Fig. 4 — a All the surgically treated sides: percentage of preoperative value (%) across a 14-day postoperative period. Physical activity (PA) dropped postoperatively from 100% to 45.3%, and regain of function was gradually observed on the surgically treated side through the increase in PA as a percentage of preoperative levels during the postoperative period. The greatest PA increase (mean PA, 45.3% vs. 56%; p < 0.05) was observed between days 1 and 2. The recovery plateau was identified on day 7 (64.7% ± 27.9%), which was the point at which no subsequent significant increase in activity was observed (from day 7 to day 14). b Disparity in recovery between the surgically treated arm and control arm movement activity during 2 weeks postoperatively. N.B. (nota bene): All the patients were right-handed except for 1 left-handed and 1 ambidextrous (22 right, 15 left, and 2 bilateral operations). Overall, greater regain of function, represented by greater activity, was observed in the control (non-surgically treated) side compared with the surgically treated side after week 1 (mean PA, 75.8% vs. 62.3%; p < 0.0005) and week 2 (mean PA, 91.6% vs. 77.4%; p < 0.005). The pattern was maintained throughout for postoperative days 1 to 3 (mean PA, 66.4% vs. 55.3%; p < 0.05), days 4 to 6 (mean PA, 83.7% vs. 68.5%; p < 0.005), days 7 to 9 (mean PA, 86.4% vs. 71.4%; p < 0.05), and days 10 to 12 (mean PA, 91.8% vs. 76.9%; p < 0.05). Intergroup comparison between the surgically treated and control sides during the 2 weeks demonstrated a statistically significant difference (p < 0.005), with a mean disparity of 13.9% ± 2.3%) between the sides.
