57 In another trial, similar effects were demonstrated when the exercise investigated was a specific motor and sensorimotor retraining program for the cervical spine combined with manual therapy.43 Other studies have investigated muscle strength and endurance training, vestibular exercises, and

exercises designed to challenge the postural system, with similar effects regardless Angiogenesis inhibitor of the exercise type.56 In a preliminary investigation, one randomised trial explored factors that may moderate the effects of a predominantly exercise-based intervention and found that participants with both cold and mechanical hyperalgesia did not respond to the intervention.43 However, these findings are limited by the small sample size and have not been replicated in a larger trial.58 So at present it is not clear which patients will respond to exercise approaches. From a clinical perspective, exercise and activity should be used in the treatment of both acute and chronic WAD. However, there is no evidence to indicate that one form

of exercise is superior to another and this is an area that requires further research. The generally small effect sizes with exercise suggest that either additional ABT 199 treatments will be needed, or that it is a sub-group of patients who show a better response. However, due to a lack of evidence, it is not clear which additional treatments should be included or how to clearly identify responders and non-responders. Thus, the recommendation to clinicians is that health outcomes should be monitored and treatment continued only when there is clear improvement. In patients whose condition Dichloromethane dehalogenase is not improving, the clinician will need to look for other factors that may be involved, such as psychological, environmental, or nociceptive processing factors amongst others. Various information and educational approaches including information booklets, websites and videos have been investigated for their effectiveness in improving outcomes following whiplash injury.59 In one trial,

an educational video of advice focusing on activation was more beneficial in decreasing WAD symptoms than no treatment at 24 weeks follow-up (outcome: no/mild symptoms vs moderate/severe symptoms), RR 0.79 (95% CI 0.59 to 1.06), but not at 52 weeks, RR 0.89 (95% CI 0.65 to 1.21).59 The results of other trials were equivocal and overall none of the interventions studied reduced the proportion of patients who developed chronic WAD. Currently, there appears to be wide variability in the nature of information and advice provided to a patient, suggesting that the best educational approaches as well as strategies for behaviour change and system change are yet to be established.60 Although patients understandably want advice on the prognosis and implications of their injury,61 it is not clear that advice per se will improve long-term outcomes or prevent chronic pain development.
