Dr. Hondzinski's research interests involve the study of motor control and sensorimotor integration in tasks requiring whole body movements. She explores the control mechanisms during movements involving the entire body. Studies involve the effects of gaze direction, sensory alterations or neurodegeneration on movement of the body or body segments. The results of the experiments identify coordination strategies of "normal" subjects and contribute to the basic understanding of sensory use and movement variations effects for movement control. Such information may also be used to improve training regimes or expand rehabilitation strategies for individuals with deficits due to normal aging or pathology, such as vestibular loss, peripheral neuropathy, or Parkinson’s disease.
Dr. Hondzinski came to LSU after receiving her PhD in Exercise Science with specialization in Motor Control and Biomechanics and completing 2 years post-doctoral training in Motor Control. She was promoted to Professor in 2020 and is currently the Motor Behavior Area Coordinator for the Department of Kinesiology.
