Neck collar, "act-as-usual" or active mobilization for whiplash injury? A randomized parallel-group trial

The quality of reporting in randomized controlled trials investigating exercise for individuals with whiplash-associated disorders; a systematic review

BACKGROUND

Whiplash-associated disorders are a common sequela of road traffic accidents. Exercise therapy is considered an effective intervention, and it is recommended for the management of such condition. However, the application of research findings to everyday clinical practice is dependent on sufficient details being reported.

OBJECTIVES

To explore the quality of reporting in studies investigating the effectiveness of exercise for whiplash-associated disorders.

METHODS

A literature search was conducted to identify studies testing the effectiveness of exercise for whiplash-associated disorders. Two reporting checklists were used to evaluate reporting completeness. The median positive scores for each study and overall percentage of positive scores for each item were calculated. Percentage agreement and the Cohen's Kappa coefficient were calculated.

RESULTS

Twenty-one studies were included. According to the Template for Intervention Description and Replication checklist, items were reported appropriately with a median of 29% (range 0-95%, IQR 40.5). The median number of adequately reported items per study was 5 (range 1-10, IQR 3). For the Consensus on Exercise Reporting Template checklist, items were reported appropriately with a median of 29% (range 0-57%, IQR 29). The median number of adequately reported items per study was 4 (range 0-16, IQR 8). Percentage agreement ranged from 57% to 100% while Cohen's Kappa from -0.17 to 1.00.

CONCLUSIONS

The study reveals significant gaps in the quality of reporting in studies investigating exercise for whiplash-associated disorders as both checklists showed a median reporting adequacy of only 29%. Overall, the inter-rater agreement for both checklists was acceptable.

The Role of Orthoses in Chronic Axial Spinal Conditions

PURPOSE OF REVIEW

Bracing represents a prevalent conservative, non-surgical approach used in the management of chronic spinal conditions such as spondylosis, degenerative disc disease, and spondylolisthesis. A wide variety of orthoses are available to aid in addressing cervical, thoracic, lumbar, thoracic, and SI joint pain. In this review, we aim to comprehensively examine brace types with their current applications and implications of usage.

RECENT FINDINGS

There are multiple cervical bracing options, such as soft and rigid collars, to assist in managing acute trauma and chronic degenerative conditions. The review highlights the nuanced decision-making process between hard and soft collars based on the severity of bone or ligamentous injury and neurological findings. Orthoses for low back pain are commonly used. The review highlights the challenges of chronic neck and lower back pain, emphasizing the importance of clinicians exploring all treatment strategies including braces which can improve function and reduce pain.

Effectiveness of Interventions on Work Outcomes After Road Traffic Crash-Related Musculoskeletal Injuries: A Systematic Review and Meta-analysis

BACKGROUND

Musculoskeletal injuries are common after road traffic crash (RTC) and can lead to poor work-related outcomes. This review evaluated the impact of interventions on work-related (e.g. sick leave), health, and functional outcomes in individuals with a RTC-related musculoskeletal injury, and explored what factors were associated with work-related outcomes.

METHODS

Searches of seven databases were conducted up until 9/03/2023. Eligible interventions included adults with RTC-related musculoskeletal injuries, a comparison group, and a work-related outcome, and were in English. Meta-analyses were conducted using RevMan and meta-regressions in Stata.

RESULTS

Studies (n = 27) were predominantly conducted in countries with third-party liability schemes (n = 26), by physiotherapists (n = 17), and in participants with whiplash injuries (94%). Pooled effects in favour of the intervention group were seen overall (SMD = - 0.14, 95% CI: - 0.29, 0.00), for time to return to work (- 17.84 days, 95% CI: - 24.94, - 10.74), likelihood of returning to full duties vs. partial duties (RR = 1.17, 95% CI: 1.01, 1.36), decreased pain intensity (- 6.17 units, 95% CI: - 11.96, - 0.39, 100-point scale), and neck disability (- 1.77 units, 95% CI: - 3.24, - 0.30, 50-point scale).

DISCUSSION

Interventions after RTC can reduce time to return to work and increase the likelihood of returning to normal duties, but the results for these outcomes were based on a small number of studies with low-quality evidence. Further research is needed to evaluate a broader range of interventions, musculoskeletal injury types, and to include better quality work-related outcomes.

Posttraumatic Stress Symptoms and Pain Sensitization After Whiplash Injury: A Longitudinal Cohort Study With Quantitative Sensory Testing

Posttraumatic stress symptoms (PTSS) are common after whiplash injury and are associated with poor recovery. The acute stress response may lead to pain sensitization and widespread pain, thereby compromising recovery. To our knowledge, no longitudinal study has assessed the associations between early PTSS and pain sensitization over time using quantitative sensory testing (QST). The aim of this study was to compare participants with different levels of PTSS, as measured by the impact of event scale (IES; subclinical 0–8, mild 9–25, and clinical ≥ 26) at baseline (<10-day post-injury) and at a follow-up of 1, 3, 6, and 12-month post-injury on pain sensitivity, neck mobility, pain distribution, and pain intensity. In total, 740 participants were recruited from emergency units or general practitioners with acute neck pain after a whiplash injury. The clinical PTSS group showed increased pain sensitivity on all QSTs at all time points compared to the subclinical PTSS group. Also, the clinical PTSS group showed significantly lower neck mobility at all time points except for a 3-month follow-up compared to the subclinical PTSS group. Moreover, the clinical PTSS group showed more widespread pain and self-reported headache and neck pain intensity at all time points compared to the subclinical PTSS group. This study emphasizes that participants with clinical levels of PTSS constitute a high-risk group that is sensitized to pain early after the injury. Hence, screening for PTSS within the 1st week after whiplash injury for those who experience high levels of pain intensity and distress may be an important clinical procedure in the assessment and treatment of whiplash-associated disorders (WAD).

Exercise therapy for whiplash-associated disorders: a systematic review and meta-analysis

OBJECTIVES

Acute as well as chronic pain syndromes are common after whiplash trauma and exercise therapy is proposed as one possible intervention strategy. The aim of the present systematic review was to evaluate the effect of exercise therapy in patients with Whiplash-Associated Disorders for the improvement of neck pain and neck disability, compared with other therapeutic interventions, placebo interventions, no treatment, or waiting list.

CONTENT

The review was registered in Prospero (CRD42017060356) and conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. A literature search in PubMed, Scopus and Cochrane from inception until January 13, 2020 was combined with a hand search to identify eligible randomized controlled studies. Abstract screening, full text assessment and risk of bias assessment (Cochrane RoB 2.0) were conducted by two independent reviewers.

SUMMARY

The search identified 4,103 articles. After removal of duplicates, screening of 2,921 abstracts and full text assessment of 100 articles, 27 articles that reported data for 2,127 patients were included. The included articles evaluated the effect of exercise therapy on neck pain, neck disability or other outcome measures and indicated some positive effects from exercise, but many studies lacked control groups not receiving active treatment. Studies on exercise that could be included in the random-effect meta-analysis showed significant short-term effects on neck pain and medium-term effects on neck disability.

OUTLOOK

Despite a large number of articles published in the area of exercise therapy and Whiplash-Associated Disorders, the current evidence base is weak. The results from the present review with meta-analysis suggests that exercise therapy may provide additional effect for improvement of neck pain and disability in patients with Whiplash-Associated Disorders.

Use of Soft Cervical Collar among Whiplash Patients in Two Italian Emergency Departments Is Associated with Persistence of Symptoms: A Propensity Score Matching Analysis

Purpose: Although the use of soft cervical collars in the emergency department (ED), for whiplash-associated disorders (WAD), is controversial, it is still widely adopted. The purpose of our study was to investigate the impact of the early use of soft cervical collars on the return to the ED, within three months of a road traffic collision. Methods: We conducted a retrospective observational study on WAD patients from two EDs in Verona (Italy). Patients in the earlier acute phase of WAD (within 48 h from the trauma) were included; those with serious conditions (WAD IV) were excluded. As an end point, we considered patients who returned to the ED complaining of WAD symptoms within three months as positive outcome for WAD persistence. Results: 2162 patients were included; of those, 85.4% (n = 1847/2162) received a soft cervical collar prescription. Further, 8.4% (n = 156/1847) of those with a soft cervical collar prescription, and 2.5% (n = 8/315) of those without a soft cervical collar (p < 0.001) returned to the ED within three months. The use of the soft cervical collar was an independent risk factor for ED return within three months, with an OR, adjusted for possible clinical confounders, equal to 3.418 (95% CI 1.653–7.069; p < 0.001). After the propensity score matching, 25.5% of the patients (n = 25/98) using the soft cervical collar returned to the ED at three months, compared to the 6.1% (n = 6/98) that did not adopt the soft cervical collar. The use of a soft cervical collar was associated with ED return with an OR = 4.314 (95% CI 2.066–11.668; p = 0.001). Conclusions: Our study shows that the positioning of the soft collar in a cohort of patients with acute WAD, following a rear-end car collision, is an independent potential risk factor to the return to the ED. Clinically, the use of the collar is a non-recommended practice and seems to be related to an increased risk of delayed recovery. There is a need to inform healthcare providers involved in the ED of the aim to limit the use of the soft cervical collar. A closer collaboration between clinicians (e.g., physicians, physical therapists, nurses) is suggested in the ED. Future primary studies should determine differences between having used or not having used the collar, and compare early physical therapy in the ED compared with the utilization of the collar.

Soft-collar use in rehabilitation of whiplash-associated disorders - A systematic review and meta-analysis

BACKGROUND

Active rehabilitation of Whiplash Associated Disorders (WAD) is favoured over passive modalities such as soft-collars. However, the effectiveness of soft-collar use remains unclear.

OBJECTIVE

To investigate the effectiveness of soft-collar use on pain and disability in WAD.

DESIGN

Systematic review.

METHOD

Databases (AMED, CINAHL Complete, Cochrane Library, Embase, Medline, PEDro, PsycINFO, PubMed, SPORTDiscus) were searched for guidelines, reviews and RCTs on soft-collar use as part of WAD treatment. Reference lists of reviews and guidelines were screened for additional RCTs. Study quality was rated using the PEDro-scale and overall quality of evidence with GRADE.

RESULTS

Four RCTs (n = 409) of fair-good quality (PEDro-scores) were included with three using a soft collar in addition to other conservative treatment while one study compared soft-collar use to act-as-usual. All studies found that an active or act-as-usual approach was more effective in reducing pain intensity compared to soft-collar use, confirmed by meta-analysis (two RCTs with data: SMD of -0.80 (-1.20, -0.41)). No studies reported disability outcomes while contrasting results were found between groups regarding total cervical range of motion (two RCTs with data: SMD of 0.16 (-0.21, 0.54)) or rotation (two RCTs with data: SMD of 0.54 (-0.19, 1.27)). Overall quality of the evidence was low to very low.

CONCLUSION

All four RCTs favoured an active approach/act-as-usual over soft-collar treatment. However, due to methodological concerns and low certainty of evidence, future studies investigating soft collar use in combination with an active rehabilitation strategy for acute/subacute WAD are needed.

Revisiting Risk-stratified Whiplash-exposed Patients 12 to 14 Years After Injury

OBJECTIVE

The objective of this study was to evaluate the long-term predictive value of the Danish Whiplash Group Risk Assessment Score (DWGRAS) with 7 risk strata.

DESIGN

E-questionnaire-based follow-up study (n=927) combining 2 cohorts of whiplash-injured patients, 1 observational (n=187) and 1 interventional randomized controlled trial (n=740).

METHODS

Nine hundred twenty-seven previously healthy persons exposed to acute whiplash injury during motor vehicle collision were sent letter by postal service asking the addressee if they would respond to an E-questionnaire. Outcome measures were: whiplash-related disability, pain, use of medication/nonmedical treatment, work capacity.

RESULTS

The response rate was 37%. Fifty-five percent reported whiplash-related disability. Fourteen percent reported daily symptoms. A strong relationship was found between risk strata and impact of event and between risk strata and disabling symptoms.

CONCLUSIONS

Internal and long-term validation of DWGRAS was performed, but a low response rate indicates that results should be interpreted with caution. Furthermore, external validation needs to be done in long-term studies. An receiver operating characteristics curve of 0.73 (95% confidence interval 0.67; 0.79) predicting daily or weekly whiplash-related disability after 12 to 14 years was found using the DWGRAS risk score.

Precollision Medical Diagnoses Predict Chronic Neck Pain Following Acute Whiplash Trauma

OBJECTIVES

The reason why some individuals develop chronic symptoms, whiplash-associated disorder, following whiplash trauma is poorly understood. We explored whether precollision pain-related diagnoses, medically unexplained symptoms, and psychiatric diagnoses are related to whiplash-associated disorder.

MATERIALS AND METHODS

A cohort of 719 individuals exposed to whiplash trauma and subsequently experiencing symptoms within 72 hours (whiplash-exposed cohort) and 3595 matched controls were included in this observational prospective study. At 12 months postcollision, the whiplash-exposed cohort rated their neck pain using the Visual Analog Scale. Data on health were obtained from the Danish National Patient Register for the whiplash-exposed cohort and for the controls for a 5-year period before collision.

RESULTS

The whiplash-exposed cohort had significantly increased incidences of precollision pain-related diagnoses: χ(1)=17.42, P<0.001 and medically unexplained symptoms: χ(1)=22.2, P<0.001 but not psychiatric diagnoses: χ(1)=3.60, P>0.05 compared with controls in the 5-year period. Participants from the whiplash-exposed cohort with precollision pain-related diagnoses (odds ratio=2.46; 95% confidence interval, 1.39; 4.35) and medically unexplained symptoms (odds ratio, 1.72; 95% confidence interval, 1.04; 2.84) had significantly increased odds for neck pain at follow-up.

DISCUSSION

Precollision pain and medically unexplained symptoms predict chronic neck pain following whiplash trauma. This may indicate that a sensitization process was initiated before the collision or that individuals with precollision low threshold for contacting health care services maintain this behavior postcollision. The collision may trigger existing individual vulnerabilities that constitute to be a risk factor for chronic whiplash.

Clinical Characteristics and Patient-Reported Outcomes of Primary Care Physiotherapy in Patients with Whiplash-Associated Disorders: A Longitudinal Observational Study

BACKGROUND

Whiplash-associated disorders (WADs) constitute a state of health characterized by a wide diversity of symptoms as a result of impairments of functions, activity limitations, and participation restrictions. Patient-reported outcome measurements (PROMs) and patient-reported outcomes (PROs) seem appropriate when describing and evaluating the health status of patients with WAD.

AIM

To measure the use of PROMs and PROs as quality indicators in clinical reasoning, and to analyze and evaluate pre- and post-treatment 'pain intensity' and 'functioning', and for 'perceived improvement' in patients with WAD in primary care physiotherapy practice by year of referral, with the phase after accident and prognostic health profile embedded in the clinical reasoning process.

MATERIALS AND METHODS

Data were collected over a period of 10 years. Pain intensity, functioning, and perceived improvement were measured using the Visual Analogue Scale for Pain (VAS-P), the Neck Disability Index (NDI) and the Global Perceived Effect scale (GPE). Pre- and post-treatment mean differences were tested for statistical significance and compared to minimal clinically important differences (MCID). Effect sizes were expressed as Cohen's d. Multivariable regression analysis was performed to explore independent associations of year of referral, phase after the accident, and the patient's prognostic health profile with post-treatment pain intensity and functioning.

RESULTS

A consecutive sample of 523 patients was included. Pre- and post-treatment mean differences on VAS-P and NDI were statistically significant (P<0.000) and clinically relevant, with 'large' effect sizes for pain intensity and functioning. MCIDs were achieved by 80% for VAS-P and for 60% for NDI. Year of referral and phase after the accident were independently associated with worse post-treatment functioning. About half of the patients (n=241 [46.1%]) perceived themselves as improved.

CONCLUSION

The PROMs and PROs pain intensity, functioning and perceived improvement were integrated as quality indicators in the physiotherapy clinical reasoning process for patients with WAD. Significant differences in pain intensity and functioning were found but were unrelated to year of referral, phase after whiplash-related injury or prognostic health profile. The MCID VAS-P scores did not differ depending on experienced pain.

Development of an Internet-delivered educational video for acute whiplash injuries

Objective

To describe the development of a preventive educational video for patients exposed to whiplash trauma following motor vehicle accidents.

Methods

The development followed a systematic approach and was theory-driven supplemented with available empirical knowledge. The specific content was developed by a multidisciplinary group involving health professionals and visual production specialists.

Results

A 14-min educational video was created. The video content focuses on stimulating adaptive recovery expectations and preventing maladaptive illness beliefs. The video presents a multifactorial model for pain incorporating physiological and cognitive-behavioural aspects, advice on pain relief, and exercises. Subjects interviewed for a qualitative evaluation found the video reassuring and that it aligned well with verbal information received in the hospital.

Conclusions

The development of the visual educational intervention benefitted from a systematic development approach entailing both theoretical and research-based knowledge. The sparse evidence on educational information for acute whiplash trauma posed a challenge for creating content. Further knowledge is required regarding what assists recovery in the early stages of whiplash injuries in order to improve the development of educational interventions.

Are Nonpharmacologic Pain Interventions Effective at Reducing Pain in Adult Patients Visiting the Emergency Department? A Systematic Review and Meta-analysis

OBJECTIVES

Pain is a common complaint in the emergency department (ED). Its management currently depends heavily on pharmacologic treatment, but evidence suggests that nonpharmacologic interventions may be beneficial. The purpose of this systematic review and meta-analysis was to assess whether nonpharmacologic interventions in the ED are effective in reducing pain.

METHODS

We conducted a systematic review of the literature on all types of nonpharmacologic interventions in the ED with pain reduction as an outcome. We performed a qualitative summary of all studies meeting inclusion criteria and meta-analysis of randomized controlled studies measuring postintervention changes in pain. Interventions were divided by type into five categories for more focused subanalyses.

RESULTS

Fifty-six studies met inclusion criteria for summary analysis. The most studied interventions were acupuncture (10 studies) and physical therapy (six studies). The type of pain most studied was musculoskeletal pain (34 studies). Most (42 studies) reported at least one improved outcome after intervention. Of these, 23 studies reported significantly reduced pain compared to control, 24 studies showed no difference, and nine studies had no control group. Meta-analysis included 22 qualifying randomized controlled trials and had a global standardized mean difference of -0.46 (95% confidence interval = -0.66 to -0.27) in favor of nonpharmacologic interventions for reducing pain.

CONCLUSION

Nonpharmacologic interventions are often effective in reducing pain in the ED. However, most existing studies are small, warranting further investigation into their use for optimizing ED pain management.

Factors in Patient Responsiveness to Directional Preference-Matched Treatment of Neck Pain With or Without Upper Extremity Radiation

PURPOSE

Patient-related predictive factors in responsiveness to directional preference therapy for neck pain with or without upper extremity radiation (NP/R) have not been reported. A directional preference is any neck movement that, when performed repeatedly to end range, results in centralization and/or alleviation of NP/R. It was hypothesized that patient compliance with a prescribed, directional preference-matched home exercise program would improve positive responsiveness to NP/R treatment.

METHODS

Patient-related factors thought to affect responsiveness to care were collected retrospectively from charts and de-identified for patients with NP/R who underwent chiropractic treatment at a multispecialty spine clinic from January 2014 through June 2015. Responsiveness was measured by calculating the percentage change in Neck Bournemouth Questionnaire (NBQ) scores over treatment time. Multiple linear regression was used to identify factors associated with positive responsiveness.

RESULTS

Mean percentage change in patient NBQ score from initial intake to discharge was 50% (standard deviation: 32%). Of 104 patients meeting study inclusion criteria, 86 (83%) reported experiencing improvement after the first treatment session. Bivariate analysis of patient characteristics by compliance with directional preference-matched exercise indicated that compliant patients (n=95, 91%) demonstrated significantly greater responsiveness to care than did noncompliant patients, at 55% versus 25% change in NBQ score, respectively (P=0.0041). Four factors were statistically significant predictors of patient responsiveness to directional preference therapy for NP/R: patient compliance with directional preference-matched exercise (P=0.0023), patient age (P=0.0029), condition chronicity (P<0.0001), and whether the patient reported improvement of symptoms following initial treatment session (P=0.0003).

CONCLUSIONS

The results of this study suggest that patient compliance with directional preference exercise is associated with patient responsiveness to conservative treatment of NP/R, as are age, chronicity and report of immediate symptom improvement.

Immediate improvement in the cranio-cervical flexion test associated with MDT-based interventions: a case report

The patient in this case study presented with constant idiopathic neck pain and left lower scapular pain (greater than 3 months) and was treated based on the principles of Mechanical Diagnosis and Therapy (MDT). Retraction exercises produced centralization of the lower scapular pain to the upper part of the scapula at the initial visit. At the first visit, the performance level on the Cranio-Cervical Flexion Test (CCFT) was ≤20 mmHg before the treatment. At the conclusion of the treatment during which centralization occurred, the CCFT level improved to 24 mmHg. At the second visit, all symptoms were abolished and cervical range of motion (ROM) was fully restored by performing repeated extension in lying from a retracted position with clinician's traction. The CCFT levels before and immediately after the treatment were 24 and 26 mmHg, respectively. At the third visit (1 week after the initial visit), he noted that all daily activities could be performed without pain. The CCFT level was maintained at 26mmHg. The patient in this study showed immediate improvement in the CCFT through the treatments based on MDT. This suggests a possible link between MDT interventions and motor control of the cervical spine and a need to further investigate this relationship.

Management of neck pain and associated disorders: A clinical practice guideline from the Ontario Protocol for Traffic Injury Management (OPTIMa) Collaboration

PURPOSE

To develop an evidence-based guideline for the management of grades I-III neck pain and associated disorders (NAD).

METHODS

This guideline is based on recent systematic reviews of high-quality studies. A multidisciplinary expert panel considered the evidence of effectiveness, safety, cost-effectiveness, societal and ethical values, and patient experiences (obtained from qualitative research) when formulating recommendations. Target audience includes clinicians; target population is adults with grades I-III NAD <6 months duration.

RECOMMENDATION 1

Clinicians should rule out major structural or other pathologies as the cause of NAD. Once major pathology has been ruled out, clinicians should classify NAD as grade I, II, or III.

RECOMMENDATION 2

Clinicians should assess prognostic factors for delayed recovery from NAD.

RECOMMENDATION 3

Clinicians should educate and reassure patients about the benign and self-limited nature of the typical course of NAD grades I-III and the importance of maintaining activity and movement. Patients with worsening symptoms and those who develop new physical or psychological symptoms should be referred to a physician for further evaluation at any time during their care.

RECOMMENDATION 4

For NAD grades I-II ≤3 months duration, clinicians may consider structured patient education in combination with: range of motion exercise, multimodal care (range of motion exercise with manipulation or mobilization), or muscle relaxants. In view of evidence of no effectiveness, clinicians should not offer structured patient education alone, strain-counterstrain therapy, relaxation massage, cervical collar, electroacupuncture, electrotherapy, or clinic-based heat.

RECOMMENDATION 5

For NAD grades I-II >3 months duration, clinicians may consider structured patient education in combination with: range of motion and strengthening exercises, qigong, yoga, multimodal care (exercise with manipulation or mobilization), clinical massage, low-level laser therapy, or non-steroidal anti-inflammatory drugs. In view of evidence of no effectiveness, clinicians should not offer strengthening exercises alone, strain-counterstrain therapy, relaxation massage, relaxation therapy for pain or disability, electrotherapy, shortwave diathermy, clinic-based heat, electroacupuncture, or botulinum toxin injections.

RECOMMENDATION 6

For NAD grade III ≤3 months duration, clinicians may consider supervised strengthening exercises in addition to structured patient education. In view of evidence of no effectiveness, clinicians should not offer structured patient education alone, cervical collar, low-level laser therapy, or traction. RECOMMENDATION 7: For NAD grade III >3 months duration, clinicians should not offer a cervical collar. Patients who continue to experience neurological signs and disability more than 3 months after injury should be referred to a physician for investigation and management. RECOMMENDATION 8: Clinicians should reassess the patient at every visit to determine if additional care is necessary, the condition is worsening, or the patient has recovered. Patients reporting significant recovery should be discharged.

Pain and pain tolerance in whiplash-associated disorders: A population-based study

Background

Pain is a cardinal symptom in individuals with whiplash‐associated disorders (WAD). We aimed to compare pain characteristics between individuals with WAD and individuals reporting chronic pain from other causes, and to determine whether potential differences were accounted for by experimental pain tolerance.

Methods

Data from the 6th Tromsø Study (2007–2008, n = 12,981) were analysed. The number of painful locations was compared between individuals with WAD and individuals reporting chronic pain from other causes using negative binomial regression, pain frequency using multinomial logistic regression and pain intensity using multiple linear regression. Differences in experimental pain tolerance (cold pressor test) were tested using Cox regression; one model compared individuals with WAD to those with chronic pain from other causes, one compared the two groups with chronic pain to individuals without chronic pain. Subsequently, regression models investigating clinical pain characteristics were adjusted for pain tolerance.

Results

Of individuals with WAD, 96% also reported other causes for pain. Individuals with WAD reported a higher number of painful locations [median (inter‐quartile range): 5 (3.5–7) vs. 3 (2–5), p < 0.001] and higher pain intensity (crude mean difference = 0.78, p < 0.001) than individuals with chronic pain from other causes. Pain tolerance did not differ between these two groups. Compared to individuals without chronic pain, individuals with WAD and individuals with chronic pain from other causes had reduced pain tolerance.

Conclusions

Individuals with WAD report more additional causes of pain, more painful locations and higher pain intensity than individuals with chronic pain from other causes. The increased pain reporting was not accounted for by pain tolerance.

Manipulation and mobilisation for neck pain contrasted against an inactive control or another active treatment

BACKGROUND

Manipulation and mobilisation are commonly used to treat neck pain. This is an update of a Cochrane review first published in 2003, and previously updated in 2010.

OBJECTIVES

To assess the effects of manipulation or mobilisation alone compared wiith those of an inactive control or another active treatment on pain, function, disability, patient satisfaction, quality of life and global perceived effect in adults experiencing neck pain with or without radicular symptoms and cervicogenic headache (CGH) at immediate- to long-term follow-up. When appropriate, to assess the influence of treatment characteristics (i.e. technique, dosage), methodological quality, symptom duration and subtypes of neck disorder on treatment outcomes.

SEARCH METHODS

Review authors searched the following computerised databases to November 2014 to identify additional studies: the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE and the Cumulative Index to Nursing and Allied Health Literature (CINAHL). We also searched ClinicalTrials.gov, checked references, searched citations and contacted study authors to find relevant studies. We updated this search in June 2015, but these results have not yet been incorporated.

SELECTION CRITERIA

Randomised controlled trials (RCTs) undertaken to assess whether manipulation or mobilisation improves clinical outcomes for adults with acute/subacute/chronic neck pain.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies, abstracted data, assessed risk of bias and applied Grades of Recommendation, Assessment, Development and Evaluation (GRADE) methods (very low, low, moderate, high quality). We calculated pooled risk ratios (RRs) and standardised mean differences (SMDs).

MAIN RESULTS

We included 51 trials (2920 participants, 18 trials of manipulation/mobilisation versus control; 34 trials of manipulation/mobilisation versus another treatment, 1 trial had two comparisons). Cervical manipulation versus inactive control: For subacute and chronic neck pain, a single manipulation (three trials, no meta-analysis, 154 participants, ranged from very low to low quality) relieved pain at immediate- but not short-term follow-up. Cervical manipulation versus another active treatment: For acute and chronic neck pain, multiple sessions of cervical manipulation (two trials, 446 participants, ranged from moderate to high quality) produced similar changes in pain, function, quality of life (QoL), global perceived effect (GPE) and patient satisfaction when compared with multiple sessions of cervical mobilisation at immediate-, short- and intermediate-term follow-up. For acute and subacute neck pain, multiple sessions of cervical manipulation were more effective than certain medications in improving pain and function at immediate- (one trial, 182 participants, moderate quality) and long-term follow-up (one trial, 181 participants, moderate quality). These findings are consistent for function at intermediate-term follow-up (one trial, 182 participants, moderate quality). For chronic CGH, multiple sessions of cervical manipulation (two trials, 125 participants, low quality) may be more effective than massage in improving pain and function at short/intermediate-term follow-up. Multiple sessions of cervical manipulation (one trial, 65 participants, very low quality) may be favoured over transcutaneous electrical nerve stimulation (TENS) for pain reduction at short-term follow-up. For acute neck pain, multiple sessions of cervical manipulation (one trial, 20 participants, very low quality) may be more effective than thoracic manipulation in improving pain and function at short/intermediate-term follow-up. Thoracic manipulation versus inactive control: Three trials (150 participants) using a single session were assessed at immediate-, short- and intermediate-term follow-up. At short-term follow-up, manipulation improved pain in participants with acute and subacute neck pain (five trials, 346 participants, moderate quality, pooled SMD -1.26, 95% confidence interval (CI) -1.86 to -0.66) and improved function (four trials, 258 participants, moderate quality, pooled SMD -1.40, 95% CI -2.24 to -0.55) in participants with acute and chronic neck pain. A funnel plot of these data suggests publication bias. These findings were consistent at intermediate follow-up for pain/function/quality of life (one trial, 111 participants, low quality). Thoracic manipulation versus another active treatment: No studies provided sufficient data for statistical analyses. A single session of thoracic manipulation (one trial, 100 participants, moderate quality) was comparable with thoracic mobilisation for pain relief at immediate-term follow-up for chronic neck pain. Mobilisation versus inactive control: Mobilisation as a stand-alone intervention (two trials, 57 participants, ranged from very low to low quality) may not reduce pain more than an inactive control. Mobilisation versus another active treatment: For acute and subacute neck pain, anterior-posterior mobilisation (one trial, 95 participants, very low quality) may favour pain reduction over rotatory or transverse mobilisations at immediate-term follow-up. For chronic CGH with temporomandibular joint (TMJ) dysfunction, multiple sessions of TMJ manual therapy (one trial, 38 participants, very low quality) may be more effective than cervical mobilisation in improving pain/function at immediate- and intermediate-term follow-up. For subacute and chronic neck pain, cervical mobilisation alone (four trials, 165 participants, ranged from low to very low quality) may not be different from ultrasound, TENS, acupuncture and massage in improving pain, function, QoL and participant satisfaction at immediate- and intermediate-term follow-up. Additionally, combining laser with manipulation may be superior to using manipulation or laser alone (one trial, 56 participants, very low quality).

AUTHORS' CONCLUSIONS

Although support can be found for use of thoracic manipulation versus control for neck pain, function and QoL, results for cervical manipulation and mobilisation versus control are few and diverse. Publication bias cannot be ruled out. Research designed to protect against various biases is needed. Findings suggest that manipulation and mobilisation present similar results for every outcome at immediate/short/intermediate-term follow-up. Multiple cervical manipulation sessions may provide better pain relief and functional improvement than certain medications at immediate/intermediate/long-term follow-up. Since the risk of rare but serious adverse events for manipulation exists, further high-quality research focusing on mobilisation and comparing mobilisation or manipulation versus other treatment options is needed to guide clinicians in their optimal treatment choices.

Value-based cognitive-behavioural therapy for the prevention of chronic whiplash associated disorders: protocol of a randomized controlled trial

BACKGROUND

Whiplash injury is the most common traffic-related injury affecting thousands of people every year. Conservative treatments have not proven effective in preventing persistent symptoms and disability after whiplash injury. Early established maladaptive pain behaviours within the first weeks after the injury may explain part of the transition from acute to chronic whiplash associated disorder (WAD). Hence, early targeting of psychological risk factors such as pain catastrophizing, fear-avoidance-beliefs, depression, and symptoms of posttraumatic stress disorder (PTSD) may be important in preventing the development of chronic WAD. Some evidence exists that targeting fear-avoidance beliefs and PTSD with exposure strategies and value-based actions may prevent development of persistent disability after whiplash injury. Yet, the results have to be tested in a randomized controlled trial (RCT). The primary objective of the present study is to test whether a specifically tailored value-based cognitive-behavioural therapy program (V-CBT) is able to prevent the development of persistent disability, pain, and psychological distress if delivered within the first three months after a whiplash injury.

METHODS/DESIGN

The current study is a two-armed randomized controlled study with a crossover design. Group A is scheduled for V-CBT within one week of randomization and group B with a delayed onset 3 months after randomization.

DISCUSSION

If the study detects significant effects of V-CBT as a preventive intervention, the study will provide new insights of preventive treatment for patients with WAD and thereby serve as an important step towards preventing the chronic condition.

Sick Leave within 5 Years of Whiplash Trauma Predicts Recovery: A Prospective Cohort and Register-Based Study

BACKGROUND

10-22% of individuals sustaining whiplash trauma develop persistent symptoms resulting in reduced working ability and decreased quality of life, but it is poorly understood why some people do not recover. Various collision and post-collision risk factors have been studied, but little is known about pre-collision risk factors. In particular, the impact of sickness and socioeconomic factors before the collision on recovery is sparsely explored. The aim of this study was to examine if welfare payments received within five years pre-collision predict neck pain and negative change in provisional situation one year post-collision.

METHODS AND FINDINGS

719 individuals with acute whiplash trauma consecutively recruited from emergency departments or primary care after car accidents in Denmark completed questionnaires on socio-demographic and health factors immediately after the collision. After 12 months, a visual analogue scale on neck pain intensity was completed. 3595 matched controls in the general population were sampled, and national public register data on social benefits and any other welfare payments were obtained for participants with acute whiplash trauma and controls from five years pre-collision to 15 months after. Participants with acute whiplash trauma who had received sickness benefit for more than 12 weeks pre-collision had increased odds for negative change in future provisional situation (Odds Ratio (OR) (95% Confidence Interval (CI) = 3.8 (2.1;7.1)) and future neck pain (OR (95%CI) = 3.3 (1.8;6.3)), controlling for other known risk factors. Participants with acute whiplash trauma had weaker attachment to labour market (more weeks of sick leave (χ2(2) = 36.7, p < 0.001) and unemployment (χ2(2) = 12.5, p = 0.002)) pre-collision compared with controls. Experiencing a whiplash trauma raised the odds for future negative change in provisional situation (OR (95%CI) = 3.1 (2.3;4.4)) compared with controls.

CONCLUSIONS

Sick leave before the collision strongly predicted prolonged recovery following whiplash trauma. Participants with acute whiplash trauma had weaker attachment to labour market pre-collision compared with the general population. Neck pain at inclusion predicted future neck pain. Acute whiplash trauma may trigger pre-existing vulnerabilities increasing risk of developing whiplash-associated disorders.

Initial healthcare and coping preferences are associated with outcome 1 year after whiplash trauma: a multicentre 1-year follow-up study

OBJECTIVE

Individuals exposed to whiplash collisions have to cope with the stressful event as well as early physical symptoms. As in other chronic pain conditions, coping has been associated with outcome after whiplash. In this study, our aim was to examine whether initial coping preferences were associated with the development of chronic whiplash.

DESIGN

Prospective study.

SETTING

Primary care.

METHODS

740 acute whiplash patients were recruited from emergency units and general practitioners after car collisions in Denmark. Within 10 days postinjury, participants were asked what they believed could help them get better. At 12-month follow-up, the level of neck pain and capability to work was obtained. Whether coping preferences (baseline) were associated with outcome was investigated using multiple regression analyses.

RESULTS

Persistent neck pain was most strongly associated with preferring medications (mean difference=1.24 (95% CI 0.67 to 1.82)) and sickness absence (mean difference=1.18 (95% CI 0.53 to 1.82)). Reduced work capability was most strongly associated with preferring medications (OR=3.53 (95% CI 2.13 to 5.86)), sickness absence (OR=3.05 (95% CI 1.80 to 5.17)) and being referred to a physiotherapist/chiropractor (OR=3.03 (95% CI 1.33 to 6.91)). Active coping was associated with better outcomes: Participants preferring to change their lifestyle were protected against reduced work capability (OR=0.11 (95% CI 0.01 to 0.78)). Individuals who wanted to keep living as usual only (no other preference reported) were protected against neck pain (mean difference -1.62 (95% CI -2.39 to -0.84)) and reduced work capability (OR=0.09 (95% CI 0.01 to 0.64)).

CONCLUSIONS

A simple nine-item measure of coping preferences is associated with the development of chronic neck pain and reduced capability to work following whiplash trauma and may be used to identify individuals at risk of poor recovery.

Mechanical diagnosis and therapy has similar effects on pain and disability as 'wait and see' and other approaches in people with neck pain: a systematic review

QUESTIONS

In people with neck pain, does Mechanical Diagnosis and Therapy (MDT) reduce pain and disability more than 'wait and see'? Does MDT reduce pain and disability more than other interventions? Are any differences in effect clinically important?

DESIGN

Systematic review of randomised trials with meta-analysis.

PARTICIPANTS

People with neck pain.

INTERVENTION

MDT.

OUTCOME MEASURES

Pain intensity and disability due to neck pain in the short (< 3 months), intermediate (< 1 year) and long term (≥ 1 year).

RESULTS

Five trials were included. Most comparisons demonstrated mean differences in effect that favoured MDT over wait-and-see controls or other interventions, although most were statistically non-significant. For pain, all comparisons had a 95% confidence interval (CI) with lower limits that were less than 20 on a scale of 0 to 100, which suggests that the difference may not be clinically important. For disability, even the upper limits of the 95% CI were below this threshold, confirming that the differences are not clinically important. In all of the trials, some or all of the treating therapists did not have the highest level of MDT training.

CONCLUSION

The additional benefit of MDT compared with the wait-and-see approach or other therapeutic approaches may not be clinically important in terms of pain intensity and is not clinically important in terms of disability. However, these estimates of the effect of MDT may reflect suboptimal training of the treating therapists. Further research could improve the precision of the estimates and assess whether the extent of training in MDT influences its effect.

An early intervention programme had no detectable influence on the health status of people with musculoskeletal injuries following road traffic crashes: comparative study

OBJECTIVE

To compare the health status of people with minor injuries from road traffic crashes that are exposed to an early, active intervention programme (intervention group) with those receiving usual care (control group) over a 12 month period.

DESIGN

Prospective comparative study using sequential cohorts.

SUBJECTS

People presenting to hospital emergency departments with mild to moderate musculoskeletal injuries following road traffic crashes.

MAIN OUTCOME MEASURES

Physical Component Score (PCS) and Mental Component Score (MCS) of the Short Form 36 (SF-36) health status measure; Hospital Anxiety and Depression Scale (HADS) and the Functional Rating Index (FRI) recorded immediately post-crash, at 6 months and at 12 months after injury.

RESULTS

There were 95 participants allocated to the control group and 98 allocated to the intervention group. Participants were enrolled at a mean of 9.3 days following the crash. There were no significant differences in baseline health measures between the groups. Apart from a small improvement in anxiety for the intervention group, there were no significant differences in health status between the groups. Twenty percent of participants in the intervention group received treatment from external healthcare providers that was inconsistent with the recommendations of the intervention programme.

CONCLUSIONS

The intervention programme failed to result in a clinically significant improvement in health outcomes compared with usual care. There is some evidence to suggest that the intervention had some psychological benefits, as evidenced by the small improvement in anxiety levels. Limited adherence, frequent use of co-interventions, or other factors (such as intervention content or intensity) may have reduced its effect.

Psychological Care, Patient Education, Orthotics, Ergonomics and Prevention Strategies for Neck Pain: An Systematic Overview Update as Part of the ICON Project

OBJECTIVES

To conduct an overview on psychological interventions, orthoses, patient education, ergonomics, and 1⁰/2⁰ neck pain prevention for adults with acute-chronic neck pain.

SEARCH STRATEGY

Computerized databases and grey literature were searched (2006-2012).

SELECTION CRITERIA

Systematic reviews of randomized controlled trials (RCTs) on pain, function/disability, global perceived effect, quality-of-life and patient satisfaction were retrieved.

DATA COLLECTION & ANALYSIS

Two independent authors selected articles, assessed risk of bias using AMSTAR tool and extracted data. The GRADE tool was used to evaluate the body of evidence and an external panel to provide critical review.

MAIN RESULTS

We retrieved 30 reviews (5-9 AMSTAR score) reporting on 75 RCTs with the following moderate GRADE evidence. For acute whiplash associated disorder (WAD), an education video in emergency rooms (1RCT, 405participants] favoured pain reduction at long-term follow-up thus helping 1 in 23 people [Standard Mean Difference: -0.44(95%CI: -0.66 to -0.23)). Use of a soft collar (2RCTs, 1278participants) was not beneficial in the long-term. For chronic neck pain, a mind-body intervention (2RCTs, 1 meta-analysis, 191participants) improved short-term pain/function in 1 of 4 or 6 participants. In workers, 2-minutes of daily scapula-thoracic endurance training (1RCT, 127participants) over 10 weeks was beneficial in 1 of 4 participants. A number of psychosocial interventions, workplace interventions, collar use and self-management educational strategies were not beneficial.

REVIEWERS' CONCLUSIONS

Moderate evidence exists for quantifying beneficial and non-beneficial effects of a limited number of interventions for acute WAD and chronic neck pain. Larger trials with more rigorous controls need to target promising interventions.

High power laser therapy treatment compared to simple segmental physical rehabilitation in whiplash injuries (1° and 2° grade of the Quebec Task Force classification) involving muscles and ligaments

INTRODUCTION

whiplash is a frequent post traumatic pathology caused by muscle, tendon and capsular elements over stretching. The authors conducted a short term prospective randomised study to test the effectiveness of a multi wave High Power Laser Therapy (HPLT) versus conventional simple segmental physical rehabilitation (PT) included in Italian tariff nomenclature performance physiotherapy Study Design: prospective randomised study (Level II).

MATERIAL AND METHODS

the authors identified 135 homogeneous patients with whiplash grade 1 - 2 of the Quebec Task Force classification (QTFC). INAIL, the Italian National Workers Insurance, based in Milan, was reliable source for identifying patients. All patients with whiplash injuries grade 1 or 2 QTFC, were eligible for the study, starting from April 28 2010 to September 30 2010. Patients referred to a Coordinator (C.M.) who applied the inclusion and exclusion criteria. Patients who agreed to participate were randomly assigned to one of the two treatment groups. Dates for initial treatment session were arranged, including cervical spine X-ray, and assessment. Each patient gave informed consent for participation and agreed to adopt only the study treatment for 6 weeks. Group A (84 patients) was treated with High Power Laser Therapy (HPLT), Group B (51 patients) received conventional simple segmental physical rehabilitation (PT). During the treatment period, no other electro-medical therapy, analgesics or anti-inflammatory drugs were allowed. All patients were assessed at baseline (T0) and at the end of the treatment period (T1) using a Visual Analogical Scale (VAS), (T2) the date of return to work was registered afterwards.

RESULTS

there was a reduction in VAS pain scores at T1. Group A (VAS = 20) Group B (VAS = 34,8) (p =0.0048). Laser treatment allowed quick recovery and return to work (T2). Group A after 48 days against 66 days of Group B (p=0.0005).

CONCLUSIONS

results suggest that High Power Laser Therapy - is an effective treatment in patients with whiplash injury, compared to conventional simple segmental physical rehabilitation.

Health, social, and economic consequences of neck injuries: a controlled national study evaluating societal effects on patients and their partners

STUDY DESIGN

National register-based matched case-control study.

OBJECTIVE

The aim of this study was to estimate the direct and indirect costs of neck injuries, except fractures, in a national sample of patients and their spouses.

SUMMARY OF BACKGROUND DATA

Despite neck injuries causing significant socioeconomic burdens, there is insufficient information about the time course, as well as the effect on their spouses.

METHODS

Using records from the Danish National Patient Registry 1998-2009, all patients with a diagnosis of neck injury and their spouses were identified and compared with randomly chosen controls matched for age, sex, geographical area, and civil status. Direct costs included frequency of primary and hospital sector contacts and procedures and medication. Indirect costs included the effect on labor supply. Social transfer payments were included to illustrate the effect on national accounts. All cost data were extracted from national databases.

RESULTS

The register contributed 94,224 patients, and 372,341 matched controls were identified. The percentages of married or cohabiting individuals were approximately 47.5% in both groups. Patients with neck injury had significantly higher rates of health-related contacts, medication use, and higher socioeconomic costs than controls. To a lesser extent, they also had lower employment rates, and those employed generally had lower incomes. Furthermore, the patients had already presented negative social- and health-related status up to 11 years before the first diagnosis, which became more pronounced for those with the highest costs. The health effects on costs were present regardless of age group and sex, and it was also seen for the patients' spouses.

CONCLUSION

Neck injuries are associated with major socioeconomic consequences for patients, their spouses, and the society. However, the increased expenses during subsequent years cannot be explained by the injury alone, because these patients already had elevated expenses prior to the injury. This indicates some selection of increased vulnerability for both patients and their spouses.

Risk factors for persistent problems following acute whiplash injury: update of a systematic review and meta-analysis

STUDY DESIGN

Systematic review and meta-analysis.

OBJECTIVE

To update a previous review and meta-analysis on risk factors for persistent problems following whiplash secondary to a motor vehicle accident.

BACKGROUND

Prognosis in whiplash-associated disorder (WAD) has become an active area of research, perhaps owing to the difficulty of treating chronic problems. A previously published review and meta-analysis of prognostic factors included primary sources up to May 2007. Since that time, more research has become available, and an update to that original review is warranted.

METHODS

A systematic search of international databases was conducted, with rigorous inclusion criteria focusing on studies published between May 2007 and May 2012. Articles were scored, and data were extracted and pooled to estimate the odds ratio for any factor that had at least 3 independent data points in the literature.

RESULTS

Four new cohorts (n = 1121) were identified. In combination with findings of a previous review, 12 variables were found to be significant predictors of poor outcome following whiplash, 9 of which were new (n = 2) or revised (n = 7) as a result of additional data. The significant variables included high baseline pain intensity (greater than 5.5/10), report of headache at inception, less than postsecondary education, no seatbelt in use during the accident, report of low back pain at inception, high Neck Disability Index score (greater than 14.5/50), preinjury neck pain, report of neck pain at inception (regardless of intensity), high catastrophizing, female sex, WAD grade 2 or 3, and WAD grade 3 alone. Those variables robust to publication bias included high pain intensity, female sex, report of headache at inception, less than postsecondary education, high Neck Disability Index score, and WAD grade 2 or 3. Three existing variables (preaccident history of headache, rear-end collision, older age) and 1 additional novel variable (collision severity) were refined or added in this updated review but showed no significant predictive value.

CONCLUSION

This review identified 2 additional prognostic factors and refined the estimates of 7 previously identified factors, bringing the total number of significant predictors across the 2 reviews to 12. These factors can be easily identified in a clinical setting to provide estimates of prognosis following whiplash.

A new stratified risk assessment tool for whiplash injuries developed from a prospective observational study

OBJECTIVES

An initial stratification of acute whiplash patients into seven risk-strata in relation to 1-year work disability as primary outcome is presented.

DESIGN

The design was an observational prospective study of risk factors embedded in a randomised controlled study.

SETTING

Acute whiplash patients from units, general practitioners in four Danish counties were referred to two research centres.

PARTICIPANTS

During a 2-year inclusion period, acute consecutive whiplash-injured (age 18-70 years, rear-end or frontal-end car accident and WAD (whiplash-associated disorders) grades I-III, symptoms within 72 h, examination prior to 10 days postinjury, capable of written/spoken Danish, without other injuries/fractures, pre-existing significant somatic/psychiatric disorder, drug/alcohol abuse and previous significant pain/headache). 688 (438 women and 250 men) participants were interviewed and examined by a study nurse after 5 days; 605 were completed after 1 year. A risk score which included items of initial neck pain/headache intensity, a number of non-painful complaints and active neck mobility was applied. The primary outcome parameter was 1-year work disability.

RESULTS

The risk score and number of sick-listing days were related (Kruskal-Wallis, p<0.0001). In stratum 1, less than 4%, but in stratum 7, 68% were work-disabled after 1 year. Early work assessment (p<0.0001), impact of the event questionnaire (p<0.0006), psychophysical pain measures being McGill pain questionnaire parameters (p<0.0001), pressure pain algometry (p<0.0001) and palpation (p<0.0001) showed a significant relationship with risk stratification.

ANALYSIS

Findings confirm previous studies reporting intense neck pain/headache and distress as predictors for work disability after whiplash. Neck-mobility was a strong predictor in this study; however, it was a more inconsistent predictor in other studies.

CONCLUSIONS

Application of the risk assessment score and use of the risk strata system may be beneficial in future studies and may be considered as a valuable tool to assess return-to-work following injuries; however, further studies are needed.

The influence of fault on health in the immediate post-crash period following road traffic crashes

OBJECTIVE

To compare the early health status of people who sustained injuries during road traffic crashes (RTC) in which they were at fault (AF), with people who sustained injuries in RTC in which they were not at fault (NAF).

DESIGN

Prospective cohort study.

SUBJECTS

People presenting to the emergency department with mild to moderate musculoskeletal injuries following RTC.

MAIN OUTCOME MEASURES

Physical Component Score (PCS) and Mental Component Score (MCS) of the Short Form 36 (SF-36) health status measure; Hospital Anxiety and Depression Scale (HADS) and the Functional Rating Index (FRI) recorded immediately post-crash.

RESULTS

193 people participated in the study and were enrolled a mean of 9.3 days following the crash. The mean age was 37 years and 60% were female. 71% were NAF. There was a significantly higher number of females in the NAF group (65% compared with 35% males; p<0.001). Neck and back injuries were reported by 90.4% of the NAF group compared to 69.1% of the AF group (p<0.001). There were no significant differences in PCS, FRI or pain intensity between the two groups at a mean of 9.3 days after the crash. The mean MCS for the NAF group was significantly worse than for the AF group (31.4 compared to 37.3; p = 0.005). The SF-36 domain revealed a significantly worse adjusted mean role emotional score for the NAF group (23.4 compared to 32.5, p = 0.002). Females had significantly worse MCS score than males (30.6 and 38.1 respectively; p<0.001) and worse adjusted mean anxiety and depression scores (10 compared to 7.8; p = 0.002 and 7.6 compared to 5.5; p = 0.002 respectively).

CONCLUSIONS

Despite there being no difference in physical health status, the NAF group demonstrated more emotional and mental disturbance than the AF group; and this was significantly worse for females. Treatment strategies should focus on addressing early pain and disability as well as providing appropriate psychological interventions, particularly for people not at fault following RTC.

Patient education for neck pain

BACKGROUND

Neck disorders are common, disabling, and costly. The effectiveness of patient education strategies is unclear.

OBJECTIVES

To assess the short- to long-term effects of therapeutic patient education (TPE) strategies on pain, function, disability, quality of life, global perceived effect, patient satisfaction, knowledge transfer, or behaviour change in adults with neck pain associated with whiplash or non-specific and specific mechanical neck pain with or without radiculopathy or cervicogenic headache.

SEARCH METHODS

We searched computerised bibliographic databases (inception to 11 July 2010).

SELECTION CRITERIA

Eligible studies were randomised controlled trials (RCT) investigating the effectiveness of TPE for acute to chronic neck pain.

DATA COLLECTION AND ANALYSIS

Paired independent review authors conducted selection, data abstraction, and 'Risk of bias' assessment. We calculated risk ratio (RR) and standardised mean differences (SMD). Heterogeneity was assessed; no studies were pooled.

MAIN RESULTS

Of the 15 selected trials, three were rated low risk of bias. Three TPE themes emerged.Advice focusing on activation: There is moderate quality evidence (one trial, 348 participants) that an educational video of advice focusing on activation was more beneficial for acute whiplash-related pain when compared with no treatment at intermediate-term [RR 0.79 (95% confidence interval (CI) 0.59 to 1.06)] but not long-term follow-up [0.89 (95% CI, 0.65 to 1.21)]. There is low quality evidence (one trial, 102 participants) that a whiplash pamphlet on advice focusing on activation is less beneficial for pain reduction, or no different in improving function and global perceived improvement from generic information given out in emergency care (control) for acute whiplash at short- or intermediate-term follow-up. Low to very low quality evidence (nine trials using diverse educational approaches) showed either no evidence of benefit or difference for varied outcomes. Advice focusing on pain & stress coping skills and workplace ergonomics: Very low quality evidence (three trials, 243 participants) favoured other treatment or showed no difference spanning numerous follow-up periods and disorder subtypes.  Low quality evidence (one trial, 192 participants) favoured specific exercise training for chronic neck pain at short-term follow-up.Self-care strategies: Very low quality evidence (one trial, 58 participants) indicated that self-care strategies did not relieve pain for acute to chronic neck pain at short-term follow-up.

AUTHORS' CONCLUSIONS

With the exception of one trial, this review has not shown effectiveness for educational interventions, including advice to activate, advice on stress-coping skills, workplace ergonomics and self-care strategies. Future research should be founded on sound adult learning theory and learning skill acquisition.

Considerations in the physical rehabilitation of patients with whiplash-associated disorders

STUDY DESIGN

Review of research identifying physical impairments in the neuromuscular system in subjects with whiplash-associated disorders.

OBJECTIVE

Review the impairments in movement and neuromuscular function toward constructing research informed exercise programs.

SUMMARY OF BACKGROUND DATA

Pain and injury to the musculoskeletal system result in loss of motion and impaired neuromuscular function which impacts on functional activities, work and quality of life. Therapeutic exercise is a mainstay of rehabilitation, but the nature of the exercises prescribed are currently various and the effect sizes of current programs for patients with whiplash-associated disorders are modest at best.

METHODS

A review was undertaken of research investigating the changes in cervical motion and neuromuscular function to better inform exercise prescription and identify areas for future research. RESULTS.: Reduced range of movement as well as pathological movement patterns (reduced acceleration and velocity, reduced smoothness and irregular axes of neck movement) have been documented in subjects with whiplash-associated disorders. In relation to neuromuscular control, changes have been demonstrated in neck muscles' spatial and temporal relationships as well as in their strength and endurance. The presence or not and the extent of changes is highly variable between individuals and appears to have some relationship to pain intensity. It appears that there is a need for specificity in exercise prescription to address particular impairments rather than the use of generic programs. High pain intensity can modify effects of a therapeutic exercise program.

CONCLUSION

Pain and injury result in reorganization of the motor control strategies of neck muscles and movement. Further research is required to determine if outcomes after a whiplash injury can be improved by using research informed, individually prescribed exercise programs matched to the individual's presentation. Research into best methods of pain management is also required to facilitate physical rehabilitation.

Does early management of whiplash-associated disorders assist or impede recovery?

STUDY DESIGN

Narrative review of the literature and commentary.

OBJECTIVE

To discuss from an epidemiological and sociological perspective whether the early clinical management of whiplash-associated disorders can lead to iatrogenic disability.

SUMMARY OF BACKGROUND DATA

There is a lack of evidence supporting the effectiveness of early rehabilitation care for whiplash-associated disorders.

METHODS

We describe the epidemiological evidence on the effectiveness of early rehabilitation on health outcomes for patients with whiplash-associated disorders and analyze from a sociological perspective how the medicalization of this condition may have contributed to increasing its burden on disability.

RESULTS

The evidence from randomized clinical trials suggests that education, exercise, and mobilization are effective modalities to treat whiplash-associated disorders. However, the evidence from large population-based cohort studies and a pragmatic randomized trial suggests that too much health care and rehabilitation too early after the injury can be associated with delayed recovery and the development of chronic pain and disability. These findings suggest that clinicians may be inadvertently contributing to the development of iatrogenic disability. The epidemiological evidence is supported by the sociological concepts of medicalization, iatrogenesis, and moral hazard.

CONCLUSION

The current evidence suggests that too much health care too early after the injury is associated with delayed recovery. Clinicians need to be educated about the risk of iatrogenic disability.

A comparison of neck movement in the soft cervical collar and rigid cervical brace in healthy subjects

OBJECTIVE

The soft cervical collar has been prescribed for whiplash injury but has been shown to be clinically ineffective. As some authors report superior results for managing whiplash injury with a cervical brace, we were interested in comparing the mechanical effectiveness of the soft collar with a rigid cervical brace. Therefore, the purpose of this study was to measure ranges of motion in subjects without neck pain using a soft cervical collar and a rigid brace compared with no orthosis.

METHODS

Fifty healthy subjects (no neck or shoulder pain) aged 22 to 67 years were recruited for this study. Neck movement was measured using a cervical range of motion goniometer. Active flexion, extension, right and left lateral flexion, and right and left rotation were assessed in each subject under 3 conditions: no collar, a soft collar, and a rigid cervical brace.

RESULTS

The soft collar and rigid brace reduced neck movement compared with no brace or collar, but the cervical brace was more effective at reducing motion. The soft collar reduced movement on average by 17.4%; and the cervical brace, by 62.9%. The effect of the orthoses was not affected by age, although older subjects had stiffer necks.

CONCLUSION

Based on the data of the 50 subjects presented in this study, the soft cervical collar did not adequately immobilize the cervical spine.

Does cervical kyphosis relate to symptoms following whiplash injury?

The mechanisms for developing long-lasting neck pain after whiplash injuries are still largely unrevealed. In the present study it was investigated whether a kyphotic deformity of the cervical spine, as opposed to a straight or a lordotic spine, was associated with the symptoms at baseline, and with the prognosis one year following a whiplash injury. MRI was performed in 171 subjects about 10 d after the accident, and 104 participated in the pain recording at 1-year follow-up. It was demonstrated that postures as seen on MRI can be reliably categorized and that a straight spine is the most frequent appearance of the cervical spine in supine MRI. In relation to symptoms it was seen that a kyphotic deformity was associated with reporting the highest intensities of headache at baseline, but not with an increased risk of long-lasting neck pain or headache. In conclusion, a kyphotic deformity is not significantly associated with chronic whiplash associated pain. Moreover, it is a clear clinical implication that pain should not be ascribed to a straight spine on MRI. We suggest that future trials on cervical posture focus upon the presence of kyphotic deformity rather than just on the absence of lordosis.

A research synthesis of therapeutic interventions for whiplash-associated disorder: part 1 - overview and summary

Whiplash-associated disorder (WAD) represents a significant public health problem, resulting in a substantial socioeconomic burden throughout the industrialized world, wherever costs are documented. While many treatments have been advocated for patients with WAD, scientific evidence of their effectiveness is often lacking. A systematic review was conducted to evaluate the strength of evidence supporting various WAD therapies. Multiple databases (including Web of Science, EMBASE and PubMed) were searched to identify all studies published from January 1980 through March 2009 that evaluated the effectiveness of any clearly defined treatment for acute (less than two weeks), subacute (two to 12 weeks) or chronic (longer than 12 weeks) WAD. The present article, the first in a five-part series, provides an overview of the review methodology as well as a summary and discussion of the review's main findings. Eighty-three studies met the inclusion criteria, 40 of which were randomized controlled trials. The majority of studies (n=47) evaluated treatments initiated in the chronic stage of the disorder, while 23 evaluated treatments for acute WAD and 13 assessed therapies for subacute WAD. Exercise and mobilization programs for acute and chronic WAD had the strongest supporting evidence, although many questions remain regarding the relative effectiveness of various protocols. At present, there is insufficient evidence to support any treatment for subacute WAD. For patients with chronic WAD who do not respond to conventional treatments, it appears that radiofrequency neurotomy may be the most effective treatment option. The present review found a relatively weak but growing research base on which one could make recommendations for patients at any stage of the WAD continuum. Further research is needed to determine which treatments are most effective at reducing the disabling symptoms associated with WAD.

A research synthesis of therapeutic interventions for whiplash-associated disorder (WAD): part 2 - interventions for acute WAD

Whiplash-associated disorder (WAD) represents a significant public health problem, resulting in substantial social and economic costs throughout the industrialized world. While many treatments have been advocated for patients with WAD, scientific evidence supporting their effectiveness is often lacking. A systematic review was conducted to evaluate the strength of evidence associated with various WAD therapies. Multiple databases (including Web of Science, EMBASE and PubMed) were searched to identify all studies published from January 1980 through March 2009 that evaluated the effectiveness of any clearly defined treatment for acute (less than two weeks), subacute (two to 12 weeks) or chronic (more than 12 weeks) WAD. The present article, the second in a five-part series, evaluates the evidence for interventions initiated during the acute phase of WAD. Twenty-three studies that met the inclusion criteria were identified, 16 of which were randomized controlled trials with 'fair' overall methodological quality (median Physiotherapy Evidence Database score of 5.5). For the treatment of acute WAD, there was strong evidence to suggest that not only is immobilization with a soft collar ineffective, but it may actually impede recovery. Conversely, although exercise programs, active mobilization and advice to act as usual all appeared to improve recovery, it is not clear which of these interventions was the most effective. While there was also evidence supporting the use of pulsed electromagnetic field therapy and methylprednisolone infusion, the evidence was insufficient to establish the effectiveness of either of these treatments. Based on current evidence, activation-based therapy is recommended for the treatment of acute WAD; however, additional research is required to determine the relative effectiveness of various exercise⁄mobilization programs.

Screening for head, neck, and shoulder pathology in patients with upper extremity signs and symptoms

NARRATIVE REVIEW: Conditions of the head, neck, thorax, and shoulder may occur simultaneously with arm pathology or produce symptoms perceived by the patient to originate in the elbow, wrist, or hand. Identification of the tissue disorder and associated impairments, followed by matching the rehabilitative intervention to address these issues, leads to optimal outcomes. With this goal in mind, the hand therapist needs to recognize clinical findings that signal potentially serious medical conditions of the brain, cervical region, chest, or shoulder. Additionally, less serious but potentially debilitating, musculoskeletal or neurogenic pain from proximal sources must also be differentiated from somatic pain originating in the elbow, wrist, or hand so that the clinician can decide to further examine and intervene or refer to an appropriate health care provider. This article describes clinical findings that suggest the presence of serious medical pathology in the head, neck, or thorax and presents a screening algorithm to assist in discriminating pain derived from local structures in the distal arm from referred pain originating in the more proximal regions of the shoulder, thorax, neck, or brain.

What factors have influence on persistence of neck pain after a whiplash?

STUDY DESIGN

Prospective longitudinal study.

OBJECTIVE

To identify prognosis factors that allow us to identify patients with risk of developing chronic symptoms and disabilities after a whiplash injury.

SUMMARY OF BACKGROUND DATA

The prognosis factors for poor recovery in acute whiplash are not conclusive.

METHODS

We included 557 patients who suffered whiplash injury after road traffic accident and visited the Department of Physical Medicine and Rehabilitation of Mataró Hospital (Spain) for medical evaluation and rehabilitation treatment. The variables were collected following a protocol designed for the study, and all patients were assessed through the Visual Analogue Scale (VAS) for the intensity of neck pain, the Goldberg Depression and Anxiety Scale and the Northwick Park Neck Pain Questionnaire (NPH) for cervical column functionality at initial evaluation and 6 months later.

RESULTS

Factors related with VAS 6 months after the whiplash injury were women, age, number of days of cervical column immobilization, previous neck pain, self-employed workers, housewives, pensioners, students, presence of headache or dizziness, and VAS, Goldberg Depression and Anxiety scale, and NPH scores at initial evaluation. In multivaried analysis, it had been found that the variables that had influence on VAS 6 months after the whiplash injury were statistically significant for age, presence of dizziness, self-employed workers, and VAS and NPH scores at initial evaluation.

CONCLUSION

Our findings indicate that factors that allow us to identify patients at risk for poor recovery are age, dizziness, and initial evaluation of neck pain with VAS and cervical column functionality with NPH.

Adverse events associated with the use of cervical manipulation and mobilization for the treatment of neck pain in adults: a systematic review

Adverse events (AE) are a concern for practitioners utilizing cervical manipulation or mobilization. While efficacious, these techniques are associated with rare but serious adverse events. Five bibliographic databases (PubMed, CINAHL, PEDro, AMED, EMBASE) and the gray literature were searched from 1998 to 2009 for any AE associated with cervical manipulation or mobilization for neck pain. Randomized controlled trials (RCTs), prospective or cross-sectional observational studies were included. Two independent reviewers conducted study selection, method quality assessment and data abstraction. Pooled relative risks (RR) were calculated. Study quality was assessed using the Cochrane system, a modified Critical Appraisal Skills Program form and the McHarm scale to assess the reporting of harms. Seventeen of 76 identified citations resulted in no major AE. Two pooled estimates for minor AE found transient neurological symptoms [RR 1.96 (95% CI: 1.09-3.54) p < 0.05]; and increased neck pain [RR 1.23 (95% CI: 0.85-1.77) p > .05]. Forty-four studies (58%) were excluded for not reporting AE. No definitive conclusions can be made due to a small number of studies, weak association, moderate study quality, and notable ascertainment bias. Improved reporting of AE in manual therapy trials as recommended by the CONSORT statement extension on harms reporting is warranted.

Manipulation or mobilisation for neck pain

BACKGROUND

Manipulation and mobilisation are often used, either alone or combined with other treatment approaches, to treat neck pain.

OBJECTIVES

To assess if manipulation or mobilisation improves pain, function/disability, patient satisfaction, quality of life, and global perceived effect in adults with acute/subacute/chronic neck pain with or without cervicogenic headache or radicular findings.

SEARCH STRATEGY

CENTRAL (The Cochrane Library 2009, issue 3) and MEDLINE, EMBASE, Manual Alternative and Natural Therapy, CINAHL, and Index to Chiropractic Literature were updated to July 2009.

SELECTION CRITERIA

Randomised controlled trials on manipulation or mobilisation.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies, abstracted data, and assessed risk of bias. Pooled relative risk and standardised mean differences (SMD) were calculated.

MAIN RESULTS

We included 27 trials (1522 participants).Cervical Manipulation for subacute/chronic neck pain : Moderate quality evidence suggested manipulation and mobilisation produced similar effects on pain, function and patient satisfaction at intermediate-term follow-up. Low quality evidence showed manipulation alone compared to a control may provide short- term relief following one to four sessions (SMD pooled -0.90 (95%CI: -1.78 to -0.02)) and that nine or 12 sessions were superior to three for pain and disability in cervicogenic headache. Optimal technique and dose need to be determined.Thoracic Manipulation for acute/chronic neck pain : Low quality evidence supported thoracic manipulation as an additional therapy for pain reduction (NNT 7; 46.6% treatment advantage) and increased function (NNT 5; 40.6% treatment advantage) in acute pain and favoured a single session of thoracic manipulation for immediate pain reduction compared to placebo for chronic neck pain (NNT 5, 29% treatment advantage).Mobilisation for subacute/chronic neck pain: In addition to the evidence noted above, low quality evidence for subacute and chronic neck pain indicated that 1) a combination of Maitland mobilisation techniques was similar to acupuncture for immediate pain relief and increased function; 2) there was no difference between mobilisation and acupuncture as additional treatments for immediate pain relief and improved function; and 3) neural dynamic mobilisations may produce clinically important reduction of pain immediately post-treatment. Certain mobilisation techniques were superior.

AUTHORS' CONCLUSIONS

Cervical manipulation and mobilisation produced similar changes. Either may provide immediate- or short-term change; no long-term data are available. Thoracic manipulation may improve pain and function. Optimal techniques and dose are unresolved. Further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate.

A Cochrane review of patient education for neck pain

BACKGROUND CONTEXT

Neck pain is common, disabling, and costly. The effectiveness of patient education strategies is unclear.

PURPOSE

To assess whether patient education strategies are of benefit for pain, function/disability, global perceived effect, quality of life, or patient satisfaction, in adults with neck pain with or without radiculopathy.

STUDY DESIGN

Cochrane systematic review.

METHODS

Computerized bibliographic databases were searched from their start to May 31, 2008. Eligible studies were randomized trials investigating the effectiveness of patient education strategies for neck pain. Paired independent reviewers carried out study selection, data abstraction, and methodological quality assessment. Relative risk and standardized mean differences were calculated. Because of differences in intervention type or disorder, no studies were considered appropriate to pool.

RESULTS

Of the 10 selected trials, two (20%) were rated as of high quality. Patient education was assessed as follows: 1) eight trials of advice focusing on activation compared with no treatment, or to various active treatments, including therapeutic exercise, manual therapy, and cognitive behavioral therapy, showed either inferiority or no difference for pain, spanning a full range of follow-up periods, acuity and disorder types. When compared with rest, two trials that assessed acute whiplash-associated disorder showed moderate evidence of no difference for advice focusing on activation; 2) two trials studying advice focusing on pain and stress coping skills found moderate evidence of no benefit for chronic neck pain at intermediate- to long-term follow-up; and 3) one trial compared the effects of neck school to no treatment, yielding limited evidence of no benefit for pain, at intermediate-term follow-up in mixed acute/subacute/chronic neck pain.

CONCLUSIONS

This review has not shown effectiveness for educational interventions for neck pain of various acuity stages and disorder types and at various follow-up periods, including advice to activate, advice on stress coping skills, and neck school. In future research, further attention to methodological quality is necessary. Studies of multimodal interventions should consider study designs, such as factorial designs, that permit discrimination of specific educational components.

Identifying the best treatment among common nonsurgical neck pain treatments: a decision analysis

STUDY DESIGN

Decision analysis.

OBJECTIVE

To identify the best treatment for nonspecific neck pain.

SUMMARY OF BACKGROUND DATA

In Canada and the United States, the most commonly prescribed neck pain treatments are nonsteroidal anti-inflammatory drugs (NSAIDs), exercise, and manual therapy. Deciding which treatment is best is difficult because of the trade-offs between beneficial and harmful effects, and because of the uncertainty of these effects.

METHODS

(Quality-adjusted) life expectancy associated with standard NSAIDs, Cox-2 NSAIDs, exercise, mobilization, and manipulation were compared in a decisionanalytic model. Estimates of the course of neck pain, background risk of adverse events in the general population, treatment effectiveness and risk, and patient-preferences were input into the model. Assuming equal effectiveness, we conducted a baseline analysis using risk of harm only. We assessed the stability of the baseline results by conducting a second analysis that incorporated effectiveness data from a high-quality randomized trial.

RESULTS

There were no important differences across treatments. The difference between the highest and lowest ranked treatments predicted by the baseline model was 4.5 days of life expectancy and 3.4 quality-adjusted life-days. The difference between the highest and lowest ranked treatments predicted by the second model was 7.3 quality-adjusted life-days.

CONCLUSION

When the objective is to maximize life expectancy and quality-adjusted life expectancy, none of the treatments in our analysis were clearly superior.

The physical therapist as a musculoskeletal specialist in the emergency department

Because patients with musculoskeletal injuries commonly seek intervention in the emergency department (ED), it has been proposed that practitioners with expertise in musculoskeletal practice can be of benefit in this setting. This clinical commentary describes the rationale for utilizing physical therapists as musculoskeletal specialists in the ED. Evidence indicates that physical therapists have the knowledge and skills to provide such expertise. Literature describing ED practice suggests that the management of patients with musculoskeletal conditions would be improved through the consistent integration of evaluation and treatment principles associated with physical therapy practice. Furthermore, early access to physical therapy, as can be provided in the ED setting, has the potential to positively influence patient recovery. Based on prior research and recent evolution of practice, further consideration of physical therapists as consultants in the ED is warranted, and, therefore, additional dialogue on the subject should be encouraged.
