Comparing assessment methods of low back pain related disability in student circus artists: A cross-sectional study

BACKGROUND: Student circus artists put constant stress on their back. However, the presence of low back pain (LBP) and related disability in this population remains unclear. OBJECTIVES: To 1) examine LBP history in circus artists and compare related disability scores using the Oswestry Disability Index (ODI) and the Athlete Disability Index (ADI), and 2) examine the correlation between LBP-related disability scores, pain intensity and pain catastrophizing. METHODS: Thirty-three circus students completed an online survey on demographics, training history, and LBP. Participants reporting LBP filled the ODI, ADI, numerical pain rating scale (NPRS), and Pain Catastrophizing Scale (PCS). Descriptive statistics and Pearson’s correlation coefficients were used to assess the correlations between the ODI, ADI, NPRS, and PCS. RESULTS: There was a significant positive correlation between the ODI and ADI (r= 0.77, p< 0.001) and between the NPRS and ADI (r= 0.52, p= 0.03), but no correlation between NPRS and ODI. While the PCS scores were significantly correlated with the NPRS ((r= 0.71; p< 0.001) and the ADI (r= 0.51; p= 0.032), no correlation was observed between the PCS and ODI scores (p= 0.088). Based on the ODI scores, 94.44% of the artists reporting LBP were classified with mild disability, 5.56% moderate, and 0% severe disability as compared to 66.67%, 27.78% and 5.55% with the ADI, respectively. CONCLUSION: Our study highlights the potential of the ADI as an effective tool for assessing LBP-related disability in circus artists, supported by a strong correlation with the NPRS.

Reward system neurodynamics during menstrual pain modulated by COMT Val158Met polymorphisms.

Primary dysmenorrhea (PDM), characterized by cyclic pain, may involve pain modulation within the reward system (RS). The Catechol-O-methyltransferase (COMT) Val158Met polymorphism, which significantly influences dopamine activity, is linked to the regulation of both acute and chronic pain. This study examines the differential neurodynamic modulation in the RS associated with COMT Val158Met polymorphisms during menstrual pain among PDM subjects. Ninety-one PDM subjects underwent resting-state fMRI during menstruation and were genotyped for COMT Val158Met polymorphisms. The amplitude of low-frequency fluctuation (ALFF) and functional connectivity (FC) analyses were used to assess the RS response. Psychological evaluations included the McGill Pain Questionnaire, Pain Catastrophizing Scale, Beck Anxiety Inventory, and Beck Depression Inventory. Val/Val homozygotes (n = 50) and Met carriers (n = 41) showed no significant differences in McGill Pain Questionnaire, Beck Anxiety Inventory, and Beck Depression Inventory. However, Met carriers exhibited lower scores on the Pain Catastrophizing Scale. Distinct FC patterns was observed between Val/Val homozygotes and Met carriers, specifically between the nucleus accumbens (NAc) and prefrontal cortex, NAc and inferior parietal lobe, ventral tegmental area (VTA) and prefrontal cortex, VTA and precentral gyrus, and VTA and superior parietal lobe. Only Met carriers showed significant correlations between ALFF and FC values of the NAc and VTA with pain-related metrics (McGill Pain Questionnaire and Pain Catastrophizing Scale scores). NAc ALFF and NAc-prefrontal cortex FC values positively correlated with pain-related metrics, while VTA ALFF and VTA-prefrontal cortex and VTA-superior parietal lobe FC values negatively correlated with pain-related metrics. This study reveals that the COMT Val158Met polymorphism results in genotype-specific functional changes in the brain's RS during menstrual pain. In Met carriers, engagement of these regions is potentially linked to motivational reward-seeking and top-down modulation. This polymorphism likely influences the RS's responses, significantly contributing to individual differences in pain regulation.

Pillar pain incidence, duration, and psychological correlations in WALANT. A prospective study of 170 patients

PurposeTo prospectively address our patients seeking carpal tunnel release (CTR) to evaluate the incidence, intensity, and duration of pillar pain (PP) and its correlation with catastrophic thinking, depression, and health anxiety.Methods: this is a prospective cohort study consisting of patients who underwent mini-open CTR under WALANT. Pillar pain was evaluated using the table test and was recorded as dichotomous variable and rated with a visual analogue scale (VAS). Patients with a positive result were evaluated on a monthly basis until the test yielded a negative result.To assess catastrophic thinking, health anxiety and depression levels, we employed the Pain Catastrophizing Scale (PCS) the Short Health Anxiety Inventory (SHAI), and the Beck scale respectively. ResultsThe study enrolled 170 patients who underwent CTR using WALANT technique. Among them, 84 patients (49 %) exhibited a positive table test. With exception of age and diabetes, both groups showed comparable demographic characteristics.The mean pain score for patients with a positive test was 3.5 ± 1.5, and the median duration of it was 3 months (interquartile range [IQR] 2–4). The median PCS score was 8 (IQR 2–14) in patients without PP, compared to 8 (IQR 4–11) in patients with PP. In the logistic regression model, the PCS variable had a crude odds ratio (OR) of 1 (95 % CI: 0.96–1.03) and an adjusted OR of 1 (95 % CI: 0.97–1.04). The SHAI score showed a crude OR of 0.97 (95 % CI: 0.93–1.01) and an adjusted OR of 0.97 (95 % CI: 0.92–1.01). The BECK score had a crude OR of 0.99 (95 % CI: 0.96–1.03) and an adjusted OR of 1.02 (95 % CI: 0.98–1.06). ConclusionPatients undergoing mini-open CTR have a risk of 49 % of experiencing PP, which typically registers a pain intensity of approximately 3 points and will last for a median of 3 months. The likelihood of experience it does not depend on catastrophic thinking, depression, and health anxiety. Type of study/level of evidencePrognostic II.

Translation, cross-cultural adaptation and psychometric properties of the Urdu version of the avoidance endurance behavior questionnaire in patients with chronic musculoskeletal pain.

The Avoidance Endurance Questionnaire (AEQ) successfully measures the fear-avoidance and endurance-related responses to chronic pain. The objective of this study was to translate, cross-culturally adapt AEQ into Urdu and assess the reliability and validity of the Urdu version. For the translation and cross-cultural adaptation process, the Beaton Guidelines were followed. A total of 103 participants responded to the Urdu version of the AEQ SF-12, Pain Catastrophizing Scale (PCS) and Numeric Pain Rating Scale (NPRS) at baseline and after 48 hours. The test-retest reliability was assessed using the intraclass correlation coefficient (ICC). Cronbach's alpha was used to measure internal consistency. To measure validity, Pearson's correlation between the subscales of AEQ-Urdu and other outcome measures (SF-12, PCS and NPRS scores) were used (p< 0.05). The mean age of the total 103 participants was 32.7 ± 10.90 among which 45 (43.6%) were male and 58 (56.3%) were female. The pre-final version of the translated AEQ was tested on 40 Urdu speaking participants and no major changes were made. The Cronbach's alpha for all subscales of the AEQ-Urdu ranged from 0.848-0.990. AEQ-U showed an excellent test-retest reliability with the ICC ranging from 0.775-0.996. The majority of the subscales of AEQ showed significant (p< 0.05) positive correlation with pain scales (PCS and NPRS) and negative correlation with the domains of SF-12. The AEQ-U has reliable and valid construct validity, good internal consistency, and test-retest reliability, indicating that it has adequate psychometric features and can be a useful tool for evaluating pain responses in patients with chronic musculoskeletal pain.

Clinical efficacy of magnetic vibration magnetoelectric therapy in the treatment of chronic prostatitischronic pelvic pain syndrome.

The prominent symptoms of chronic pelvic pain syndrome (CPPS) are urogenital pain, lower urinary tract symptoms, psychological problems, and sexual dysfunction. Traditional pharmacological treatments have poor efficacy and more untoward reaction and complications. Magnetic vibration magnetoelectric therapy is a non-invasive form of physiotherapy. Nevertheless, its effectiveness in improving urinary discomfort and relieving pain in patients requires further exploration. To investigate the clinical efficacy of the magnetic vibration magnetoelectric therapy instrument in the treatment of chronic prostatitis (CP)/ CPPS. Seventy patients with CP/CPPS were collected from the outpatient clinic and ward of the Department of Male Medicine, Jiangsu Province Hospital of Traditional Chinese Medicine, and were treated with magnetic vibration magnetoelectric therapy once a day for a period of 14 d. National Institutes of health-chronic prostatitis symptom index (NIH-CPSI), international index of erectile function 5 (IIEF-5), premature ejaculation diagnostic tool (PEDT), generalized anxiety disorder (GAD), patient health questionnaire, the pain catastrophizing scale (PCS) and traditional Chinese medicine syndrome (TCMS) scores were performed before and after treatment. The total effective rate of treatment was 58.5%, and the total NIH-CPSI score, pain symptoms, voiding symptoms, quality of life, IIEF-5, PEDT, GAD, PCS and TCMS scores all decreased significantly (P < 0.05). Magnetic vibration magnetotherapy is effective in improving urinary discomfort, relieving pain, improving quality of life, improving sexual dysfunction and relieving negative emotions such as anxiety in patients with CP/CPPS.

Brain Network Dynamics in Women With Primary Dysmenorrhea During the Pain-Free Periovulation Phase

The human brain is a dynamic system that shows frequency-specific features. Neuroimaging studies have shown that both healthy individuals and those with chronic pain disorders experience pain influenced by various processes that fluctuate over time. Primary dysmenorrhea (PDM) is a chronic visceral pain that disrupts the coordinated activity of brain’s functional network. However, it remains unclear whether the dynamic interactions across the whole-brain network over time and their associations with neurobehavioral symptoms are dependent on the frequency bands in patients with PDM during the pain-free periovulation phase. In this study, we used an energy landscape analysis to examine the interactions over time across the large-scale network in a sample of 59 patients with PDM and 57 healthy controls (HCs) at different frequency bands. Compared with HCs, patients with PDM exhibit aberrant brain dynamics, with more significant differences in the slow-4 frequency band. Patients with PDM show more indirect neural transition counts due to an unstable intermediate state, whereas neurotypical brain activity frequently transitions between 2 major states. This data-driven approach further revealed that the brains of individuals with PDM have more abnormal brain dynamics than HCs. Our results suggested that unstable brain dynamics were associated with the strength of brain functional segregation and the Pain Catastrophizing Scale score. Our findings provide preliminary evidence that atypical dynamics in the functional network may serve as a potential key feature and biological marker of patients with PDM during the pain-free phase. PerspectiveWe applied energy landscape analysis on brain-imaging data to identify relatively stable and dominant brain activity patterns for patients with PDM. More atypical brain dynamics were found in the slow-4 band and were related to the strength of functional segregation, providing new insights into the dysfunction brain dynamics.

Interhemispheric and Corticothalamic White-Matter Dysfunction Underlies Affective Morbidity and Impaired Pain Modulation in Chronic Pain.

Although patients with chronic pain show behavioral signs of impaired endogenous pain modulation, responsible cerebral networks have yet to be anatomically delineated. We used diffusion tensor imaging (DTI) to examine the white-matter alterations in patients with chronic pain compared with healthy subjects. We further measured thermal pain modulatory responses using the offset analgesia (OA) paradigm. We tested whether the white-matter indices be associated with psychophysical parameters reflecting morbidity and modulatory responses of pain in patients, and whether they could serve as diagnostic biomarkers of chronic pain. Twenty-six patients with chronic pain and 18 age- and gender-matched healthy controls were enrolled. After completing psychophysical questionnaires, they underwent OA measurement and whole-brain DTI in a 3 Tesla magnetic resonance imaging scanner. Fractional anisotropy (FA) and radial diffusivity (RD) of the white-matter were computed and compared between the groups with tract-based spatial statistics using the FMRIB Software Library (FSL) software. Correlations were sought among white-matter indices, thermal pain responses, and psychophysical parameters. The white-matter indices and OA-related parameters were tested whether they distinguish patients from controls by receiver operating characteristic analysis. During OA, patients showed a shorter latency to the maximum (maximum visual analog scale [VAS] latency, 16.0 ± 3.7 vs 18.9 ± 3.1 second [mean ± standard deviation, SD]; P = .032) but a longer latency to the minimum pain (OA latency, 15.6 ± 3.5 vs 11.1 ± 4.2 seconds; P = .004) than controls. They showed a smaller mean FA (0.44 ± 0.12 vs 0.45 ± 0.11; P = .012) and a larger mean RD of the global white-matter (0.00057 ± 0.00002 vs 0.00056 ± 0.00002; P = .038) than controls, at specific areas including the corpus callosum, anterior thalamic radiation, and forceps major. FA of the splenium of the corpus callosum was associated with maximum VAS latency (r = 0.493) and OA latency (r = -0.552). The Pain Catastrophizing Scale scores showed strong negative correlations with FA across those specific areas (r = -0.405). Those latencies during OA and white-matter metrics distinguished patients from controls (P < .05). Patients with chronic pain showed dysfunction of the white matter concerned with interhemispheric communication of sensorimotor information as well as descending corticothalamic modulation of pain in association with affective morbidity and altered temporal dynamics of pain perception. We suggest that an impaired interhemispheric modulation of pain, through the corpus callosum, might be a novel cerebral mechanism in chronification of pain.

Cross-cultural adaption, validity, and reliability of the Japanese version of the Central Aspects of Pain in the Knee (CAP-Knee-J) questionnaire in patients with knee pain: a validation study

BackgroundKnee pain is a prominent concern among older individuals, influenced by the central nervous system. This study aimed to translate the Central Aspects of Pain in the Knee (CAP-Knee) questionnaire into Japanese and investigate its reliability and validity in older Japanese individuals with knee pain.MethodsUsing a forward–backward method, CAP-Knee was translated into Japanese, and data from 110 patients at an orthopedic clinic were analyzed. The Japanese version (CAP-Knee-J) was evaluated regarding pain intensity during walking, central sensitization inventory, and pain catastrophizing scale. Statistical analyses confirmed internal validity and test–retest reliability. Concurrent validity was assessed through a single correlation analysis between CAP-Knee-J and the aforementioned measures. Exploratory factor analysis was employed on each CAP-Knee-J item to examine structural validity.ResultsCAP-Knee-J showed good internal consistency (Cronbach’s α = 0.86) and excellent test–retest reliability (intraclass correlation coefficient = 0.77). It correlated significantly with pain intensity while walking, central sensitization inventory scores, and pain catastrophizing scale scores. Exploratory factor analysis produced a three-factor model.ConclusionsCAP-Knee-J is a reliable and valid questionnaire for assessing central pain mechanisms specific to knee pain in older Japanese individuals, with moderate correlations with the CSI and weak with the PCS, thus indicating construct validity. This study supports the development of effective knee pain treatments and prognosis predictions.

Clinical effects of online cognitive behavioral group therapy for chronic pain patients and developing a therapeutic alliance: A pre-post pilot trial.

Research suggests that various psychosocial factors influence chronic pain, with psychotherapies like cognitive behavioral therapy proving effective. However, the limited availability and accessibility have prolonged suffering among patients with chronic pain. This challenge has led to a growing demand for accessible online interventions. We developed an online cognitive behavioral group therapy (CBGT) program, building upon our existing face-to-face CBGT program. We compared the scores obtained by patients during the treatment-as-usual (TAU)period with those collected at the beginning and at the end of the intervention. Patients with chronic pain (N = 22) agreed to participate in the online CBGT program, which was conducted once a week for 12 sessions. The sample size was decided based on the effect sizes of our past face-to-face CBGT. We assessed pain intensity [Visual Analogue Scale (VAS)], pain catastrophizing [pain catastrophizing scale (PCS)] and psychiatric assessment [Beck Depression Inventory-Second Edition (BDI)-II],State-Trait-Anxiety Inventory (STAI), and Short Form Health Survey(SF-36) at three points: entry, pretreatment, and posttreatment. We also evaluated the participants' therapeutic alliance with the treatment staff [short-form version of the Working Alliance Inventory (WAI-S)]. We utilized analyses of variance, Friedman test, paired t-tests, Wilcoxon signed-rank test, and Pearson correlation analysis for data evaluation. Results indicated a significant posttreatment improvement in VAS, PCS, and BDI-II scores compared to the TAU period. Furthermore, posttreatment WAI-S scores increased significantly compared to pretreatment scores. Also, positive correlations were observed among pre- and posttreatment changes in WAI-S, pain intensity, and pain catastrophizing scores. There is a possibility that a therapeutic alliance can be established, and therapeutic effects achieved through an online CBGT intervention; however, additional research is required to substantiate this potential.We have registered this clinical trial in UMIN-CTR on 04/21/2021 with the number UMIN000043982.

An important contributing factor in dry eye disease: somatization.

Somatization is an important mental process that may causes medically unexplained and treatment-resistant somatic symptoms. The aim of the study is assess the presence of somatization in patients with dry eye disease (DED). Eighty-eight patients with no objective DED finding and ongoing DED treatment were included in this prospective and observational study. Patients with subjective symptoms formed the symptom group and patients without subjective symptoms formed the control group. All patients were scored with the Turkish version of the Ocular Surface Disease Index (OSDI), Hamilton Depression Rating Scale (HAM-D), Hamilton Anxiety Rating Scale (HAM-A), Symptom Checklist-90-R (SCL-90R) somatization subscale, Toronto Alexithymia Scale (TAS), Pain Catastrophizing Scale (PCS), and Symptom Interpretation Questionnaire (SIQ). Mean OSDI score was significantly higher in the symptom group than in the control group. The mean HAM-D and HAM-A outcomes did not differ between the groups. The mean SCL-90R somatization subscale, TAS, and PCS scores were significantly higher in the symptom group than in the control group. In the SIQ, somatic attributional style score was significantly higher in the symptom group than in the control group. The SCL-90R somatization subscale, PCS, and somatic attributional style scores had positive and mild-moderate correlation with OSDI scores in the symptom group. The TAS score had positive and moderate correlation with OSDI scores in all sample analyses. Somatization should be considered in patients with DED with chronic ocular surface symptoms. Presence of subjective symptoms resistant to treatment may be an indicator of somatization.

Impact of Midfoot Charcot Arthropathy (Brodsky Type 1) on Patient Reported Outcome Scores

Introduction/Purpose: Charcot arthropathy is a debilitating and challenging clinical problem for patients and providers. Patient reported outcome measures (PROMs) are an effective tool for gauging a patient’s quality of life and daily functioning, but they have not been reported in the setting of Charcot arthropathy. Our goal is to assess PROMs severity in midfoot Charcot arthropathy (Brodsky Type 1), alongside linked demographics and comorbidities. We will compare these values with PROMs from conditions like ESRD, knee and hip arthritis, highlighting Charcot arthropathy's comparable debilitation. Methods: A retrospective chart review identified 67 patients with Brodsky Type 1 Charcot arthropathy by one of two fellowship- trained foot and ankle surgeons at a single academic medical center between years 2015 and 2023. ICD-10 CM codes E11.610, M14.671, and M14.672 were used to identify diagnosis of Charcot arthropathy and radiological interpretation determined Brodsky type. Data collected from patient charts included demographics, medical history, presence of ulcers, and preoperative Visual Analog Scale (VAS), 12-Item Short Form Health Survey (SF-12), Pain Catastrophizing Scale (PCS), Pain Disability Index (PDI), SSS- 8, Foot and Ankle Outcome Score (FAOS), and Foot and Ankle Ability Measure (FAAM) scores and postoperative FAOS and FAAM scores. A One-Way ANOVA was performed to evaluate statistical significance. Averages of preoperative PROM scores were compared to literature values for other diseases. Results: Our cohort was mostly male (58.2%), with mean age 61.73 years, BMI 32.9, and A1C 6.9. Initial presentation revealed 50.7% had ulcers. Brodsky type 1 (midfoot) had notably the lowest pre-op PROM scores when compared to other Brodsky types: PDI Recreation (p=.033), FAOS Symptoms and Stiffness (p=.044), and FAOS Recreation (p=.027). Ulcer presence yielded significantly lower FAAM-ADL scores (p=.038), while other PROMs showed no statistical difference. Our mean VAS score was 53.34 which was higher than hip arthritis VAS (43.0) but lower than ESRD VAS (60.0) and knee arthritis VAS (64.2). Our SF-12 PCS scores (29.4) exceeded prior reports (hip 28.5, knee 28.6), while SF-12 MCS scores were higher in earlier studies (hip 49.6, knee 51.5) than our 43.8. Conclusion: Patients with Charcot arthropathy struggle in daily tasks, reflected in lowered FAOS ADL scores. Brodsky type 1 patients also face challenges in higher-level activities, evident in reduced PDI recreation and FAOS recreation scores. Those with ulcers similarly encounter issues in daily tasks, seen in lower FAAM ADL scores. Brodsky type 1 patients also experience debilitating pain as noted by higher VAS scores when compared to known debilitating conditions such as hip and knee arthritis. Comparatively minor differences in knee and hip arthritis SF-12 PCS scores indicate significant physical limitations for these patients.

Effects of Manual Therapy Plus Pain Neuroscience Education with Integrated Motivational Interviewing in Individuals with Chronic Non-Specific Low Back Pain: A Randomized Clinical Trial Study.

Background and Objectives: Chronic non-specific low back pain (CNLBP) persists beyond 12 weeks. Manual therapy recommended for CNLBP demonstrates short-term efficacy. Pain Neuroscience Education (PNE) teaches patients to modify pain perception through explanations, metaphors, and examples, targeting brain re-education. Motivational Interviewing (MI) enhances motivation for behavioral change, steering patients away from ambivalence and uncertainty. These approaches collectively address the multifaceted nature of CNLBP for effective management. The aim of this study was to investigate a manual therapy intervention combined with PNE with MI on pain, pressure pain threshold (PPT), disability, kinesiophobia, catastrophizing, and low back functional ability in individuals experiencing CNLBP. Materials and Methods: Sixty adults with CNLBP were randomly divided into three equal groups (each n = 20). The first group received manual therapy and PNE with integrated MI (combined therapy group), the second group underwent only manual therapy (manual therapy group), and the third group followed a general exercise program at home (control group). Pain in the last 24 h was assessed using the Numeric Pain Rating Scale (NPRS), functional ability with the Roland-Morris Disability Questionnaire (RMDQ), PPT in the lumbar region through pressure algometry, kinesiophobia with the Tampa Scale for Kinesiophobia (TSK), catastrophizing with the Pain Catastrophizing Scale (PCS), and performance using the Back Performance Scale (BPS) at baseline, in the fourth week, and six months post-intervention. Results: Statistically significant differences between the intervention groups and the control group were found in both the fourth-week measurement and the six-month follow-up, as evident in the NPRS and RMDQ scores, as well as in the total values of tested PPTs (p < 0.05). Differences were also observed between the two intervention groups, with a statistically greater improvement in the combined therapy group at both time points (fourth week and six-month follow-up) (p < 0.05). Regarding the TSK and PCS scores in the fourth week, statistically significant differences were observed between the two intervention groups compared to the control group, as well as between the two intervention groups (p < 0.05). However, in the six-month follow-up, statistically significant differences were found only between the combined therapy group and the other two groups, with the combined therapy group showing significant improvements (p < 0.05). In relation to BPS, both intervention groups exhibited statistically significant differences compared to the control group in the fourth week, without any significant differences between the two intervention groups. However, in the six-month follow-up, significant differences were noted between the combined therapy group and the other two groups (p < 0.05), with combined therapy demonstrating greater improvement. Conclusions: The addition of PNE with integrated MI enhanced the positive effects of a manual therapy intervention in all outcome measures. The combination of manual therapy plus PNE with integrated MI appeared to provide greater improvements compared to the isolated application of manual therapy, and these improvements also lasted longer. These short- and long-term positive effects are likely attributed to the combination of PNE with integrated MI, which contributed to increasing the effectiveness of the treatment. Further studies are required to investigate the optimum dosage of manual therapy and PNE with integrated MI in individuals with CNLBP.

Pain Catastrophizing and Impact on Pelvic Floor Surgery Experience

ABSTRACT Duration, intensity, and management of pain and discomfort may all be affected by experience, personality, and medical and psychosocial comorbidities. A negative cognitive-affective response to actual or anticipated pain, which impacts the pain experience, is called pain catastrophizing. The scale utilized for identifying individuals who magnify, feel helpless to manage, anticipate, or ruminate on pain is known as the Pain Catastrophizing Scale (PCS) and is composed of a 13-question validated measure and 3 subscales. The scale's score ranges from 0 to 52, where scores of 30 and greater indicate pain catastrophizing (30 points is the 75th percentile for PCS score distribution in patients with chronic pain). Pain catastrophizing is associated with increased pain severity, pain persistence, and opioid consumption following surgery, as well as poorer response to endometriosis treatments. Approximately 300,000 prolapse surgical procedures are performed in the United States annually, and because little is known about pain catastrophizing on perioperative pain, pelvic floor symptom distress/impact, and voiding trial (VT) performance following urogynecologic surgery, the authors' primary aim was to assess baseline pain catastrophizing on preoperative pelvic floor symptom impact and distress. The secondary aims included assessing the impact of pain catastrophizing on voiding function and postoperative pain following pelvic floor surgery. The patients for this prospective cohort study included self-identifying female patients undergoing surgery for stress urinary incontinence (SUI) and/or pelvic organ prolapse from March 2020 to December 2021. Inclusion came following completion of appropriate surveys and subsequent surgery. Exclusion was merited through surgery for reasons besides SUI or prolapse. At the baseline patient visit, a PCS score of 30 or greater was defined as pain catastrophizing. The initial visit also included recording data such as body mass index, age, benzodiazepine use, chronic opioid use, anxiety and depression diagnoses, postoperative prolapse stage, bothersome urgency urinary incontinence, and preoperative postvoid residual volume. Charts were used for abstracting surgical data, such as operative time, estimated blood loss, type of pelvic reconstructive surgery performed, and midurethral sling placement. Surgeries were all performed by fellowship-trained reconstructive pelvic surgery providers. Postanesthesia care unit (PACU) nurses and clinic staff were masked to preoperative PCS scores obtained in the PACU and postoperative clinic visits. A standardized void trial was performed. Of 320 participants in this cohort, 46 had a pain catastrophizing score of ≥30. Mean age was 60.0 ± 12.8 years. Bivariate analysis indicated that the pain catastrophizing group had higher average body mass index and greater preoperative use of benzodiazepines. Variants such as SUI rates, urgency urinary incontinence, or prolapse stage had no significant differences between groups, yet preoperative pelvic floor symptom distress and impact scores were clinically and statistically significantly higher in the catastrophizing group. Higher PACU pain scores were associated with pain catastrophizing, but not first postoperative VT failure. A significant association between pain catastrophizing and symptom distress remained following multivariable analysis, as well as a relationship between high PCS scores and symptom impact. All quality-of-life subscales maintained the significant associations. This study, although unique in describing pain catastrophizing in this setting, includes various limitations such as its single-institutional nature, which may limit external generalizability. Furthermore, generalizability may also be limited for those electing nonsurgical management, as the study selected for women choosing surgery. Study strengths include its large number of patients cared for by fellowship-trained providers in a similar manner with uniform surgical practice and timing of measures for assessing pelvic pain and pelvic floor symptoms. Also, a relatively standard VT method was utilized. Although further investigation is warranted for describing pain catastrophizing and its role with pelvic floor symptoms and pain postoperatively, the results of this study support other investigative findings, which indicate the importance of understanding pain catastrophizing and its potential effect on patients undergoing pelvic floor surgery. Future studies around this relationship can potentially enable health care providers to tailor perioperative care for individuals with pain catastrophizing.

A potential link between inflammatory profiles, clinical pain, pain catastrophizing and long-term outcomes after total knee arthroplasty surgery.

Chronic postoperative pain after total knee replacement (TKR) is a major clinical problem. It is still unclear if specific inflammatory mediators are associated with long-term postoperative pain complications. The current exploratory study aimed to (1) evaluate a multiplex of inflammatory mediators 5 years after TKR surgery in patients with different degrees of postoperative pain intensities and (2) study any association of the markers with clinical pain intensity, cognitive and functional outcomes. Plasma samples were collected 5 years after TKR surgery from 76 knee patients (43 females; 33 males) and analysed for 44 inflammatory markers. Pain (using visual analogue scale, VAS), the pain catastrophizing scale (PCS) and the Oxford knee score (OKS) were evaluated. Patients were categorized as high or low groups based on VAS, PCS and OKS scores. Associations between inflammatory markers, VAS, PCS and OKS were analysed and the marker expressions were compared between groups. Pearson's correlations found 12 biomarkers associated with VAS (p < 0.05), 4 biomarkers with PCS and 3 biomarkers with OKS (p < 0.05). Four markers were altered in patients suffering from high compared to low chronic postoperative pain, three markers were altered in high compared to low catastrophizers and three markers were altered in patients with poor functional scores (p < 0.05). The present exploratory study suggests that low-grade inflammation might be present in a subset of patients with high pain, high catastrophizing and low function 5 years after TKR. These exploratory results provide insights into some of the long-term postoperative complications after TKR surgery. This exploratory study evaluated a subset of inflammatory markers and the association to clinical pain intensity, knee function and pain catastrophizing in patients 5 years after total knee replacement surgery. Our results provide insights into the understanding of the underlying mechanisms that may drive the long experience of pain after TKR surgery.

Association between smoking and central sensitization pain: a web-based cross-sectional study.

This study aimed to investigate whether smoking is an independent risk factor for central sensitization syndrome (CSS) in individuals with pain as measured by the Central Sensitization Inventory (CSI). In 2020, we conducted an Internet survey targeting 2000 ordinary residents of Japan (aged 20-69years) who had pain symptoms from October to November 2020. A multiple regression analysis was performed on the association between smoking status (nonsmokers and current smokers; Brinkman index) and CSI values. Moreover, compared to nonsmokers, the relative risk (RR) of the CSI cut-off score of 40 points or higher among current smokers was calculated using a modified Poisson regression model. Covariates included age, sex, body mass index, marital status, equivalized income, exercise habits, history of hypertension, history of hyperlipidemia, history of diabetes, pain chronicity, and Pain Catastrophizing Scale score. This study analyzed 1,822 individuals (1,041 men and 781 women). Among those experiencing pain, current smoking was associated with the increase in CSI values (β = 0.07). The Brinkman index was also significantly associated with the increase in CSI values (β = 0.06). Current smoking also increased the risk of being over the CSI cut-off score, with a relative risk (RR) of 1.29 (95% confidence intervals, 1.04-1.60). Younger age, being women, experiencing chronic pain, and higher pain catastrophizing thinking were also significantly associated with increased CSS severity, independent of smoking status. Smoking is an independent risk factor for CSS. This indicates that smoking may be an important factor in the management of central pain disorders.

The effect of visual feedback-based clinical monitoring application in patients with chronic low back pain: a randomized controlled trial

PurposeNo study has addressed the effect of patient-reported outcomes as a visual feedback tool during telerehabilitation. This study aimed to investigate the effect of a visual feedback-based monitoring application PhysioAnalyst on pain, pain catastrophizing, physical functions, quality of life, usability, satisfaction, and exercise adherence in individuals with chronic low back pain (CLBP).MethodsA single-blind, randomized controlled trial was conducted with 44 CLBP patients. Participants were randomized into two groups: the tele-assessment feedback group (TAFG) (n = 22) and the control group (CG) (n = 22). Participants were assessed before the intervention, at the 4th week and after the intervention. Individuals were assessed using the Visual Analog Scale (VAS), Nottingham Health Profile (NHP), Pain Catastrophizing Scale (PCS), Oswestry Disability Index (ODI), Telehealth Usability Questionnaire (TUQ), Telemedicine Satisfaction Questionnaire (TSQ), and Exercise Adaptation Rating Scale (EARS) via PhysioAnalyst. Individuals in the TAFG group received graph-based visual feedback on assessment data in week 4.ResultsThe improvement in VAS, NHP, ODI, TUQ, TSQ, and EARS of individuals in TAFG was statistically significant (p < 0.05). Only ODI and PCS scores in CG showed significant improvement (p < 0.05). After the graphics-based visual feedback presented to the TAFG, the VAS, NHP-Emotional, NHP-Sleep, NHP-Total, PCS, TUQ, TSQ, ODI, and EARS scores gained more than CG (p < 0.05).ConclusionThe results confirmed the additional contribution of telerehabilitation’s graphics-based visual feedback in pain, pain catastrophizing, disability, quality of life, and exercise participation. Since the importance of continuity in long-term rehabilitation in patients with CLBP is comprehended, feedback to increase patient motivation can be added to telerehabilitation applications.

Greater Mental Health Burden is Associated With Poor Postoperative Pain Control and Increased Opioid Utilization Following Total Shoulder Arthroplasty.

Prolonged opioid use is associated with higher complications and worse patient-reported outcomes following total shoulder arthroplasty (TSA). Identified risk factors for prolonged postoperative use are related to several medical comorbidities, gender, diagnoses of anxiety or depressive disorders, and preoperative opioid use. In this study, we hypothesized that patient-reported mental health characteristics can help to identify patients at risk of worse postoperative pain control, worse sleep, and higher opioid utilization following TSA. Ninety-three consecutive patients were asked to fill out 2 mental health questionnaires prior to undergoing TSA. Following surgery, patients filled out a daily pain diary to track their daily pain, pain medication use, and quality and duration of their sleep for 30 days. Preoperative opioid use and postoperative refill were determined by the New York State Prescription Monitoring Program. Mixed-model linear regressions were conducted. Significance was defined as p < 0.05. Postoperative opioid refill was associated with female gender, preoperative opioid therapy, higher inpatient opioid use, worse anxiety, depression, somatization, and pain catastrophizing scores. The number of days using opioids postoperatively was associated with worse pain catastrophizing scale (PCS) and somatization scores (patient health questionnaire-15). Preoperative opioid therapy was associated with worse somatization scores, whereas no opioids used after surgery were associated with better somatization scores. Worse sleep quality and duration were associated with worse PCS scores. A greater mental health burden is associated with worse postoperative pain control and higher opioid utilization during the acute postoperative period. This is especially evident in the pain catastrophizing and somatization domains.

Pain Catastrophizing in Dental Students and its Relation with Dental Anxiety and Pain Intensity

Aim: The aim of this study was to evaluate the pain catastrophizing and dental anxiety among dental students. Additionally, we explore the relation of pain catastrophizing scores with gender, pain intensity and dental treatment experience. Material and Methods: This questionnaire study was conducted among dental students in 2020. The questionnaire, which was prepared via Google forms and students studying in different faculties of dentistry filled out the questionnaire via e-mail. The Visual Analogue Scale (VAS), the Corah's Dental Anxiety Scale (C-DAS), and Pain Catastrophizing Scale (PCS), helped the clinician examine how the participants felt and what they thought regarding pain, were used. Spearman's rho correlation was used to analyze the correlations between the variables. The MANOVA test was used to evaluate whether the main effects of gender, term, and treatment on C-DAS and PCS were significant. Results: Of the total, 22.5% of the students were considered to be catastrophic individuals. According to the regression model, a one-unit increase in VAS value led to an increase of 0.164 in the total PCS score. Similarly, while the increase in the C-DAS score led to an increase of 0.575 in the PCS score, girls' PCS score was higher by 4.091. Conclusion: Our study is the first to report the prevalence of pain catastrophizing among dental students and the effect of gender and PCS-subscales. The increased knowledge level of dental students about pain may effectively reduce the tendency toward pain catastrophizing.
