Reliability and validity of CODA motion analysis system for measuring cervical range of motion in patients with cervical spondylosis and anterior cervical fusion

Abstract

The aim of the present study was to evaluate the reliability of the Cartesian Optoelectronic Dynamic Anthropometer (CODA) motion system in measuring the cervical range of motion (ROM) and verify the construct validity of the CODA motion system. A total of 26 patients with cervical spondylosis and 22 patients with anterior cervical fusion were enrolled and the CODA motion analysis system was used to measure the three-dimensional cervical ROM. Intra- and inter-rater reliability was assessed by interclass correlation coefficients (ICCs), standard error of measurement (SEm), Limits of Agreements (LOA) and minimal detectable change (MDC). Independent samples t-tests were performed to examine the differences of cervical ROM between cervical spondylosis and anterior cervical fusion patients. The results revealed that in the cervical spondylosis group, the reliability was almost perfect (intra-rater reliability: ICC, 0.87–0.95; LOA, −12.86–13.70; SEm, 2.97–4.58; inter-rater reliability: ICC, 0.84–0.95; LOA, −13.09–13.48; SEm, 3.13–4.32). In the anterior cervical fusion group, the reliability was high (intra-rater reliability: ICC, 0.88–0.97; LOA, −10.65–11.08; SEm, 2.10–3.77; inter-rater reliability: ICC, 0.86–0.96; LOA, −10.91–13.66; SEm, 2.20–4.45). The cervical ROM in the cervical spondylosis group was significantly higher than that in the anterior cervical fusion group in all directions except for left rotation. In conclusion, the CODA motion analysis system is highly reliable in measuring cervical ROM and the construct validity was verified, as the system was sufficiently sensitive to distinguish between the cervical spondylosis and anterior cervical fusion groups based on their ROM.

Measurements of cervical range of motion using an optical motion capture system: Repeatability and validity

“…A variety of neck diseases, such as cervical spondylosis, directly cause limited cervical vertebrae mobility (6). The degree of cervical vertebral ROM reduction is associated with the severity of neck disease (26).…”

“…Cervical ROM is an indicator of cervical pain and a variety of cervical spine diseases (2). ROM can be used as an evaluation parameter to monitor the effect of cervical disease treatment, including when assessing clinical results after anterior decompression and cervical spine fusion (2,5,6). With ROM measurements, clinicians can adjust treatment plans according to cervical vertebral mobility changes (5).…”

“…Accurate cervical ROM measurements are important. However, due to the complex anatomy of the cervical spine and the coupled movement of the cervical and thoracic spine, it is currently challenging to obtain accurate cervical ROM measurements (6,7). Several methods are currently used to measure cervical vertebrae activity, including eye measurements (8,9), general protractor use (10), and cervical ROM (CROM) device (3,11,12), cervical laser (13), radiographic (14), computed tomographic (15) and tap measurements (10,16,17).…”

Validity and reliability of Veloflex to measure active cervical range of motion in asymptomatic and symptomatic subjects

“…There are a wide variety of methods to evaluate CROM, ranging from more traditional methods (simple visual estimation, inclinometers, or goniometers) ( Youdas, Carey & Garrett, 1991 ; Audette et al, 2010 ) to more recent devices such as smartphone applications ( Tousignant-Laflamme et al, 2013 ; Quek et al, 2014 ; Pourahmadi et al, 2018 ; Stenneberg et al, 2018 ; Rodríguez-Sanz et al, 2018 ) or optoelectronic devices ( Zhongyang et al, 2017 ; Feng et al, 2019 ). A recent systematic review of reliability and validity studies of CROM measurement methods concluded that the CROM device (composed of three inclinometers) was shown to be clinimetrically sound ( Williams et al, 2010 ).…”
