Neck Injury in a Motor Vehicle Collision and Future Neck Pain

Neck Injury in a Motor Vehicle Collision and Future Neck Pain

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.

A cohort of 919 randomly sampled Saskatchewan adults with no or mild neck pain in September 1995 were formed. 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 questionnaire. 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.

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 was found. The 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.

A study published in the British Journal of Orthopaedic Medicine (1999)22(1):22-25 reported that chiropractic is the only proven effective treatment in chronic cases of whiplash injury. The study was prompted by a previous article in the journal Injury which demonstrated that chiropractic treatment had benefited 26 out of 28 patients suffering from chronic whiplash syndrome.

Manual therapy and exercise for neck pain: a systematic review

Manual therapy and exercise for neck pain: a systematic review.

Miller J, Gross A, D'Sylva J, Burnie SJ, Goldsmith CH, Graham N, Haines T, Brønfort G, Hoving JL

Manual therapy is often used with exercise to treat neck pain. This cervical overview group systematic review update assesses if manual therapy, including manipulation or mobilisation, combined with exercise improves pain, function/disability, quality of life, global perceived effect, and patient satisfaction for adults with neck pain with or without cervicogenic headache or radiculopathy. Computerized searches were performed to July 2009. Two or more authors independently selected studies, abstracted data, and assessed methodological quality. Pooled relative risk (pRR) and standardized mean differences (pSMD) were calculated. Of 17 randomized controlled trials included, 29% had a low risk of bias. Low quality evidence suggests clinically important long-term improvements in pain (pSMD-0.87(95% CI: -1.69, -0.06)), function/disability, and global perceived effect when manual therapy and exercise are compared to no treatment. High quality evidence suggestsgreater short-term pain relief [pSMD-0.50(95% CI: -0.76, -0.24)] than exercise alone, but no long-term differences across multiple outcomes for (sub)acute/chronic neck pain with or without cervicogenic headache. Moderate quality evidence supports this treatment combination for pain reduction and improved quality of life over manual therapy alone for chronic neck pain; and suggests greater short-term pain reduction when compared to traditional care for acute whiplash. Evidence regarding radiculopathy was sparse. Specific research recommendations are made.
