Characterization of the epley maneuver using a wearable inertial sensor

Self-administered interventions are an important clinical tool, but the ability to quantify the quality of these interventions is lacking from both the home and clinic. Here we use a wearable sensor and a custom analysis framework to evaluate the efficacy of video-guided and self-applied Epley maneuver. Performance of the maneuver is quantified by measurements of head orientation during and duration of static periods and average acceleration during dynamic periods. Preliminary results from five subjects demonstrate the utility of our approach and show that performance of the Epley maneuver can be quite variable, which emphasizes the need to understand how variability in the maneuver affects the quality of the intervention.
