Inertial measurement units (IMUs) are self-contained devices that measure kinematic information without emitting signals or requiring external references. Advances in MEMs technology combined with improved sensor fusion and estimation techniques have made IMUs the preferred sensing modality for a growing number of biomechanical applications. IMUs attached to the feet can provide measures of stride distances and variabilities during walking, with accuracy comparable to more expensive and less portable systems such as optical-based motion capture system and gait mats. We have proven that adding an additional sensor to the subject's torso provides enough information to generate high-quality reconstructions of more complex events such as losses-of-balance and falls. This talk will discuss a number of medical applications that utilize IMUs, including gait assessment, long-term monitoring, event reconstruction, and biofeedback.
