CON- attentional control group

p values represent the results of ANCOVA testing with baseline values as the covariate and the dependent variable being post intervention or the primary comparison of 1 year post fracture. The effect sizes are reported for the primary comparison of baseline to one year post fracture.

^*Indicates p=.04 for baseline differences between groups in mPPT scores; all other baseline comparisons were not statistically different.
