pStroke is a serious burden for the health system and the
affected individuals. Globally, around 16 million people per year
experience a stroke for the first time, of which 5 million remain
limited in their functionality and participation. Since
improvements in functionality after a stroke take time and require
many repetitions during exercises, intensive therapy is often
necessary. On the other hand, efficiency will be one of the key
factors to keeping control of health care costs.
The project team will build upon the existing knowledge and experience of the Zurich University of Applied Sciences, rotavis AG, and Bitforge AG as well as a clinical partner (Clinic Valens). We will develop an augmented
reality (AR) training system that allows patients to perform their reaching and trunk control exercises on their own while being supervised by AR technology and being motivated and guided by therapeutic AR games. In addition, the system will be able to challenge the patients’ trunk control with a movable 3-D seat, and monitor improvements over time. The system is intended to be used in the clinic and at a later stage at home. The key technological challenges are the tracking of hand movement with enough sensitivity to distinguish between different types of grip, the design of the AR environment according to stroke patients’ needs and the integration of the two parts of the system, the AR technology and the movable 3-D seat. We will identify the precision required for the intended use and identify the right technology to address these challenges.
The key business challenge is to keep the costs of the technological components low. While the number of stroke patients is immense, the actual therapy costs need to be low. Yet the use of today’s commodity technology will allow implementing a cost effective system that can be brought to market. The business potential for this system is high as it can target a wide range of clinics and rehabilitation centres.
