Stroke is the leading cause of disability in the United States. Hemiparesis, affecting the majority of the subjects, leads to other related process like learned non-use, which compromises the affected individual's functionality. Many current therapy techniques do not incorporate new research which point towards involvement of both arms in a synchronous, bimanual but decoupled environment to achieve maximum recovery. A novel method of robotic therapy, using position based cues, was tested on able-bodied individuals with strong handed preferences as a model for stroke survivors with severe arm bias due to learned non-use, to verify the effectiveness in assessing and changing in the short term their hand preference. The reduction in non-dominant arm error in a significant number of subjects shows this method can be used as a useful model for future therapy techniques using robotic systems.
