Full body motion capture (MoCap) plays an increasingly im-portant role in many fields from entertainment to medicine. How-ever, accurate motion capture systems have not been used in some application areas due to reasons like cost, inflexibility and complexity of operation. We developed a complete marker based optical MoCap system, which targets these issues. In this paper we describe how a flexible calibration method, robust skeleton tracking and interfaces to third party software have been devel-oped. To demonstrate robustness, reliability and accuracy, our system has been successfully employed to provide input to a serious game targeting rehabilitation of patients with chronic pain of the lower back and neck, a group that has previously been neglected by serious games. A brief overview of the application and preliminary results of a medical evaluation with chronic pain patients is provided.
