The requirement of agile adaptation to varying resource constraints in mobile systems motivates the use of a service-oriented architecture (SOA), which can support the composition of two or more services to form a complex service. In this paper, we propose SOA-based middleware to support QoS control of mobile applications and to configure an(More)
The need for fast treatment of patients in critical conditions motivates the use of mobile devices to provide prompt and consistent communication between hospitals and physicians. We propose a framework that supports ubiquitous access to medical systems using personalized mobile services and integrated medical systems. The proposed service-oriented medical(More)
BACKGROUND AND PURPOSE Information technology and mobile devices may be beneficial and useful in many aspects of stroke management, including recognition of stroke, transport and triage of patients, emergent stroke evaluation at the hospital, and rehabilitation. In this review, we address the contributions of information technology and mobile health to(More)
PURPOSE The benefits of thrombolytic treatment are time-dependent. We developed a smartphone application that aids stroke patient self-screening and hospital selection, and may also decrease hospital arrival time. MATERIALS AND METHODS The application was developed for iPhone and Android smartphones. Map data for the application were adopted from the open(More)
BACKGROUND The pronator drift test is widely used to detect mild arm weakness. We developed an application that runs on a handheld device to objectify the pronator drift test and investigated its feasibility in stroke patients. METHODS The iPronator application, which uses the built-in accelerometer in handheld devices, was developed. We enrolled acute(More)
Collective management of patient records enhances the ability to identify disease and supporting treatment decisions. We propose a Web-based system for the collective management of medical information for stroke patients. Our system collects data about acute stroke patients, allows physicians to collaborate over the Internet, simplifies physician reporting,(More)
Mobile medical systems utilize portable devices and wireless communication to access patients' clinical information for instant diagnosis. Our platform-based mobile diagnosis system monitors the context of service providers in medical organizations and of service consumers using mobile devices, while supporting medical information standards for the seamless(More)
Rapid evaluation and treatment of time-dependent diseases such as acute stroke need fast and consistent communication between medical service providers. Our framework accepts data from hospital systems and medical evaluations, and composes it into new forms to suit different recipients and mobile devices. We have implemented a prototype application for(More)
