Pearson correlation coefficients (p value) for mass and height with cervical spine movement for each extrication technique
| Cervical spine movement (°) | ||||||
|---|---|---|---|---|---|---|
| Control (no collar) | Collar (support) | LSB (in-line) | LSB (passenger) | LSB (driver) | SEJ (driver) | |
| Mass | r=0.38 (p=0.15) | r=0.48 (p=0.06) | r=0.48 (p=0.06) | r=0.61 (p=0.01)* | r=0.22 (p=0.43) | r=0.39 (p=0.13) |
| Height | r=0.56 (p=0.03)* | r=0.29 (p=0.28) | r=0.43 (p=0.10) | r=0.46 (p=0.08) | r=0.39 (p=0.14) | r=0.65 (p=0.007)* |
*p<0.05.
LSB, long spinal board; SEJ, short extrication jacket.
