This double-blind randomized controlled pilot study evaluated the efficacy of intravenous laser irradiation of blood (ILIB) therapy in 22 patients with ischemic stroke. The ILIB group demonstrated significant improvements in Stroke Impact Scale scores at 3 months (p = 0.019), Fugl-Meyer assessment-Motor Function scores at 3 days and 3 months (p = 0.003 and p = 0.022), and 6-minute walking test performance at 3 days (p = 0.018) compared to the control group.
Key findings
- ILIB group had significantly better SIS scores at 3 months (p = 0.019).
- FMA-MF scores were significantly higher in the ILIB group at 3 days and 3 months (p = 0.003 and p = 0.022).
- 6-MWT performance was significantly better in the ILIB group at the 3-day follow-up (p = 0.018).
Why it matters
The findings suggest that ILIB therapy may enhance functional recovery in ischemic stroke patients, potentially offering a new adjunctive treatment option to improve patient outcomes.
