Determining the Optimal Dose of Reactive Balance Training After Stroke

A research physiotherapist will oversee reactive balance training (RBT) to ensure consistent RBT delivery across participants. Training strategies will be individualized to each participant, based on their balance impairments and rehabilitation goals. The RBT program includes multi-directional 'internal' and 'external' balance perturbations. Internal perturbations are achieved by asking the participant to complete tasks that challenge balance control, such that they lose balance when attempting to perform the task (e.g., kicking a soccer ball). External perturbation are delivered manually using a push or pull from the physiotherapist. As participants improve their reactive balance control, difficulty will be increased by shifting task requirements along a continuum from stable to mobile, and from predictable to unpredictable, and by increasing perturbation magnitude or imposing sensory or environmental challenges.
