Abstract
STUDY DESIGN Translation and psychometric testing of a questionnaire. OBJECTIVE Translation, adaptation, and validation of the Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire (JOACMEQ) to the Spanish language. SUMMARY OF BACKGROUND DATA Degenerative cervical myelopathy (DCM) has a clear impact on quality of life (QoL). The JOACMEQ is a self-administered questionnaire used to assess DCM-related disability and its impact on QoL. It is compound of five domains: Cervical Function, Upper Extremity Function, Lower Extremity Function, Blader Function, and QoL. Despite its increasing use, the JOACMEQ has not yet been translated and validated for Spanish-speaking patients. METHODS A total of 180 patients completed the Spanish version. Of these, 145 (80%) had DCM (mean age: 62.53; SD: 9.92), while 35 had neck pain without DCM (age: 52.71; SD: 10.29). The psychometric properties measured were construct validity, internal consistency, reproducibility, concurrent validity, and discriminatory ability. RESULTS We recruited 145 patients with DCM (mean age: 62.5) and 35 with cervical pain (mean age: 52.7). After factor analysis, our data showed very strong construct validity, with questions strongly loaded and clustered for five factors. Internal consistency proved high (Cronbach's α coefficient of 0.912). The intraclass correlation coefficient showed very good reproducibility for all domain (intraclass correlation coefficient range between 0.85 and 0.95). A high correlation between the JOACMEQ QoL domain and neck disability index was also found (Spearman's ρ=-0.847, P <0.01) confirming concurrent validity. The receiver operating characteristic curves proved to be significant in the upper (area under the curve=0.65, P =0.006) and lower (area under the curve=0.661, P =0.003) extremities, confirming discriminatory ability. CONCLUSIONS Our proposed Spanish version of the JOACMEQ retains the psychometric characteristics of the original JOACMEQ and could prove useful for the evaluation of patients with DCM in Spanish-speaking countries.

Abstract
STUDY DESIGN A prospective multicenter study. OBJECTIVE This study aims to evaluate patient-reported outcomes using the Japanese Orthopedic Association Cervical Myelopathy Evaluation Questionnaire (JOACMEQ) and clarify clinical factors that affect the therapeutic effects for patients with cervical ossification of the posterior longitudinal ligament (OPLL). SUMMARY OF BACKGROUND DATA Although previous studies identified factors that affected the surgical outcomes, their assessment was mainly based on the Japanese Orthopedic Association score, which only includes neurological function. Investigating this pathology through multiple functions and quality of life (QOL) is pivotal to understanding the comprehensive clinical pictures of the cervical OPLL and its therapeutic outcomes. MATERIALS AND METHODS This study was performed by the Japanese Multicenter Research Organization for Ossification of the Spinal Ligament. A total of 478 patients with myelopathy caused by cervical OPLL from 28 institutions were prospectively registered from 2014 to 2017 and followed up for 2 years. Of the patients, 168 received laminoplasties and fully completed questionnaires. Demographic information, imaging findings, and clinical outcomes were collected. Patients were grouped according to effective or ineffective surgical outcomes as defined by the JOACMEQ using logistic regression analyses. RESULTS Laminoplasty resulted in functional improvement in the cervical spine and upper extremity around 40% of the patients, while QOL showed only 21.4% ( P <0.01). Multivariable analyses revealed that younger age and a postoperative decrease in arm or hand pain were correlated with significantly improved function of the upper extremities. A reduction in lower limb pain favorably affected the postoperative lower extremity function. A postoperative reduction in upper extremity pain enhanced the QOL recovery. CONCLUSIONS Surgeons should recognize the diversity of surgical outcomes after laminoplasty and understand the necessity of pain management even after the surgery to enhance bodily functions and QOL in patients with cervical OPLL.

Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire as an outcome measure for ossification of posterior longitudinal ligament patients in East Asia: an investigation of reliability, validity, and responsiveness. ANNALS OF TRANSLATIONAL MEDICINE 2021; 9:1060. [PMID: 34422972 PMCID: PMC8339837 DOI: 10.21037/atm-20-8064] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 12/18/2020] [Accepted: 05/04/2021] [Indexed: 02/05/2023]
Abstract
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 SF-36 (r=0.25–0.50), and the bladder function and quality of life domains also had moderate correlations (r=0.25–0.50) with the mental component summary (MCS) of SF-36. JOACMEQ showed a variable responsiveness in different domains (effect size =0.17–0.84; standardized response means =0.15–0.85). Regarding postoperative improvements in the JOACMEQ score, mixed-model analysis revealed a significant difference in the quality of life domain between Chinese and Japanese patients (16.0±18.7 vs. 7.8±17.7, P<0.05). Conclusions JOACMEQ generally shows good reliability, good validity and mild responsiveness, and can identify the post-operative improvements in patients with OPLL in mainland China. Chinese OPLL patients showed a significantly larger improvement in postoperative quality of life compared to their Japanese counterparts.

Abstract
PURPOSE This study aimed to validate the simplified Chinese version of the Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire (JOACMEQ) for Chinese patients with cervical spondylotic myelopathy (CSM). METHODS The construct validity was conducted using confirmatory factor analysis (CFA). The convergent validity was based on factor loading, composite reliability (CR), and Pearson correlation coefficients (r). Internal consistency reliability was evaluated using Cronbach's α, test-retest reliability using intraclass correlation coefficients (ICC), and the ceiling and floor effects were also examined. RESULTS A total of 168 native Chinese-speaking patients were enrolled. The CFA indicated that construct validity did not meet the preset criteria to be considered as good. Except for Q 4-1, the factor loading was higher than the standard of 0.5, and the CR values ranged from 0.70 to 0.85. Strong to moderate correlations were found between other scales and the simplified Chinese JOACMEQ. The scale showed good internal consistency reliability (Cronbach's α 0.639-0.821), and test-retest reliability (ICC 0.760-0.916). Moreover, the ceiling effect was displayed from Q1 to Q4. CONCLUSIONS This study indicates that the simplified Chinese JOACMEQ is a reliable and valid measure of the functional status among Chinese patients with CSM.IMPLICATIONS FOR REHABILITATIONThe JOACMEQ was translated into the simplified Chinese and culturally adapted for Chinese-speaking patients with CSM for the first time.The simplified JOACMEQ demonstrated an excellent level of internal consistency and good test-retest reliability.The simplified Chinese JOACMEQ was reliable and valid for the measurement of the functional status among the patients with CSM.

Abstract
STUDY DESIGN A prospective questionnaire translation and validation. OBJECTIVE The aim of this study was to translate and cross-culturally adapt the Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire (JOACMEQ) into Traditional Chinese (Hong Kong) and to assess its validity, reliability, and sensitivity for differentiating cervical myelopathy (CM) and presence of acute neck/shoulder pain. SUMMARY OF BACKGROUND DATA CM frequently presents with various symptoms affecting patients' quality of life. Hence, a patient-oriented instrument such as JOACMEQ is necessary to assess patient-perceived outcomes of CM treatment. METHODS The English version of JOACMEQ was translated and adapted using double forward and single backward translations. The translated JOACMEQ was administered to patients with suspected CM, followed by the Traditional Chinese (Hong Kong) version of the Neck Disability Index (NDI), EuroQol five-dimension five-level (EQ-5D-5L), and Short Form-12 version 2 (SF-12v2) questionnaires. Construct validity of the domains was assessed using Spearman correlation test against domains with similar constructs. Internal consistency was assessed by Cronbach's alpha. Sensitivity of the adapted JOACMEQ was determined by known group comparisons. RESULTS A total of 100 patients were recruited. Psychometric testing of the translated JOACMEQ demonstrated an excellent overall internal consistency with Cronbach's α > 0.9, and good internal consistency of Lower Extremity Function (0.823) and Quality of Life (0.875) domains. Score of all domains of the translated JOACMEQ had significant correlations (P < 0.01-0.05) with nearly all domains of SF-12v2 and with both NDI and EQ-5D-5L scores. JOACMEQ was sensitive in detecting differences (P < 0.001) between subjects who had CM and those without, and also between those patients with/without CM experiencing current neck/shoulder pain. CONCLUSION Our translated JOACMEQ has satisfactory psychometric properties, including adequate clinical and construct validity, and internal consistency in patients with suspected/diagnosed CM and can differentiate between those with/without pain. It is demonstrated as a sensitive outcome measure for CM and neck/shoulder pain. LEVEL OF EVIDENCE 2.

Abstract
STUDY DESIGN Cross-sectional. PURPOSE Clinical outcome study comparing the Copenhagen Neck Functional Disability Scale (CNFDS) and modified Japanese orthopedic association (mJOA) assessment scales in patients with cervical spondylotic myelopathy (CSM). OVERVIEW OF LITERATURE Comparison of instruments that measure patient-reported outcomes is needed. METHODS A cross-sectional analysis was conducted. Ninety five patients with CSM were entered into the study and completed the CNFDS and the mJOA preoperatively and postoperatively. Correlation between the CNFDS and the mJOA was evaluated preoperatively and at the end of follow-up. Responsiveness to change of CNFDS and mJOA was also assessed. Clinical outcomes were also measured with the recovery rate of mJOA score at end of follow-up. RESULTS The mean age of patients was 58.2 (standard deviation, SD=8.7) years. Mean follow-up was 2.1 years (range, 1 to 4 years). The mJOA correlated strongly with the CNFDS score preoperatively and postoperatively (r=-0.81 and -0.82, respectively; p<0.001). The CNFDS and the mJOA were able to detect changes after the surgery (p<0.001). The mean mJOA recovery rate was 51.8% (SD=13.1%). CONCLUSIONS Surgery for the treatment of patients with CSM is an efficacious procedure. CNFDS and mJOA scores have a strong correlation in measuring disability among CSM patients.

Abstract
BACKGROUND The Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire (JOACMEQ) was developed to resolve problems associated with the original evaluation of cervical myelopathic patients. The aim of this study was to translate the JOACMEQ into Thai as per international recommendations, and to test its reliability and validity in the Thai context METHODS The JOACMEQ was translated into Thai, using international guidelines. Cervical myelopathy patients (n = 70; 31 males) were asked to complete the Thai version JOACMEQ twice (4 weeks apart). Test-retest reliability was analyzed using the intra-class correlation coefficient (ICC). Internal consistencies were analyzed using Cronbach's alpha, while the construct validity was compared with the Thai version modified SF-36; using the Spearman's rank correlation coefficient. RESULTS The Thai JOACMEQ produced good reliability (i.e., the ICC was >0.9 in 2 parameters and >0.8 in one). Overall the Cronbach's α for the 24 questions showed very high internal consistency (Cronbach's α > 0.8) and almost all Cronbach's α showed satisfactory internal consistency except for bladder function. The Spearman's rank correlation for all the JOACMEQ parameters had a positive correlation with all Thai SF 36 subscales, especially the quality of life parameter, which showed a strong correlation with all SF-36 subscales. CONCLUSION The Thai version of the JOACMEQ had satisfactory internal consistency and test-retest reliability: it also had good construct validity. It can therefore be used as a reliable tool for assessing quality of life for cervical myelopathy patients in Thailand.

Outcome Measures of Functionality, Social Interaction, and Pain in Patients with Cervical Spondylotic Myelopathy: A Validation Study for the Iranian Version of the Copenhagen Neck Functional Disability Scale. Asian Spine J 2015; 9:901-8. [PMID: 26713123 PMCID: PMC4686396 DOI: 10.4184/asj.2015.9.6.901] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/19/2015] [Revised: 03/10/2015] [Accepted: 03/22/2015] [Indexed: 12/22/2022] Open
Abstract
STUDY DESIGN Cross-sectional. PURPOSE To translate and validate the Iranian version of the Copenhagen Neck Functional Disability Scale (CNFDS). OVERVIEW OF LITERATURE Instruments measuring patient-reported outcomes should satisfy certain psychometric properties. METHODS Ninety-three cases of cervical spondylotic myelopathy were entered into the study and completed the CNFDS pre and postoperatively at the 6 month follow-up. The modified Japanese Orthopedic Association Score was also completed. The internal consistency, test-retest, convergent validity, construct validity (item scale correlation), and responsiveness to change were assessed. RESULTS Mean age of the patients was 54.3 years (standard deviation, 8.9). The Cronbach α coefficient was satisfactory (α=0.84). Test-retest reliability as assessed by the intraclass correlation coefficient analysis was 0.95 (95% confidence interval, 0.92-0.98). The modified Japanese Orthopedic Association score correlated strongly with the CNFDS score, lending support to its good convergent validity (r=-0.80; p<0.001). Additionally, the correlation of each item with its hypothesized domain on the CNFDS was acceptable, suggesting that the items had a substantial relationship with their own domains. These results also indicate that the instrument was responsive to change (p<0.0001). CONCLUSIONS The findings suggest that the Iranian version of the CNFDS is a valid measure to assess functionality, social interaction, and pain among patients with cervical spondylotic myelopathy.

Responsiveness of the Chinese versions of the Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire and Neck Disability Index in postoperative patients with cervical spondylotic myelopathy. Spine (Phila Pa 1976) 2015; 40:1315-21.

Abstract
STUDY DESIGN Prospective cohort study. OBJECTIVE To evaluate the postoperative responsiveness of the Chinese versions of the Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire (JOACMEQ) and the Neck Disability Index (NDI) in a cohort of patients with cervical spondylotic myelopathy. SUMMARY OF BACKGROUND DATA We have recently completed the translation and cross-cultural adaptation of a Chinese version of JOACMEQ. However, the postoperative responsiveness of the Chinese JOACMEQ and how it compares with the more commonly used NDI remain undetermined. METHODS Forty-five patients with cervical spondylotic myelopathy undergoing surgical decompression were recruited. All patients completed the Chinese JOACMEQ and the NDI preoperatively and again at 3-month follow-up together with an 11-point Global Rating of Change scale. Patients were dichotomized either as "Improved" or "Stable" on the basis of Global Rating of Change. Paired t test, standardized effect sizes, and Guyatt responsiveness index were used to determine internal responsiveness. External responsiveness was evaluated by the area under the receiver operating characteristic curve and the minimal clinically important change was determined as the optimal cutoff point for patient discrimination anchor-based on Global Rating of Change classification. RESULTS Bladder function and quality of life (QOL) domains (P < 0.03) of the JOACMEQ and the NDI (P = 0.004) reached statistically significant difference with the paired t test. After the dichotomization, the standardized effect size was strong for the QOL domain in the improved group (0.85) and the Cervical spine function (0.97) in the stable group, respectively. Based on the Guyatt responsiveness index, strong responsiveness was found for the Bladder function (0.88) and QOL (0.76) domains of the JOACMEQ and moderate responsiveness (0.55) for the NDI. The Bladder function (area = 0.82; minimal clinically important change = 6) and QOL (0.83; minimal clinically important change = 8.5) also produced largest area under the receiver operating characteristic curve. CONCLUSION Bladder function and QOL domains of the JOACMEQ seem to demonstrate the strongest postoperative responsiveness and thus may be more appropriate than NDI when attempting to determine treatment efficacy in cervical spondylotic myelopathy. LEVEL OF EVIDENCE 3.
