RCT of laser acupuncture in acute low back pain.

This study is testing whether laser acupuncture (acupuncture using a low-intensity laser instead of needles) can help relieve acute low back pain. Acute low back pain is one of the most common reasons people visit their doctor or go to the emergency department. Researchers will compare laser acupuncture to a placebo treatment over a 12-month follow-up period to find out if it provides real benefits. You may be eligible if: - You are between 20 and 60 years old - You have had back pain for between 2 and 8 weeks You may NOT be eligible if: - Your back pain is long-standing (chronic) - You have a significant medical condition that might affect your participation Talk to your doctor about whether this trial might be right for you.
