Results of MWT determined (g).

Group	Before operation	1 d after operation	3 d after operation	7 d after operation	14 d after operation
Group C	16.3 ± 0.8	16.3 ± 0.8	16.3 ± 0.8	16.3 ± 0.8	16.3 ± 0.8
Group PS	16.1 ± 0.9	10.5 ± 0.2a	8.1 ± 0.7a	6.5 ± 0.6a	3.7 ± 0.4a
Group PR	16.2 ± 0.7	14.6 ± 0.3b	13.5 ± 0.4b	12 ± 0.7b	15.9 ± 0.8b

Results of MWT determined. The MWT at 1, 3, 7, and 14 d after operation in group PS is remarkably lower than that in group C (p < 0.05), while it is notably higher in group PR than that in group PS before operation and at 1, 3, 7, and 14 d after operation (p < 0.05). ^ap < 0.05 vs. group C; ^bp < 0.05 vs. group PS.
