This systematic review and meta-analysis evaluated the effects of photobiomodulation (PBM) on pain relief and functional improvement in patients with fractures. The analysis included 9 randomized controlled trials. PBM significantly reduced pain scores at one week (MD -0.74, 95% CI -1.00, -0.47, p < 0.0001) and improved grip strength at four weeks (MD 5.03, 95% CI 4.29, 5.78; p < 0.0001), but showed no long-term benefits.
Key findings
- PBM reduced pain scores at one week compared to placebo (MD -0.74, 95% CI -1.00, -0.47, p < 0.0001).
- Grip strength improvement at four weeks was significantly greater in the PBM group (MD 5.03, 95% CI 4.29, 5.78; p < 0.0001).
- No significant differences in pain and functional scores were observed at 4-26 weeks.
- Bone healing outcomes were inconsistent between PBM and placebo groups.
Why it matters
Understanding the efficacy of PBM in managing pain and enhancing recovery in fracture patients can inform treatment strategies. While PBM shows promise for short-term pain relief and grip strength improvement, its long-term benefits remain uncertain.
