<![CDATA[Background: Osteoarthritis (OA) is a musculoskeletal disorder which is a progressive change in joints that is slow and intermittent, usually in the field there are exercises to strengthen muscles which are only supported by the agonist muscles while the antagonistic muscles also participate and even more dominant, the most approved intervention to be able to activate both muscles is a special task. The purpose of this study is to study whether there are functional requirements for specific tasks to improve the functioning and running of osteoarthritis patients.Subjects and Method: This study method uses the type of experimental research with a single case research method using A-B-A research design. The study was conducted in January 2020 located at the University of Muhammadiyah Surakarta. A patient with knee OA was selected using consecutive sampling. Functional ability and walking speed were tested by West Ontario and McMaster Osteoarthritis Index (WOMAC).Results: Specific training improved physical function and speed walking in patients with knee osteoarthritis. There was no effect of specific training on pain and stiffness.Conclusion: Task specific training improves functional ability and walking performance in aptient with knee osteoarthritis.Keywords: Osteoarthritis, task specific training, visual surface electromyograph, augmented feedback, functional ability.Correspondence: Suryo Saputra Perdana.
