Publication number: 20240016440Abstract: Use of non-contact patient monitoring systems to detect, diagnose, monitor and/or adjust therapy for diseases or conditions that have motion-based symptoms, symptoms such as limb tremors, spasms, etc. that can be correlated to diseases or conditions such as Essential tremor, Parkinson's disease, restless leg syndrome, or a diabetic episode. Information garnered by the non-contact monitoring system, information such as location, frequency, severity, and duration of the motion, can be collected and analyzed so that a diagnosis can be made and/or a treatment plan developed and/or adjusted by the patient's caretaker. The non-contact monitoring can provide real-time feedback regarding effectiveness of therapies or treatments, such as, e.g., neurological stimulation.Type: ApplicationFiled: July 14, 2023Publication date: January 18, 2024Inventors: Thomas I.
