The current work describes a methodology to automatically detect the severity of bradykinesia in motor disease patients using wireless, wearable accelerometers. This methodology was tested with cross validation through a sample of 20 Parkinson's disease patients. The assessment of methodology was carried out through some daily living activities which were(More)
Current trends in healthcare technology include mobile-based applications. Relevant advances in the integration of vital signs monitoring devices with mobile platforms are widely reported nowadays. In this context, conceiving and designing an interoperable application is essential due to the growing necessity of integrating a huge and heterogeneous amount(More)
A mobile electrocardiogram (ECG) transmission system was developed which could transmit single-lead ECG data via GSM mobile telephony. Ambulance transmission trials comprised a total of 72 communications, of which 94% were successful. The system was able to redial up to a predetermined number of times until the GSM call was re-established (during the trials(More)

We have developed a system for supporting people with special needs. It allows remote monitoring of electrocardiographic and other signals together with multimode environmental control. The multimodal approach allows users with disabilities to interact more with the home environment. Telemedicine devices were integrated into the system to provide a link to(More)
Centralized testing demands costly laboratories, which are inefficient and may provide poor services. Recent advances make it feasible to move clinical testing nearer to patients and the requesting physicians, thus reducing the time to treatment. Internet technologies can be used to create a virtual laboratory information system in a distributed health-care(More)
During the last years a transition from desktop computers and fixed phones to nomad devices such as mobile phones, palmtops and mobile Personal Computers has been experienced. Their market penetration is continuously increasing, mainly because they offer to their users the possibility to stay connected with their near ones and with the world whenever and(More)
