acute pain is experienced immediately after surgery. Pain that lasts more than 3 months after an injury is considered to be chronic pain.
Over the years, several studies were conducted on LLLT and its effect on post-trauma acute pain in soft-tissue injury. 19 out of 22 controlled laboratory studies provide strong evidence that LLLT can modulate inflammatory pain by reducing levels of biochemical markers, neutrophil cell influx, oxidative stress, and formation of edema and hemorrhage in a dose-dependent manner.
In sum, these studies show that low-level laser therapy significantly reduces acute inflammatory pain.
