The normality of the PROs will be assessed by testing of skew and kurtosis. Nonparametric statistical tests will be used to evaluate PROs that are not normally distributed. Student's paired T-test will be used to estimate the effect of the intervention on primary and secondary outcomes. Additionally, the Wilcoxon rank sum test will be used to compare the degree of change in these scores between patients randomized to the intervention group who did and did not comply with REST. The magnitude and directions of the relationships between change in mean steps per day during the training interval (calculated as mean from week 10 minus mean from baseline) and changes in PRO scores will be assessed with Pearson correlation coefficients. Given the pilot nature of this work, adjustments will not be made for multiple comparisons.
