Gait analysis accuracy: Android app comparable to standard accelerometer methodology

Smartphones are becoming more ubiquitous and many have a built in tri-axial accelerometer, a sensor that measures change in speed in multiple directions. These smartphone accelerometers can be used to assess gait patterns, or walking patterns, an important evaluation in many neurologic or musculoskeletal disorders. However, the reliability and validity of using smartphones to assess gait patterns is not yet fully established evaluated. In Japan, a team of registered physical therapists and other physicians performed a study to do just that. iMedicalapps
