Prediction of lumbar disc herniation resorption in symptomatic patients: a prospective, multi-imaging and clinical phenotype study. Spine J 2023; 23:247-260. [PMID: 36243388 DOI: 10.1016/j.spinee.2022.10.003] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/26/2022] [Revised: 09/22/2022] [Accepted: 10/04/2022] [Indexed: 11/05/2022]
Abstract
BACKGROUND CONTEXT Symptomatic lumbar disc herniations (LDH) are very common. LDH resorption may occur by a "self-healing" process, however this phenomenon remains poorly understood. By most guidelines, if LDH remains symptomatic after 3 months and conservative management fails, surgical intervention may be an option. PURPOSE The following prospective study aimed to identify determinants that may predict early versus late LDH resorption. STUDY DESIGN/SETTING Prospective study with patients recruited at a single center. PATIENT SAMPLE Ninety-three consecutive patients diagnosed with acute symptomatic LDH were included in this study (n=23 early resorption and n=67 late resorption groups) with a mean age of 48.7±11.9 years. OUTCOMES MEASURE Baseline assessment of patient demographics (eg, smoking status, height, weight, etc.), herniation characteristics (eg, the initial level of herniation, the direction of herniation, prevalence of multiple herniations, etc.) and MRI phenotypes (eg, Modic changes, end plate abnormalities, disc degeneration, vertebral body dimensions, etc.) were collected for further analysis. Lumbar MRIs were performed approximately every 3 months for 1 year from time of enrollment to assess disc integrity. METHODS All patients were managed similarly. LDH resorption was classified as early (<3 months) or late (>3 months). A prediction model of pretreatment factors was constructed. RESULTS No significant differences were noted between groups at any time-point (p>.05). Patients in the early resorption group experienced greater percent reduction of disc herniation between MRI-0-MRI-1 (p=.043), reduction of herniation size for total study duration (p=.007), and percent resorption per day compared to the late resorption group (p<.001). Based on multivariate modeling, greater L4 posterior vertebral height (coeff:14.58), greater sacral slope (coeff:0.12), and greater herniated volume (coeff:0.013) at baseline were found to be most predictive of early resorption (p<.05). CONCLUSIONS This is the first comprehensive imaging and clinical phenotypic prospective study, to our knowledge, that has identified distinct determinants for early LDH resorption. Early resorption can occur in 24.7% of LDH patients. We developed a prediction model for early resorption which demonstrated great overall performance according to pretreatment measures of herniation size, L4 posterior body height, and sacral slope. A risk profile is proposed which may aid clinical decision-making and managing patient expectations.

Abstract
BACKGROUND Lumbar disc herniations (LDH) are among the most common spinal conditions. Despite increased appreciation for the importance of social determinants of health, the role that these factors play in patients with lumbar disc herniations is poorly defined. PURPOSE To elucidate the association between insurance status and baseline patient reported outcome measures (PROMs) in the setting of lumbar disc herniations. STUDY DESIGN/SETTING Retrospective cohort study PATIENT SAMPLE: Baseline patient-reported outcome measures (PROMS) were reviewed from 924 adult patients presenting for treatment of lumbar disc herniation within our institutional healthcare system (2015-2020). OUTCOME MEASURES The Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function Short Form 10a (PF10a), PROMIS Global-Mental, PROMIS Global-Physical, and visual analogue scale (VAS) for back and leg pain were assessed. METHODS PROMIS scores at presentation were defined at the primary outcome and insurance status as the primary predictor. Differences in clinical and sociodemographic characteristics between our cohorts, stratified by insurance status, were evaluated using Wilcoxon rank-sum or chi-squared testing. We used multivariable negative binomial regression modeling to adjust for potential confounders including age, gender, race, language, ethnicity, comorbidity index, and median geospatial household income. RESULTS We included 924 patients, with mean age of 58.4 +/- 15.2 years and 52.6% male prevalence. Patients insured through Medicaid were more likely to be Black, Hispanic, and non-English speaking patients compared with the commercially insured. The Charlson Comorbidity index was significantly higher in the Medicare group. Following adjusted analysis, patients with Medicaid insurance had significantly worse PF10a (IRR, 0.90, 95% CI 0.85-0.96), as well as PROMIS Global-Physical score (IRR 0.88, 95% CI 0.82-0.94), and VAS low back pain (IRR 1.20, 95% CI 1.04-1.40) when compared to the commercially insured. CONCLUSIONS We encountered worse physical function, mental, and pain-related patient-reported outcomes for those with Medicaid insurance in a population of patients presenting for evaluation of lumbar disc herniation. These findings, including worse depression, anxiety, and higher axial back pain scores, merit further investigation into potential health system asymmetries, and should be accounted for by treating providers.

Abstract
Introduction Condoliase is a newly approved drug that improves symptoms associated with lumbar disk herniation (LDH) by intradiscal administration. This study aimed to evaluate the mid-term outcomes of condoliase injection, examine the adverse events, including cases that required surgery after condoliase administration, and verify cases in which condoliase could be effective. Methods We enrolled patients with LDH who were treated conservatively for at least six weeks and received condoliase. We assessed the visual analog scale (VAS) score, Japanese Orthopaedic Association Back Pain Evaluation Questionnaire, Oswestry Disability Index, disk height, and disk degeneration for up to 6 months, and we examined the complications. Furthermore, a 50% or more improvement in leg pain VAS score was considered effective. Factors related to symptom improvement were investigated by determining whether lower limb pain improved in six months. Results In total, 84 patients were recruited (52 men, 32 women; mean age, 44.2 ± 17.1 [16-86 years]). The duration of illness was 6.7 ± 6.8 (1.5-30) months. All patient-based outcomes significantly improved at 4 weeks after the administration compared with pretreatment. The intervertebral disc height decreased significantly at four weeks after condoliase administration compared with that before administration. Progression of intervertebral disc degeneration occurred in 50% of the patients. Eleven patients underwent herniotomy due to poor treatment effects. Moreover, treatment in 77.4% of the patients was considered effective. A logistic regression analysis revealed that L5/S1 disk administration (p = 0.029; odds ratio, 5.94; 95% confidence interval, 1.20-29.45) were significantly associated with clinical effectiveness. Conclusions Condoliase disk administration improved pain and quality of life over time. Condoliase disk administration was more effective in L5/S1 intervertebral administration.

Abstract
ABSTRACT Objective: To evaluate the influence between the time elapsed since the onset of symptoms and the surgery of lumbar HNP in the final functional recovery of the comprehensive treatment of patients. Methods: Retrospective descriptive study of cases of HNP treated by lumbar discectomy between 2009 and 2015 by the spine team of the Hospital San José, using SPSS (version 22 of IBM) for the statistical analysis. Results: Of 110 patients subject to surgery, 54 were recruited (22 women and 32 men), between 18 and 75 years old, with an average age of 43 years. Eighty percent of patients are active workers, 76% without comorbidities. The predominant level affected was L4/L5 with 52% of the cases. The mean progression time of the symptoms before the first consultation was 27 months, the waiting time between the consultation and the surgery was 5.6 months. Conclusions: Eighty-six percent of the patients -presented good results in VAS. The Oswestry questionnaire reached a positive result in 90%, a minimum disability in 40%, moderate in 50% and maximum in 10%. No statistical relationship was achieved between any of the evaluated variables and the outcome of the surgery. Level of Evidence IV; Therapeutic Study - Investigation of Treatment Results.

Abstract
STUDY DESIGN This is a retrospective cohort study. OBJECTIVE This study aims to characterize the effect of preoperative symptom duration on postoperative outcomes after minimally invasive lumbar microdiscectomy (MIS LD). SUMMARY OF BACKGROUND DATA It is unknown whether extended nonoperative treatment before MIS LD has implications for long-term clinical outcomes even after surgery is performed. MATERIALS AND METHODS A prospectively maintained surgical registry of patients undergoing MIS LD by a single surgeon between 2013 and 2017 was reviewed. Preoperative symptom duration was dichotomized into 2 groups (≤6 and >6 mo). Only patients with full clinical data at 6 months postoperative follow-up were included in the study. Clinical outcomes were assessed at 6, 12 weeks, and 6 months after surgery. The number of patients obtaining a minimum clinically important difference was assessed. Groups were compared with the χ analysis and the student t tests for categorical and continuous data, respectively. RESULTS In total, 94 patients were identified. A total of 45 patients (47.9%) had symptom duration ≤6 months. No differences in baseline characteristics were found (P>0.05). Patients with shorter symptom duration had significantly greater improvement in Oswestry Disability Index scores at 6 weeks (P=0.004), 12 weeks (P=0.022), and 6 months (P=0.005). Patients with shorter duration of symptoms also obtained minimum clinically important difference for Oswestry Disability Index at a greater rate than those with longer duration of symptoms (P=0.015). CONCLUSIONS Although patients who underwent MIS LD within 6 months of symptom onset had similar baseline characteristics compared with patients who underwent surgery after 6 months of symptoms, the patients with longer preoperative symptom duration had worse functional outcomes at 6 months after surgery. These results suggest that earlier MIS lumbar microdiscectomy may provide a functional benefit for patients. Further studies should therefore evaluate the efficacy of nonoperative treatment in the setting of lumbar herniated nucleus pulposus, as prolonged conservative management may potentially impair functional recovery after surgery.

Abstract
STUDY DESIGN Psychometric test of the cross-cultural adaptation the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) in low back pain (LBP) patients. OBJECTIVE To investigate the agreement, responsiveness, and minimal important change (MIC) of the simplified Chinese version of the JOABPEQ in LBP patients. SUMMARY OF BACKGROUND DATA The factor structure, internal consistency, test-retest reliability, validity, floor and ceiling effect of simplified Chinese JOABPEQ have been tested, while the agreement, responsiveness, and MIC were required. METHODS The agreement, responsiveness, and MIC of the simplified Chinese version were assessed by completing the Chinese JOABPEQ twice. Agreement was tested with Bland-Altman plot. Responsiveness was operationalized using receiver operating characteristic analyses. The anchor-based method was used to calculate MIC. RESULTS One hundred sixty-two of 184 patients returned to finish the booklet twice were available for analysis (response rate: 88.0%). While the responsiveness, the area under the curves of each subscale were ranged from 0.746 to 0.875, which meant a good responsiveness. While the MIC (MIC%) of simplified Chinese JOABPEQ was 19.28 (44.98%) for Q1 Low back pain, 15.20 (24.13%) for Q2 Lumbar function, 15.79 (22.76%) for Q3 Walking ability, 9.58 (19.86%) for Q4 Social life function, 7.33 (17.28%) for Q5 Mental health. While compared with the MIC, only the Q3 Walking ability had a positive rating for agreement in the Bland-Altman plot. CONCLUSION The simplified Chinese JOABPEQ has positive agreement of Q3 Walk ability and acceptable to excellent responsiveness of all the subscales. The MICs for subscales of the simplified Chinese JOABPEQ ranged from 7.33 to 19.28 points. LEVEL OF EVIDENCE 3.

Abstract
OBJECTIVES Pain relief has been shown to be the most frequently reported goal by patients undergoing lumbar disc surgery. There is a lack of systematic research investigating the course of postsurgical pain intensity and factors associated with postsurgical pain. This systematic review focuses on pain, the most prevalent symptom of a herniated disc as the primary outcome parameter. The aims of this review were (1) to examine how pain intensity changes over time in patients undergoing surgery for a lumbar herniated disc and (2) to identify socio-demographic, medical, occupational and psychological factors associated with pain intensity. METHODS Selection criteria were developed and search terms defined. The initial literature search was conducted in April 2015 and involved the following databases: Web of Science, Pubmed, PsycInfo and Pubpsych. The course of pain intensity and associated factors were analysed over the short-term (≤ 3 months after surgery), medium-term (> 3 months and < 12 months after surgery) and long-term (≥ 12 months after surgery). RESULTS From 371 abstracts, 85 full-text articles were reviewed, of which 21 studies were included. Visual analogue scales indicated that surgery helped the majority of patients experience significantly less pain. Recovery from disc surgery mainly occurred within the short-term period and later changes of pain intensity were minor. Postsurgical back and leg pain was predominantly associated with depression and disability. Preliminary positive evidence was found for somatization and mental well-being. CONCLUSIONS Patients scheduled for lumbar disc surgery should be selected carefully and need to be treated in a multimodal setting including psychological support.

Abstract
INTRODUCTION Herniated lumbar disc (HLD) is arguably the most common spinal disorder requiring surgical intervention. Although the term is fairly straightforward, the exact pathology and thus the clinical picture and natural history may vary. Therefore, it is immensely difficult to formulate universal guidelines for surgical treatment. AIM The aim of this paper is to organize the terminology and clear the inconsistencies in phraseology, review treatment options and gather available published evidence to address the clinical questions to create a set of clinical guidelines in relevant to the topic. METHODS AND RESULTS Twelve queries, addressing optimal surgical treatment of the HLD have been formulated. The results, based on the literature review are described in the present work. The final product of the analysis was a set of guidelines for the surgical treatment of symptomatic HLD. Categorized into four tiers based on the level of evidence (I-III and X), they have been designed to assist in the selection of optimal, effective treatment leading to the successful outcome. CONCLUSIONS The evidence based medicine (EBM) is becoming ever more popular among spinal surgeons. Unfortunately this is not always feasible. Lack of uniform guidelines and numerous conflicts of interest introduce flaws in the decision making process. The key role of experts and professional societies is to provide high value recommendation based on the most current literature. Present work contains a set of guidelines for the surgical treatment of HLD officially endorsed by the Polish Spine Surgery Society.

Abstract
BACKGROUND Although previous studies have illustrated improvements in surgical cohorts for patients with intervertebral disc herniation, there are limited data on predictors of long-term outcomes comparing surgical and nonsurgical outcomes. QUESTIONS/PURPOSES We assessed outcomes of operative and nonoperative treatment for patients with intervertebral disc herniation and symptomatic radiculopathy at 8 years from the Spine Patient Outcomes Research Trial. We specifically examined subgroups to determine whether certain populations had a better long-term outcome with surgery or nonoperative treatment. METHODS Patients with symptomatic lumbar radiculopathy for at least 6 weeks associated with nerve root irritation or neurologic deficit on examination and a confirmed disc herniation on cross-sectional imaging were enrolled at 13 different clinical sites. Patients consenting to participate in the randomized cohort were assigned to surgical or nonoperative treatment using variable permuted block randomization stratified by site. Those who declined randomization entered the observational cohort group based on treatment preference but were otherwise treated and followed identically to the randomized cohort. Of those in the randomized cohort, 309 of 501 (62%) provided 8-year data and in the observational group 469 of 743 (63%). Patients were treated with either surgical discectomy or usual nonoperative care. By 8 years, only 148 of 245 (60%) of those randomized to surgery had undergone surgery, whereas 122 of 256 (48%) of those randomized to nonoperative treatment had undergone surgery. The primary outcome measures were SF-36 bodily pain, SF-36 physical function, and Oswestry Disability Index collected at 6 weeks, 3 months, 6 months, 12 months, and then annually. Further analysis studied the following factors to determine if any were predictive of long-term outcomes: sex, herniation location, depression, smoking, work status, other joint problems, herniation level, herniation type, and duration of symptoms. RESULTS The intent-to-treat analysis of the randomized cohort at 8 years showed no difference between surgical and nonoperative treatment for the primary outcome measures. Secondary outcome measures of sciatica bothersomeness, leg pain, satisfaction with symptoms, and self-rated improvement showed greater improvement in the group randomized to surgery despite high levels of crossover. The as-treated analysis of the combined randomized and observational cohorts, adjusted for potential confounders, showed advantages for surgery for all primary outcome measures; however, this has the potential for confounding from other unrecognized variables. Smokers and patients with depression or comorbid joint problems had worse functional outcomes overall (with surgery and nonoperative care) but similar surgical treatment effects. Patients with sequestered fragments, symptom duration greater than 6 months, those with higher levels of low back pain, or who were neither working nor disabled at baseline showed greater surgical treatment effects. CONCLUSIONS The intent-to-treat analysis, which is complicated by high rates of crossover, showed no difference over 8 years for primary outcomes of overall pain, physical function, and back-related disability but did show small advantages for secondary outcomes of sciatica bothersomeness, satisfaction with symptoms, and self-rated improvement. Subgroup analyses identified those groups with sequestered fragments on MRI, higher levels of baseline back pain accompanying radiculopathy, a longer duration of symptoms, and those who were neither working nor disabled at baseline with a greater relative advantage from surgery at 8 years.

Abstract
BACKGROUND The impact of the duration of preoperative symptoms on outcomes after lumbar discectomy has not been sufficiently answered in a single study but is a potentially important clinical variable. QUESTIONS/PURPOSES A systematic review was performed to answer two questions: (1) Does symptomatic duration before surgery influence functional recovery after lumbar discectomy? (2) What is the time point for intervention beyond which the extent of postoperative recovery might be compromised? METHODS The systematic review began with a query of PubMed using a structured algorithm comprised of medical subject heading terms. This was supplemented by a keyword search in PubMed along with queries of Embase, Scopus, and Web of Science and searches of reference lists as well as the tables of contents of relevant journals. Eligible studies were those that evaluated aspects of recovery after elective discectomy and stratified duration of symptoms before surgery. Included papers were abstracted by two authors and determinations regarding the period of symptom duration and its impact on outcome were recorded. Eleven studies met all inclusion criteria. No prospectively randomized trials addressed our study questions. RESULTS Nine of 11 studies, four of which were prospective, maintained that longer symptom duration adversely impacted postsurgical recovery. There were substantial differences among the critical periods of symptom duration reported by individual studies, which ranged from 2 to 12 months. A preponderance of studies (five of nine) reported that surgical interventions could be performed at periods of 6 months or greater without impacting recovery. CONCLUSIONS Longer symptom duration had an adverse impact on results in most studies after lumbar discectomy. A possible point beyond which outcomes may be compromised is 6 months after symptom onset. Limitations in the literature surveyed, however, prevent firm conclusions.

Abstract
Study Design Literature review. Objective Since the 1970s, spine surgeons have commonly required 6 weeks of failed conservative treatment prior to considering surgical intervention for various spinal pathologies. It is unclear, however, if this standard has been validated in the literature. The authors review the natural history, outcomes, and cost-effectiveness studies relating to the current standard of 6 weeks of nonoperative care prior to surgery for patients with spinal pathologies. Methods A systematic Medline search from 1953 to 2013 was performed to identify natural history, outcomes, and cost-effectiveness studies relating to the optimal period of conservative management prior to surgical intervention for both cervical and lumbar radiculopathy. Demographic information, operative indications, and clinical outcomes are reviewed for each study. Results A total of 5,719 studies were identified; of these, 13 studies were selected for inclusion. Natural history studies demonstrated that 88% of patients with cervical radiculopathy and 70% of patients with lumbar radiculopathy showed improvement within 4 weeks following onset of symptoms. Outcomes and cost-effectiveness studies supported surgical intervention within 8 weeks of symptom onset for both cervical and lumbar radiculopathy. Conclusions There are limited studies supporting any optimal duration of conservative treatment prior to surgery for cervical and lumbar radiculopathy. Therefore, evidence-based conclusions cannot be made. Based on the available literature, we suggest that an optimal timing for surgery following cervical radiculopathy is within 8 weeks of onset of symptoms. A shorter period of 4 weeks may be appropriate based on natural history studies. Additionally, we found that optimal timing for surgery following lumbar radiculopathy is between 4 and 8 weeks. A prospective study is needed to explicitly identify the optimal duration of conservative therapy prior to surgery so that costs may be reduced and patient outcomes improved.

Abstract
Herniation of nucleus pulposus leading to leg pain is the commonest indication for lumbar spine surgery. However, there is no consensus when to stop conservative treatment and when to consider for surgery. A systematic review of literature was done to find a consensus on the issue of when should surgery be performed for herniation of nucleus pulposus in lumbar spine was conducted. Electronic database searches of Medline, Embase and Pubmed Central were performed to find articles relating to optimum time to operate in patients with herniation of nucleus pulposus in lumbar spine, published between January 1975 and 10 December 2012. The studies were independently screened by two reviewers. Disagreements between reviewers were settled at a consensus meeting. A scoring system based on research design, number of patients at final followup, percentage of patients at final followup, duration of followup, journal impact factor and annual citation index was devised to give weightage to Categorize (A, B or C) each of the articles. Twenty one studies fulfilled the criteria. Six studies were of retrospective design, 13 studies were of Prospective design and two studies were randomized controlled trials. The studies were categorized as: Two articles in category A (highest level of evidence), 12 articles in category B (moderate level of evidence) while seven articles in Category C (poor level of evidence). Category A studies conclude that duration of sciatica prior to surgery made no difference to the outcome of surgery in patients with herniation of nucleus pulposus in the lumbar spine. Ten out of 12 studies in Category B revealed that longer duration of sciatica before surgery leads to poor results while 2 studies conclude that duration of sciatica makes no difference to outcome. In category C, five studies conclude that longer duration of sciatica before surgery leads to poor outcome while two studies find no difference in outcome with regards to duration of sciatica. A qualitative and quantitative analysis was performed which favoured the consensus that longer duration of sciatica leads to poorer outcome. A systematic and critical review of literature revealed that long duration of preoperative leg pain lead to poor outcome for herniation of nucleus pulposus. Only a broad time frame (2-12 months) could be derived from the review of literature due to lack of high quality studies and variable and contrasting results of the existing studies. While surgery performed within six months was most commonly found to lead to good outcome of surgery, further studies are needed to prove this more conclusively. At this stage it is felt that time alone should not be the basis of recommending surgery and multiple other variables should be considered in a shared decision making process between the surgeon and the patient.

Comparison of early and late percutaneous endoscopic lumbar discectomy for lumbar disc herniation. Acta Neurochir (Wien) 2013; 155:1931-6. [PMID: 23975645 DOI: 10.1007/s00701-013-1828-4] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2013] [Accepted: 07/19/2013] [Indexed: 10/26/2022]
Abstract
BACKGROUND The optimal timing for percutaneous endoscopic lumbar discectomy (PELD) in cases of lumbar disc herniation (LDH) is debatable. This retrospective study sought to determine which category of PELD surgical intervention time resulted in greater improvement in clinical outcomes. METHODS We retrospectively reviewed the medical records of 145 patients who underwent PELD for single-level LDH. The patients were divided into three categories according to the duration of leg pain before surgery, the early and late group being symptomatic for ≤3 months and >3 months, ≤6 months and >6 months, ≤12 months and >12 months. Surgical time, blood loss, postoperative hospital stay, hospitalization cost, rates of reoperation due to surgical failure, Macnab criteria assessment, visual analogue scale (VAS) of back pain, leg pain and numbness, Japanese orthopedic association low back pain score (JOA) before and after surgery were compared. RESULTS No significant differences were found between the early and late groups according to different categories in patients' demographics, surgical time, blood loss, preoperative and postoperative VAS (lower-back pain, leg pain and numbness) scores, JOA scores and distribution of Macnab criteria assessment. Early PELD surgical intervention did not result in greater improvement of clinical outcomes. Later surgical intervention resulted in about one-third surgical failure rates for patients being symptomatic for >6 months (≤6 months, 11/96, 11.5 %; >6 months, 2/49, 4.1 %; P = 0.245) and >12 months (≤12 months, 12/120, 10.0 %; >12 months, 1/25, 4.0 %; P = 0.568) of the early surgical intervention groups. Significant difference was observed between the comorbidities and non-comorbidities group in the rate of reoperation (P = 0.040). CONCLUSIONS Early PELD surgical intervention did not result in greater improvement of clinical outcomes for patients with lumbar disc herniation. Later surgical intervention resulted in less failure rates for patients than the early surgical intervention groups. PELD performed when the leg pain before surgery being symptomatic for >6 months may be good for avoiding surgical failure and reducing the duration of leg pain.

Abstract
BACKGROUND Lumbar disc hernia (LDH) and lumbar spinal stenosis (LSS) are the most common diagnoses of low back and leg pain symptoms. The Japanese Orthopedic Association Back Pain Evaluation Questionnaire (JOABPEQ) is a measure of health-related quality of life in these patients. This study aimed to cross-culturally translate and validate the JOABPEQ in Iran. METHODS This was a prospective clinical validation study. The translation and cross-cultural adaptation of the original questionnaire was performed in accordance with published guidelines. A total of 103 patients with LDH or LSS were asked to respond to the questionnaire at two points in time: pre- and postoperative assessments (6 months follow-up). To test reliability, the internal consistency was assessed by Cronbach's alpha coefficient, and validity was assessed using convergent validity. Responsiveness to change was also assessed comparing patients' pre- and postoperative scores. RESULTS The Cronbach's alpha coefficients for the JOABPEQ at pre- and postoperative assessments ranged from 0.71 to 0.81, indicating a good internal consistency for the questionnaire. In addition, the correlation of each item with its hypothesized subscale of the JOABPEQ showed satisfactory results, suggesting that the items had a substantial association with the subscale representing the concept. Further analysis also indicated that the questionnaire was responsive to change (P < 0.0001). CONCLUSIONS In general, the Iranian version of JOABPEQ performed well, and the findings suggest that it is a reliable and valid measure of back pain evaluation among LDH and LCS patients.
