Dr. Keenan’s work is dedicated to understanding the interplay between motor function, physical activity, and health. Experimental procedures used in the laboratory include high-density surface EMG arrays (up to 256 EMG recordings), long-term (>6 hrs) EMG recordings, indwelling EMG recordings, force sensors, motion capture, and computational modeling.
Current collaborative projects being pursued in the lab include: the role of physical activity on motor function in older adults; assessment of muscle coordination during finger pressing tasks in young and older adults; the role of EMG biofeedback to improve chronic neck pain; the change in neuromuscular control in stroke survivors, and the noninvasive assessment of neuromuscular properties using high-density EMG arrays.
