This master thesis deals with the development of the design proposal, Peak, for measuring functionality and movement quality in physiotherapy rehabilitation processes.

There are a large amount of scientific research on the topic ‘phy-
siotherapy’, and the treatment methods within physiotherapy. However, there are currently little development of more modern assessment tools for the consultation that uses this knowledge in combination with new technology. The fast growing knowledge and development of the field of technology keep giving new possibilities in relation to using the technology in clinical pro-
ducts. This leads to the development of the design proposal; Peak.

Peak is a system that by using motion tracking technology can contribute to provide the physiotherapists with accurate objective data on the functionality of the client’s concerning injury (measured in range of motion). This data is converted into velo-
city, acceleration, and jerkiness, as the first product targeted the market for physiotherapy. These parameters contribute to the clinical picture regarding the quality of movement. Peak provides accurate digital objective data mediated through an application in favor of the physiotherapists, the clients, and the insurance companies.
