Reliability and validity of clinical tests to assess the anatomical integrity of the cervical spine in adults with neck pain and its associated disorders: Part 1-A systematic review from the Cervical Assessment and Diagnosis Research Evaluation (CADRE) Collaboration

Agreement and concurrent validity between telehealth and in-person diagnosis of musculoskeletal conditions: a systematic review

OBJECTIVES

To assess the concurrent validity and inter-rater agreement of the diagnosis of musculoskeletal (MSK) conditions using synchronous telehealth compared to standard in-person clinical diagnosis.

METHODS

We searched five electronic databases for cross-sectional studies published in English in peer-reviewed journals from inception to 28 September 2023. We included studies of participants presenting to a healthcare provider with an undiagnosed MSK complaint. Eligible studies were critically appraised using the QUADAS-2 and QAREL criteria. Studies rated as overall low risk of bias were synthesized descriptively following best-evidence synthesis principles.

RESULTS

We retrieved 6835 records and 16 full-text articles. Nine studies and 321 patients were included. Participants had MSK conditions involving the shoulder, elbow, low back, knee, lower limb, ankle, and multiple conditions. Comparing telehealth versus in-person clinical assessments, inter-rater agreement ranged from 40.7% agreement for people with shoulder pain to 100% agreement for people with lower limb MSK disorders. Concurrent validity ranged from 36% agreement for people with elbow pain to 95.1% agreement for people with lower limb MSK conditions.

DISCUSSION

In cases when access to in-person care is constrained, our study implies that telehealth might be a feasible approach for the diagnosis of MSK conditions. These conclusions are based on small cross-sectional studies carried out by similar research teams with similar participant demographics. Additional research is required to improve the diagnostic precision of telehealth evaluations across a larger range of patient groups, MSK conditions, and diagnostic accuracy statistics.

Inter- and intra-rater-reliability of a clinical framework for spine-related neck-arm pain

OBJECTIVE

A mechanism-based clinical framework for spine-related pain differentiates (i) somatic referred pain, ii) heightened nerve mechanosensitivity, iii) radicular pain, iv) radiculopathy and mixed-pain. This study aimed to determine the reliability of proposed framework.

METHOD

Fifty-one people with unilateral spine-related neck-arm pain were assessed and categorized by examiner-1. The classifications were compared to those made by two other examiners, based on written documentation of examiner-1. Cohens kappa was calculated between examiner-pairs; Fleiss Kappa among all examiners to assess agreement in classifying subgroups and entire framework.

RESULT

Inter-rater-reliability showed moderate to almost perfect reliability (somatic: no variation, mechanosensitivity: 0.96 (95% CI 0.87-1.0) to 1.0 (95% CI: 1.0-1.0), radicular pain: 0.46 (95% CI: 0.19-0.69) to 0.62 (95% CI: 0.42-0.81), radiculopathy: 0.65 (95% CI: 0.43-0.84) to 0.80 (95% CI: 0.63-0.96) mixed-pain: 0.54 (95% CI: 0.21-0.81) to 0.75 (95% CI: 0.48-0.94). There was almost perfect to moderate reliability among all examiners (somatic: no variation, mechanosensitivity: 0.97 (95% CI: 0.82-1.0), radicular pain: 0.56 (95% CI: 0.40-0.71), radiculopathy: 0.74 (95% CI: 0.58-0.90), mixed-pain: 0.63 (95% CI: 0.47-0.79), entire framework: 0.64 (95% CI: 0.57-0.71)). Intra-rater-reliability showed substantial to almost perfect reliability (somatic: no variation, mechanosensitivity: 0.96 (95% CI: 0.87-1.0), radicular pain: 0.76 (95% CI: 0.57-0.92), radiculopathy: 0.84 (95% CI: 0.67-0.96), mixed-pain: 0.83 (95% CI: 0.60-1.0), entire framework: 0.80 (95% CI: 0.61-0.92).

CONCLUSION

Moderate to almost perfect reliability in subgrouping people with spine-related neck-arm pain and substantial reliability for entire framework support this classification's reliability.

Eligibility Criteria of Participants in Randomized Controlled Trials Assessing Conservative Management of Cervical Radiculopathy: A Systematic Review

STUDY DESIGN

Systematic review.

OBJECTIVE

The aim of this study was to evaluate the inclusion and exclusion criteria for participants in randomized control trials (RCTs) assessing conservative management for cervical radiculopathy (CR), to determine if any consensus exists within the literature.

SUMMARY OF BACKGROUND DATA

A 2012 systematic review identified a lack of uniformity for the eligibility criteria of participants in RCTs evaluating conservative interventions for CR. Since then, a large number of RCTs have been published, signaling the need for an updated evaluation of this topic.

MATERIALS AND METHODS

We electronically searched MEDLINE, CENTRAL, CINAHL, Embase, and PsycINFO from inception to June 15, 2022, to identify RCTs assessing conservative management of CR. Information extracted was analyzed to determine the level of homogeneity and/or heterogeneity of the inclusion and exclusion criteria across studies.

RESULTS

Seventy-six RCTs met our inclusion criteria with 68 distinct trials identified. The inclusion of arm pain with or without another symptom ( i.e. numbness, paresthesia, or weakness) was required in 69.12% of trials, 50% of trials required participants to exhibit neck symptoms, and 73.53% of studies required some form of clinical examination findings, but inconsistencies existed for the number and type of tests used. Furthermore, 41.18% of trials included imaging, with 33.82% of trials requiring magnetic resonance imaging findings. The most common exclusion criteria included were the presence of red flags and cervical myelopathy in 66.18% and 58.82% of trials, respectively.

CONCLUSIONS

Overall, there is still a lack of uniformity for the inclusion/exclusion criteria of trials assessing the conservative management of CR, with some improvements noted compared with the 2012 review. Based on the current literature assessing the diagnostic utility of clinical symptoms and confirmatory tests, we proposed inclusion criteria for trials assessing conservative interventions. Future research should aim to develop standardized classification criteria to improve consistency among studies.

A guide to identify cervical autonomic dysfunctions (and associated conditions) in patients with musculoskeletal disorders in physical therapy practice

BACKGROUND

Differential diagnosis is a hot topic in physical therapy, especially for those working in a direct access setting dealing with neck pain and its associated disorders. All international guidelines agree in recommending to first rule out non-musculoskeletal pathologies as the cause of signs and symptoms in the patient. Although the autonomic nervous system (ANS) has a crucial role and is also involved in pain conditions, coverage of it in neuroscience textbooks and educational programmes is limited and most healthcare professionals are unfamiliar with it. Although autonomic conditions are benign in nature, they are clinically of great importance as they may be a 'red flag' warning of an injury along the sympathetic pathway. Therefore, sound knowledge of the ANS system is essential for clinicians.

OBJECTIVE

To develop physical therapists' knowledge of and confidence in understanding cervical ANS function and dysfunction, thus enhancing clinical reasoning skills and the pattern recognition process, and performing and interpreting objective examinations.

METHODS

This master class provides an introductory guide and essential knowledge to facilitate clinicians to understand cervical autonomic dysfunctions and their clinical evaluation. The optimal referral method is also handled.

CONCLUSIONS

Gaining knowledge and understanding of the ANS, its function, its dysfunction, and the related clinical manifestations is likely to lead to a decision-making process driven by 'science and conscience'. This will empower physical therapists to be aware of subtle clues that may be offered by patients during the interview and history intake leading to the appropriate physical examination and triage.

Neurological outcomes after surgery and postoperative rehabilitation for cervical radiculopathy due to disc disease: a 2-year-follow-up of a randomized clinical trial

Reports on neurological outcomes in patients with cervical radiculopathy (CR) undergoing surgery and postoperative rehabilitation are important to inform prognosis. This 2-year-follow-up of a randomized clinical trial aimed to compare secondary neurological outcomes between structured postoperative rehabilitation and a standard approach after surgery for CR. A secondary aim was to increase knowledge about recovery of neurological impairments in relation to patient-reported neck disability. Neurological outcomes included assessment of sensibility, motor function, arm reflexes and the Spurling test. A total of 153 and 135 participants (> 70% response rate) completed the clinical examination. Between-group differences, changes over time, and associations between persistent neurological impairments and the Neck Disability Index were investigated. No between-group differences were reported (p > 0.07), and neurological impairments in sensibility, motor function, and a positive Spurling test decreased over time in both groups (p < 0.04). Persistent impairments in sensibility and reflex arm were most frequent at follow-up, whereas, a persistent positive Spurling test, and impairments in motor function were associated with higher NDI score. Neurological outcomes improved over time in patients undergoing surgery for CR with no between-group differences., However, persistent neurological impairments were common, and associated with poorer outcome for patient-reported neck disability.Clinical registration: clinicaltrial.gov NCT01547611, 08/03/2012, Title: Outcome of physiotherapy after surgery for cervical disc disease: a prospective multi-centre trial.

Do chiropractic interns use clinical practice guidelines when managing patients with neck pain in France? A feasibility study

BACKGROUND

In France, we lack knowledge about factors influencing chiropractors' use of French guideline for managing neck pain and associated disorders (NAD). In particular, we know little about how chiropractic interns use clinical practice guidelines during their training.

OBJECTIVES

We aimed to determine the feasibility of conducting a cross-sectional study of chiropractic interns to determine their utilization and conformity with clinical practice guidelines when managing patients with NAD in France.

METHOD

We developed a web-based questionnaire which included 3 sections: (1) clinical vignettes; (2) determinants of practice and (3) socio-demographic and current practice information. The study was conducted in two phases. The first phase included 2 groups: chiropractors and students (interns). Ten chiropractors reviewed and made recommendations on content (especially clinical vignettes), readability, and flow of the survey. Fifteen interns were invited to pretest the proposed recruitment strategy and determine time needed to survey completion, assess completeness of data collection, and evaluate its readability and flow in students. Due to the low participation of students during the first phase, 20 additional interns were invited to participate and pilot the revised recruitment strategy during the second phase. A group of 20 interns were invited to participate and pilot the revised recruitment strategy during the second phase. Qualitative feedbacks about the recruitment strategy, the content of the questionnaire and the survey process were collected by phone to improve all these steps if necessary.

RESULTS

We collected data from November 2020 to February 2021. In phase 1, 70% of chiropractors (7/10) reviewed the survey and one intern responded (7% participation rate). A revised recruitment strategy was designed and 70% of interns agreed to participate in phase 2. Time to complete the questionnaire was on average 48 m:22 s. Interns evaluated survey content as relevant, comprehensive, covering the range of 4 grades of NAD, and adapted to an intern sample. Five main modifications were recommended by (1) Adjusting survey support; (2) Enhancing communication strategy; (3) Considering interns' comments about the length of the questionnaire; (4) Modifying 2 determinants not adapted to a French context; (5) Adding a proposal when determinants deal with multidisciplinary management.

CONCLUSION

Conducting a web-based cross-sectional study of chiropractic interns to assess their utilization and conformity to clinical practice guideline is feasible.

Results

Conclusions

Characteristics, expectations, experiences of care, and satisfaction of patients receiving chiropractic care in a French University Hospital in Toulouse (France) over one year: a case study

BACKGROUND

In October 2017, a partnership was established between the University Hospital of Toulouse and the French Chiropractic College, "Institut Franco-Européen de Chiropraxie" (IFEC). Before 2017, chiropractors did not practice in hospitals in France. Chiropractic students and chiropractors are now integrated in an interdisciplinary medical team at University Hospital. Our study aimed to describe the characteristics of patients who received chiropractic care at the University Hospital of Toulouse, their expectations, experiences of care, and satisfaction.

METHOD

A prospective case study was conducted. Patients referred for chiropractic care in the French University Hospital of Toulouse from January to December 2020 were eligible to participate. Participants provided the following data: demographics, previous chiropractic care treatments, pain location, intensity (NRS) and duration, disability (NDI, ODI), health-related quality of life (SF-12) and depressive symptomatology (PHQ-9). We conducted semi-structured interviews to explore their expectations, barriers and facilitators impacting their experience of care, and satisfaction.

RESULTS

Seventeen participants were recruited and seven were interviewed. All participants had chronic pain with a median pain intensity of 05/10 (IQR 04-06) on the NRS scale. Nine of 17 participants presented with multiple pain locations. Thirteen of seventeen participants presented with low back pain and eight with neck pain. The median SF-12 health-related quality of life score was 50/100 (IQR 28.5-60.5) for physical health, and 52/100 (IQR 43-62) for mental health. The PHQ-9 median score of depressive symptomatology was 7.7/27 (IQR 2.0-12.5). Overall, participants were satisfied with their care and the collaboration between chiropractors and physicians. Participants expected a caring communication with the chiropractic team. Their experience was facilitated by their trust in their physician. Patients perceived the turnover of chiropractic students as a barrier to their satisfaction.

CONCLUSION

Our participants presented with chronic musculoskeletal pain and depressive symptoms. Our study identified facilitators and barriers for patient expectation and satisfaction with chiropractic care in a hospital setting. This study provides the first data describing the collaboration between chiropractors and physicians in France in the management of musculoskeletal disorders. These findings will inform the quality improvement of our partnership, student's training and the development of future hospital-based collaborations integrating chiropractic care in a multidisciplinary team in France.

Medial Branch Blocks for Diagnosis of Facet Joint Pain Etiology and Use in Chronic Pain Litigation

A commonly disputed medicolegal issue is the documentation of the location, degree, and anatomical source of an injured plaintiff’s ongoing pain, particularly when the painful region is in or near the spine, and when the symptoms have arisen as result of a relatively low speed traffic crash. The purpose of our paper is to provide health and legal practitioners with strategies to identify the source of cervical pain and to aid triers of fact (decision makers) in reaching better informed conclusions. We review the medical evidence for the applications and reliability of cervical medial branch nerve blocks as an indication of painful spinal facets. We also present legal precedents for the legal admissibility of the results of such diagnostic testing as evidence of chronic spine pain after a traffic crash. Part of the reason for the dispute is the subjective nature of pain, and the fact that medical documentation of pain complaints relies primarily on the history given by the patient. A condition that can be documented objectively is chronic cervical spine facet joint pain, as demonstrated by medial branch block (injection). The diagnostic accuracy of medial branch blocks has been extensively described in the scientific medical literature, and evidence of facet blocks to objectively document chronic post-traumatic neck pain has been accepted as scientifically reliable in courts and tribunals in the USA, Canada and the United Kingdom. We conclude that there is convincing scientific medical evidence that the results of cervical facet blocks provide reliable objective evidence of chronic post-traumatic spine pain, suitable for presentation to an adjudicative decision maker.

Diagnostic accuracy of patient interview items and clinical tests for cervical radiculopathy

OBJECTIVE

To determine the diagnostic accuracy of patient interview items and clinical tests to diagnose cervical radiculopathy.

DESIGN

A prospective diagnostic accuracy study.

PARTICIPANTS

Consecutive patients (N=134) with a suspicion of cervical radiculopathy were included. A medical specialist made the diagnosis of cervical radiculopathy based on the patient's clinical presentation and corresponding Magnetic Resonance Imaging findings. Participants completed a list of patient interview items and the clinical tests were performed by a physiotherapist.

MAIN OUTCOME MEASURES

Diagnostic accuracy was determined in terms of sensitivity, specificity, and positive (+LR) and negative likelihood ratios (-LR). Sensitivity and specificity values ≥0.80 were considered high. We considered +LR≥5 and -LR≤0.20 moderate, and +LR≥10 and -LR≤0.10 high.

RESULTS

The history items 'arm pain worse than neck pain', 'provocation of symptoms when ironing', 'reduction of symptoms by walking with your hand in your pocket', the Spurling test and the presence of reduced reflexes showed high specificity and are therefore useful to increase the probability of cervical radiculopathy when positive. The presence of 'paraesthesia' and 'paraesthesia and/or numbness' showed high sensitivity, indicating that the absence of these patient interview items decreases the probability of cervical radiculopathy. Although most of these items had potentially relevant likelihood ratios, none showed moderate or high likelihood ratios.

CONCLUSIONS

Several patient interview items, the Spurling test and reduced reflexes are useful to assist in the diagnosis of cervical radiculopathy. Because there is no gold standard for cervical radiculopathy, caution is required to not over-interpret diagnostic accuracy values.

Changes in Cervicocephalic Kinesthetic Sensibility, Widespread Pressure Pain Sensitivity, and Neck Pain After Cervical Thrust Manipulation in Patients With Chronic Mechanical Neck Pain: A Randomized Clinical Trial

OBJECTIVE

The purpose of the current randomized clinical trial was to examine the effects of cervical thrust manipulation or sham manipulation on cervicocephalic kinaesthetic sense, pain, pain-related disability, and pressure pain sensitivity in patients with mechanical neck pain.

METHODS

Fifty-four individuals with neck pain were randomly assigned to receive either a cervical manipulation (right or left) or a sham manipulation. Immediate outcomes included cervical kinesthetic sense as assessed by joint position sense error (JPSE) and pressure pain thresholds (PPTs). At 1 week, neck pain intensity (numerical pain rate scale) and neck pain-related disability (Neck Disability Index [NDI]) outcomes were also collected.

RESULTS

The mixed-model analysis of covariance revealed a significant group × time interaction in favor of the cervical thrust manipulation group for the JPSE on rotation and extension. There was also a significant interaction for changes in PPTs at C5 to C6 and tibialis anterior. At the 1-week follow-up, a significant interaction existed for neck-related disability but not for neck pain at rest, worst pain, or lowest pain experienced the preceding week.

CONCLUSIONS

Our results suggest that cervical spine thrust manipulation improves JPSE, PPT and NDI in participants with chronic mechanical neck pain. Furthermore, changes in JPSE and NDI were large and surpass published minimal detectable changes for these outcome measures. In addition, the effect sizes of PPTs were medium; however, only C5 to C6 zygapophyseal joint exceeded the minimal detectable change. In contrast, cervical thrust manipulation did not improve neck pain intensity at 1 week after the intervention.

Reliability and validity of self-reported questionnaires to measure pain and disability in adults with neck pain and its associated disorders: part 3-a systematic review from the CADRE Collaboration

PURPOSE

To determine the reliability and validity of self-reported questionnaires to measure pain and disability in adults with grades I-IV neck pain and its associated disorders (NAD).

METHODS

We updated the systematic review of the 2000-2010 Bone and Joint Decade Task Force on Neck Pain and its Associated Disorders and systematically searched databases from 2005 to 2017. Independent reviewers screened and critically appraised studies using standardized tools. Evidence from low-risk-of-bias studies was synthesized according to best evidence synthesis principles. Validity studies were ranked according to the Sackett and Haynes classification.

RESULTS

We screened 2823 articles, and 26 were eligible for critical appraisal; 18 were low risk of bias. Preliminary evidence suggests that the Neck Disability Index (original and short versions), Whiplash Disability Questionnaire, Neck Pain Driving Index, and ProFitMap-Neck may be valid and reliable to measure disability in patients with NAD. We found preliminary evidence for the validity and reliability of pain measurements including the Body Pain Diagram, Visual Analogue Scale, the Numeric Rating Scale and the Pain-DETECT Questionnaire.

CONCLUSION

The evidence supporting the validity and reliability of instruments used to measure pain and disability is preliminary. Further validity studies are needed to confirm the clinical utility of self-reported questionnaires to assess pain and disability in patients with NAD.

Reliability and validity of clinical tests to assess posture, pain location, and cervical spine mobility in adults with neck pain and its associated disorders: Part 4. A systematic review from the cervical assessment and diagnosis research evaluation (CADRE) collaboration

PURPOSE

To determine the reliability and validity of clinical tests to assess posture, pain location, and cervical spine mobility in adults with grades I-IV neck pain and associated disorders (NAD).

METHODS

We systematically searched electronic databases to update the systematic review of the Bone and Joint Decade 2000-2010 Task Force on Neck Pain and Its Associated Disorders. Eligible reliability and validity studies were critically appraised using modified versions of the QAREL and QUADAS-2 instruments, respectively. Evidence from low risk of bias studies were synthesized following best evidence synthesis principles.

RESULTS

We screened 14302 articles, critically appraised 46 studies, and found 32 low risk of bias articles (14 reliability and 18 validity studies). We found preliminary evidence of: 1) reliability of visual inspection, aided with devices (CROM and digital caliper) to assess head posture; 2) reliability and validity of soft tissue palpation to locate tender/trigger points in muscles; 3) reliability and validity of joint motion palpation to assess stiffness and pain provocation in combination; and 4) range of motion tests using visual estimation (in cervical extension only) or devices (digital caliper, goniometer, inclinometer) to assess cervical mobility.

CONCLUSIONS

We found little evidence to support the reliability and validity of clinical tests to assess head posture, pain location and cervical mobility in adults with NAD grades I-III. More advanced validity studies are needed to inform the clinical utility of tests used to evaluate patients with NAD.

Neck-specific exercise may reduce radiating pain and signs of neurological deficits in chronic whiplash - Analyses of a randomized clinical trial

Up to 90% of people with neurological deficits following a whiplash injury do not recover and cervical muscle dysfunction is common. The aim of this multicentre, randomized controlled trial was to examine whether two versions of neck-specific exercise or prescription of physical activity (PPA) can improve radiating arm pain and clinical signs that can be associated with neurological deficits in people with chronic whiplash associated disorders (WAD). Participants with chronic WAD, arm symptoms and signs associated with neurological deficits (n = 171) were randomized to: 12 weeks of neck-specific exercise without (NSE) or with a behavioural approach (NSEB), or PPA. Pain/bothersomeness frequency, six measures of arm pain/paraesthesia (VAS scales), and four clinical neurological tests were evaluated after 3 months. The NSE group reported the lowest frequency and lowest levels of arm pain, the highest proportion of participants with at least 50% pain reduction and the highest proportion of normal arm muscle force. The NSEB group reported increased normal tendon reflexes. No improvements were recorded for the PPA group. Neck-specific exercise may improve arm pain and decrease signs of neurological deficits, but the addition of a behavioural approach does not seem to be of additional benefit.

Responsiveness and minimal important change of the NeckPix© in subjects with chronic neck pain undergoing rehabilitation

PURPOSE

The NeckPix© is a simple and rapid means of measuring the beliefs of subjects with chronic neck pain concerning pain-related fears of a specific set of activities of daily living. The original version showed satisfactory psychometric properties. This observational study is aimed at evaluating its responsiveness and minimal important changes (MICs) in subjects with chronic neck pain.

METHODS

At the beginning, at the end of an 8-week rehabilitation programme as well as at the one-year follow-up, 153 subjects completed the NeckPix©. After the programme and at follow-up, subjects and physiotherapists also completed the global perceived effect (GPE) scale, which was divided to produce a dichotomous outcome. Responsiveness was calculated by distribution [effect size (ES); standardised response mean (SRM)] and anchor-based methods [receiver-operating characteristics (ROC) curves; correlations between change scores of the NeckPix© and GPEs]. ROC curves were also used to compute MICs.

RESULTS

The ES ranged from 0.95 to 1.26 and the SRM from 0.84 to 0.98 at post-treatment and follow-up based on subjects' and physiotherapists' perspective. The ROC analyses revealed AUCs of 0.89 and 0.97 at post-treatment and follow-up, respectively; MICs (sensitivity; specificity) were of 6 (0.82; 0.88) and 8 (0.80; 0.92) at post-treatment and of 8 (0.95; 0.90 based on subjects and 0.95; 0.92 based on physiotherapists perspective) at follow-up. The correlations between change scores of the NeckPix© and GPEs ranged from -0.69 to -0.82.

CONCLUSIONS

The NeckPix© was sensitive in detecting clinical changes in subjects with chronic neck pain undergoing rehabilitation. We recommend taking the MICs provided into account when assessing subjects' improvement or planning studies in this clinical context.

Reliability and validity of clinical tests to assess the anatomical integrity of the cervical spine in adults with neck pain and its associated disorders: Part 1-A systematic review from the Cervical Assessment and Diagnosis Research Evaluation (CADRE) Collaboration

OBJECTIVE

To determine the reliability and validity of clinical tests to assess the anatomical integrity of the cervical spine in adults with neck pain and its associated disorders.

METHODS

We updated the systematic review of the 2000-2010 Bone and Joint Decade Task Force on Neck Pain and its Associated Disorders. We also searched the literature to identify studies on the reliability and validity of Doppler velocimetry for the evaluation of cervical arteries. Two independent reviewers screened and critically appraised studies. We conducted a best evidence synthesis of low risk of bias studies and ranked the phases of investigations using the classification proposed by Sackett and Haynes.

RESULTS

We screened 9022 articles and critically appraised 8 studies; all 8 studies had low risk of bias (three reliability and five validity Phase II-III studies). Preliminary evidence suggests that the extension-rotation test may be reliable and has adequate validity to rule out pain arising from facet joints. The evidence suggests variable reliability and preliminary validity for the evaluation of cervical radiculopathy including neurological examination (manual motor testing, dermatomal sensory testing, deep tendon reflexes, and pathological reflex testing), Spurling's and the upper limb neurodynamic tests. No evidence was found for doppler velocimetry.

CONCLUSIONS

Little evidence exists to support the use of clinical tests to evaluate the anatomical integrity of the cervical spine in adults with neck pain and its associated disorders. We found preliminary evidence to support the use of the extension-rotation test, neurological examination, Spurling's and the upper limb neurodynamic tests.
