Interests & Expertise
Kevin Keenan鈥檚 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.
