Trisha Kesar

Trisha Kesar, PhD, PT (Lab Director)


Email:  

Dr. Kesar earned her physical therapy degree from Post Graduate Institute of Medical Education and Research (PGIMER) in Chandigarh, India. In 2009, she earned a PhD degree from the Biomechanics and Movement Science Graduate Program at the University of Delaware. After completion of post-doctoral training at Delaware and at the University of Maryland at Baltimore, Dr. Kesar joined the Division of Physical Therapy as an Assistant Professor in May 2012. Dr. Kesar is the Director of the Motions Lab at Emory.


Research Interests

Kesar biomechanics imageDr. Kesar’s research goal is to develop novel gait rehabilitation interventions and strategies that are based on an in-depth understanding of the neuroplasticity, biomechanical, and motor learning mechanisms underlying gait and gait training. Ongoing projects in Dr. Kesar’s lab are investigating the time course of evolution of changes in gait biomechanics, walking function, and corticospinal excitability during paradigms that mimic clinical post-stroke gait retraining. Some of the tools and techniques that Dr. Kesar employs in her research include 3-dimensional kinematic and kinetic analysis of human motion, electromyography, functional electrical stimulation, and transcranial magnetic stimulation. Dr. Kesar’s publications span the areas of muscle physiology, functional electrical stimulation, post-stroke gait biomechanics, neurophysiology, and stroke gait rehabilitation.

Marie A. Johanson

Marie A. Johanson, PhD, PT, OCS


Email:  

Dr. Marie Johanson is an Associate Professor and Associate Director in the Division of Physical Therapy, Department of Rehabilitation Medicine. She completed her professional training in physical therapy at Emory University in 1982 and earned a post-professional master's degree in Orthopedic Physical Therapy (1991) and a PhD in Higher Education (2003) from Georgia State University. She has been a certified orthopedic specialist since 1994. Dr. Johanson's primary teaching responsibilities within the DPT program are Course Director for Health Promotion, Wellness and Prevention: Individual level (DPT 700), Course Director for Evidenced Based Practice (DPT 765), Instructor for Musculoskeletal Rehabilitation (DPT 800), and Course Coordinator for Clinical Research I and II (DPT 915 and DPT 925). Dr. Johanson also serves on the Orthopaedic Specialty Council , American Board of Physical Therapy Specialties, and as an Editorial Board Member for the Journal of Physical Therapy Education.


Johanson biomechanics imageResearch Interests

Dr. Johanson's research focuses on the biomechanics of walking among individuals with lower extremity impairments, before and after specific interventions, with particular emphasis on the foot and ankle. She is currently investigating the effects of subtalar joint position during gastrocnemius stretching on midfoot versus ankle/rearfoot biomechanics (both during stretching and when walking) among patients with lower extremity overuse injuries. Her ultimate goal is to develop or refine rehabilitative interventions that optimize patients’ gait patterns, resulting in improved function.

 

 


Benjamin M. Rogozinski

Benjamin M. Rogozinski, DPT


Email:

Dr. Rogozinski is an Assistant Professor in the Division of Physical Therapy, Department of Rehabilitation Medicine. His background is in biomechanics as it relates to normal and pathological gait in the pediatric population. Following graduation from the University of South Carolina in 2004 he accepted a position in the motion analysis laboratory at the Shriners Hospitals for Children in Greenville, South Carolina. There he was part of collaborative team that utilized clinical gait analysis to develop surgical treatment plans for children with neuromuscular disorders. In addition to the clinical testing and gait interpretation occurring in the lab, he was actively involved in the education of gait analysis interpretation at a regional and national level. Dr. Rogozinski’s primary teaching responsibilities within the DPT program are Course Director for Kinesiology and Biomechanics (DPT 715), Pediatric Rehabilitation (DPT 815) and Strength and Conditioning (DPT 982).


Rogozinski biomechanics imageResearch Interests

With a global research interest in the use of quantitative gait analysis in the development and assessment of intervention strategies to improve function and quality of movement of children with neuromuscular disorders, Dr. Rogozinski has published papers investigating the effects of surgery and orthotics on gait kinematics and kinetics in children with cerebral palsy. Dr. Rogozinski has recently established collaboration with Children’s Hospital of Atlanta’s Department of Orthopedics and will begin routine clinical gait analysis in 2013.

 


Manning J Sabatier

Manning J Sabatier, PhD


Email:  

Manning J Sabatier received his B.S. (1999) and M.S. (2001) degrees in Kinesiology from the University of Louisiana at Lafayette, and Louisiana State University, respectively. In 2005 he completed his Ph.D. degree in Exercise Physiology from The University of Georgia in Athens, Georgia. From 2005 to 2007 he was a postdoctoral fellow with the Fellowships in Research and Science Teaching (FIRST) program in the Emory University School of Medicine, under the research guidance of Author English. His research focused on use of enzyme treatments and exercise to facilitate recovery from peripheral nerve injuries. He was an Assistant Professor of Health and Fitness Management at Clayton State University from 2008 to 2012. He began his current position (Assistant Professor of Rehabilitation Medicine, Emory School of Medicine) in Aug 2012. Dr. Sabatier teaches the Systems Physiology course for physical therapy graduate students and conducts research. He has published studies on the physiology of exercise in aging, obesity, spinal cord injury, and peripheral nerve injury and has used methodologies in cardiovascular physiology, muscle physiology and neuroscience to conduct investigations.


Research Interests

Dr. Sabatier’s current research focuses on the effect of muscle injury and pain on spinal synaptic transmission and the control of movement. Patients with neurological deficits present with detrained skeletal muscle that is more susceptible to injury related to normal use, complicating rehabilitation for these individuals. Dr. Sabatier is currently using biomechanical assays in conjunction with a model of exercise-induced muscle injury and delayed onset muscle soreness to investigate how the milieu of afferent feedback from muscle interacts to affect locomotion. He specifically evaluates EMG activity patterns of lower extremity muscles, and sagittal plane kinematics of the lower extremity joints, during slope walking. For other details see Dr. Sabatier faculty web page.
