In this case-control study technical and medical circumstances of CSD Injury after rear-end car crashes are compared between patients showing different time spans to recover.
Drivers with CSD injuries are divided to patients showing symptoms for more than 6 weeks and up to 6 months (80 controls) and chronic patients suffering for more than 6 months (22 cases). Statistical Analysis is performed by applying Chi-Square and Mann-Whitney U-Test, documented are Odds Ratios with 95% Confidence-Intervals and p-values.
In general chronic CSD patients had been involved in biomechanically more complex Rear End accident situations, but significant higher frequencies are found for the factors low head-restraint positioning and psychological factors associated with the time to recover.
