a Mean total daytime (light phase) and nighttime (dark phase) activity counts for each 12-h time period over a 7-day recording period. *Significantly different from every other day data point (p < 0.02). ^#Different from time 0 day (p < 0.04). ⁺Same as week 1 day (p > 0.05). b Mean number of daytime (light phase) rest periods and nighttime (dark phase) activity bouts for each 12-h cycle over a 7-day recording period. *p < 0.04, ^# < 0.05. c Mean total duration of daytime (light phase) rest periods and nighttime (dark phase) activity bouts over each 12-h cycle over a 7-day recording period. d Mean total activity count each hour over a 24-h cycle and 7-day recording period—one-way within-subjects analysis of variance with multiple dependent measures (time of day and postoperative time). *Different between preoperative and 20 weeks postoperatively within subject
