Objectives: Treatment-seeking behaviour, evaluation and management approach, as well as responsiveness to management by individuals with knee osteoarthritis (OA) could be hampered by variations of common confounding (constant) factors of knee OA; age and sex. Studies that integrate age and sex variations in clinical factors such as pain intensity and physical function are limited. The aim of this study was to determine age and sex variations in pain intensity and physical function among individuals with knee OA in Nigeria. Design/setting/participants/outcome measures: Eightynine consecutively sampled patients diagnosed with knee OA from three selected public (secondary and tertiary) hospitals in Enugu, South-East Nigeria, participated in this cross-sectional survey. Instruments used were Visual Analogue Scale (VAS) and Ibadan Knee or Hip Osteoarthritis Measure (IKHOAM). Data were analysed using Analysis of Variance (ANOVA) and Students’-test with Bonferroni correction. The level of significance was set at 0.05. Results: Significant variations of age in pain intensity between age groups of 20-39 and each of 40-59 years (MD = -3.68, p = 0.01) and 60-79 years (MD = -3.23, p = 0.04) as well as physical function between age groups of 60-79 and each of 20-39 years (MD = 20.85, p = 0.02) and 40-59 years (MD = 10.70, p = 0.03) were observed. There was a significant sex variation in physical function, (F = 9.57, p < 0.05) but not in pain intensity (F = 2.91, p = 0.09) on oneway ANOVA, with females reporting higher scores on pain intensity (5.29 ± 2.97) and lower scores on physical function (64.06 ± 17.26) than males (3.94 ± 2.29 and 78.77 ± 17.08 respectively). Conclusions: Age and sex should be considered by clinicians in management programs for knee OA to address the specific needs of each individual patient.
目的:膝关节骨关节炎(OA)患者寻求治疗的行为，评估和管理方法，以及对管理的反应性可能受到膝关节OA常见混杂(恒定)因素变化的阻碍;年龄和性别。将临床因素如疼痛强度和身体功能的年龄和性别差异结合起来的研究是有限的。本研究的目的是确定尼日利亚膝关节OA患者疼痛强度和身体功能的年龄和性别差异。设计/环境/参与者/结果测量:从尼日利亚东南部埃努古选定的三家公立(二级和三级)医院连续抽样89名诊断为膝关节OA的患者参加了这项横断面调查。采用视觉模拟量表(VAS)和伊巴丹膝关节或髋关节骨关节炎量表(IKHOAM)。数据分析采用方差分析(ANOVA)和Bonferroni校正的学生检验。显著性水平设为0.05。结果:20 ~ 39岁与40 ~ 59岁各疼痛强度(MD = -3.68, p = 0.01)、60 ~ 79岁各疼痛强度(MD = -3.23, p = 0.04)、60 ~ 79岁与20 ~ 39岁各疼痛强度(MD = 20.85, p = 0.02)、40 ~ 59岁各疼痛强度(MD = 10.70, p = 0.03)的年龄差异均有统计学意义。单因素方差分析显示，生理功能的性别差异有统计学意义(F = 9.57, p < 0.05)，但疼痛强度的性别差异无统计学意义(F = 2.91, p = 0.09)，女性的疼痛强度得分(5.29±2.97)高于男性(3.94±2.29)，生理功能得分(64.06±17.26)低于男性(78.77±17.08)。结论:临床医生在膝关节OA管理方案中应考虑年龄和性别，以满足每位患者的具体需求。

Peripheral nerve repair is a major challenge in clinical practice. Nerve grafting is required to treat severe peripheral nerve defects caused by injuries. Available nerve sources for autologous transplantation are limited. Stem cells offer promise for peripheral nerve repair and regeneration. However, the current lack of Schwann cell phenotype, high costs, and major trauma limit the production of Schwann cells from stem cell differentiation. Thus, the purpose of this study is to investigate the ability of adipose-derived stem cells (ADSCs) to differentiate into the Schwann cell phenotype, after treatment with Schwann cell-derived neurotrophic factor (SDNF) in vitro. ADSCs were isolated and cultured for use in two types of nerve grafts: Acellular allogeneic nerves (ACEN), and acellular allogeneic nerves treated with SDNF (ACEN + SDNF). Chemically extracted, untreated acellular allogeneic nerves (CEN), acellular allogeneic nerves with isolated and cultured autologous SCs (CEN + SCs), and fresh autografts (AG) served as controls. Hematoxylin and eosin (HE) and S100 immunohistochemical staining were performed to observe the cytokine levels in the nerve grafts; enzyme-linked immunosorbent assay (ELISA) and realtime PCR were performed to evaluate the S100 and glial fibrillary acidic protein (GFAP) expression. The acellular nerve allografts seeded with ADSCs and SDNF showed significant S100 and GFAP expressions. No significant statistical differences were observed between the ACEN + SDNF, ACEN + SCs, and AG groups. These data suggest that such acellular nerve allografts should be evaluated as therapeutic strategies for treating severe peripheral nerve defects.

The etiology of pediatric idiopathic scoliosis remains poorly understood and it is likely that there is a combination of different factors responsible for its initiation and development. Although the literature highlights the importance of mechanical factors on spinal deformations, the concepts did not receive the attention and consideration they deserve. The Cobb angle is the gold standard value to assess the extent of spinal deformations and risk of progression. However from a biomechanical perspective, it is not the Cobb angle that prevails but rather the distance from the vertebrae to the axis of an ideal straight vertical spine that is well seated and centered on the sacrum. These vertebral offsets along with asymmetrical loads are responsible for additional bending forces that may reach much higher values than the compression forces of a symmetric same load on a straight spine. Forces can be modified, amplified and redistributed by the shape of the spine alone. This article is a review of biomechanics concepts that are applied to the spine with simple concrete examples, and is addressed to clinicians and practitioners in orthopaedics, physical therapy, and sport and exercise science.

Background: Automobile technicians in resource-limited countries depend more on manual than mechanized approach in their work, and as such, may be at high risk for musculoskeletal disorders such as low back pain (LBP). This study was aimed to investigate the prevalence, risk factors and health care service utilization for LBP among Nigerian automobile technicians. Methods: A total of 240 members of the National Association of Automobile Technicians responded in this survey. A previously validated instrument on prevalence, risk factors and health-care-service utilization for LBP was adapted in this study. Data was analysed using descriptive and interferential statistics. Alpha level was set at p < 0.05. Results: Twelve-month and point prevalence of LBP were 79.2% and 75%. On-going LBP was associated with work-related poor posture (46.7%), trauma (13.9%) and lifting of loads (11.7%). LBP mostly led to absenteeism from work (46.8%) and consultation with health practitioners (73.7%). 40% of respondents agreed to have incurred about N1000-N5000 as treatment cost, and 38.7% of the respondents lost about N5000-N10000 as estimated cost in terms of lost hours. Type of automobile activity engaged in (p = 0.483), frequent bending (p = 0.217), lifting objects weighing up to 5 kg (p = 0.071) or up to 25 kg (p = 0.719) and sustained sitting (p = 0.349) or standing (p = 0.996) were not significantly associated with prevalence of LBP. In the bivariate analysis, age (χ2 = 3.298, P = 0.192), marital status (χ2 = 0.098, P = 0.754), type of automobile repairs engaged in (χ2 = 0.493, P = 0.483), lifting objects up to 5 kg (χ2 = 3.269, p = 0.071), lifting objects up to 25 kg (χ2 = 0.130, p = 0.719), sustained sitting (χ2 = 0.840, p = 0.349), and sustained standing (χ2 = 0.002, p = 0.996) were not significantly associated with prevalence of LBP. Level of education (χ2 = 6.121, p = 0.047) was, however, associated with LBP prevalence, although this association was not sustained following logistic regression. Conclusion: There is a high prevalence of LBP among Nigerian automobile technicians, and it results in work absenteeism, economic burden and increased need to seek health care.
背景:在资源有限的国家，汽车技术人员在工作中更多地依赖于手工而不是机械化的方法，因此，他们患肌肉骨骼疾病如腰痛(LBP)的风险很高。本研究旨在探讨奈及利亚汽车技师腰痛的患病率、危险因素及医疗保健服务的使用情况。方法:对全国汽车技师协会的240名会员进行问卷调查。本研究采用了先前验证的关于腰痛患病率、风险因素和卫生保健服务利用情况的工具。数据分析采用描述性和干涉性统计。α水平设为p < 0.05。结果:腰痛12个月和点患病率分别为79.2%和75%。持续的腰痛与工作相关的不良姿势(46.7%)、创伤(13.9%)和举重(11.7%)有关。腰痛的主要原因是旷工(46.8%)和咨询医生(73.7%)。40%的受访者同意支付了约1000- 5000奈拉的治疗费用，38.7%的受访者损失了约5000- 10000奈拉的估计费用(以损失的时间计算)。从事的汽车活动类型(p = 0.483)、频繁弯曲(p = 0.217)、举起重达5 kg (p = 0.071)或25 kg (p = 0.719)的物体以及持续坐着(p = 0.349)或站立(p = 0.996)与腰痛患病率无显著相关性。在双变量分析中，年龄(χ2 = 3.298, P = 0.192)、婚姻状况(χ2 = 0.098, P = 0.754)、从事汽车维修类型(χ2 = 0.493, P = 0.483)、搬运重物达5 kg (χ2 = 3.269, P = 0.071)、搬运重物达25 kg (χ2 = 0.130, P = 0.719)、持续坐着(χ2 = 0.840, P = 0.349)、持续站立(χ2 = 0.002, P = 0.996)与腰bp患病率无显著相关。然而，教育程度(χ2 = 6.121, p = 0.047)与腰痛患病率相关，尽管这种关联在logistic回归后并不持续。结论:尼日利亚汽车技术人员腰痛患病率高，导致缺勤、经济负担和就医需求增加。

Background: There is still lack of rigorous evaluation and evidence for Low-Back Pain (LBP) apps. The objectives of this study were to develop and evaluate the feasibility of a mobile phone-based app of Mechanical Diagnosis and Therapy (MDT) extension exercise; and to examine the correlation between app rating parameters and pain characteristics of patients with non-specific LBP. Methods: A LBP Self-care Mobile-phone App (LBP-SMA) of MDT plus back hygiene was developed following standard iteration and prototyping process. Feasibility of the LBP-SMA was tested in terms of usability, satisfaction and user’s experience using the system usability scale and mobile application rating scale. Quadruple visual analogue scale was used to assess pain intensity of the participants. Data was analyzed using descriptive and inferential statistics at alpha level set at 0.05. Results: Participants’ mean age and pain intensity was 33.8 ± 8.72 years and 45.3 ± 7.23. On a unified scale of 20, functionality (18.5 ± 1.704) and engagement (17.1 ± 2.963) had highest and least objective quality rating on the LBPSMA. Total objective and subjective quality rating of the app was 17.9 ± 1.471 and 18.4 ± 1.173 respectively. LBP-SMA total impact and usability score was 27.2 ± 1.911 indicating high impact and 29.6 ± 1.95 indicating moderate usability. Participants reported that LBP-SMA mostly affects happiness/wellbeing (37.1%), leads to increased behavioural change (48.6%) and targets physical health (100%). There was no significant correlation between participants’ pain characteristics and app rating parameters (p > 0.05). Conclusion: The LBP-SMA has moderate to high usability, functionality, aesthetics and quality rating, and may serve as an effective mobile-app for self-management of longterm LBP.

Background: Leg length discrepancy (LLD) and pelvic obliquity have often been associated with scoliosis in the literature, and neuromuscular contributions have been mentioned as being possibly involved. It is herein hypothesized that a craniocervical junction (CCJ) misalignment (CCJM) may induce a neuromuscular imbalance leading to functional leg length discrepancy, and that re-establishing a proper alignment can result in some LLD disappearance. Methods: A total of n = 40 consecutive scoliotic children aged 7-16 years, 15-50 Cobb angle, were followed for a mean period of 16 months. Children presenting signs and symptoms of CCJM were evaluated with specific radiographs. Patients for whom the misalignment was confirmed received a CCJ adjustment for their re-alignment. Results: All patients presented at first LLD and CCJM. From a mean LLD of 11.0 mm at first presentation (Pre), there was a mean 90% reduction of LLD at the first follow-up visit (1.1 mm) after the re-alignment (mean 15 days Post), and the mean LLD during the complete follow-up period (2.0 mm) was 82% less than that of the mean Pre-LLD, with a mean yearly 1.2 CCJM recurrences and treatments per patient. Conclusion: The results suggest an association between LLD and CCJM among scoliotic children, and LLD may be reversed by means of a CCJ re-alignment which can be sustained. Occasional CCJM recurrences were typically due to falls or hits. The LLD were measured in a horizontal position. It is likely that in a vertical gravitational position, forcing the feet even on the ground, these neuromuscular imbalance forces responsible for this LLD would not disappear but translate into other pelvic and spinal compensatory deviations that may possibly contribute to the development of scoliosis.

Methods: A total of n = 40 consecutive scoliotic children aged 7-16 years, 15-50 Cobb angle, were followed for a mean period of 16 months. Children presenting signs and symptoms of CCJM were evaluated with specific radiographs. Patients for whom the misalignment was confirmed received a CCJ adjustment for their re-alignment. Results: All patients presented at first LLD and CCJM. From a mean LLD of 11.0 mm at first presentation (Pre), there was a mean 90% reduction of LLD at the first follow-up visit (1.1 mm) after the re-alignment (mean 15 days Post), and the mean LLD during the complete follow-up period (2.0 mm) was 82% less than that of the mean Pre-LLD, with a mean yearly 1.2 CCJM recurrences and treatments per patient. Conclusion: The results suggest an association between LLD and CCJM among scoliotic children, and LLD may be reversed by means of a CCJ re-alignment which can be sustained. Occasional CCJM recurrences were typically due to falls or hits. The LLD were measured in a horizontal position. It is likely that in a vertical gravitational position, forcing the feet even on the ground, these neuromuscular imbalance forces responsible for this LLD would not disappear but translate into other pelvic and spinal compensatory deviations that may possibly contribute to the development of scoliosis.","PeriodicalId":16374,"journal":{"name":"Journal of musculoskeletal disorders and treatment","volume":"349 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84867075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background: The Oxford Shoulder Instability Score, abbre-viated OSIS, is a brief, outcome measure self-reported by the patient suffering shoulder instability. Objectives: Our objective was to translate OSIS into Arabic and validate its psychometric properties via test of the reliability, internal consistency, floor and ceiling effects, and validity. Material & Methods: Fifty-five patients were involved in this survey at the baseline and follow-up (14 days after the baseline). We performed the internal consistency test using Cronbach’s α. We calculated Standard Response Mean (SRM) and Pearson’s Correlation to estimate the construct validity and responsiveness of the Arabic OSIS in comparison to Disability of the Arm and Shoulder and Hand (DASH) Score. Results: The Arabic OSIS had a baseline Cronbach’s α of 0.815 and a follow-up value of 0.860. In addition, Intra-class correlation (ICC) of 0.897; (0.813-0.942) indicated high reliability. Arabic versions of OSIS had a strong correlation with DASH score (r = 0.77, p = 0.003) which suggested a good construct validity. Also, moderately correlated changes of baseline to follow-up in OSIS indicated moderate responsiveness. We did not observe any relevant floor and ceiling effect among the responses. Conclusion: Overall, the Arabic version of OSIS proved to be a good and reliable diagnostic tool for patients with shoulder instability.
背景:牛津肩关节不稳定评分，简称OSIS，是一种由肩关节不稳定患者自我报告的简短结果测量方法。目的:我们的目标是将OSIS翻译成阿拉伯语，并通过信度、内部一致性、地板和天花板效应和效度的测试来验证其心理测量特性。材料与方法:55例患者在基线和随访(基线后14天)时参与了本次调查。采用Cronbach’s α进行内部一致性检验。我们计算标准反应均值(SRM)和Pearson’s Correlation来估计阿拉伯语OSIS与手臂、肩膀和手的残疾(DASH)评分相比的结构效度和反应性。结果:阿拉伯OSIS患者的基线Cronbach’s α为0.815，随访值为0.860。此外，类内相关系数(ICC)为0.897;(0.813-0.942)为高信度。阿拉伯文版OSIS与DASH评分有较强的相关性(r = 0.77, p = 0.003)，具有较好的结构效度。此外，在OSIS中，基线到随访的中度相关变化表明中度反应性。我们没有观察到任何相关的下限和上限效应。结论:总的来说，阿拉伯版本的sis被证明是肩关节不稳定患者良好可靠的诊断工具。

Objective: To consider evidence that indicates disc desiccation occurs with regularity in young individuals, despite reports to the contrary. Clinical Features: The clinical histories of 168 chiropractic patients under the age of 50 were reviewed in such a manner that individual patients cannot be identified. Outcome: 20 individuals under the age of 50 were found to exhibit disc desiccation, an occurrence of approximately 12%. It was also indicated that disc desiccation appears to occur with slightly greater frequency in women. Conclusion: Disc desiccation is more prevalent in young trauma victims than was previously believed. Concern regarding sample size was discussed, as were suggestions for further research, such as larger sample size, consideration of the direction of impact, the effects of health or obesity upon the occurrence and/or degree of injury.

Background: Impairment in patients with Duchenne muscular dystrophy (DMD) has been evaluated primarily by muscle fiber microscopy examination. Pathologic examination is limited by the choice of muscle and the invasiveness of muscle biopsy. Magnetic resonance imaging (MRI) of the muscle is a noninvasive method of evaluating muscle preservation. Objective: To compare muscle MRI and clinical function in patients at different stages (from early to terminal stage) of DMD, and to evaluate the correlation between fatty infiltration grade on MRI and clinical functional scale. Materials and methods: Thirty-one boys with DMD, of mean age 7.76 ± 4.99 years, underwent evaluation of clinical functional score grades (scores 1-4) while undergoing muscle MRI of the lower leg, thigh and pelvis. Fatty infiltration grade of 31 muscles was assessed by T1WI MRI using the Mercuri scale (from 0 to 4). Spearman correlation analysis was performed to assess the correlation between T1WI fatty infiltration grade and clinical functional grade. Results: Seventeen muscles showed positive correlations between fatty infiltration grade on T1WI MRI and clinical function. The gluteus maximus, adductor magnus, and gastrocnemius muscles were the most representative, because they were involved during early stages of DMD and their shapes were easier to distinguish on MRI. The obturator internus, gracilis and sartorius muscles were rarely involved until the terminal stage of disease. Damage to these three muscles could be used to predict terminal stage. Fatty infiltration grade on muscle MRI corresponded to microscopic parameters, including a reduced number of muscle cells, arrangement disorder, and fatty and connective tissue infiltration. Conclusion: The results of muscle MRI showed good correlation with clinical function in patients with DMD. Because muscle MRI is a reliable and non-invasive method of assessing muscle damage, MRI is useful in the diagnosis and follow-up of patients with DMD. The Mercuri scale, which measures fatty infiltration on T1WI MRI, is a convenient method of evaluating disease severity and progression.
