Plot of Change in DGI score versus time within the study period. The horizontal axis represents data acquisition time: 0 weeks is study entry (baseline), 2 weeks is end of lab training, and 6, 10, and 14 weeks are end of each 4-week home training period. The vertical axis represents the change in DGI relative to the baseline DGI value. Error bars are ± 1 SE; * indicates p < 0.05, ** indicates p < .005.
