GROUP B
On POD1, 2 and 3, pain scores at rest were significantly lower for Group B (4.44 ± 0.58; 3.02 ± 0.71; 1.86 ± 0.67), C (3.32 ± 0.84; 1.82 ± 0.69; 0.96 ± 0.70), and D (3.28 ± 0.81; 1.74 ± 0.57; 0.80 ± 0.54) than for Group A (5.58 ± 0.61; 4.24 ± 0.70; 4.44 ± 0.58) (The comparison of VAS of pain at rest among the 4 groups on POD 1, 2, and 3. The one-way ANOVA was performed to detect the difference among the groups (*Consistent with pain scores at rest on POD1, 2 and 3, dynamic pain scores on POD1, 2, and 3 were significantly lower for Group B (6.60 ± 0.61; 5.02 ± 0.69; 3.96 ± 0.70), C (5.48 ± 0.89; 3.86 ± 0.73; 3.02 ± 0.65), and D (5.42 ± 0.84; 3.78 ± 0.62; 2.86 ± 0.50) than for Group A (7.70 ± 0.54; 6.24 ± 0.74; 4.52 ± 0.58) (The comparison of VAS of pain at walking among the 4 groups on POD 1, 2, and 3.
