Change in Balance Performance from Baseline to Post-Intervention Timepoint |
Six balance tasks, adapted from the Berg Balance Scale, were administered with simultaneous functional near infrared spectroscopy (see secondary outcomes). Each balance task was evaluated using Functional Independence Measure (FIM) scoring, ranging from 0 (dependent, unable to do) to 7 (independent, able to do without help). A composite score was generated by averaging FIM scores from each balance task. Change in balance was quantified as the difference in the post-intervention balance composite score and the baseline balance composite score. |
Baseline was ~ 2 weeks before the start of group yoga; Post-Intervention was after the last group yoga class, which was 12-13 weeks after baseline assessment. |

Change in Executive Functioning from Baseline to Post-Intervention Timepoint |
Executive function was assessed with a self-report measure, the Behavior Rating Inventory of Executive Function - Adult Version. The BRIEF-A includes nine clinical scales: inhibit, self-monitor, plan/organize, shift, initiate, task monitor, emotional control, working memory and organization of materials. Items are self-rated using a three-point frequency scale (1 = never; 2=sometimes; 3=often). These items contribute to two broad indexes, behavioral regulation and metacognition, which are combined for a summary score. Raw scores are transformed into a T-score. Higher T scores reflect more reported problems and T scores at or above 65 are considered clinically significant. |
Baseline was ~ 2 weeks before the start of group yoga; Post-Intervention was after the last group yoga class, which was 12-13 weeks after baseline assessment. |
