The use of internet meant a revolution in the way of creating and using web applications. This movement helps democratizing virtual rehabilitation environments. There is also an emergence of new interaction devices such as Microsoft Kinect which allows user movement to be captured. So new approaches have appeared which facilitate the rehabilitation process.
Among all these news opportunities, physiotherapists are able to design postures or exercises through web applications. But when introducing web applications in virtual rehabilitation environments for the design of postures new factors have to be taken into account. The creation of such a postures may be complicated, involving a wide number of actions. If the physiotherapist does not feel comfortable using the rehabilitation system, it becomes cumbersome and hard to use.
In this work we introduce new characteristics to improve the design of postures in rehabilitation environments. We use local storage in a virtual rehabilitation environment based on the web to measure how it improves usability and satisfaction.
