Area(s) of Specialization:
walking, gait speed, personal monitoring, step counting, ambulation
I am a walking behavior researcher and am a recognized world leader in objective physical activity assessment and promotion, specifically focused on pedometer or accelerometer-determined ambulatory activity captured as steps/day across the lifespan. I am a trained program evaluator and adult educator focused on practical applications in objective monitoring measurement and intervention. I have also published on clinical vs. free-living gait analysis, including interpretation of cadence as a simple indicator of ambulatory patterns. I have also published work documenting the relationship between time spent in sedentary behavior and relatively low ambulatory activity, measured as steps/day.
I have led the field in elevating the acceptance of step counting using a variety of body worn motion sensors for researchers, practitioners, and lay audiences. I have set benchmark values for interpretation, standardized measurement protocols, and developed program templates centered around step counting. I have recently pushed the field into using free-living indices of cadence to further describe ambulatory behavior in terms of “natural effort.” I have established a step-defined index for sedentary behavior that has been applied by many researchers and practitioners.
