Effect of neck dissection type on average shoulder range of motion measurements in subgroup analysis (N=85)
| Measurement | No neck surgery (N=47) | Nerve sparing (N=24) | Nerve sacrificing (N=14) | p-value |
|---|---|---|---|---|
| R flexion (SD) | 140.30° (20.04) | 138.42° (22.26) | 122.71° (20.37) | .02* |
| L flexion | 142.91° (17.96) | 145.75° (17.22) | 139.07° (21.66) | .56 |
| R abduction | 138.51° (34.04) | 141.21° (32.75) | 102.57° (39.93) | .002* |
| L abduction | 146.83° (25.42) | 145.17° (30.12) | 127.21° (35.26) | .08 |
| R external rotation | 58.26° (12.67) | 56.83° (12.46) | 58.93° (18.40) | .88 |
| L external rotation | 57.66° (13.22) | 55.83° (12.75) | 54.21° (12.47) | .65 |
| R internal rotation | 70.96° (12.36) | 70.96° (9.12) | 64.93° (23.09) | .33 |
| L internal rotation | 70.89° (11.60) | 67.21° (11.96) | 72.21° (12.68) | .35 |
R = right; L = left; SD = standard deviation. Normal values of shoulder range of motion expressed in degrees are as follows: flexion 150°, abduction 150°, external rotation 90°, internal rotation 70° .37
