Biography

Narayanan Krishnamurthi is an assistant professor in the College of Nursing and Health Innovation at Arizona State University. He received his Ph.D. from Indian Institute of Technology, Madras, India in the field of biomedical data analyses. Later, he did my postdoctoral fellowship in a unique program, Integrated Rehabilitation Engineering Program (IREP), at Harvard Medical School and Boston University, MA. He joined the College of Nursing and Health Innovation as an assistant professor in 2013.

Professor Krishnamurthi's main research interests include developing therapeutic interventions to preserve function (mobility and quality of life) in aging population, improve/restore function with neurological disorders such as Parkinson's disease. He is also interested in utilizing wearable sensors towards continuous evaluation of gait. His interventions are mainly aimed towards taking advantage of neural plasticity in paradigms that can be effectively utilized in the clinic and/or home environment to facilitate functional recovery. Also, he is interested in quantitative characterization of gait and posture control impairments and cardiovascular and cardiorespiratory dysfunctions.

Research Interests

Dr. Krishnamurthi’s main research interests include developing therapeutic interventions to preserve function (mobility and quality of life) in aging population and improve/restore function with neurological disorders such as Parkinson’s disease and spinal cord injury. His interventions are mainly aimed towards taking advantage of neural plasticity in paradigms that can be effectively utilized in the clinic and/or home environment to facilitate functional recovery. He is also interested in quantitative characterization of gait and posture control impairments and cardiovascular and cardiorespiratory dysfunctions.

Dr. Krishnamurthi has received research grants from National Institutes of Health, Paralyzed Veterans of America Research Foundation, and Arizona State University-Mayo Clinic Seed Grant Program to support his investigations on the effects of polestriding and novel dance training to improve quality of life in Parkinson’s disease and electrical stimulation of legs muscles to alleviate orthostatic hypotension in spinal cord injury. He is also currently investigating the effects of certain deep brain stimulation parameters and a novel real-time feedback paradigm to improve balance and gait in Parkinson’s disease.

ASU-Mayo Seed Grant Program; $50,000; Role: PI; 01/01/18 – 12/31/18

To investigate whether participating in an exercise program that uses the feedback on a regular basis can improve gait patterns and posture during every day activities such as overground walking.

 

Long-term continuous monitoring to characterize the effects of deep brain stimulation on gait and balance dysfunction in people with Parkinson’s disease

Project HoneyBee, Center for Sustainable Health, Arizona State University

09/01/15 – 08/31/16; $26,921; Role: PI

The proposed will investigate the effects of subthalamic or globus pallidus internus deep brain stimulation (DBS) on gait in people with PD by obtaining quantitative gait variables continuously for 7 days in their home environment at pre- and 6 months post-DBS.  The continuous gait will be obtained using wearable sensors. This study may help to understand whether there are any improvements in gait due to DBS during activities of daily living.
