Postural imbalance can be adopted for the early detection of age-related diseases or monitoring the course of the disease treatment; especially in monitoring, frequent balance measurement is crucial. This is mainly done through regular in-person examinations by a physician currently. Feedback in between examinations is often missing.
This paper proposes mBalance, a mobile application that uses the Romberg test to detect postural imbalance. mBalance provides a camera-based, low-cost approach to measure imbalance frequently at home using mobile devices.
Imbalance detection accuracy and usability was evaluated in two separate studies with 31 and 30 participants, respectively.
mBalance correctly detected imbalance with a sensitivity of 80% and a specificity of 87%. The study found good usability with no significant problems.
Overall, this study solves the problem of postural imbalance detection by digitizing a validated balance test into an easy-to-use mobile application.
