RESUMO
PURPOSE: Cervical spine meniscoids are intra-articular folds of synovial membrane that have been theorised to have potential clinical significance in neck pain. Recent anatomical and clinical research has re-visited the pathoanatomical capacity of these structures. The purpose of this review is to discuss cervical spine meniscoid morphology in light of recently published work, to provide an update on the plausible relevance of these structures to clinical practice. METHODS: Narrative review critically discussing basic science and clinical research regarding cervical spine meniscoids, with focus upon implications for clinical practice. RESULTS: Basic science research indicates that cervical spine meniscoids can be innervated and appear to vary in morphology in the presence of articular degeneration. In a clinical population, associations have been observed between cervical spine meniscoid morphology and presence of cervical spine symptoms. CONCLUSIONS: Recent studies regarding cervical spine meniscoid morphology provide further evidence of pathoanatomical capacity of these structures. Further research is required, however, in clinical populations to empirically investigate specific theorised mechanisms of cervical spine meniscoid involvement in neck pain.

Internationally, manual therapy has moved towards formalised guidelines for pre-manipulative screening of the cervical spine. A controversial aspect to emerge from this involves craniovertebral instability (CVI) testing. This study examined current practice, knowledge and attitudes of Australian physiotherapists regarding pre-manipulative testing for CVI. Members of Musculoskeletal Physiotherapy Australia were surveyed by formally validated questionnaire. Sub-group analysis was performed by post-graduate musculoskeletal qualification. The response rate was 37.8%. Respondents provided differing definitions of CVI; 46.5% describing loss of anatomical integrity and 24.9% a biomechanical problem. Over half indicated they rarely or never used stress tests for CVI screening. Of 42 published signs and symptoms associated with CVI, seven were identified by more than 50% of respondents. Of published disorders associated with CVI, four were considered worthy of testing by more than 30% of respondents. Support for inclusion of information on CVI in pre-manipulative guidelines was given by 87% of respondents. Recommendations for screening tests received less support, particularly among physiotherapists holding post-graduate musculoskeletal qualifications (p = 0.0002). These results indicate disagreement regarding the nature and presentation of CVI. Clinical testing is inconsistent, reflecting underlying confusion about CVI. Currently, there is not an appropriate level of knowledge or willingness to recommend guidelines for CVI screening.

CONTEXT: Indigenous Australians living in rural communities suffer from multiple musculoskeletal problems that significantly impair their activities of daily living. They commonly report physical disability and 'having learned to live with their pain'. A pilot, accredited musculoskeletal training program in the form of a sports massage course was designed and implemented in an attempt to address modifiable, commonly-presenting musculoskeletal conditions in this community. ISSUE: Sports massage was taught to 20 participant Aboriginal Health workers (AHWs) and community Elders at Durri Aboriginal Corporation, New South Wales, Australia. Sports massage was chosen as the vehicle for skills development because sport was widely valued in the community. The participants were taught a variety of theoretical and massage skills in the 2 week course using the informal 'round table' techniques developed by Booroongen Djugun College, NSW, Australia. The course was evaluated positively by participants. Because the course was developed according to community guidelines it had high cultural acceptability. LESSONS: Sports massage skills have been adapted for treatment of patients with chronic illness and stress within the community. Development of the course according to community needs was essential for acceptance, as was the active involvement of AHWs in all phases. For sustainability, such courses require appropriate funding.
RESUMO
A sustained natural apophyseal glide (SNAG) is a mobilization technique commonly used in the treatment of painful movement restrictions of the cervical spine. In the manual therapy literature, the biological basis and empirical efficacy of cervical SNAGs have received scant attention. In particular, an examination of their potential biological basis in order to stimulate informed discussion seems overdue. This paper discusses the likely biomechanical effects of both the accessory and physiological movement components of a unilateral cervical SNAG applied ipsilateral to the side of pain when treating painfully restricted cervical rotation. The use of flexion and extension SNAGS, and rotation SNAGS performed contralateral to the side of pain are not considered. Although a cervical SNAG may clinically be able to resolve painfully restricted cervical spine movement, it is difficult to explain biomechanically why a technique which first distracts (opens) and then compresses (closes) the zygapophyseal joint ipsilateral to the side of pain, and perhaps slightly distracts the uncovertebral cleft, would be superior to a technique which distracts the articular surfaces with both accessory and physiological movement components. Therefore, the reported clinical efficacy of cervical SNAGs cannot be explained purely on the basis of the resultant biomechanical effects in the cervical spine.

The Australian Physiotherapy Association's Clinical Guidelines for Pre-Manipulative Procedures for the Cervical Spine represent a positive step towards the goal of reducing the incidence of vertebrobasilar strokes following neck manipulation. Nevertheless, the predictive value of the guidelines is largely contingent upon the validity of the physical screening tests, particularly sustained end-range cervical rotation. The primary issue is the sensitivity of the tests for detecting patients with vertebral artery occlusion and vertebrobasilar insufficiency, and who are at high risk of experiencing significant forces during manipulation which could result in intimal dissection.
RESUMO
BACKGROUND: Neck manipulation occasionally causes stroke after trauma to the vertebral or internal carotid artery. Premanipulativ e tests involving cervical spine rotation or extension have been recommended to detect patients at risk of neurovascular ischemia. However, the effect of these procedures on extracranial blood flow is not well established, and their validity is thus controversial. OBJECTIVE: To determine the effect of premanipulative tests involving cervical spine rotation or extension on vertebral artery and internal carotid artery blood flow parameters. DESIGN: Two-group experimental study. SUBJECTS: Twenty subjects consisting of 16 patients treated with physiotherapy and four volunteers. METHODS: Subjects were tested with a recommended premanipulative protocol by both an independent physiotherapist and an investigator. One group consisted of 10 subjects with signs or symptoms indicative of neurovascular ischemia on premanipulative testing, with 10 subjects with no signs or symptoms indicative of neurovascular ischemia on premanipulative testing comprising the second group. Hemodynamic measurements for both vertebral and both internal carotid arteries were taken by use of duplex Doppler ultrasonography with color-flow imaging with the subjects in the following positions: neutral, end-range extension, 45 degrees contralateral rotation, end-range contralateral rotation, and combined end-range contralateral rotation/extension. RESULTS: The reliability of premanipulative testing was supported. Significant changes in flow velocity of the vertebral artery (and to a lesser extent of the internal carotid artery) were shown in end-range positions involving rotation and extension. No meaningful significant differences were found between the two groups. CONCLUSIONS: Screening procedures that use rotation and extension may be useful tests of the adequacy of collateral circulation. A larger study is needed to determine whether subjects testing positive significantly differ from those testing negative.
