Smart phone as a tool for measuring anticipatory postural adjustments in healthy subjects, a step toward more personalized healthcare

We present a study on using a smart phone as a tool to evaluate anticipatory postural adjustments (APA) before the beginning of normal gait in healthy subjects. The results show a significantly lower amplitude of anticipatory postural adjustments in the mediolateral axis (ML) when subjects used the non-dominant leg for the first step compared with the amplitude when using the dominant leg. The use of smart phones as a tool for measuring APA enables more personalized and active healthcare for the population without the necessity of their buying or carrying other devices.
