Craniocervical chiropractic procedures - a précis of upper cervical chiropractic.

Presented here is a narrative review of upper cervical procedures intended to facilitate understanding and to increase knowledge of upper cervical chiropractic care. Safety, efficacy, common misconceptions, and research are discussed, allowing practitioners, chiropractic students, and the general public to make informed decisions regarding utilization and referrals for this distinctive type of chiropractic care. Upper cervical techniques share the same theoretical paradigm in that the primary subluxation exists in the upper cervical spine. These procedures use similar assessments to determine if spinal intervention is necessary and successful once delivered. The major difference involves their use of either an articular or orthogonal radiograph analysis model when determining the presence of a misalignment. Adverse events following an upper cervical adjustment consist of mild symptomatic reactions of short-duration (< 24-hours). Due to a lack of quality and indexed references, information contained herein is limited by the significance of literature cited, which included non-indexed and/or non-peer reviewed sources.

Examen narratif de procédures de la cervicale supérieure afin de faciliter la compréhension et d'améliorer la connaissance des soins chiropratiques des cervicales supérieures. L'innocuité, l'efficacité, les méconnaissances courantes et la recherche font l'objet de discussion, ce qui permet aux praticiens, aux étudiants en chiropratique, et au public de prendre des décisions éclairées concernant l'utilisation et les recommandations pour ce type particulier de soins chiropratiques.Les techniques de la cervicale supérieure ont le même paradigme théorique, car les subluxations primaires existent dans la colonne cervicale supérieure. Ces procédures ont recours à des évaluations semblables pour déterminer si une intervention vertébrale est nécessaire et si elle est réussie une fois effectuée. La différence principale concerne l'utilisation soit d'une analyse radiographique articulaire ou orthogonale au moment de déterminer la présence d'un désalignement. Des évènements indésirables à la suite d'un ajustement de la cervicale supérieure consistent en des réactions symptomatiques légères de courte durée (< 24 heures).Étant donné le manque de références indexées et de qualité, les renseignements contenus aux présentes sont limités par l'importance des documents cités, qui comprennent des sources non indexées ou non révisées par des pairs.

Effect of Atlas Vertebrae Realignment in Subjects with Migraine: An Observational Pilot Study.

Introduction. In a migraine case study, headache symptoms significantly decreased with an accompanying increase in intracranial compliance index following atlas vertebrae realignment. This observational pilot study followed eleven neurologist diagnosed migraine subjects to determine if the case findings were repeatable at baseline, week four, and week eight, following a National Upper Cervical Chiropractic Association intervention. Secondary outcomes consisted of migraine-specific quality of life measures. Methods. After examination by a neurologist, volunteers signed consent forms and completed baseline migraine-specific outcomes. Presence of atlas misalignment allowed study inclusion, permitting baseline MRI data collection. Chiropractic care continued for eight weeks. Postintervention reimaging occurred at week four and week eight concomitant with migraine-specific outcomes measurement. Results. Five of eleven subjects exhibited an increase in the primary outcome, intracranial compliance; however, mean overall change showed no statistical significance. End of study mean changes in migraine-specific outcome assessments, the secondary outcome, revealed clinically significant improvement in symptoms with a decrease in headache days. Discussion. The lack of robust increase in compliance may be understood by the logarithmic and dynamic nature of intracranial hemodynamic and hydrodynamic flow, allowing individual components comprising compliance to change while overall it did not. Study results suggest that the atlas realignment intervention may be associated with a reduction in migraine frequency and marked improvement in quality of life yielding significant reduction in headache-related disability as observed in this cohort. Future study with controls is necessary, however, to confirm these findings. Clinicaltrials.gov registration number is NCT01980927.

Interexaminer reliability of supine leg checks for discriminating leg-length inequality.

OBJECTIVE: The purpose of this study was to quantify interexaminer reliability of a standardized supine leg check procedure used to screen for leg-length inequality. METHODS: Two doctors of chiropractic used a standardized supine leg check procedure to examine 50 volunteers for leg-length inequality. The order of examination was randomized. The side and magnitude of leg-length inequality were determined to the nearest 1/8 in. Subjects and examiners were blinded. Interexaminer reliability was assessed with a Bland-Altman plot, tolerance table of absolute differences, a quadratic weighted κ statistic for quantitative scores, and a Gwet's first-order agreement coefficient for dichotomous ratings. RESULTS: The quadratic weighted κ statistic to quantify the reliability of the rating scale was 0.44 (95% confidence interval, 0.21-0.67), indicating moderate reliability. The 2 examiners agreed exactly 32% of the time, within 1/8 in 58% of the time, within 3/16 in 72% of the time, and within 3/8 in 92% of the time. The Bland-Altman plot revealed possible heterogeneity in reliability that requires additional study. The examiners agreed on the presence of a leg-length inequality of at least 1/8 in in 40 (80%) of 50 subjects (first-order agreement coefficient, 0.76), suggesting good agreement for this diagnostic category. CONCLUSION: The examiners showed moderate reliability in assessing leg-length inequality at 1/8-in increments and good reliability in determining the presence of a leg-length inequality.
