There is a growing interest in using perturbation-based balance training (PBT) to reduce falls. PBT is a skill training intervention that aims to improve reactive balance control in response to destabilizing perturbations in a safe and controlled environment. The concepts of the different falls-related self-efficacy (falls efficacy) constructs must be clarified. Having better clarity allows appropriate measures to be selected to elucidate the impact of PBT on the perceived ability to deal with falls.
