Efficacy of Postural and Neck Stabilization Exercises on Acute Whiplash-Associated Disorders: A Systematic Review Kara Drescher Sandra Hardy Jill MacLean Martine Schindler Katrin Scott  Outline „ „ „ „ „ „ „ „  Background Rationale Review Question Methods Results Discussion Conclusion Questions  Background  news.bbc.co.uk  Definition Whiplash is an acceleration-deceleration mechanism of energy transfer to the neck; it may result from rear-end or side-impact motor vehicle accidents (MVAs), but can also occur during diving or other traumatic events  Spitzer et al, 2005  Quebec Task Force (QTF) Classification of Whiplash-Associated Disorders (WAD) Grades „  Grade 0:  - No complaints about the neck - No physical signs  „  Grade 1:  - Neck complaint of pain, stiffness, or tenderness only - No physical signs  „  Grade 2:  - Neck complaint - Musculoskeletal signs  „  Grade 3:  - Neck complaint with neurological signs  „  Grade 4:  - Neck complaint - Fracture and/or dislocation Spitzer et al, 1995  Impact of WAD Soft tissue neck and back injuries account for approximately 60% of all bodily injury claims in MVAs „ WAD costs ICBC policyholders more than $600 million a year „ Chronic WAD cases are responsible for most of the disability costs „  Pathophysiology Potential damage to ligaments, muscles, nerves and/or boney structures „ Social, psychological and cultural factors influence perception of pain „  Spitzer et al, 1995; Rodriquez et al, 2004; Ferrari et al, 2005  Symptoms of WAD „ „ „ „ „ „ „  Neck pain Neck stiffness Headaches Shoulder pain Arm pain/numbness Paraesthesias Weakness  „ „ „ „ „ „  Dysphagia Visual disturbances Auditory symptoms Dizziness Cognitive disturbances Jaw pain  Spitzer et al, 1995; Rodriquez et al, 2004; Ferrari et al, 2005  Possible Treatments for WAD „ „ „ „ „ „ „  Exercise therapy Collars Prescribed rest Manipulation Mobilization Postural advice Traction  „ „ „ „ „ „ „  Electrotherapies Local heat/ice Ultrasound Massage Surgical intervention Steroid injection Pharmacology  Spitzer et al, 1995; Kay et al, 2006  Current Best Practice Guidelines „  The Netherlands: … Exercise … Education … Gradual  „  return to activity  British Columbia: … Exercise … Education … Manual  therapy … Gradual return to activity and participation  Scholten-Peeters, 2002; Leigh, 2004  Relevant Cochrane Reviews Kay et al, 2006: Exercises for mechanical neck disorders; and Verhagen et al, 2006: Conservative treatments for whiplash Both high quality reviews „ Found that studies of whiplash interventions were often of unacceptable quality, and there was a lack of consistent evidence „  Rationale Exercise is a widely used treatment „ Physiotherapy is an intervention that is expensive because it is labour-intensive „ Effectiveness of treatment needs to be evaluated to justify the expense „  Spitzer et al, 1995; Kay et al, 2006  Review Question In adults with acute whiplash-associated disorders, do neck stabilization and postural exercises have an effect on pain, range of motion and time off work?

with uncertain results „ Grade C: non-randomized and case control studies „  Sackett, 1989  Grading the Evidence According to Sackett Grade B evidence to support exercise in the treatment of pain in acute WAD „ Grade B evidence to suggest that exercise can decrease time off work, especially in the long term „ No supporting evidence that exercise will increase ROM „  Do Our Results Agree with the Verhagen and Kay Cochrane Reviews? „  „  „  No support for collar immobilization over exercise for decreasing pain or promoting early return to work Verhagen et al, 2006 found conflicting evidence regarding active versus passive treatment with respect to pain and return to work in the first six weeks Kay et al, 2006 found limited evidence supporting strengthening as a treatment for pain in neck disorders  Common Limitations of Included Studies „ „ „ „ „ „  Lack of quality: only one high quality study was included (Bunketorp et al, 2006) Lack of blinding of both subjects and outcome assessors Frequent rate of uncontrolled co-interventions High drop-out rates Lack of compliance Lack of description of the exercises  Limitations of Our Review Narrow focus which resulted in exclusion of studies with cointerventions „ Only systematic reviews from the Cochrane Database of Systematic Reviews were evaluated „  Practical and Clinical Implications „  Exercise is likely of value in the treatment of WAD „  „  Collars should be used sparingly in the treatment of WAD  Although the initial cost of active exercise intervention is high, the overall cost is less when taking into account time off work, reduced productivity and cost of other interventions  Future Questions Which specific exercise interventions are most beneficial in the treatment of WAD? „ What is the optimal frequency, intensity and duration for the different exercises? „  Conclusion Although the literature supports the use of active interventions in the treatment of acute whiplash-associated disorders, further research is needed to determine which exercises are most effective and at what frequency, intensity and duration should be prescribed  Acknowledgements Tyler Dumont „ Charlotte
