The Short Physical Performance Battery (SPPB) test was an assessment protocol used in Balansera to evaluate strength and balance. The SPPB score is based on timed and observational measures of standing balance, walking speed and the ability to rise from a chair (see Figure 1).
Balansera functions are intended to test functional leg strength and balance, providing an automatic feedback to the user. Sound and vibration signals are generated warning for abrupt movements, which are early indicators of a fall. Main inference module of Balansera is based on a rule-based system that is connected to a knowledge base repository. Experts such as physiotherapists, define limits and references of what an “optimal” movement looks-like (e.g. rising-up fast and sitting-down slowly), and Balansera compares reference information with data coming from phone embedded sensors.
