Connected healthcare devices, including medical equipments as well as personal health devices based on emerging mobile technologies used by healthcare providers and consumers, are expanding traditional means of practicing healthcare particularly physiotherapy services. We describe a system based on physiotherapy smart connected devices, as smart walker, smart crutches, force platform and natural user interface devices - characterized by different sensing technologies including piezorezistive force sensors and microwave radars. The information from the physiotherapy connected devices is stored and shared based on client-server architecture. Signals and metrics that combine the data from connected devices and serious games associated with physical rehabilitation are presented in the paper.
