Cross-cultural adaptation of The Japanese Orthopaedic Association Back Pain Evaluation Questionnaire: A methodological systematic review.

BACKGROUND: The Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) is a reliable and sensitive measure of disability to determine functional status and evaluate curative effects in low back pain, it has now been cross-cultural translated into many other languages and adapted for use in different countries. We aim to evaluate the translation procedures and measurement properties of cross-cultural adaptations of the JOABPEQ. METHODS: Studies related to cross-cultural adaptation of the JOABPEQ in a specific language/culture were searched in PubMed, Embase, CINAHL, SciELO, PsycINFO, SinoMed, and Web of Science from their inception to March 2022. The Guidelines for the Process of Cross-Cultural Adaptation of Self-Report Measures and the Consensus-based Standards for the Selection of Health Status Measurement Instruments guideline were used for evaluation. RESULTS: Nine different versions of cross-cultural JOABPEQ adaptations in 8 different languages/cultures were included. The adaptation process was not strictly performed, such as standard forward translation and expert committee review were rarely reported. Content validity (8/9), floor and ceiling effects (3/9), reliability (4/9), and interpretability (6/9) were assessed in most of the adaptations, while agreement (2/9), responsiveness (2/9), and the internal consistency (2/9) were not. JOABPEQ can replace functional and quality of life score to reduce the burden of scientific research. CONCLUSION: We recommend Persian-Iranian, simplified Chinese-Chinese Mandarin, Thai and Gunaydin G's Turkish adaptations for application. The numerical pain rating scale/visual analogue scale in low back pain and lower extremities, as well as numbness in lower extremities could not be neglected in JOABPEQ adaptations.

Examination of a Regression Model to Quantify the Severities of Low Back Pain and Lower Limb Symptoms in Patients with Lumbar Spinal Stenosis / The Japanese Journal of Rehabilitation Medicine

Objective：The Japanese Orthopaedic Association Low Back Pain Evaluation Questionnaire (JOABPEQ) consists of 25 questions, which allows for the multifaceted evaluation of patients with low back pain. In this study, we aimed to investigate whether the JOABPEQ could be used to construct a regression model to quantify low back pain, lower limb symptoms, and hip range of motion (ROM) in patients with lumbar spinal stenosis.Methods：We evaluated 115 patients with lumbar spinal stenosis scheduled to undergo surgery at our hospital. We measured the degrees of low back pain, lower leg pain, and lower leg numbness using the visual analog scale before the surgery. In addition, we measured the ROM of the hip joint during flexion, external rotation, and internal rotation. All responses of the JOABPEQ and physical function data were subjected to a partial least-squares (PLS) regression analysis.Results：Low back pain, lower limb pain, lower limb numbness, and hip ROM during flexion could each be used for significant regression models with JOABPEQ items. However, the hip ROMs during external and internal rotation could not be used for regression models with the JOABPEQ.Conclusion：On the basis of the results of the PLS regression analysis in this study, the degree of pain symptoms in patients with lumbar spinal stenosis may be quantified with the JOABPEQ items. Furthermore, the flexion angle of the hip ROM was quantified using the JOABPEQ items. The results of this study may indicate an effective means for establishing treatment plans for physical therapy.

Outcome measures reflecting patient satisfaction following decompression surgery for lumbar spinal stenosis: Comparison of major outcome measures.

OBJECTIVE: Decompression surgery is the standard treatment for lumbar spinal stenosis (LSS); however, despite the good clinical outcomes reported for this procedure, a relatively high dissatisfaction rate has been reported. We hypothesized that the previously used outcome measures do not accurately reflect patient satisfaction (PS). This study aimed to examine which outcome measures reflect PS accurately in patients undergoing decompression for LSS. PATIENTS AND METHODS: Patients with LSS treated with lumbar decompression surgery between January 2014 and March 2016 were enrolled if they had the preoperative and final follow-up questionnaires including the Numeric Rating Scale (NRS), Roland-Morris Disability Questionnaire (RMDQ), Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ), and Short Form-8 (SF-8). PS was evaluated using the question, "How satisfied are you with the overall result of your back operation?". There are four possible answers consisting of "very satisfied (4-point)", "somewhat satisfied (3-point)", "somewhat dissatisfied (2-point)", or "very dissatisfied (1-point)". The Spearman correlation coefficient between PS and each questionnaire was calculated. RESULTS: Postoperative JOABPEQ had strong correlation with PS (r > 0.6) whereas NRS, RMDQ and SF-8 had moderate correlation (0.4

The reliability and validity of the Korean version of the Japanese orthopaedic association back pain evaluation questionnaire.

[Purpose] The purpose of this study was to establish the reliability and validity of the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) translated into Korean for use with patients' low back pain. [Subjects and Methods] Sixty-two subjects with low back pain, 28 men and 34 women, participated in the study. Reliability was determined by using the intra class correlation coefficient and Cronbach's alpha for internal consistency. Validity was examined by correlating the JOABPEQ scores with the 36 item short form health survey (SF 36). [Results] Test-retest reliability was 0.75-0.83. The criterion-related validity was established by comparison with the Korean version of the SF 36. [Conclusion] The Korean version of the JOABPEQ was shown to be a reliable and valid instrument for assessing low back pain.
