Objective

The purpose of this study was to examine sagittal spinal movements during walking with frameless and internal frame backpacks.

Methods

Twenty adult students from a chiropractic college walked on a treadmill while wearing inertial measurement units mounted on the head, T1 and T12 vertebrae, and sacrum. They walked without a backpack, with a backpack loaded with 6.8 kg, and after 15 minutes walking with the loaded pack. Day 1, they wore a backpack with no structural support; day 2, they wore an internal frame backpack with a hip belt and chest compression straps. Cyclic sagittal flexion and extension endpoints were identified using an application written in the R language.

Results

Participants walked with the lumbar spine in slight flexion throughout all trials with both packs; flexion significantly increased with load and with time, more so with the frameless pack. The thoracic region showed progressive extension with load and time, significant only for the frameless pack. The cervical region trended toward progressive extension with load and time, with no significant changes for either pack.

Conclusion

In this group of adult students walking on a treadmill, there were trends of increasing lumbar flexion, thoracic extension, and cervical extension, with changes more pronounced with a frameless backpack than one with an internal frame.

目的研究无框架背包和内框架背包行走时矢状位脊柱运动情况。方法20名成年大学生在跑步机上行走，在头部、T1、T12椎体和骶骨上安装惯性测量装置。他们在没有背包的情况下行走，背着6.8公斤的背包行走，并在15分钟后背着背包行走。第一天，他们背着没有结构支撑的背包；第二天，他们穿着一个内置框架的背包，背包上有腰带和胸部压缩带。使用R语言编写的应用程序确定了循环矢状屈曲和伸展端点。结果在所有试验中，受试者在行走时腰椎轻微弯曲；弯曲度随着负载和时间的增加而显著增加，无框包装更是如此。随着负荷和时间的增加，胸部区域呈渐进式延伸，仅在无框背包中有显著性。随着负荷和时间的推移，颈椎区域趋向于渐进式伸展，两组均无明显变化。结论在这组在跑步机上行走的成年学生中，腰屈、胸伸和颈椎伸有增加的趋势，无框架背包的变化比有内框架背包的变化更明显。

Objective

The purpose of this study was to determine the relationship between pain, disability, and lumbar multifidus activity in people with chronic low back pain while standing.

Methods

This cross-sectional study included baseline analysis of a randomized controlled trial of 150 patients with chronic low back pain. Pain intensity during standing, disability, and lumbar multifidus activity was assessed using a visual analog scale, the Oswestry Disability Index questionnaire, and surface electromyography, respectively. Multiple linear regression was used to analyze the association between lumbar multifidus activity, pain during standing, and disability.

Results

Lumbar multifidus (LM) activity on the right side did not significantly correlate with pain intensity during standing, except for the left-side percent maximum voluntary contraction of the LM, which showed a significant positive correlation with pain intensity (r = 0.328, P < .001). There was a positive correlation of functional disability with right-side LM activity (r = 0.180, p < .05) and left-side LM activity (r = 0.351, p < .001).

Conclusion

An increase in lumbar multifidus activity is correlated with increased pain during standing and disability.

Banibrata Das Ph.D

Objectives

The objective of this study was to determine the relationship between low back pain (LBP) and ergonomic and psychosocial risk factors encountered by railway track maintainers in India.

Methods

A cross-sectional survey was conducted in India. Socio-demographics, ergonomics, and psychosocial risk factors were examined among railway track maintainers. A modified Nordic Musculoskeletal Disorder Questionnaire was also administered to participants. The working posture of the participants was assessed using the Ovako Working Posture Analysis System (OWAS). Univariate logistic regressions were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) among participants.

Results

90.3% of railway track maintainers reported low back pain. In the univariate analysis, repetitive work (OR-2.848; 95% CI-1.34-6.051), awkward posture (OR-33.84; 95% CI-12.334-92.896), pulling loads (MMH) (OR- 6.300; 95% CI-2.802 to 14.166), and long working hours (OR- 4.553; 95% CI-1.910 to 10.854) all demonstrated significant relationships with LBP among participants. Psychosocial factors, such as work demand targeting specific productivity (97.3%), monotony of work (91.8%), perceived inadequacy of income (83.3%), and rigidity in work methods (86.4%), have a relationship with LBP. According to the OWAS posture analysis, most of the working postures of railway track maintainers require immediate correction.

Conclusions

The high prevalence of LBP among railway track maintainers and its significant associations with ergonomic and psychosocial risk factors indicate a need to follow suggested preventive measures to avoid LBP.

目的本研究的目的是确定印度铁路轨道维修人员遇到的腰痛（LBP）与人体工程学和社会心理风险因素之间的关系。方法在印度进行横断面调查。对铁路轨道维修人员进行社会人口统计学、人体工程学和社会心理风险因素的研究。还对参与者进行了修改后的北欧肌肉骨骼疾病问卷调查。使用Ovako工作姿势分析系统（OWAS）评估参与者的工作姿势。结果90.3%的铁路轨道维护人员报告腰痛；在单变量分析中，重复性工作（OR-2.848; 95% CI-1.34-6.051）、笨拙姿势（OR-33.84; 95% CI-12.334-92.896）、拉力（MMH）（OR- 6.300; 95% CI-2.802 - 14.166）和长时间工作（OR- 4.553; 95% CI-1.910 - 10.854）均与腰痛有显著关系。社会心理因素，如以特定生产力为目标的工作需求（97.3%）、工作单调（91.8%）、感知到的收入不足（83.3%）和工作方法僵化（86.4%），与LBP有关系。根据OWAS姿势分析，铁路轨道维修人员的大部分工作姿势需要立即纠正。结论铁路维修人员腰痛的高发病率及其与人体工程学和社会心理危险因素的显著相关性表明，需要遵循建议的预防措施来避免腰痛。

Objective

This study aimed to measure whether 3-minute warm/cold-contrast footbaths have psychological and physiological relaxation effects, focusing on the effects of the order of the warm and cold footbaths.

Methods

Thirty healthy young adults (age: 19 ± 2 years; 23 female) participated in the study. Participants performed 2 conditions on separate days: a warm-cold footbath condition (WC condition) starting with a warm footbath (42°C warm water) and ending with a cold footbath (15°C to 20°C) and a cold–warm footbath condition (CW condition) starting with a cold footbath and ending with a warm footbath. The warm footbath was performed for 45 seconds and the cold footbath for 15 seconds per set, for a total of 3 sets of 3 minutes in length. Psychological responses were evaluated before and after the footbath using a questionnaire, and physiological responses were evaluated during the footbath by measuring heart rate, heart rate variability, and pupil diameter.

Results

Psychological relaxation and leg lightness significantly increased after the footbath under both conditions (P = .04, P < .001). Leg warmth increased significantly after the footbath only in the CW condition (P = .001). Heart rate and pupil diameter decreased significantly from the beginning to the end of the footbath under both conditions (P = .001, P < .001); no change in heart rate variability was observed.

Conclusion

Three-minute warm/cold-contrast footbaths had psychological and physiological relaxation effects, regardless of the order of the warm and cold footbaths. The psychological relaxation effect may be greater if the warm footbath is at the end.

目的研究3分钟冷暖对比足浴是否具有心理和生理上的放松作用，重点研究冷暖对比足浴先后顺序的影响。方法30例健康青年（年龄19±2岁，女性23例）参与研究。参与者在不同的日子里进行了两种条件：冷暖足浴条件（WC条件），以温暖的足浴（42°C的温水）开始，以冷的足浴（15°C到20°C）结束；冷暖足浴条件（CW条件），以冷的足浴开始，以温暖的足浴结束。热足浴每组45秒，冷足浴每组15秒，共3组，每组3分钟。通过问卷调查评估足浴前后的心理反应，并通过测量心率、心率变异性和瞳孔直径来评估足浴期间的生理反应。结果两种条件下足浴后心理松弛度和腿部轻盈度均显著增加（P = 0.04, P < 0.001）。只有在CW条件下，足浴后腿部温度才显著增加（P = .001）。两种条件下，足浴开始至结束时，心率和瞳孔直径均显著下降（P = 0.001, P < 0.001）；没有观察到心率变异性的变化。结论3分钟温/冷对比足浴不论先后顺序，均有心理和生理放松作用。如果在结束时进行热足浴，心理放松的效果可能会更大。

Objective

The purpose of this case report is to describe the collaborative management between a primary care physician and a chiropractic resident in a large private-sector integrated healthcare system for the evaluation and treatment of a patient with meralgia paresthetica.

Clinical Features

A 46-year-old male presented to a Family Medicine department within a large integrated healthcare system’s outpatient clinic for an annual physical and evaluation in which he reported the presence of upper left anterior thigh numbness of 2 days duration.

Intervention and Outcome

The primary care physician and chiropractic resident collaborated on differential diagnosis and agreed upon a coordinated plan of care inclusive of a referral for chiropractic management. A case appropriate history and problem focused physical examination was conducted, which revealed clinical findings consistent with meralgia paresthetica. A treatment plan consisting of anti-inflammatory medication, therapeutic exercise, soft tissue mobilization techniques, patient education, and ergonomic instruction was initiated as part of an evidence-informed approach. The patient responded favorably to collaborative care and demonstrated improved patient reported outcomes as assessed with a verbal numerical rating scale.

Conclusion

The combined management demonstrated key themes of effective healthcare collaboration and resulted in the resolution of the patient's condition.

Objective

The purpose of this case report is to describe a multimodal treatment approach for a middle-aged woman with fibromyalgia (FM).

Clinical Features

A 52-year-old woman presented with FM. She did not respond to pharmaceutical interventions. Her condition manifested as focal, bilateral pain in her hands, wrists, lumbar spine, thoracic spine, and cervical spine. She experienced pain 75% to 100% of her day, which was exacerbated by carrying or lifting, changing positions, household chores, lying down, raising her arms above her shoulders, and stress. Due to the severity of her condition, she had poor grip strength and transient tremors in her hands. The pain interfered with her sleep every night.

Intervention and Outcome

The treatment strategy involved a multimodal approach using instrument-assisted spinal manipulation to the lumbar, thoracic, and cervical spine, hands and wrists soft tissue massage, and supplementation with omega-3 fatty acids, N-acetylcysteine, l-theanine, and valerian once per day. After treatment, her pain was manageable. She reported improvements in her range of motion in her hands, wrists, and lumbar, thoracic, and cervical spine, and improvements in her hand tremors, grip strength, and sleep quality.

Conclusion

A female with FM had improvements in her symptoms and quality of life following a multimodal conservative treatment regimen.

目的本病例报告的目的是描述一个多模式治疗方法的中年妇女纤维肌痛（FM）。临床特征：52岁女性，表现为FM。她对药物干预没有反应。她的病情表现为手部、手腕、腰椎、胸椎和颈椎的局灶性双侧疼痛。她一天中有75%到100%的时间都感到疼痛，搬运或举起、改变姿势、做家务、躺下、将手臂举过肩膀和压力会加剧疼痛。由于她的病情严重，她的握力很差，双手会短暂颤抖。疼痛每晚都影响她的睡眠。干预措施和结果：治疗策略包括多模式的方法，使用器械辅助脊柱操作腰椎、胸椎和颈椎，手和手腕软组织按摩，每天补充1次omega-3脂肪酸、n -乙酰半胱氨酸、l-茶氨酸和缬草。经过治疗，她的疼痛是可控的。患者报告其手部、手腕、腰椎、胸椎和颈椎的活动范围有所改善，手部震颤、握力和睡眠质量有所改善。结论1例女性FM患者经多模式保守治疗后，症状和生活质量均有改善。

Radiomorphometric Analysis of Trabecular and Cortical Bone of the Mandible in Patients with Behçet Disease 下颌骨骨小梁和皮质骨的放射形态分析

Journal of chiropractic medicine

Pub Date : 2025-01-01 DOI: 10.1016/j.jcm.2025.08.010

Objective

The aim of this study was to analyze the radiomorphometric parameters of trabecular and cortical bone of the mandible in patients with Behçet disease.

Methods

This study comprised 24 patients diagnosed with Behçet disease, consisting of 16 women and 8 men age and sex matched healthy individuals. The radiomorphometric parameters examined included fractal dimension, mandibular cortical width, and mandibular cortical index.

Results

The mean fractal dimension values of the all regions were higher in the patients of Behçet disease group in the control group. But there were no significant differences in the mean fractal dimensions of selected regions between the 2 groups, except anterior region (P < .05). There were no significant differences in mandibular cortical width between the 2 groups (P > .05). The mean mandibular cortical width was 4.66 mm in the patients with Behçet disease and 5.23 mm in the control group.

Conclusion

Patients with Behçet disease showed reduced mandibular bone quality, possibly due to malabsorption. This condition is associated with increased cortical bone porosity and a thinner cortex.

目的分析behet病患者下颌骨骨小梁和皮质骨的放射形态学参数。方法本研究纳入24例诊断为behaperet病的患者，其中女性16例，男性8例，年龄和性别匹配。检测的放射形态学参数包括分形维数、下颌骨皮质宽度和下颌骨皮质指数。结果behet病组患者各区域分形维数平均值均高于对照组。除前区外，两组间各区域平均分形维数差异无统计学意义（P < 0.05）。两组患者下颌骨皮质宽度差异无统计学意义（P > 0.05）。behet病患者下颌骨皮质平均宽度为4.66 mm，对照组为5.23 mm。结论behaperet病患者下颌骨质量下降，可能是由于吸收不良所致。这种情况与皮质骨孔隙度增加和皮质变薄有关。
