We anticipated that a 5-point improvement in the Falls Efficacy Scale International score would be sufficient to move typical patients in our nursing home from their current categorisation as high concern' into the "moderate concern category (Delbaere et al 2010), which we considered a clinically important change. Anticipating a standard deviation of 8.5, we calculated that 47 participants would provide 80% power to detect a difference of 5 points as significant at a two-sided, 5% significance level. To allow for some loss to follow-up, we aimed to recruit 50 participants Effect size was used to determine the magnitude of change and was calculated as the difference in the mean change in each group divided by the average of the standard deviations. Cohen's coefficient was used to assess the change. A change from 0-0.2 was considered very small, a change of 0.2-0.6 was considered small, a change of 0.6-1.2 was considered moderate, a change of 1.2-2 was considered large, and change of 2.0 was considered very large (Batterham and Hopkins 2006)
