Table 2 Enhancement in the view of cervical spines after arm traction and swimming position

From: Value of the swimming position and arm traction in visualizing the cervicothoracic junction over the standard lateral cervical X-ray

Lateral cervical X-rays Mean ± SD (mm) p value
Standard 12.60 ± 7.48  
Arm traction 21.73 ± 9.78 0.000a
Swimming position 21.20 ± 14.19 0.001b
p value 0.841c
