This paper shows the general concept and the primary implementation of a pervasive intelligent system for rehabilitation. The scope of this work is to highlight the possibility to join two important research fields, i.e. rehabilitation and ambient assisted living, to enhance the capabilities and independence of disable and aged people. The described system was composed of a ZigBee network, with coordinator, sensor and actuator nodes, able to identify and control patient's activities and send warning to caregiver if requests in warning functionality, and of a software interface to manage the whole network and to monitor patient in outdoor environment
