Abstract
BACKGROUND No study to date has concurrently evaluated the impact of radiological factors, psychosocial factors, and central sensitization (CS) related symptoms in a single lumbar spinal canal stenosis (LSS) patient cohort. OBJECTIVE To investigate the associations between these factors and clinical symptoms in LSS patients. METHODS We recruited 154 patients with LSS scheduled for surgery. Patient-reported outcome measures and imaging evaluation including clinical symptoms, psychosocial factors, CS-related symptoms, and radiological classifications. Spearman's rank correlation coefficient and multiple regression analyses were employed. RESULTS Spearman's correlation revealed CS-related symptoms positively correlated with low back pain (r= 0.25, p< 0.01), leg pain (r= 0.26, p< 0.01), and disability (r= 0.32, p< 0.01). Pain catastrophizing positively correlated with leg pain (r= 0.23, p< 0.01) and disability (r= 0.36, p< 0.01). Regression analysis showed that pain catastrophizing was associated with disability (β= 0.24, 95%CI = 0.03-0.18), and CS-related symptoms with low back pain (β= 0.28, 95%CI = 0.01-0.09). Radiological classifications were not associated with clinical symptoms. CONCLUSION Our findings suggest that psychosocial factors and CS-related symptoms, rather than radiological factors, seem to contribute to clinical symptoms in patients with LSS.

Abstract
INTRODUCTION Shoulder pain is a substantial medical and socioeconomic problem in most societies, affecting the ability to work or carry out leisure time activities as well as subsequently influencing physical and psychological well-being. According to a nationwide survey in Finland, 27% of the population reported shoulder pain within the last 30 days. In clinical practice, imaging findings of structural abnormalities are typically thought to explain symptoms, even though such findings are also prevalent in asymptomatic individuals, particularly with increasing age. Overall, there is a paucity of high-quality evidence on the prevalence, clinical relevance and prognosis of 'abnormal' imaging findings of the shoulder.The aim of the Finnish Imaging of Shoulder (FIMAGE) study is fourfold: to assess (1) the prevalence of shoulder symptoms and the most common anatomical variants and imaging abnormalities of the shoulder; (2) the concordance between shoulder symptoms, function and imaging abnormalities; (3) the most important determinants of symptoms, function and imaging abnormalities; and (4) the course of shoulder complaints over 5 years. METHODS The FIMAGE target population of 600 participants, aged 40-75 years, will be randomly selected from a nationally representative general population sample of 9922 individuals originally recruited for the Finnish Health 2000 Survey. On giving informed consent, the participants will be invited to a clinical visit that includes assessment of general health, shoulder symptoms, bilateral shoulder examination and imaging of both shoulders with plain radiography and MRI. ETHICS AND DISSEMINATION The study has been approved by the Institutional Review Board of the Helsinki and Uusimaa Hospital District. The findings will be published according to the Strengthening the Reporting of Observational Studies in Epidemiology criteria. TRIAL REGISTRATION NUMBER NCT05641415.

Abstract
INTRODUCTION Low back pain (LBP) is considered a civilization disease that affects people in an increasing number. Discopathy (degeneration of intervertebral discs) is recognised as one of LBP causes. Still, the relationship between the number of discopathy levels and LBP remains unclear. The aim of this study was to evaluate the correlation between the number of discopathy levels with intensity of LBP, functional level and the degree of disability. MATERIALS AND METHODS The prospective, cohort study involved 200 patients aged 27 to 55 years (44.9 ± 9.2 years) with single- or multilevel lumbar discopathy confirmed by imaging examinations. Functional examination included NRSscale, goniometric measurements, Modified Laitinen Pain Questionnaire, Oswestry Disability Index and Back Pain Function Scale. RESULTS There were statistically significant positive correlations between the number of discopathy levels and the age of the subjects (r = 0.266; p = 0.000), BMI (r = 0.158; p = 0.029) and ODI (r = 0.157; p = 0.026). Positive correlation (r = 0.142; p = 0.044) was also observed between the results of Fingertip-to-floortest and the number of levels of discopathy. CONCLUSIONS The number of levels of discopathy was depended on the age and BMI of the patients. It had no effect on pain intensity, range of rotational motion of the lumbar spine and functional status of patients. As the number of levels of discopathy increased, a higher degree of everyday disability was observed.

Abstract
Objective To compare the clinical efficacy and safety of electroacupuncture combined with extracorporeal shock wave therapy (EESWT) and extracorporeal shock wave therapy (ESWT) in the treatment of knee osteoarthritis (KOA). Methods A total of 135 KOA patients who received EESWT treatment were selected as the EESWT group, and 135 KOA patients who received extracorporeal shock wave therapy (ESWT) were selected as the ESWT group. The clinical efficacy, inflammatory factors in joint synovial fluid and adverse events during treatment were compared before and after treatment. Results The clinical effective rate of patients in the EESWT group (89.63 %) after treatment was significantly higher than that of the ESWT group (74.81 %) (p < 0.01). The lysholm kness (LKSS) score and range of motion (ROM) of the patients in the EESWT group after treatment were higher than those of the ESWT group, while Lequesne index score, visual analogue scale (VAS) score and Western Ontario and McMaster Universities Arthritis Index (WOMAC) were lower than those of the ESWT group (p < 0.01). Compared with ESWT group, the changes in the expression levels of nitric oxide (NO), superoxide dismutase (SOD), interleukin 1β (IL-1β), tumor necrosis factor-α (TNF-α), matrix metalloproteinase-3 (MMP-3), and transforming growth factor β1 (TGF-β1) in the synovial fluid of the EESWT group after treatment were significantly greater than those of the ESWT group (p < 0.01). No significant difference in the incidence of adverse events between the EESWT group and the ESWT group (p > 0.05). Conclusion EESWT significantly improves pain symptoms and inflammatory factor levels in KOA patients and is an optional KOA treatment option worthy of clinical attention.

FRONTIERS IN PAIN RESEARCH 2023; 4:1197810. [PMID: 37720912 PMCID: PMC10502338 DOI: 10.3389/fpain.2023.1197810] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Accepted: 08/07/2023] [Indexed: 09/19/2023] Open
Abstract
Background Throughout the literature, pain burden has been assessed by asking different questions, often cross-sectionally, different populations of interest. We know little about pain re-occurrence and how to translate knowledge between pain questions within the population of interest. We aimed to estimate the burden of musculoskeletal pain by estimating prevalence, incidence rates, and re-occurrence risk of back, hand, hip, knee, and foot pain using different questions from UK population-based samples and predict the number of affected individuals in the UK in 2030. Methods We used two UK population-representative studies, with two eight-year-apart follow-ups and two pain questions assessing recent pain episodes and often troubled pain when walking. We estimated prevalence, 8-year incidence rates, and 8-year pain re-occurrence risk for women and men aged 50 years and older and the relation between the two pain questions. Results Among UK individuals older than 50 years, the prevalence of musculoskeletal pain episode was 20%-50%, and the incidence was 20-40/1,000 person-years, while the prevalence of pain when walking was 10%-25%, and the incidence was 6-12/1,000 person-years. The most prevalent musculoskeletal pain types were back and knee pain; of five women experiencing back or knee pain episodes, three are expected to be often troubled by pain. Hip and foot pain had similar estimates in both questions. Hand pain peaked in women aged 50-65 years. Women had higher prevalence and incidence rates, but men had higher 8-year re-occurrence risk of all types of musculoskeletal pain. Reporting a pain episode was associated with two times higher risk, but often troubled by pain when walking was associated with four to seven times times higher risk of the same pain in 8 years. Women and men with a body mass index (BMI) of ≥27 kg/m2 were twice as likely to experience musculoskeletal pain than those with BMI<27 kg/m2. In 2030, we expect 2-7 million people older than 50 years in the United Kingdom to seek site-specific musculoskeletal pain-focused healthcare. Conclusions In individuals older than 50 years, the experience of musculoskeletal pain at least doubles the chance of experiencing it again. Women report musculoskeletal pain more often, but men report more persistent pain. Musculoskeletal pain presents a significant burden to public health.

Insights Imaging 2023; 14:116. [PMID: 37395948 DOI: 10.1186/s13244-023-01463-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Accepted: 06/10/2023] [Indexed: 07/04/2023] Open
Abstract
OBJECTIVES Low back pain is a prevalent public health issue caused by superior cluneal nerve (SCN) entrapment. This study aimed to explore the course of SCN branches, cross-sectional area (CSA) of the nerves, and effects of ultrasound-guided SCN hydrodissection. METHODS SCN distance relative to the posterior superior iliac spines was measured and compared with ultrasound findings in asymptomatic volunteers. The CSA of the SCN, pressure-pain threshold, and pain measurements were obtained from asymptomatic controls and patients with SCN entrapment at various time points after hydrodissection (with 1 mL of 50% dextrose, 4 mL of 1% lidocaine, and 5 mL of 1% normal saline) in the short-axis view. RESULTS Twenty sides of 10 formalin-fixed cadavers were dissected. The SCN locations on the iliac crest did not differ from the ultrasound findings in 30 asymptomatic volunteers. The average CSA of the SCN across different branches and sites ranged between 4.69-5.67 mm2 and did not vary across different segments/branches or pain statuses. Initial treatment success was observed in 77.7% (n = 28) of 36 patients receiving hydrodissection due to SCN entrapment. A group with initial treatment success experienced symptom recurrence in 25% (n = 7) of cases, and those with recurrent pain had a higher prevalence of scoliosis than those without symptom recurrence. CONCLUSIONS Ultrasonography effectively localizes SCN branches on the iliac crest, whereby increased nerve CSA is not useful for diagnosis. Most patients benefit from ultrasound-guided dextrose hydrodissection; however, those with scoliosis may experience symptom recurrence and whether structured rehabilitation can reduce recurrence post-injection should be considered as one perspective in future research. Trial registration ClinicalTrials.gov (NCT04478344). Registered on 20 July 2020, https://clinicaltrials.gov/ct2/show/NCT04478344?cond=Superior+Cluneal+Nerve&cntry=TW&draw=2&rank=1 . Critical relevance statement Ultrasound imaging accurately locates SCN branches on the iliac crest, while enlargement of the CSA is not useful in diagnosing SCN entrapment; however, approximately 80% of SCN entrapment cases respond positively to ultrasound-guided dextrose hydrodissection.

Abstract
Objective We have previously reported that 55% of head and neck cancer survivors have neck disability. However, it is unclear what factors contribute to their neck disability. Our study aim is to determine if survivors with neck disability have evidence of cervical spine degenerative disease assessed by computed tomography (CT). Materials/Methods Cross-sectional analysis of patient-reported neck disability, prospectively collected on survivors of squamous cell carcinomas without recurrence or metastasis over one-year post-treatment. Neck disability and its impact on daily life was measured using the Neck Disability Index (NDI) and compared with cervical CT scans within 6 months. Scans were evaluated for degeneration of the disc and facet of the cervical vertebrae rated on a 5-point scale where 5 indicates more severe disease. Multivariable linear regression was used to analyze the association between NDI and radiographic findings. Results 116 survivors of oropharyngeal carcinomas were identified, predominantly male (81.9%) with an average age of 62.8 ± 8.2 (range 43.8–81.4). Most survivors had advanced stage III-IVa cancer (94.0%) with treatment modalities including surgery (n=26, 52.0%), chemotherapy (n = 45, 90.0%), and radiation therapy (n = 49, 98.0%). Absence of neck disability was observed in 44.0% of survivors, 39.7% had mild disability, and 16.4% moderate disability. The time from treatment to clinic visit was an average of 3.1 ± 2.7 years (range 1.1–13.4). Multivariable analysis of NDI controlling for age, time since treatment, and treatment modality identified an inverse association between NDI and spinal degenerative disease examining cervical discs (−1.46 95% confidence interval (CI) [−2.86, −0.06], p = 0.041) and age (−0.24 95% CI[−0.40, −0.08], p = 0.004). Conclusions Our study shows that neck impairment and pain in head and neck cancer survivors is not sufficiently explained by cervical degeneration related to age or trauma, supporting the theory that post-treatment neck disability occurs as a side effect of treatment. These results support the further assessment of structure and function of cervical musculature and degeneration following HNC treatment.

Effects of body weight and fat mass on back pain - direct mechanical or indirect through inflammatory and metabolic parameters? Semin Arthritis Rheum 2021; 52:151935. [PMID: 35027244 DOI: 10.1016/j.semarthrit.2021.11.007] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2021] [Revised: 11/05/2021] [Accepted: 11/17/2021] [Indexed: 12/29/2022]
Abstract
BACKGROUND While reports indicate the association between obesity and back pain, its mechanism is still unclear. Thus, we aimed to investigate the effects of weight and its components on back pain in middle-aged women while considering direct mechanical and indirect effects via inflammatory and metabolic parameters. METHODS We used data from the Chingford 1000 Women Study, two follow-ups seven years apart. We assessed effects of weight, body mass index (BMI), total fat mass (TFM), total lean mass (TLM) and total bone mineral density (TBMD), measured by dual-energy X-ray absorptiometry, on back pain episode. We used inflammatory (C-reactive protein, interleukin-6, and tumour necrosis factor-alpha) and metabolic parameters (systolic and diastolic blood pressure, triglyceride, high-density lipoprotein cholesterol, and fasting blood glucose) as mediators of indirect effects. We investigated associations of interest cross-sectionally and longitudinally using binary logistic regression and parallel mediation model. RESULTS We included 826 Chingford middle-aged women (mean age=60.7, SD=5.9) from the first used follow-up in cross-sectional and mediation analyses and 645 women that attended the follow-up seven years later, in longitudinal analyses. We found that increased weight was directly associated with increased odds of having back pain episode (OR=1.02; 95% CI 1.01-1.03), similarly as BMI (OR=1.05; 95% CI 1.02-1.08) and TFM (OR=1.03; 95% CI 1.01-1.04) consistently across the cross-sectional and longitudinal models, but not TLM or TBMD. However, we did not find consistent indirect effects of weight or its components through measured inflammatory or metabolic parameters on back pain. CONCLUSIONS Our results show that in middle-aged women, weight, BMI and TFM are directly related to back pain, indicating prominence of mechanical loading effect.

Abstract
OBJECTIVE We aimed to study 19-year body mass index (BMI) patterns and their (1) bidirectional relationship with musculoskeletal pain and (2) mortality risk. STUDY DESIGN AND SETTING We used data from the Chingford study and group-based trajectory modelling to define 19-year BMI patterns. We investigated whether baseline back, hand, hip, and knee pain (as single- and multi-site) predicted 19-year BMI trajectory, and whether 19-year BMI patterns predicted pain in year 20. We explored BMI trajectories and mortality risk over 25 years (life expectancy). RESULTS We included 938 women (mean age: year-1=54, year-20=72) and found seven distinct 19-year BMI trajectories: two normal-weighted (reference), slightly overweight, lower and upper overweight-to-obese, lower and upper obese. BMI patterns capturing the increase overweight-to-obese (BMI 27-34 overtime) were bidirectionally related to knee and multi-site pain. The lower obese pattern (BMI 33-38) was unidirectionally associated with lower limb pain. Women with BMI above 40 had an increased all-cause and cardiovascular mortality risk. CONCLUSION For most postmenopausal women, the overweight WHO category was a transition. Two patterns capturing increase overweight-to-obese were mutually related to musculoskeletal pain, i.e., knee and multi-site pain contributed to becoming obese, and trajectories of becoming obese increased the odds of experiencing pain later.

Abstract
This study [1] characterizes the longitudinal and cross-sectional associations between lumbar radiographic findings and back pain-related disability (BPRD) in the Chingford 1000 Women Study, a population-based longitudinal cohort. One rheumatologist classified the degree of disc space narrowing (DSN), endplate sclerosis or deformity, and osteophytes by combining the number of vertebral bodies involved and type of osteoarthritic changes using the Kellgren-Lawrence grading (KLG) system and a previously described semiquantitative method. The researchers generated separate composite scores for KLG, DSN, and osteophyte grade. The data were derived from different study stages including year 6 physical activity score; year 9 imaging, other covariates, and cross-sectional outcomes; and year 15 longitudinal outcomes. The primary outcome was self-reported back pain of at least one day in the last 12 months from the St. Thomas disability questionnaire. Covariates included age, body mass index, smoking, back pain, bisphosphonate usage, and self-reported physical activity. A total of 650 women and 443 women met inclusion criteria for the cross-sectional and longitudinal analyses, respectively. Median BPRD was zero; approximately two thirds of participants reported no BPRD. No lumbar spine radiographic findings were found in 154/650 women. Of the women with one or more KLG composite changes, osteophyte composite changes, or DSN composite changes, no association was found with BPRD in either analysis. In summary, in this cohort, no association was found between the number of segments with radiographic changes (KLG composite, osteophyte composite, DSN composite) and more severe BPRD.
