Purpose: The aim of this study was to report the improvement of Guillain-Barre syndrome after long-term combination treatment with Korean medicine.Methods: A patient was diagnosed with Guillain-Barre syndrome and treated with herbal medicine, acupuncture, pharmacopuncture, moxibustion, and exercise, including quadruped walking after three hospital admissions. To evaluate muscle strength and weakness, we measured manual muscle function, gait pattern, and the speed of quadruped walking.Results: The patient's muscle weakness in the extremities and gait stance were improved. The speed of quadruped walking was increased.Conclusion: We consider that combined treatment with Korean medicine might be effective for the muscle weakness of Guillain-Barre syndrome with a poor prognostic factor. To verify the effectiveness of this treatment, further research is needed.
