Background and Study Aim. While many persons who participate in Budo-based rehabilitation profess improvements in functional ability, and selfefficacy in daily life, it has been extremely difficult to collect quantitative scientific data on the effectiveness of Budo-based rehabilitation. This difficulty is due in part to the wide variety of disabilities. The aim of this present study, therefore, is the scientific data on the effects of Budo rehabilitation targeting post-stroke patients.Material and Methods. The six post-stroke patients were subjected to a period of 4-months Budo practice. Participant data was measured according to Single Subject Experimental Design guidelines. The following tests were used to gather data: 5 repetitions of the sit-to-stand test, 6 meter timed walk test, and Test of Dynamic standing balance. Data was also collected through interviews and self-report regarding: fear of fallingand general health.Results. Data showed that post-stroke patients experienced improved muscle strength, balance, postural control, walking ability and performance of daily activities as a result of the Budo-based rehabilitation in this experiment. Patient self-reporting revealed a reduced fear of falling and indications of a healthier self-image as a result of Budo practice. Patient interviews suggest that the sociality and culture of Budo had a powerfully positive psychological effect aiding the rehabilitative process.Conclusion. Data clearly showed that Budo-based rehabilitation effectively delivered general quantitative improvements as reported by poststroke patients. Not only could the patients perform daily-life tasks better, they exhibited less fear, more self-efficacy, and a healthier self-image.
