“…In the reliability analysis, the results based on Cronbach coefficients indicated good internal consistency among the patients with OPLL, which was consistent with studies in Hong Kong and Taiwan (26,27). For the test-retest reliability analysis, except for the bladder function domain, the domains had good test-retest reliability, as indicated by Pearson's correlation.…”

Background: The surgical outcomes of individual patient with ossification of the posterior longitudinal ligament (OPLL) can vary depending on various patient-related factors. Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire (JOACMEQ) is a well-developed tool for outcome measurement and considers both disease-specific and general health aspects. This study aimed to investigate the reliability, validity, and responsiveness of the JOACMEQ in patients with OPLL in mainland China and to compare post-operative outcomes of OPLL patients between mainland China and Japan.Methods: This multicenter trial was performed between July 2009 and June 2019. The procedure for the JOACMEQ translation followed Beaton's guidelines. All patients enrolled were diagnosed with OPLL and had completed the JOACMEQ, the modified Japanese Orthopaedic Association (mJOA) scale, and the 36-Item Short Form Health Survey (SF-36) before and after surgery. The reliability (Cronbach's α and Pearson's correlation), construct validity (factor analysis), concurrent validity (Spearman's correlation with SF-36) and responsiveness (effect sizes) of JOACMEQ were evaluated. A mixed-model analytic approach was used to analyze differences in postoperative outcomes between the 2 countries.Results: Ninety-one patients from mainland China and ninety-one patients from Japan were recruited.JOACMEQ showed satisfactory internal consistency (Cronbach's α=0.75). In test-retest reliability evaluation, except for the bladder function domain, the JOACMEQ domains had good test-retest reliability (0.89-0.96).In factor analysis, most of the items (19/24) were well clustered. Regarding clinical validity, all 5 domains were found to have moderate correlations with the physical component summary (PCS) of

“…The demographic, anthropometric, and standing balance assessment data were collected for all the participants. Functional outcomes were evaluated in the CSM group by the lower extremity function of modified Japanese Orthopaedic Association Scale (mJOA-LEF) [32], the lower extremity function of Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire (Chinese version; JOACMEQ-LEF) [33–35], and the Nurick scale [36]. The mJOA-LEF and JOACMEQ-LEF were assessed to evaluate the functional performance, and the Nurick scale was assessed to evaluate the walking ability.…”

Background Cervical spondylotic myelopathy (CSM) is a degenerative cervical disease in which the spinal cord is compressed. Patients with CSM experience balance disturbance because of impaired proprioception. The weighting of the sensory inputs for postural control in patients with CSM is unclear. Therefore, this study investigated the weighting of sensory systems in patients with CSM. Method Twenty-four individuals with CSM (CSM group) and 24 age-matched healthy adults (healthy control group) were analyzed in this observational study. The functional outcomes (modified Japanese Orthopaedic Association Scale [mJOA], Japanese Orthopaedic Association Cervical Myelopathy Questionnaire [JOACMEQ], Nurick scale) and static balance (eyes-open and eyes-closed conditions) were assessed for individuals with CSM before surgery, 3 and 6 months after surgery. Time-domain and time–frequency-domain variables of the center of pressure (COP) were analyzed to examine the weighting of the sensory systems. Results In the CSM group, lower extremity function of mJOA and Nurick scale significantly improved 3 and 6 months after surgery. Before surgery, the COP mean velocity and total energy were significantly higher in the CSM group than in the control group for both vision conditions. Compared with the control group, the CSM group exhibited lower energy content in the moderate-frequency band (i.e., proprioception) and higher energy content in the low-frequency band (i.e., cerebellar, vestibular, and visual systems) under the eyes-open condition. The COP mean velocity of the CSM group significantly decreased 3 months after surgery. The energy content in the low-frequency band (i.e., visual and vestibular systems) of the CSM group was closed to that of the control group 6 months after surgery under the eyes-open condition. Conclusion Before surgery, the patients with CSM may have had compensatory sensory weighting for postural control, with decreased weighting on proprioception and increased weighting on the other three sensory inputs. After surgery, the postural control of the patients with CSM improved, with decreased compensation for the proprioceptive system from the visual and vestibular inputs. However, the improvement remained insufficient because the patients with CSM still had lower weighting on proprioception than the healthy adults did. Therefore, patients with CSM may require balance training and posture education after surgery.

“…The JOACMEQ is a patient-based assessment for evaluating cervical compressive myelopathy, and several reports using this scoring system have been published to date. 7,[11][12][13][14] Regarding the QOL of patients with OPLL, several reports on postoperative axial neck pain have been published 12,15,16 ; however, to the best of our knowledge, detailed reports of cervical spine function based on large prospective multicenter series are lacking. Comprehensive evaluations of cervical spine function in patients with OPLL who underwent conservative treatment are important to understand the natural course of OPLL and can serve as a control when evaluating cervical spine function after surgery.…”

Ossification of the posterior longitudinal ligament (OPLL) is a progressive disease. The bridging of ossified lesions to the vertebral body gradually increases, thereby decreasing the mobility of the cervical spine; thus, cervical spine function may decrease over time. However, cervical spine function in patients with cervical OPLL has not been evaluated in large prospective studies. Therefore, we conducted a prospective multicenter study to clarify whether ossification spread can influence cervical spine function and quality of life (QOL) in patients with cervical OPLL. In total, 238 patients (162 men, 76 women; mean age, 63.9 years) were enrolled from 16 institutions. Each patient underwent whole spine computed tomography and was evaluated cervical spine function and QOL using the Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire (JOACMEQ). In the multivariate regression analysis, a higher neck VAS score and a larger number of bridge formations of OPLL in the whole spine were significant predictors of adverse outcomes related to cervical spine function. This is the first prospective multicenter study to reveal the impact of ossification spread on cervical spine function. These findings are important to understand the natural course of OPLL and can serve as controls when evaluating postoperative cervical spine function.
