Aim II
One of the goals of Aim II is to generate preliminary estimates of the sensitivity of balance measures (Mini-BESTest and ISAW) due to the Tele-ABC program. These estimates ultimately will be used to inform power and sample size computations for a larger clinical trial. We did examine effect sizes detectable by intervention at the planned sample size and related these to effect sizes observed in other similar interventions. In our pilot study, we observed improved dual-task gait speed using the same, wearable mobility sensors after an in-person balance exercise intervention [
