Stroke, technology-supported rehabilitation, usability, sensors, feedback.
We report on an explorative user test of a Rehabilitation Exerciser in an early phase of development. The main question was if stroke patients were able to work with the rehabilitation system independently? Fifteen patients came into the clinic, put on movement tracking sensors, and did three rehabilitation exercises using this system. After these exercises, patients were given two usability questionnaires and given an interview about ease/difficulty of sensor placement and feedback features. Finally, patient videos were viewed to note all patient errors. The results were positive: patients were able to perform the actions needed to put on the sensors. They were also fairly capable of interacting with the system independently. Few errors were made. Ease of use and learning were good, but satisfaction and information quality was less presumably due to lack of actionable feedback. The results are extremely valuable for further user-centered development of the system.
