Effect of radiation therapy on average range of motion measurements in subgroup analysis (N=85)
| Measurement | No XRT (N=11) | XRT (N=74) | p-value |
|---|---|---|---|
| R flexion (SD) | 130.00° (19.99) | 137.89° (21.61) | .26 |
| L flexion | 137.64° (22.43) | 143.89° (17.65) | .29 |
| R abduction | 131.64° (27.59) | 133.61° (38.30) | .87 |
| L abduction | 135.55° (32.58) | 144.26° (28.60) | .36 |
| R external rotation | 55.27° (14.16) | 58.36° (13.50) | .48 |
| L external rotation | 56.36° (11.94) | 56.61° (13.09) | .95 |
| R internal rotation | 66.73° (14.78) | 70.45° (13.84) | .41 |
| L internal rotation | 68.73° (7.04) | 70.27° (12.46) | .69 |
XRT = radiation therapy; 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
