RoboHealth is a project that is focused on giving assistance to medical staff in order to improve the quality of treatment provided to patients in rehabilitation processes. The project covers two aspects during the rehabilitation process: assessment and therapy itself. In previous work [1], an automatic assessment system was presented for the evaluation of patient progress and effectiveness of the therapy, that is based on the Box and Blocks Test (BBT) of manual dexterity. In this article, an extension of the first trials including more participants is presented. This further advocates the use of automated methods in physical rehabilitation assessment.
