|---|---|---|---|---|---|
| Sham | SCI | Sham | SCI | ||
| Humerus | Ipsilateral | 210.6 ± 45.8 | 134.3 ± 26.9∗# | 34.5 ± 5.9 | 24.0 ± 4.1∗# |

| Radius | Ipsilateral | 116.8 ± 21.9 | 86.9 ± 32.4∗ | 19.6 ± 3.5 | 10.1 ± 3.5∗# |
| contralateral | 126.6 ± 26.2 | 133.0 ± 30.4 | 21.3 ± 4.2 | 16.7 ± 3.8 | |
| Vertebrae | 41.2 ± 9.2 | 32.7 ± 1.5 | 2.2 ± 0.7 | 2.0 ± 0.2 | |
Note: Data are expressed as means ± SD. ∗P < 0.05 between ipsilateral and contralateral sides in the SCI group; #P < 0.05 between the sham and SCI groups in the ipsilateral side (n = 4 and n = 8 in the humerus and radius in the sham and SCI groups; n = 4 in the vertebrae in the sham and SCI groups)
