In this study feasibility of the MeDiNa concept is looked at, which means telemedical services for homely rehabilitation. With the help of microsystems technology, the relevant vital signs are measured at the patient`s home, then transmitted to the MeDiNa- Homebox- Tablet PC (by bluetooth) and then transferred into a central database, the MeDiNa eHealth- portal (by HSDPA, UMTS). These parameters can be continuously monitored by authorized network participants such as the family doctor or the patients themselves. In future, beyond cost advantages this will help to supervise risk patients or inspire patients to take more care of their health during homely rehab.
