Validation of the Equidyn protocol for evaluation of dynamic balance in older adults through a smartphone application.

Background: Different tasks and proxy measurements have been employed to evaluate dynamic balance in older individuals. However, due to inherent limitations, results from most evaluations could hardly be taken as valid measurements of dynamic balance.

Research Question: Is the Equidyn smartphone application-based protocol valid and sensitive for assessment of dynamic balance in older adults?

Methods: Dynamic balance was evaluated in 52 physically active individuals, age range 60-80 years (M = 69.
