CONCLUSIONS There was a consistent positive association among studies that have examined the association between MVC-related neck injury and future NP .
OBJECTIVE To summarize the literature that has examined the association between a motor vehicle collision ( MVC ) related neck injury and future neck pain ( NP )  in comparison with the population that has not been exposed to neck injury from an MVC .
LITERATURE SURVEY Neck injury result ing from an MVC is associated with a high rate of chronicity .
Prognosis studies indicate 50 % of injured people continue to experience NP a year after the collision .
This is difficult to interpret due to the high prevalence of NP in the general population .
The association between a lifetime history of a neck injury in a motor vehicle collision and future neck pain: a population-based cohort study
The objective of this population -based cohort study was to investigate the association between a lifetime history of neck injury from a motor vehicle collision and the development of troublesome neck pain . The current evidence suggests that individuals with a history of neck injury in a traffic collision are more likely to experience future neck pain . However , these results may suffer from residual confounding . Therefore , there is a need to test this association in a large population -based cohort with adequate control of known confounders . We formed a cohort of 919 r and omly sample d Saskatchewan adults with no or mild neck pain in September 1995 . At baseline , participants were asked if they ever injured their neck in a motor vehicle collision . Six and twelve months later , we asked about the presence of troublesome neck pain  ( grade II – IV ) on the chronic pain grade question naire . Multivariable Cox regression was used to estimate the association between a lifetime history of neck injury in a motor vehicle collision and the onset of troublesome neck pain while controlling for known confounders . The follow-up rate was 73.5 % ( 676/919 ) at 6 months and 63.1 % ( 580/919 ) at 1 year . We found a positive association between a history of neck injury in a motor vehicle collision and the onset of troublesome neck pain after controlling for bodily pain and body mass index ( adjusted HRR = 2.14 ; 95 % CI 1.12–4.10 ) . Our analysis suggests that a history of neck injury in a motor vehicle collision is a risk factor for developing future troublesome neck pain . The consequences of a neck injury in a motor vehicle collision can have long lasting effects and predispose individuals to experience recurrent episodes of neck pain
