- Abstract
Two main causes of gastrocnemius contracture have been considered: 1) congenital deformities in pediatric patients, such as limb-length discrepancy, cerebral palsy, flatfoot, and clubfoot; and 2) secondary conditions such as immobilization for trauma or a nonfunctional limb. Talipes equinus deformity caused by fibrous gastrocnemius contracture after a direct muscle contusion is extremely rare. We describe 2 cases of talipes equinus deformity caused by fibrous gastrocnemius muscle contracture after a direct contusion in football players. Both of the players had a talipes equinus deformity with a severe restriction of ankle dorsiflexion, and a cord-like structure was observed at the proximal part of the lateral gastrocnemius head. Both patients' histological examinations revealed fibrous tendon-like tissue within the structure. After discission of the cord-like structures, the restriction of ankle dorsiflexion was completely resolved, and the patients were able to fully return to playing football without any discomfort in their calves.

Most chronic low back pain includes elements of nociceptive pain, neuropathic pain, and nonorganic pain. We conducted screening for nonorganic pain with use of the Brief Scale for Psychiatric Problems in Orthopaedic Patients (BS-POP), which is simple and can be used for multidimensional assessment. Research on pain areas using functional magnetic resonance imaging (fMRI) and positron emission tomography has shown that the dopamine system contributes to the pathology of chronic low back pain. Chronic low back pain patients show decreased activation of the anterior cingulate cortex, prefrontal cortex, and nucleus accumbens. Given that both the anterior cingulate cortex and prefrontal cortex belong to the descending inhibitory system, and that the nucleus accumbens, which is involved in the dopamine system, releases μ-opioids that act to relieve pain, decreased activation in these three brain regions may be related to decreased function of the descending inhibitory system. A pathological condition that can be explained at the molecular biological level clearly exists between chronic low back pain and psychosocial factors, and investigations of a pathological condition of chronic low back pain including brain function are needed.

- Abstract
Osteochondroma, one of the most common benign bone tumors, frequently occurs in the metaphysis of the long bones. We report an extremely rare case of osteochondroma that occurred in the tibial sesamoid. The patient was a 62-year-old Japanese male. He presented with a 1-year history of pain and a hard mass on the plantar aspect of the right forefoot sole. The osteochondroma protruded toward the sole from the tibial sesamoid, leading to pain on weightbearing. After tibial sesamoidectomy, the patient's symptoms were eliminated, and no pain or complications such as hallux valgus occurred after the surgery. Although a potential risk exists of postoperative hallux valgus deformity, tibial sesamoidectomy seems to be an appropriate surgical option for both osteochondroma and bizarre parosteal osteochondromatous proliferation to avoid residual pain or local recurrence.

Background: In 2007, the Japanese orthopaedic association back pain evaluation questionnaire (JOABPEQ) was established to overcome the limitations of the original JOA scoring system developed in 1986. Although this new self-administered questionnaire is a more accurate outcome measure for evaluating patients with low back pain, physicians were unable to as certain the exact status of a patient at a single time point because of a lack of reference values. This study aimed to establish the reference values of JOABPEQ in different age and gender groups using data obtained from healthy volunteers. Methods: This study was conducted in 21 university hospitals and affiliated hospitals from October 2012 to July 2013. The JOABPEQ includes 25 questions that yield five domains to evaluate individuals with low back pain from five different perspectives. A total of 1,456 healthy volunteers (719 men, 737 women; age range, 20-89 years) answered the questionnaire. The differences in scores according to age and gender were examined by non-parametric tests. Results: The JOABPEQ scores significantly decreased with age in the domains of lumbar spine dysfunction, gait disturbance, and social life dysfunction. In these three domains, the median scores approached the 100 possible points in individuals aged 20-70 for both genders. However, the median scores for lumbar spine dysfunction and social life dysfunction decreased to 83.0 and 65.0-78.0 points, respectively, in individuals in their 80 s and 70-80 s, respectively; and the scores for gait disturbance decreased to 93.0 and 71.0 points for males and females in their 80 s. Overall, the median scores for pain-related and psychological disorders were 100 and 60.0-72.0 points, respectively. Conclusion: The reference values for JOABPEQ according to age and gender were established herein. Patients with low back pain should be evaluated with this new self-administered questionnaire taking these reference values into account. [ABSTRACT FROM AUTHOR]

Background: An outcome measure to evaluate the neurological function of patients with cervical myelopathy was proposed by the Japanese Orthopaedic Association (JOA score) and has been widely used in Japan. However, the JOA score does not include patients' satisfaction, disability, handicaps, or general health, which can be affected by cervical myelopathy. In 2007, a new outcome measure, the Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire (JOACMEQ), which is a self-administered questionnaire, was developed. However, the influence of age and gender on the scores has not been fully examined. The purpose of this study was to establish the standard value of the JOACMEQ by age using healthy volunteers. Methods: This study was conducted in 23 university hospitals and their affiliated hospitals from September to December 2011. The questionnaire included 24 questions for evaluation of physical function of the cervical spine and spinal cord. A total of 1,629 healthy volunteers were recruited for the study. The ages ranged from 20 to 89 years old. Results: The volunteers comprised 798 men and 831 women. In the elderly healthy volunteers, the JOACMEQ scores decreased with age. In general, the scores for cervical spine function and upper/lower extremity function were retained up to the 60s, then decreased in the 70s and 80s. The scores for quality of life were retained up to the 70s; however, the score for bladder function was retained up to the 40s, then declined with age from the 50s to 80s. Conclusion: The standard values of the JOACMEQ by age were established. Differences in the scores were found among different generations. Patients with cervical myelopathy should be evaluated with this new self-administered questionnaire taking into account the standard values according to different ages. [ABSTRACT FROM AUTHOR]

Background data: There is a considerable difference in pain perception among individuals. In patients with chronic pain, recent studies using fMRI, PET and SPECT have shown that functional changes mainly occurred in the anterior cingulate cortex (ACC), prefrontal cortex (PFC) and thalamus. Brain magnetic resonance spectroscopy (MRS) can evaluate brain chemistry by measuring metabolites such as N-acetyl aspartate (NAA). The purpose of this study was to analyze whether brain MRS could assess pain due to lumbar spine diseases. Methods: NAA levels were determined relative to the concentration of creatine/phosphocreatine complex (Cr) and choline (Cho), which is commonly used as an internal standard. The NAA/Cr and NAA/Cho ratios in the ACC, PFC and thalamus were compared between six patients with unilateral pain (left side) and six control patients without pain. Results: In the right thalamus (contralateral side to symptom), the NAA/Cr in the patients with pain was statistically significantly lower compared with the control patients ( p < 0.05). Also, in the right thalamus, the NAA/Cho in pain patients was significantly lower compared with controls ( p < 0.01). When considering just the right thalamus, there were statistically significant correlations between the numerical rating scale for pain (NRS) and NAA values. Conclusions: Lumbar pain can be assessed indirectly by analyzing the decrease in NAA concentration in the thalamus. [ABSTRACT FROM AUTHOR]

- Abstract
Purpose: The purpose of this study was to clarify the mechanism of tendon regeneration by investigating macroscopically, histologically, and biomechanically. Methods: Fifty, adult, female Sprague-Dawley rats were used. The Achilles tendon in the left hind limb was removed totally by use of the tendon-stripping device. Rats were killed at 2, 7, 30, 90, and 180 days after surgery, and the regenerate tendons were dissected. Contralateral Achilles tendons were used as normal controls. Gross anatomic changes, microscopic remodeling, and recovery of biomechanical properties of regenerate tendons were investigated. The expressions of type I collagen, type III collagen, and transforming growth factor β1 were also investigated by immunohistochemistry. Results: The regenerate tendons formed in all specimens. In the early phase, hematoma and soft granulation tissue were observed at the harvest defect. These gradually matured with time, and the microscopic structure became quite similar to normal at 180 days after surgery. These findings occurred uniformly along the entire length of the regenerate tendon. However, the biomechanical properties were significantly inferior to the normal tendons (P < .05). Transforming growth factor β1 was well co-localized with inflammatory cells and fibroblasts in the regenerate tendons. The type I–type III collagen ratio in the regenerate tendon was significantly decreased in the early phase (P < .05) but gradually increased with time. Conclusions: Tendon regeneration and maturation occurred uniformly along the length of regenerate tendons. The hematoma that initially occupies the harvest defect acted as a scaffold for fibroblast precursor cells from the surrounding peritendinous tissue and tendon sheath. The mechanical properties of regenerate tendon were significantly inferior to contralateral control even at 180 days after surgery, and the alteration of the collagen composition would have an influence on mechanical properties of regenerate tendon. Clinical Relevance: Clinicians should be cautious about using reharvested hamstring tendons for ligament reconstruction surgery. [Copyright &y& Elsevier]

ANKLE brachial index , *TIBIAL arteries , *SPINAL stenosis , *PALPATION , *INTERMITTENT claudication , *MEDICAL screening - Abstract
The Japanese Society for Spine Surgery and Related Research previously developed a diagnostic support tool for lumbar spinal stenosis (LSS-DST). Using the LSS-DST, general physicians can identify potential cases of LSS. However, in the LSS-DST, measurement of the ankle brachial pressure index (ABI) is required to exclude peripheral artery lesions in the lower limbs. We can expect further application of the LSS-DST if we can identify a simpler and easier method than ABI measurement. Therefore, in this large-scale, multicenter, cross-sectional study, we verified whether palpation of the posterior tibial (PT) artery could be used instead of ABI in the LSS-DST. This survey was conducted at 2177 hospitals and included 28,883 participants. The sensitivity and specificity of the original LSS-DST method using the ABI and that of the LSS-DST ver2.0 with PT artery palpation were assessed to screen their ability for diagnosing LSS, using the physicians' final diagnosis based on the patients' history, physical examination and radiographic findings as the gold standard. The sensitivity and specificity [95%CI] of the LSS-DST were 88.2% [87.5, 88.8] and 83.9% [83.4, 84.5], respectively, whereas the sensitivity and specificity of the LSS-DST ver2.0 were 87.7% [87.0, 88.3] and 78.3% [77.7, 78.9], respectively, indicating that LSS-DST ver2.0 is a useful screening tool for LSS with good sensitivity. When the item of ABI in the LSS-DST is replaced by palpation of the PT artery (LSS-DST ver2.0), its sensitivity is maintained as a screening tool for LSS. Level 3. [ABSTRACT FROM AUTHOR]

Background: Reduced core stability is a potential risk factor for low back pain in athletes. However, the association between core stability and low back pain in high school baseball players has not been thoroughly studied. The purpose of this study was to investigate the relationship between core stability and low back pain and its clinical characteristics in high school baseball players.Methods: Participants comprised 812 high school baseball players who had undergone annual medical evaluations, comprising a self-completed questionnaire and a physical examination. We investigated the relationships between low back pain during the season and on the day of medical evaluations and core stability using a cross-sectional study design. Core stability was assessed using the Sahrmann core stability test.Results: Reduced core stability was confirmed in 358 (44.1%) of all players, 98 (49.5%) pitchers, and 260 (42.3%) fielders. In total, 352 players (43.3%) reported incidents of seasonal low back pain during the previous year. Thirty-five pitchers (17.7%) and 153 fielders (24.9%) reported low back pain on the day of the medical evaluations. No significant associations were seen between low back pain throughout the season and reduced core stability. After adjusting for confounding factors (total amount of practice per week, hamstring tightness and quadriceps tightness) using logistic regression modeling, a significant association between presence of low back pain during lumbar extension movement and reduced core stability was found (odds ratio, 2.57; 95% confidence interval, 1.08-6.62; P = 0.033) in pitchers.Conclusions: High school baseball pitchers with reduced core stability showed a higher probability of reporting low back pain during lumbar extension movement. Evaluation of core stability should be considered in high school baseball players, especially in pitchers. [ABSTRACT FROM AUTHOR]- Published

Background: Limited flexibility of the lower extremities, such as hamstring tightness, has long been suggested as a physical risk factor for low back pain among adolescent athletes. However, few prospective cohort studies have examined the direction of causality for this relationship. This prospective cohort study investigated the relationship between limited flexibility of the lower extremities and the occurrence of low back pain among high school baseball players.Methods: Participants comprised 335 high school baseball players from 43 high school baseball teams who had undergone baseline medical evaluations (a self-completed questionnaire and physical examination). Occurrence of low back pain during a 1-year follow up, and associations with measurements of flexibility of the lower extremities such as straight-leg-raising angle (hamstring tightness), Thomas test (iliopsoas tightness), heel-buttock-distance (quadriceps tightness), and passive range of motion of the hip were investigated.Results: In total, 296 players (88.4%) participated in the 1-year follow-up survey, with 147 of the 296 players (49.7%) reporting the occurrence of low back pain during follow-up. The number of players with low back pain during follow-up peaked in November, then decreased and was lowest in June. After adjusting for factors associated with low back pain using logistic regression modeling, a significant association between hamstring tightness on the non-throwing arm side and low back pain (odds ratio 2.86, 95% confidence interval 1.17-6.94; P = 0.018) was found.Conclusions: Hamstring tightness on the non-throwing arm side was identified as a potential risk factor for low back pain in high school baseball players. These results may provide guidance in the development of future prevention programs. [ABSTRACT FROM AUTHOR]- Published

Background: Sacroiliac joint (SIJ) dysfunction is a potential source of low back pain (LBP) in baseball players, who are more likely to be affected by loading of the SIJ in the throwing motion. However, the prevalence and characteristics of this condition have not been studied thoroughly. This study aimed to investigate the prevalence and clinical characteristics of SIJ dysfunction among high school baseball players.Methods: Participants comprised 891 high school baseball players who had undergone annual medical evaluations (a self-completed questionnaire and physical examination). The prevalence of SIJ dysfunction and associations with the measurements of the flexibility of the spine and lower extremities such as finger-floor-distance, straight-leg-raising angle, heel-buttock-distance, Thomas test, and passive range of motion of the hip were investigated.Results: Twenty-two of 891 subjects (2.5%) met our criteria for SIJ dysfunction. Twelve subjects (55%) exhibited throwing arm side symptoms more commonly than in the non-throwing arm side (n = 3, 15%) or bilateral side (n = 7, 32%). Previous episodes of LBP were experienced significantly more frequently among subjects with SIJ dysfunction (n = 19, 86.4%) than among those without (n = 501, 57.7%; P = 0.015). The prevalence of present LBP that interfered with play was significantly higher among subjects with SIJ dysfunction (n = 9, 42.9%) than among those without (n = 118, 21.2%; P = 0.038). The prevalence of SIJ dysfunction as a source of LBP was estimated at 7.1% (9 of 127 subjects). After adjustment for associated factors using a logistic regression model, we observed a significant association between a limitation in hip internal rotation on the throwing arm side and SIJ dysfunction (odds ratio 3.11 [1.30-7.71]; P = 0.0109).Conclusions: According to our criteria, the estimated prevalence of SIJ dysfunction among high school baseball players is 2.5%. There was a significant association between a limitation in hip internal rotation on the throwing arm side and SIJ dysfunction. [ABSTRACT FROM AUTHOR]- Published

Background: Deterioration of quality of life in patients with chronic pain is difficult to treat. Chronic pain in patients with low quality of life may be "severe" and require multidisciplinary treatments. This study aimed to develop an objective severity discrimination scale based on quality of life measurements to identify patients with "severely disabling" chronic pain.Methods: Subjects were 156 patients with chronic pain whose numerical rating pain score was ≥1 and who had pain for ≥3 months. Diseases associated with chronic pain included spinal diseases, joint diseases, concomitant diseases, complex regional pain syndromes, and other musculoskeletal diseases. Patients were divided into low, middle, and high groups based on physical quality of life summary scores on the Short Form-36. The mental component summary, painDETECT, Japanese version of the Pain Catastrophizing Scale, Brief Scale for Psychiatric Problems in Orthopaedic Patients, and factors related to degree/quality of pain during the past 4 weeks were analyzed to identify components in the low group. The score weighting factor for discriminating between the high and low groups was determined by discriminant analysis.Results: Factor analysis identified 4 factors representing features of chronic pain patients with low QOL: enhanced perception of pain, pain catastrophic thoughts, depressive sleep disorder, and pain intensity. For discriminant analysis, patients were defined as those with low physical quality of life if each factor's total score multiplied by a factor plus a constant value of 2.6 was ≥0, and high quality of life if it was <0. The receiver operating characteristic curve area used to determine the cut-off value was 0.71, with 67.3% sensitivity and specificity.Conclusions: We developed a 33-question severity discrimination scale to define "severely disabling" chronic pain based on physical quality of life. "Severely disabling" patients identified on this scale could represent chronic pain patients needing focused multidisciplinary treatment. [ABSTRACT FROM AUTHOR]- Published

Background: The reference values of the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) in patients with lumbar spinal stenosis (LSS) are still unknown. This multicenter cross-sectional survey was performed to determine the reference values and disease-specific characteristics of deterioration of QOL caused by LSS itself, not by aging, through comparison of patients with and without LSS who had an outpatient visit for low back pain by age and sex groups.Methods: The present study was performed at 564 medical centers and clinics. The JOABPEQ was measured for 8338 patients aged 20 years or over who came to an outpatient clinic for low back pain (LBP) and were examined for whether they had LSS using the LSS diagnosis support tool (LSS-DST). Scores in the five JOABPEQ domains were compared between the LSS group and the LBP without LSS group (LBP group) for each age and sex group.Results: Scores for Pain-related disorder, Gait disturbance, Social life disturbance, and Psychological disorders were significantly lower in the LSS group than in the LBP group.Conclusion: The percentiles of JOABPEQ scores in patients with LSS were clarified and could be used as reference values. Deterioration of QOL caused by LSS itself, not by aging, are characterized by Pain-related disorder, Gait disturbance, Social life disturbance, and Psychological disorders.

Background: In 1999, the Japanese Orthopaedic Association decided to develop a new Cervical Myelopathy Evaluation Questionnaire (JOACMEQ). The final version of the JOACMEQ, comprising 24 questions and five domains (cervical spine function (CF); upper extremity function (UF); lower extremity function (LF); bladder function (BF); and quality of life (QOL)), was established after three nationwide investigations. The fourth investigation, reported in this paper, was performed to confirm the responsiveness of the questionnaire.Methods: A total of 137 patients with cervical myelopathy were included in the study. Each patient was interviewed twice using the JOACMEQ before and after treatment. At the second interview, the patients self-rated their condition in five domains for "worse," "somewhat worse," "no change," "somewhat better," or "better," and these scores were defined as the external assessment rating. The difference of the points in five domains between the first and the second interview was calculated against each external assessment. Based on the results, substantial clinical benefit (SCB) thresholds for the JOACMEQ were determined.Results: The statistically significant median values of the acquired points were 17.5 for CF, 16.0 and 21.0 for UF, 27.0 and 20.5 for LF, 13.0 for BF, and 29.0 for QOL. After consideration of the results, the committee decided that an acquired point ≥20 could be interpreted as representing an SCB threshold for the JOACMEQ.Conclusion: We have concluded that a treatment can be judged to be effective for a patient if 1) The patient give all answers for the questions necessary to calculate the functional score of a domain and an increase of ≥20 points is obtained for that score, or 2) The functional score after treatment is > 90 points even if the answer for the unanswered questions was supposed to be the worst possible choice.

Background The Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) was developed in 2007, including the five domains of Pain-related disorder, Lumbar spine dysfunction, Gait disturbance, Social life disturbance, and Psychological disorder. It is used by physicians to evaluate treatment efficacy by comparing scores before and after treatment. However, the JOABPEQ does not allow evaluation of the severity of a patient's condition compared to the general population at a single time point. Given the unavailability of a standard measurement of back pain, we sought to establish reference scores and interquartile ranges using data obtained from a multicenter, cross-sectional survey taken in Japanese primary care settings. Methods The Lumbar Spinal Stenosis Diagnosis Support Tool project was conducted from 2011 to 2012 in 1657 hospitals in Japan to investigate the establishment of reference scores using JOABPEQ. Patients aged ≥ 20 years undergoing medical examinations by either non-orthopaedic primary care physicians or general orthopedists were considered for enrollment. Results A total of 10,651 consecutive low back pain patients (5331 men, 5320 women, 18 subjects with missing sex data) who had undergone a medical examination were included. Reference scores and interquartile ranges for each of the five domains of the JOABPEQ according to age and sex were recorded. The median score and interquartile range are the same in the domain of Pain-related disorder in all ages and sexes. The reference scores for Gait disturbance, Social life disturbance and Psychological disorder declined with increasing age in both age- and sex-stratified groups, while there was some different trend in Lumbar spine dysfunction between men and women. Conclusion Reference scores and interquartile ranges for JOABPEQ were generated based on the data from the examination data. These provide a measurement standard to assess patient perceptions of low back pain at any time point during evaluation or therapy. [ABSTRACT FROM AUTHOR]

Background: Numbness in the soles of both feet at rest or bowel/bladder dysfunction can occur in patients with lumbar spinal stenosis (LSS), especially in patients with cauda equina lesions. The purpose of this study was to clarify the relationship between cauda equina symptoms at rest and quality of life (QOL) in LSS patients using standardized questionnaires developed for the Japanese population.Methods: A survey was conducted in 564 hospitals and general practice clinics nationwide from December 1, 2011 to December 31, 2012. All patients who visited hospital or clinic because of low back pain were included. Patients were diagnosed with LSS using the LSS-Diagnostic Support Tool (LSS-DST), and the severity of the disease was measured using the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) for quality of life. Presence of both sole numbness and/or bowel/bladder dysfunction were determined by medical interview. 3647 patients were diagnosed with LSS according to the results of the LSS-DST. 1294 of these patients (35.5%) had symptoms at rest. Of these patients, 359 patients with sole numbness, 135 patients with bowel/bladder dysfunction, and 52 patients with both numbness and bowel/bladder dysfunction were compared to the patients without rest symptoms (n = 2182). Comparisons between groups with or without sole numbness and bowel/bladder dysfunction were performed using statistical analysis of JOABPEQ responses in the categories of pain-related disorder, lumbar spine disorder, gait disturbance, social life disturbance, and psychological disorder.Results: All groups with sole numbness and/or bowel/bladder dysfunction had statistically lower (worse) scores in all categories of the JOABPEQ compared to the group without these symptoms at rest.Conclusion: LSS patients having numbness in the soles of both feet at rest or bowel/bladder dysfunction had lower measurements of QOL and activities of daily living than those patients without symptoms at rest. These symptoms appear to be related to QOL of LSS patients. [ABSTRACT FROM AUTHOR]- Published

Background: There are no diagnostic support tools composed of a simple, single-sheet, self-administered, self-reported history questionnaire (SSHQ) for patients with leg symptoms caused by either lumbar spinal stenosis (LSS) or lumbar disc herniation (LDH), at the same time, can discriminate the two diseases.Methods: We conducted retrospective and prospective derivation studies and a prospective validation study. Based on data from 137 patients with LSS and 206 with LDH, we identified key prediction factors to establish the diagnosis of LSS and LDH, which became the basis of a temporary SSHQ. Next, we performed a prospective derivation study in which 296 patients with LSS or LDH completed preoperatively this temporary SSHQ. After univariate and multivariate analyses of each question, questions on both diseases in addition to age factor were selected, providing the final version of the SSHQ. A validation study was subsequently performed with 342 consecutive patients with leg symptoms. The sensitivity, specificity and likelihood ratio of this SSHQ were calculated to determine the cut-off points for LSS and LDH.Results: A SSHQ with 15 questions was developed from retrospective and prospective derivation studies. The score of each question was weighted based on the multivariate analysis and then, it was approximated to integer value. According to assessment of the discriminatory performance of the clinical prediction rule of the SSHQ, the cut-off point for LSS was ≥13 and that for LDH was ≥11. The sensitivity, specificity, and positive and negative likelihood ratios of this SSHQ at those cut-off points were, respectively, 92.7%, 84.7%, 6.07, and 0.09 for LSS, and 91.0%, 85.2%, 6.15, and 0.11 for LDH.Conclusions: This is the first report of a diagnostic support tool for patients with LSS- or LDH-induced leg symptoms combined in a single SSHQ that could help establish diagnosis of the two diseases in the daily clinical practice.

Background: Diagnostic support tools for lumbar spinal stenosis such as the Self-administered, Self-reported History Questionnaire have been developed in Japan, but no report has demonstrated the diagnostic accuracy of this questionnaire in Japanese primary care settings. This multicenter, cross-sectional survey was performed to evaluate and improve the diagnostic accuracy of this questionnaire for lumbar spinal stenosis patients in Japanese primary care settings.Methods: The lumbar spinal stenosis diagnosis support tool project was conducted in 1657 hospitals to evaluate the diagnostic accuracy of the Self-administered, Self-reported History Questionnaire in Japan from 2011 to 2012. Consecutive adults (≥50 years old) from physicians, including non-orthopedic general practitioners and orthopedic general practitioners, were considered for enrollment. Consecutive adults (≥50 years old) with low back pain from hospital-based orthopedic surgeons were also considered for enrollment. The diagnostic accuracy of the Self-administered, Self-reported History Questionnaire with initial and several new cutoff points in classifying patients according to the presence of lumbar spinal stenosis was assessed in terms of sensitivity, specificity and negative predictive values.Results: Among the 33,545 patients, 10,199 (30.4 %) were diagnosed with lumbar spinal stenosis by the physicians. The Self-administered, Self-reported History Questionnaire version 1.1 with a new cutoff point was more sensitive than the Self-administered, Self-reported History Questionnaire version 1.0 with the initial cutoff point (79.8 vs. 68.3 %) and less specific (68.8 vs. 75.1 %) for lumbar spinal stenosis diagnosis. The respective negative predictive values were 88.5 and 84.3 %.Conclusions: The Self-administered, Self-reported History Questionnaire version 1.1 with the new cutoff was more sensitive and had higher negative predictive value than version 1.0 with the initial cutoff. Therefore, the improved Self-administered, Self-reported History Questionnaire version 1.1 can be used for lumbar spinal stenosis screening, and its use may improve the quality of lumbar spinal stenosis diagnostic practice in Japanese primary care settings.

Background: We developed the Brief Scale for Psychiatric Problems in Orthopaedic Patients (BS-POP, physician and patient versions) and have previously shown that the BS-POP is reliable and has construct validity, criterion validity, and reproducibility. The present study aimed to proactively verify the responsiveness of the BS-POP with regard to chronic low back pain (LBP) patients. Methods: The study subjects included 193 chronic LBP patients (81 males, 112 females; mean age 62 years) who had suffered from persistent LBP for ≥3 months. During the first test (before the treatment), the BS-POP, the Minnesota Multiphasic Personality Inventory (MMPI), the Profile of Mood States (POMS), the 36-item Short-form Health Survey version 2 (SF-36 v2), and the Roland-Morris Disability Questionnaire (RDQ) were conducted. The BS-POP, POMS, SF-36 v2, and RDQ for the third test were conducted (4-6 weeks after treatment) on all patients who had participated in the first test to determine the responsiveness of the BS-POP. The responsiveness of the BS-POP was investigated statistically. Results: The total crude BS-POP scores were significantly lower for both physician and patient versions in the third test than in the first test. Moreover, the crude RDQ scores and SF-36 v2 items, physical functioning (PF), bodily pain (BP), MH, VT, and GH, and POMS items, tension-anxiety (T-A), D, F, and confusion (C) improved significantly, confirming responsiveness to treatment. Discussion: The present findings indicate that the BS-POP possesses sufficient responsiveness from a computational psychology perspective. The BS-POP constitutes a tool enabling orthopaedists to easily identify psychiatric problems in orthopaedic patients. [ABSTRACT FROM AUTHOR]

Background: Pregabalin is a well-accepted treatment option for patients with neuropathic pain. However, the therapeutic efficacy of pregabalin for reducing the incidence of spinal surgery to treat leg symptoms in patients with lumbar spinal stenosis remains unknown. The purpose of this study was to analyze the therapeutic efficacy of pregabalin for reducing the incidence of spinal surgery for leg symptoms in patients with lumbar spinal stenosis during the first year of treatment. Methods: Consecutive patients diagnosed with lumbar spinal stenosis at our hospital from January to June 2009 were treated with nonsteroidal anti-inflammatory drug monotherapy and formed the control group ( n = 47; 22 males, 25 females). Patients diagnosed with lumbar spinal stenosis at our hospital between August 2010 and October 2011 were treated with a nonsteroidal anti-inflammatory drug and pregabalin combination therapy and formed the pregabalin group ( n = 49; 27 males, 22 females). The proportions of patients who underwent spinal surgery during the first year of treatment were assessed and compared between the two groups using the Mann-Whitney U test. In addition, the periods in which patients decided to undergo spinal surgery were compared using the Kaplan-Meier method. Results: Six patients (12.2 %) in the pregabalin group and 22 patients (46.8 %) in the control group underwent spinal surgery during the first year of treatment ( P = 0.0035). The period in which patients decided to undergo spinal surgery was significantly delayed in the pregabalin group compared with the control group in those for whom spinal surgery was necessary ( P = 0.0128). Conclusions: Nonsteroidal anti-inflammatory drug and pregabalin combination therapy may result in a lower incidence of spinal surgery during the first year of treatment or a delayed period before undergoing spinal surgery if necessary compared with nonsteroidal anti-inflammatory drug monotherapy in patients with leg symptoms caused by lumbar spinal stenosis.

Abstract: Objectives: While several studies have cited a potential association between testosterone deficiency and risk of falls among community-dwelling older men, evidence for such an association is conflicting. Depressive symptoms, which occasionally accompany testosterone deficiency but which are often neglected as associated symptoms, may actually provoke falls independent of or jointly with testosterone deficiency. We examined the association between testosterone levels, depressive symptoms, and falls, and assessed the joint effect of testosterone levels and depressive symptoms on falls among older men. Design, Setting, and Participants: Data for this cross-sectional study were obtained from 869 men aged over 60 years who participated in health check-ups conducted in 2010 from 2 Japanese municipalities. Salivary testosterone (sT) levels were measured using an enzyme-linked immunosorbent assay, and depressive symptoms were assessed via the short form of the Center for Epidemiologic Studies Depression Scale. Main outcome measures: Self-reported “any fall” over the 1-month period. Results: Among the total of 482 participants analyzed (median age, 70 years), 10.8% reported any fall. On comparison between 90th percentile sT levels and lower levels, our logistic regression model with restricted cubic splines showed that lower sT levels were associated with an increased likelihood of suffering any fall after adjustment for sociodemographic characteristics, comorbidities, and mobility function. For example, 5th percentile sT was associated with any fall [adjusted odds ratio (OR), 4.23; 95% confidence interval (CI), 1.66–10.8]. Depressive symptoms were also strongly associated with any fall [adjusted OR, 3.49 (95% CI, 1.52–8.04)]. We noted no apparent interaction of sT and depressive symptoms with falls (P = .079), suggesting that the joint effect of testosterone deficiency and depressive symptoms on falls was multiplicative. Indeed, compared with a combination of 90th percentile sT values and no depressive symptoms, adjusted OR for any fall in a combination involving 5th percentile sT and depressive symptoms was 14.8-fold (95% CI, 3.76–58.0). Conclusions: Our findings indicated that both relatively low testosterone levels and presence of depressive symptoms were independently associated with falls among older men. Causality of these associations should be confirmed in future prospective studies. [Copyright &y& Elsevier]

Background: Few studies have examined the prevalence of lumbar spinal stenosis (LSS) in the general population. The purposes of this study were to estimate the prevalence of LSS and to investigate correlated factors for LSS in Japan. Methods: A questionnaire survey was performed on 4,400 subjects selected from residents aged 40–79 years in Japan by stratified two-stage random sampling in 2010. The question items consisted of lower-limb symptoms suggestive of LSS, the diagnostic support tool for LSS (LSS-DST), demographic and lifestyle characteristics, comorbidities, the Japanese Perceived Stress Scale (JPSS), and the Mental Health Index 5 (MHI-5). Using the LSS-DST, the presence of LSS was predicted to estimate the prevalence of LSS. Logistic regression analysis was performed to examine the relationship between LSS and correlated factors. Results: Questionnaires were obtained from 2,666 subjects (60.6 %), consisting of 1,264 males (47.4 %). The mean (standard deviation) age was 60.0 (10.9) years. According to the LSS-DST, 153 subjects were regarded as having LSS. The prevalence was estimated to be 5.7 %. When standardizing this value with the age distribution of the Japanese population, it was estimated that 3,650,000 Japanese subjects aged 40–79 years might have LSS using the LSS-DST. Prevalence increased with age and was particularly high in subjects aged 70–79 years, irrespective of gender. As correlated factors, an advanced age (60 years or older), diabetes mellitus, urological disorders, and osteoarthritis/fracture as comorbidities, and depressive symptoms, were associated with LSS. Conclusions: This study elucidated the prevalence of LSS and factors associated with LSS in Japan. This is the first report describing the estimated prevalence of LSS and associated factors using a strictly sampled representative population. [ABSTRACT FROM AUTHOR]

INTERMITTENT claudication , *SPINAL stenosis , *ARTERIAL diseases , *OLDER people , *DISEASE prevalence , *SCIENTIFIC observation - Abstract
Background: Intermittent claudication is a common symptom of both lumbar spinal stenosis (LSS) and peripheral arterial disease (PAD) in middle-aged and elderly people. However, the prevalence and clinical characteristics of LSS with PAD (LSSPAD) have not been investigated in a multicenter study. The aim of this study was to investigate the prevalence and clinical characteristics of LSS associated with PAD. Methods: 570 patients diagnosed with LSS using a clinical diagnostic support tool and MRI at 64 facilities were enrolled. We evaluated each patient's medical history, physical findings, ankle brachial index, Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) score, and the Short Form 36 (SF-36) score. Statistical analyses were performed to compare LSSPAD patients and LSS patients without PAD using the t test, Mann-Whitney's U test, and multivariate recurrence analysis. p values of <0.05 were considered statistically significant. Results: The LSSPAD group comprised 38 patients (6.7 %); 20 (3.5 %) had pre-diagnosised PAD while 18 (3.2 %) had undetected PAD. The clinical characteristics of these patients were advanced age, diabetes, and a history of ischemic heart disease and cerebrovascular disorder. 570 patients enrolled, and 448 (78.6 %) of those patients were followed up at three months after enrollment. Pain in buttocks and legs improved less in the LSSPAD group than in the LSS group ( p < 0.05). Improvements in the 'general health' score in SF-36 were lower in the LSSPAD group than in the LSS group ( p < 0.05). Conclusions: Advanced age, diabetes, and a history of cerebrovascular disorder and ischemic heart disease were associated with LSSPAD. Because LSSPAD patients show less improvement in QOL than patients with LSS but without PAD do, clinicians should consider the coexistence of PAD in LSS patients. [ABSTRACT FROM AUTHOR]

Background: There is little evidence regarding long-term outcomes of locomotor dysfunction such as cardiovascular events, quality of life, and death. We are conducting a prospective cohort study to evaluate risk of cardiovascular disease, quality of life, medical costs, and mortality attributable to locomotor dysfunction. The present study determined baseline characteristics of participants in the Locomotive Syndrome and Health Outcome in Aizu Cohort Study (LOHAS). Methods: Cohort participants were recruited from residents between 40 and 80 years old who received regular health check-ups conducted by local government each year between 2008 and 2010 in Minami-Aizu Town and Tadami Town in Fukushima Prefecture, Japan. Musculoskeletal examination included assessment of physical examination of the cervical and lumbar spine, and upper and lower extremities and of physical function, such as grasping power, one-leg standing time, and time for the 3-m timed up-and-go test. Cardiovascular risk factors, including blood pressure and biological parameters, were measured at annual health check-ups. We also conducted a self-administered questionnaire survey. Results: LOHAS participants comprised 1,289 men (mean age 65.7 years) and 1,954 women (mean age 66.2 years) at the first year. The proportion of obese individuals (body mass index 25.0 kg/m) was 31.9% in men and 34.3% in women, and 41.0% of participants reported being followed up for hypertension, 7.0% for diabetes, and 43.6% for hypercholesterolemia. Prevalence of lumbar spinal stenosis was 10.7% in men and 12.9% in women, while prevalence of low back pain was 15.8% in men and 17.6% in women. Conclusion: The LOHAS is a novel population-based prospective cohort study that will provide an opportunity to estimate the risk of cardiovascular disease, quality of life, medical costs, and mortality attributable to locomotor dysfunction, and to provide the epidemiological information required to develop policies for detection of locomotor dysfunction.

Background: Until recently, no Japanese versions have existed of the more popular, patient-reported disability questionnaires for neck pain. This study aimed to test the reliability, validity, and responsiveness of the Japanese version of the Neck Pain and Disability Scale (NPDS), one of the most widely used questionnaires in patients with neck pain. Methods: In this validation study, 167 outpatients with neck pain participated. Patients received the NPDS and the Medical Outcome Study Short Form 36-item Health Survey (SF-36), and used Visual Analog Scales (VASs) to assess pain and global health. To examine test-retest reliability, patients who were considered stable by clinicians were given the NPDS 2 weeks after baseline. To examine responsiveness, patients who had not undergone treatment at the time of the first data collection or had no change in treatment over 3 months were studied again 2 weeks after starting a new medication or physical therapy. Results: Of the 167 participants, 143 completed the questionnaires (85.6%). Factor analysis showed two factors, defined as neck-pain-related disability (factor 1) and neck-related pain (factor 2). Cronbach's α coefficient for factor 1, factor 2, and total score was 0.94, 0.93, and 0.96. The intra-class correlation coefficients for the 19 more stable patients were 0.79, 0.88, and 0.87. For concurrent validity, the correlation between NPDS subscales and total score and SF-36 subscale scores ranged from r = −0.54 to −0.22 ( p < 0.01). Correlations between the NPDS subscales and total score and VAS of pain ranged from 0.56 to 0.77 ( p < 0.01) and those for VAS of global health ranged from 0.48 to 0.63 ( p < 0.01). The NPDS subscales and total scores of the 41 patients retested after treatment were significantly improved. Conclusions: The Japanese version of the NPDS is a useful scale with reliability, validity, and responsiveness in assessing patients suffering from neck pain. [ABSTRACT FROM AUTHOR]

Introduction: We developed the Brief Scale for Psychiatric problems in Orthopaedic Patients (BS-POP) (doctor and patient versions). The present study aimed to proactively verify the factorial validity, internal consistency, criterion-related validity and reproducibility of the BS-POP with regard to chronic low back pain patients. Methods: Subjects comprised 193 chronic low back pain patients. During the first test, the BS-POP, Minnesota Multiphasic Personality Inventory (MMPI), Profile of Mood States (POMS) and 36-Item Short-Form Health Survey version 2 (SF-36 v2) were conducted. In the second test, patients were asked to complete the BS-POP in order to verify BS-POP reproducibility. Results: Factor analysis demonstrated the factorial validity of the BS-POP, including 1-factor structure. Internal consistency was confirmed by Cronbach's α reliability coefficients of 0.794 (doctor version) and 0.750 (patient version). Criterion-related validity was confirmed through association with the psychosocial factors of the SF-36, the MMPI, and the POMS. The correlation coefficients for the retests were r = 0.654 (doctor version) and r = 0.719 (patient version), showing reproducibility. Discussion: The present findings indicate that the BS-POP possesses sufficient reliability regarding computational psychology. The BS-POP constitutes a tool enabling orthopaedists themselves to easily identify psychiatric problems in orthopaedic patients. Further study is required regarding responsiveness.

Objectives Findings from several experimental studies in animals have suggested a protective action of testosterone on kidney function, but hard evidence for such an association in humans is scarce. We examined the association between testosterone levels and kidney function among adult men living in super-aged communities. Design, setting, participants, and measurements We conducted cross-sectional study involving residents aged 40–80 years who participated in annual health check-ups in 2 communities. A total of 1031 men were recruited in 2010. Main exposure was salivary testosterone (sT) levels measured using an enzyme-linked immunosorbent assay. Main outcome was estimated glomerular filtration rate (eGFR) determined by age, gender, and serum creatinine levels. Results For the 848 participants analyzed, median age and eGFR were 69 years and 69.1 mL/min/1.73 m 2 , respectively. On comparison of 90th-percentile sT levels with lower levels, our general linear model with restricted cubic splines showed that lower sT levels were associated with decreased eGFR after adjustment for sociodemographic characteristics, comorbidities, and blood pressure. For example, fifth percentile sT was associated with decreased eGFR, with a difference in eGFR [−3.43 mL/min/1.73 m 2 (95% confidence interval, CI −6.02 to −0.84)] comparable in magnitude to the reduction in eGFR observed for a 6-year increase in age in our population. The association between low testosterone levels and decreased eGFR remained similar even when analyses were restricted to participants aged over 60 years (734 participants, median age 71 years). Conclusions Results from our study indicated that having low testosterone levels was independently associated with reduced eGFR in adult men. Our finding of this association between low testosterone levels and reduced kidney function needs to be corroborated among persons with chronic kidney disease or in a longitudinal study.
