Between-week reliability of the cervical range of motion (CROM) device for upper cervical rotation.

ABSTRACT: Background: The Cervical Range of Motion (CROM) device is a valid and reliable clinical tool used to measure full cervical rotation, however, its reliability for measuring upper cervical rotation is unknown.Objectives: Assess between-week test-retest reliability of the CROM device in measuring upper cervical rotationMethod: Thirty students participated in this test-retest reliability study. The CROM device was used to measure left and right cervical rotation in both a seated neutral and fully flexed head-neck position. Interclass correlation coefficient (ICC) was calculated for all motions. Measurement error was determined using standard error of measurement (SEM) and minimal detectable change (MDC).Results: The CROM device demonstrated moderate to good reliability (ICCs 0.65-0.9) of full and upper cervical rotation. The SEMs and MDCs of this study are small and suggest that the chance of repeated measurement error was relatively minimal for the between-week trials.Conclusions: The CROM device is a reliable outcome tool for measuring upper cervical rotation. The clinical implications of these findings suggest that therapists can utilize the CROM device to more completely examine all planes of upper and full cervical mobility. It may also assist in identifying upper cervical ROM limitations associated with underlying cervical pathology or motion dysfunction.

Project description:BackgroundSeveral water-based sports (swimming, surfing and stand up paddle boarding) require adequate thoracic mobility (specifically rotation) in order to perform the appropriate activity requirements. The measurement of thoracic spine rotation is problematic for clinicians due to a lack of convenient and reliable measurement techniques. More recently, smartphones have been used to quantify movement in various joints in the body; however, there appears to be a paucity of research using smartphones to assess thoracic spine movement. Therefore, the aim of this study is to determine the reliability (intra and inter rater) and validity of the iPhone® app (Compass) when assessing thoracic spine rotation ROM in healthy individuals.MethodsA total of thirty participants were recruited for this study. Thoracic spine rotation ROM was measured using both the current clinical gold standard, a universal goniometer (UG) and the Smart Phone Compass app. Intra-rater and inter-rater reliability was determined with a Intraclass Correlation Coefficient (ICC) and associated 95% confidence intervals (CI). Validation of the Compass app in comparison to the UG was measured using Pearson's correlation coefficient and levels of agreement were identified with Bland-Altman plots and 95% limits of agreement.ResultsBoth the UG and Compass app measurements both had excellent reproducibility for intra-rater (ICC 0.94-0.98) and inter-rater reliability (ICC 0.72-0.89). However, the Compass app measurements had higher intra-rater reliability (ICC = 0.96 - 0.98; 95% CI [0.93-0.99]; vs. ICC = 0.94 - 0.98; 95% CI [0.88-0.99]) and inter-rater reliability (ICC = 0.87 - 0.89; 95% CI [0.74-0.95] vs. ICC = 0.72 - 0.82; 95% CI [0.21-0.94]). A strong and significant correlation was found between the UG and the Compass app, demonstrating good concurrent validity (r = 0.835, p < 0.001). Levels of agreement between the two devices were 24.8° (LoA -9.5°, +15.3°). The UG was found to consistently measure higher values than the compass app (mean difference 2.8°, P < 0.001).ConclusionThis study reveals that the iPhone® app (Compass) is a reliable tool for measuring thoracic spine rotation which produces greater reproducibility of measurements both within and between raters than a UG. As a significant positive correlation exists between the Compass app and UG, this supports the use of either device in clinical practice as a reliable and valid tool to measure thoracic rotation. Considering the levels of agreement are clinically unacceptable, the devices should not be used interchangeably for initial and follow up measurements.

Project description:A longitudinal study using biplane radiography to measure in vivo intervertebral range of motion (ROM) during dynamic flexion/extension, and rotation.To longitudinally compare intervertebral maximal ROM and midrange motion in asymptomatic control subjects and single-level arthrodesis patients.In vitro studies consistently report that adjacent segment maximal ROM increases superior and inferior to cervical arthrodesis. Previous in vivo results have been conflicting, indicating that maximal ROM may or may not increase superior and/or inferior to the arthrodesis. There are no previous reports of midrange motion in arthrodesis patients and similar-aged controls.Eight single-level (C5/C6) anterior arthrodesis patients (tested 7?±?1 months and 28?±?6 months postsurgery) and six asymptomatic control subjects (tested twice, 58?±?6 months apart) performed dynamic full ROM flexion/extension and axial rotation whereas biplane radiographs were collected at 30?images per second. A previously validated tracking process determined three-dimensional vertebral position from each pair of radiographs with submillimeter accuracy. The intervertebral maximal ROM and midrange motion in flexion/extension, rotation, lateral bending, and anterior-posterior translation were compared between test dates and between groups.Adjacent segment maximal ROM did not increase over time during flexion/extension, or rotation movements. Adjacent segment maximal rotational ROM was not significantly greater in arthrodesis patients than in corresponding motion segments of similar-aged controls. C4/C5 adjacent segment rotation during the midrange of head motion and maximal anterior-posterior translation were significantly greater in arthrodesis patients than in the corresponding motion segment in controls on the second test date.C5/C6 arthrodesis appears to significantly affect midrange, but not end-range, adjacent segment motions. The effects of arthrodesis on adjacent segment motion may be best evaluated by longitudinal studies that compare maximal and midrange adjacent segment motion to corresponding motion segments of similar-aged controls to determine if the adjacent segment motion is truly excessive.3.
