Evaluating Mobility Interventions in the Real World


Author Organization(s):

Report Date:



Interventions for mobility disorders include many products and rehabilitation strategies, but there is little sound information about how different treatment options affect individuals movement in their daily lives. We propose todevelop new methods to assess the clinical effectiveness of these interventions using movement data from wearable sensors during everyday life. We hypothesize that frequently-repeated locomotion, such as walking the same pathsdaily near the home or in the workplace, are highly repeatable as in laboratory studies, but with greater ecological validity. We propose to compare the effects of different prostheses on these repeated movements using wearablesensor data such as foot movement and limb load. In the current reporting period, efforts at the University of Wisconsin focused on developing the sensor systems and data analysis methods. Efforts at subcontractor Walter Reed NMMC focused on protocol development and regulatory procedures, to begin study activities in year 2.
