Dr. Creath's research uses time series analysis methods to study perturbed postural control and gait. His research interests are to better understand: 1) the interaction between balance and mobility in older persons at risk for falling; and 2) hesitation in persons with Parkinson’s disease (PD) during step initiation. He hopes to use this knowledge to develop training methods that improve postural control and mobility in the elderly, and persons with PD.

Research/Clinical Keywords

postural control , data analysis, time series analysis, balance, gait
