nQ Medical shares new research with UTHealth Houston and Cleveland Clinic on digital biomarkers.
CAMBRIDGE, Mass., Aug. 9, 2022 /PRNewswire-PRWeb/ -- People's keystroke patterns generated from their daily interaction with computers and smartphones can reveal important information about their cognitive state, according to new research published by nQ Medical, UTHealth Houston, and Cleveland Clinic.
nQ Medical, a company transforming neurology care with digital biomarkers and virtual first offerings to manage neurodegenerative diseases, announced today that Brain Communications has published a new paper focused around their novel work on the development of digital biomarkers for subdomain analysis of the cognitive function (DOI:fcac194 https://doi.org/10.1093/braincomms/fcac194), done in collaboration with UTHealth Houston School of Biomedical Informatics , and the Cleveland Clinic Lou Ruvo Center for Brain Health.
nQ introduces a novel approach that leverages a data source collected remotely by passively monitoring users' daily finger interactions with their personal devices, facilitating longitudinal patient assessment in the real-world scenario, and with high patient compliance. "In this work, we used machine learning algorithms to estimate cognitive performance through the analysis of keystroke dynamic patterns that were extracted from mechanical and touchscreen keyboard use in a dataset of healthy controls and cognitively impaired subjects. These algorithms are trained and evaluated using a novel framework that integrates items from multiple neuropsychological and clinical scales into cognitive subdomains to generate a more holistic representation of multifaceted clinical signs," explained Luca Giancardo, PhD, Assistant Professor and one of the principal investigators with the Center for Precision Health at UTHealth Houston School of Biomedical Informatics.
"We believe that digital biomarkers are the foundation for measurement-based neurological health care, for which there is a significant unmet patient need. In this study we showed that the way a person types on a mechanical keyboard or mobile phone correlated with how they perform on standardized tests. This is an exciting finding as we move toward new tools that measure cognitive function and brain health that are quantitative, reproducible, continuous, and objective," said study co-author, Aaron Ritter, MD, Neuropsychiatrist at the Cleveland Clinic Lou Ruvo Center for Brain Health, in Las Vegas.
Smartphone users touch and interact with their devices many times over many hours each day, engaging in complex actions and gestures —what nQ refers to as keystroke and touchscreen dynamics. "The brain, finger, device connection is controlled by complex cognitive and fine motor processes. At nQ we work on the development of pattern recognition techniques that translate our daily typing patterns into quantitative metrics about our psychomotor health. nQ tracks 'how' you use your device not 'what' you are doing on your device. We can extract valuable clinical information without invading the user's privacy. We do not need to view user messages, app and website use, nor geolocation or media," explains Teresa Arroyo Gallego, PhD, Chief Data Scientist at nQ Medical.
"The traditional measures of neurological health are infrequent, subjective, and expensive clinician-administered tests. They have relatively low inter-rater reliability, and don't assess patients in real world settings. Cognitive and motor function vary widely from hour to hour, day to day, and are subject to a range of environmental factors. Real-time, continuous, objective measurements in the home and community are key for enabling a new outpatient care model for neurology patients," added Dr. Arroyo Gallego.
In the study, participants underwent a series of pre-defined typing tasks designed to emulate daily interactions with computers and smartphones. In addition, they underwent a comprehensive neurocognitive assessment involving 16 neuropsychiatric tests and PET Scan. Using machine learning, the team was able to optimize a collection of typing-based metrics against specific subdomains of cognitive performance. In particular, results exhibited stronger performance in the quantification of executive function, verbal and non-verbal memory and language skills subdomains.
The team looks at these results as a step forward towards our goal of turning real-world user-device interaction into a powerful everyday monitoring tool for continuous, objective and precise characterization of people's psychomotor health.
