Photobiomodulation for Lower Back Pain Post Spinal Fusion and Decompression Surgery
After spinal fusion and decompression surgery there is a possible risk of developing chronic back pain. After surgery there is typically inflammation around the operation site and this inflammation can be painful and debilitating to patients.

Many possible treatment plans have been incorporated to assist the patient with recovery - notably medications, physical therapy, and braces. However, few studies have looked at laser diodes that utilize high-power laser lights that are aimed at decreasing pain and inflammation. Investigators aim to look compare patients using a back brace with laser diodes within versus those who wear a normal brace used as a placebo. Investigators will also assess the patient's surgical wound to monitor the progression of wound healing while using the brace.
