Multi-input/output alarming system for patients with inattention caused by higher cortical function disorder

Background: To apply advanced methods of communication, sensing, and instrumentation technologies to make a system that can help patients suffering from hemispatial neglect caused by higher cortical function disorder.Method: By using several sensors and actuators, the objective was to construct a tailor-made system for each patient. The input part of the system consists of sensors, an interface and transmitters. The output part consists of a receiver, logical arithmetic, an output interface and actuators. The information from the input part is sent to the output part in a wireless manner allowing the mobility of the input and output parts.Results: The system and its functionality were realized. Voice alarming and neck muscle stimuli were applied to two patients. We could verify the applicability of the system to remind the patients to put on their wheelchair's brake and raise its footrest before attempting to stand for transferring to their beds.Conclusion: The designed and constructed multi-input/output system can be used effectively to alarm the patients.
