Wearable stroke rehabilitation device gives patients the upper hand

University of Massachusetts Amherst
Peer-Reviewed Publication

A team led by University of Massachusetts Amherst researchers has developed a wearable wrist device powered by a machine-learning algorithm that can continually track changes in arm movement impairment caused by strokes. Monitoring changes throughout the entire rehabilitation process will allow clinicians to make real-time adjustments to therapy programs for tailored interventions and personalized care instead of the one-size-fits-all current standard.

Your voice may reveal how fast and how well you’re aging – new research

Trinity College Dublin
Peer-Reviewed Publication

A large study shows that machine-learning clocks based on speech can estimate chronological age and may also offer a window into brain aging, biological aging, cognitive health, cumulative burden, and dementia.

The new study, just published in leading international journal Science Advances, outlines that researchers have developed a “speech clock” that can estimate a person’s chronological age from hundreds of acoustic and linguistic characteristics of their speech. The difference between a person’s actual age and their speech-predicted age (called the speech age gap) was also associated with multiple independent markers of biological aging, brain health, cognition, social adversity, and dementia.
