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

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

Background

The aim of this study is to investigate the reliability, validity, and responsiveness of JOACMEQ for CSM patients in mainland China.

Methods

A retrospective review was performed on 91 patients with CSM in our hospital from March 2015 to June 2015. Patients completed the JOACMEQ, the mJOA and the SF-36 questionnaires during the process. Cronbach's α was used to evaluate the internal consistency reliability, and test–retest reliability was checked. An exploratory factor analysis was used to determine the correlations among the JOACMEQ questions and the construct validity. The concurrent validity was assessed by Spearman correlation coefficient. The internal responsiveness was determined by effect sizes and standardized response means. External responsiveness was determined by the area under the receiver operating characteristic curve on the basis of the Youden Index.

Results

The mean age of patients was 57.61 years old. The mean follow-up was 24 months. JOACMEQ showed a good internal consistency (Cronbach's α, 0.897). Test–retest reliability showing good result (Pearson's correlation, 0.695–0.905). Our data were amenable to factor analysis (KMO = 0.816, Bartlett's test, χ²(45) = 1199.99, p < 0.001), and five factors above 1 were strongly loaded and clustered for each of the five factors. Comparing the scales preoperative to those 2 years postoperative, the average scores of the subscales all increased, and both the ES and SRM showing satisfied responsiveness. In external responsiveness analysis, the recovery rate a appeared to be most responsive to post-operative improvement.

Conclusions

The Simplified Chinese version of JOACMEQ was well-developed with great reliability and sensitive responsiveness. Our study demonstrated that JOACMEQ has content psychometric properties to identify postoperative improvements in CSM patients.

Abstract

STUDY DESIGN

Surgeon survey.

PURPOSE

To study the various surgical practices of different surgeons in the Asia-Pacific region.

OVERVIEW OF LITERATURE

Given the diversity among Asia-Pacific surgeons, there is no clear consensus on the preferred management strategies for cervical myelopathy. In particular, the role of prophylactic decompression for silent cervical spinal stenosis is under constant debate and should be addressed.

METHODS

Surgeons from the Asia-Pacific Spine Society participated in an online questionnaire comprising 50 questions. Data on clinical diagnosis, investigations and outcome measures, approach to asymptomatic and silent cervical spinal stenosis, guidelines for surgical approach, and postoperative immobilization were recorded. All parameters were analyzed by the Mantel-Haenszel test.

RESULTS

A total of 79 surgeons from 16 countries participated. Most surgeons used gait disturbance (60.5%) and dyskinetic hand movement (46.1%) for diagnosis. Up to 5.2% of surgeons would operate on asymptomatic spinal stenosis, and 18.2% would operate on silent spinal stenosis. Among those who would not operate, most (57.1%) advised patients on avoidance behavior and up to 9.5% prescribed neck collars. For ossification of the posterior longitudinal ligament (OPLL), anterior removal was most commonly performed for one-level disease (p<0.001), whereas laminoplasty was most commonly performed for two- to four-level disease (p=0.036). More surgeons considered laminectomy and fusion for multilevel OPLL. Most surgeons generally preferred to use a rigid neck collar for 6 weeks postoperatively (p<0.001).

CONCLUSIONS

The pooled recommendations include prophylactic or early decompression surgery for patients with silent cervical spinal stenosis, particularly OPLL. Anterior decompression is primarily suggested for one- or two-level disease, whereas laminoplasty is preferred for multilevel disease.

Abstract

PURPOSE

To compare the clinical and radiological outcomes between skipped-level and all-level plating for cervical laminoplasty.

METHODS

Patients with cervical spondylotic myelopathy (CSM) treated by open-door laminoplasty with minimum 2-year postoperative follow-up were included. All patients had opening from C3-6 or C3-7 and were divided into skipped-level or all-level plating groups. Japanese Orthopaedic Association (JOA) scores and canal measurements were obtained preoperatively, immediate (within 1 week) postoperatively, and at 2, 6 weeks, 3, 6 and 12 months postoperatively. Paired t test was used for comparative analysis. Receiver operating characteristic analysis was used to determine the canal expansion cutoff for spring-back closure.

RESULTS

A total of 74 subjects were included with mean age of 66.1 ± 11.3 years at surgery. Of these, 32 underwent skipped-level plating and 42 underwent all-level plating. No significant differences were noted between the two groups at baseline and follow-up. Spring-back closure was observed in up to 50% of the non-plated levels within 3 months postoperatively. The cutoff for developing spring-back closure was 7 mm canal expansion for C3-6. No differences were observed in JOA scores and recovery rates between the two groups. None of the patients with spring-back required reoperation.

CONCLUSIONS

There were no significant differences between skipped-level and all-level plating in terms of JOA or recovery rate, and canal diameter differences. This has tremendous impact on saving costs in CSM management as up to two plates per patient undergoing a standard C3-6 laminoplasty may be omitted instead of four plates to every level to achieve similar clinical and radiological outcomes.
