Background and Objective: Previous clinical studies have shown that Neuroaid (MLC 601) may be beneficial in post-stroke rehabilitation. Our aim was to investigate the efficacy of Neuroaid on motor recovery in ischemic stroke patients using rehabilitation endpoints in accordance with the International Conference on Harmonization/Good Clinical Practice guidelines, in order to provide predictive information for further larger trials. Methods:This is a phase II double-blind, placebo-controlled pilot study of 40 subjects admitted with a recent (less than 1 month) ischemic stroke. All subjects were given either Neuroaid or placebo, 4 capsules 3 times a day for 4 weeks. Fugl-Meyer Assessment (FMA), National Institutes of Health Stroke Scale and Functional Independence Measure scores were measured at initiation of the treatment, and at 4 and 8 weeks. Results: None of the outcomes was statistically significant between the two groups. However, FMA scores showed a positive trend for improvement with Neuroaid treatment over time. Subgroup analysis of subjects with posterior circulation infarction and severe stroke both showed a tendency for better recovery. Conclusion: Some positive trends were observed in the Neuroaid group. A larger multicenter trial focusing on severe stroke patients is needed to better evaluate the role of Neuroaid in aiding stroke recovery in rehabilitation. Copyright (c) 2009 S. Karger AG, Basel.
