Cell Glow recommends: Do not buy an RLT panel expecting it to cure low back pain on its own. If you also want RLT for a broader home routine, you can illuminate the lower back, but have persistent or radiating pain assessed first.
What does the research say?
A systematic review of twelve randomized trials found no clinically significant difference in pain or functioning compared to sham treatment. A large, separate study on chronic non-specific back pain also found no benefit over a placebo. The techniques studied ranged from lasers to LEDs; consequently, any results cannot be directly attributed to a specific home-use panel.
When might it still be worth discussing?
Some people appreciate a light therapy session as part of a relaxation routine. That is different from a proven treatment addressing the underlying cause. If symptoms persist, a doctor or physiotherapist can help distinguish between issues such as muscle strain, nerve irritation, and other causes. Treat any new loss of function, loss of sensation, or problems with urination as urgent matters.
How do you make a choice?
If you already own a device, use it strictly according to the manual and track its effect on both pain levels and daily activities. Do not opt for higher power settings or longer sessions in the hope of boosting the effectiveness of an unproven back treatment. The outcome that matters is improved functioning, not just a pleasant sensation of warmth or light.
