Objectives: Strokes have diverse symptoms and signs. One of ten stroke patients has chronic pain after a stroke. Pain after a stroke interrupts rehabilitation and worsens quality of life, but there is no efficient treatment for this pain. This study surveyed and reports on the clinical studies of treatment for chronic pain after a stroke. Methods: We searched journals for reports on clinical studies of treatment for chronic pain after a stroke through the databases OASIS (http://oasis.kiom.re.kr), NDSL (ndsl.kr), Kmbase (http://kmbase.medric.or.kr/), and PubMed (http://www. pubmed.com). The search words were "stroke & pain", "jungpung中風 & pain", "pungbi風痺", "cerebral hemorrhage & pain", and "cerebral infarction & pain". Results: Twenty-nine studies of treatment for chronic pain after a stroke were found. Of these, 15 were randomized controlled trials, 10 were nonrandomized controlled trials, and 4 were "before and after" studies. Treatments were diverse, including acupuncture, electroacupuncture, herbal acupuncture, herbal medicine, and more. The treatment periods were longer than 3 weeks on average. Conclusions: These results show that good quality randomized controlled trials of treatment for chronic pain after a stroke are small in number. We need larger and more diverse studies of treatment for chronic pain after a stroke.
