Comparison of postoperative recovery of three groups of patients.
| Variables | Time since start of treatment | Total recovery time (day) | ||
|---|---|---|---|---|
| One month | Three months | Six months | ||
| US+NMES group (n = 80) | 21 | 59 | 77 | 60.31 ± 28.38 |
| NMES group (n = 80) | 10 | 41 | 60 | 72.15 ± 31.21 |
| US group (n = 80) | 16 | 46 | 66 | 72.26 ± 32.61 |
| T/χ 2 | 4.815 | 9.059 | 14.251 | 2.510/2.472 |
| P | 0.090 | 0.011 | 0.001 | 0.013∗/0.015# |
Data was expressed as mean ± SD or n. ∗P < 0.05, US+NMES group vs. NMES group; #P < 0.05, US+NMES group vs. US group. US: ultrasound; NMES: neuromuscular electrical stimulation; US+NMES: ultrasound combined with NMES.
