Objectives: To determine whether padding the long spine board improves
patient comfort, affects cervical spine (c-spine) immobilization, or
increases sacral transcutaneous O-2 tension. Methods: A prospective ra
ndomized, controlled crossover study of healthy volunteers was conduct
ed over a two-week period. Participants included 30 volunteers with no
previous history of c-spine injury or disease. The subjects were rand
omized to either padded or unpadded long spine board immobilization wi
th serial measurements of discomfort (using a visual analog scale) and
transcutaneous tissue O-2 tension obtained at zero and 30 minutes. Me
asurements of ability to flex, extend, rotate, and laterally bend the
c-spine were made using a goniometer. The subjects then returned a min
imum of three days later to complete the opposite half of the study (p
added vs unpadded boards). Results: Subject discomfort was significant
ly reduced in the padded group compared with the unpadded group (p = 0
.024). There was no significant difference in flexion (p = 0.410), ext
ension (p = 0.231), rotation (p = 0.891), or lateral bending (p = 0.23
0) for the two groups. There was no significant difference in the actu
al drop in sacral transcutaneous O-2 tension from time zero to 30 minu
tes for the padded and the unpadded groups (mean drop = 14.8% +/- 17.5
% vs 12.2% +/- 16.8%, respectively; p = 0.906). Conclusion: Adding clo
sed-cell foam padding to a long spine board significantly improves com
fort without compromising c-spine immobilization. Sacral tissue oxygen
ation does not appear affected by such padding for healthy volunteers.
