UNASSIGNED: To assess pain outcomes, stress levels and body awareness among patients with chronic pain and explore potential associations between these variables.
UNASSIGNED: An explorative study.
UNASSIGNED: Patients with chronic pain in primary and specialist care were assessed regarding pain intensity using the Numerical Rating Scale (NRS; 0-10 point scale) and stress levels using the Stress and Crisis Inventory (SCI-93; 0-140). To assess body awareness, multidimensional assessment of interoceptive awareness (MAIA; 0-5), a widely used self-report measure of interoceptive bodily awareness was used.
UNASSIGNED: Participants (n = 42) reported an average NRS of 4.4, elevated stress levels and low body awareness. Stress levels were moderately correlated with pain intensity (r = 0.53; p < 0.001; 95% confidence interval [CI] 0.25-0.72) and number of pain sites (r = 0.58; p < 0.001; 95% CI 0.32-0.76). The regression analysis showed that pain outcomes predicted stress level scores and explained almost 50% of variance (R 2 = 0.47, p < 0.001). Moreover, shorter pain duration predicted a higher body awareness (p = 0.04).
UNASSIGNED: In patients with chronic pain, high pain intensity and multiple painful sites seem to be associated with impaired stress regulation. The patients had low body awareness, which was negatively influenced by pain duration.

UNASSIGNED: Moderate-to-severe intensity pain is reported on the first day following lower abdominal surgery. No study has compared transversus abdominis plane (TAP) block with retrolaminar block (RLB) in laparoscopic inguinal hernia surgery for postoperative pain relief.
UNASSIGNED: In this prospective, randomized trial, 42 male patients of American Society of Anesthesiologists (ASA) physical status I and II, aged 18-65 years, and having a BMI <40 kg/m2 received TAP or RLB following laparoscopic inguinal hernia surgery. A standard general anesthetic technique was performed. Patients were randomized into two groups: single-shot TAP block (group I) (n = 21) or the RLB (group II) (n = 21) with bilateral 20 ml of 0.375% ropivacaine. Postoperatively, IV paracetamol 1 g was administered as rescue analgesia. Postoperative cumulative Visual Analogue Scale (VAS) score 24 hours after surgery was considered as the primary outcome.
UNASSIGNED: Postoperative cumulative VAS score at rest at 24 h, represented as mean ± S.D (95% CI), in the TAP block group was 3.54 ± 3.04 (2.16-4.93) and in the RLB group was 6.09 ± 4.83 (3.89-8.29). P value was 0.112 and VAS on movement was 7.95 ± 3.41 (6.39-9.50 [2.5-15.0]) in TAP block group, whereas P value was 0.110 and VAS on movement was 10.83 ± 5.51 (8.32-13.34) in the RLB group.
UNASSIGNED: Similar postoperative cumulative pain score on movement at 24 h was present in patients receiving TAP block or RLB. However, VAS score at rest and on movement was reduced in patients receiving TAP block at 18 and 24 h postoperatively.

OBJECTIVE: Pain is common in older individuals. In order to understand and treat pain in this group, reliable and valid measures are needed. This study aimed to evaluate: (1) the validity, utility, incorrect response rates and preference rates of 5 pain rating scales in older individuals; and (2) the associations between age, education level, and cognitive function and both (a) incorrect response and (b) preference rates.
METHODS: Two hundred and one orthopedic clinic outpatients ≥ 65 years old were asked to rate their current pain, and least, average, and worst pain intensity in the past week using 5 scales: Verbal Numerical Rating Scale (VNRS), Faces Pain Scale - Revised (FPS-R), Verbal Rating Scale (VRS), Numerical Rating Scale (NRS), and Visual Analogue Scale (VAS). Participants were also asked to indicate scale preference. We computed the associations between each measure and a factor score representing the shared variance among the scales, the incorrect response and scale preference rates, and the associations between incorrect response and preference rates and age, education level, and cognitive function. The incorrect responses included being unable to respond, providing more than one response, responses outside a range, providing range answers rather than fixed answers, and responses indicating \'least > average,\' \'least > worst,\' and \'average > worst\'.
RESULTS: The findings support validity of all 5 scales in older individuals who are able to use all measures. The VNRS had the lowest (2%) and the VAS had the highest (6%) incorrect response rates. The NRS was the most (35%) and the VAS was the least (5%) preferred. Age was associated with the incorrect response rates of the VRS and VAS, such that older individuals were less likely to use these scales correctly. Education level was associated with the incorrect response rates of the FPS-R, NRS and VAS, such that those with less education were less likely to use these measures correctly. Cognitive function was not significantly associated with incorrect response rates. Age, education level and cognitive function were not significantly associated with scale preference.
CONCLUSIONS: Although all five scales are valid, the VNRS evidences the best overall utility in this sample of older individuals with pain. The NRS or FPS-R would be fine alternatives if it is not practical or feasible to use the VNRS.

Clinicians often ask people with chronic pain about their perceived benefit from interventions designed to improve their pain. The aim of this study is to identify factors that contribute to underestimating or overestimating perceived changes in daily pain intensity over a month of daily assessments. We examined data from individuals with chronic pain who provided at least 28 daily assessments using a pain app as secondary analyses. Participants provided baseline demographic information and completed questionnaires assessing pain, activity interference, mood, pain disability, and catastrophizing. Using the pain app, they entered daily ratings of pain (0=none; 10=worst pain possible) and impressions of perceived day-to-day change (0=better; 5=same; and 10=worse). Two hundred fifty-two (N=252) subjects with chronic pain met the inclusion criteria of completing at least 28 daily assessments. Those who underestimated their improvement tended to have higher pain intensity at baseline (p<0.001), reported greater activity interference and disability p<0.001) and were prone to greater catastrophizing and anxiety and depression (p<0.01). People who were more accurate in assessing their improvement engaged less with the app with fewer 2-way messages compared with those who either underestimated or overestimated their improvement and who had more 2-way messaging (p<0.05). This longitudinal study suggests that those who report greater levels of catastrophizing and anxiety and depression are more likely to underestimate any improvements of their pain over time but seem to engage more with a pain app. Future research will help in our understanding of what magnitude of perceived change in pain ratings is clinically meaningful. PERSPECTIVE: Those who report greater levels of pain, disability, anxiety, depression, and catastrophizing are most prone to underestimate improvements of their pain over time.

UNASSIGNED: Growing pains are the most common cause of musculoskeletal pain in children, affecting both children\'s and caregivers\' well-being. The lack of definitive diagnostic criteria complicates diagnosis and treatment.
UNASSIGNED: This study aims to outline the clinical features and identify factors associated with the frequency and intensity of growing pains in children in Chongqing, China.
UNASSIGNED: A cross-sectional study was conducted in a children\'s hospital using its Internet hospital follow-up platform. Children initially diagnosed with growing pains between July and September 2022 were enrolled. Sociodemographics, pain locations, duration, frequency, intensity, and potentially related factors were collected.
UNASSIGNED: Eight hundred sixty-three children were enrolled (average age: 8.19 ± 3.24 years; 455 boys [52.72%]). Pain frequency was reported as quarterly (62.11%), monthly (24.80%), biweekly (1.74%), weekly (10.08%), and daily (1.27%). The prevalence of mild, moderate, and severe pain was 26.65%, 55.74%, and 17.61%, respectively. The knee was the most common pain location (63.85%), mostly encountered between 4 pm and 5 pm (20.51%). Multivariate analysis revealed that pain frequency negatively correlated with vitamin supplementation during pregnancy, positively correlated with underweight, bad temper, increased exercise, and cold lower extremities. Pain intensity positively correlated with irritability, increased exercise, and pain sensitivity but negatively correlated with age and vitamin supplementation during lactation.
UNASSIGNED: Growing pains typically occur on a quarterly basis, predominantly affecting the knees during 4 pm to 5 pm. Factors in sociodemographics, maternal aspect, temperament, and exercise levels can influence pain frequency and intensity. Clinicians should consider these aspects when developing comprehensive strategies for pain management.

BACKGROUND: Pain is common in individuals with cerebral palsy (CP) and the most reported pain site is the foot/lower leg. We analyzed the prevalence of pain in the foot/lower leg and the associations with age, sex, gross motor function, and clinical findings in individuals with CP.
METHODS: This was a cross-sectional register-study, based on data reported to the Swedish Cerebral Palsy Follow-up Program (CPUP). All participants in CPUP, four years-of-age or older, were included. Pearson chi-square tests and logistic regression were used to analyze the prevalence and degree of pain in the foot/lower leg.
RESULTS: In total, 5,122 individuals were included from the CPUP database: 58% were males and 66% were under 18 years-of-age. Overall, 1,077 (21%) reported pain in the foot/lower leg. The odds ratios (ORs) of pain were higher in females (OR 1.31, 95% confidence interval (CI) 1.13-1.53), individuals who could ambulate (Gross Motor Function Classification System Level I (OR 1.84, CI 1.32-2.57) and II (OR 2.01, CI 1.46-2.79) compared to level V), and in individuals with decreased range of motion of the ankle (dorsiflexion 1-10 degrees (OR 1.43, CI 1.13-1.83) and ≤ 0 degrees (OR 1.46, CI 1.10-1.93) compared to ≥ 20 degrees). With increasing age the OR of pain increased (OR 1.02, CI 1.01-1.03) as well as the reported pain intensity (p < 0.001).
CONCLUSIONS: Pain in the foot and lower leg appears to be a significant problem in individuals with CP, particularly in those who walk. As with pain in general in this population, both pain intensity and frequency increase with age. The odds of pain in the foot and lower leg were increased in individuals with limited dorsiflexion of the ankle. Given the cross-sectional design causality cannot be inferred and it is unknown if pain causes decreased range of motion of the ankle or if decreased range of motion causes pain. Further research is needed on causal pathways and importantly on prevention.

Adequate pain control after total knee arthroplasty (TKA) has been associated with improved patient mobility and satisfaction, and is a task that has historically relied on opioids. Multimodal analgesic regimens can be considered a therapeutic alternative for postoperative pain control to avoid opioid consumption and its adverse side effects. This study aimed to evaluate the use of a multimodal analgesia protocol based on nonsteroidal anti-inflammatory drugs (NSAIDs) and acetaminophen as an alternative to reduce opioid consumption in Hispanic patients undergoing primary TKA.
UNASSIGNED: An institutional review board-approved, randomized controlled trial evaluated postoperative pain control after TKA in a Hispanic population. The experimental opioid-sparing group received 30-mg ketorolac intravenously every 6 hours and 1-g acetaminophen orally every 6 hours as the patient requested. The experimental group had the option to use morphine and oxycodone combined with acetaminophen as a rescue therapy. The control group received opioids in the form of 0.1-mg/kg morphine intravenously every 6 hours and/or oxycodone combined with acetaminophen (2.5 and 325 mg), 2 tablets orally every 6 hours, as the patient requested. Sociodemographic, operative, and immediate postoperative data and pain intensity measurements according to the numerical rating scale (NRS) were compared between groups. Analgesic efficacy was assessed according to the NRS scores at 12, 24, and 48 hours postoperatively.
UNASSIGNED: Eighty-one Hispanic patients met inclusion criteria: 42 patients in the experimental group and 39 patients in the control group. None of the patients in the experimental group requested oxycodone combined with acetaminophen as a rescue therapy. Only 2 patients in the experimental group used a mean of 3.0 ± 1.4 mg of rescue morphine; in comparison, the control group consumed a mean of 28.0 ± 7.9 mg of morphine and 64.8 ± 26.0 mg of oxycodone per patient. A pain intensity decrease was observed in the experimental and control groups, with no postoperative evaluation differences at 12 hours (6.7 ± 2.9 compared with 5.9 ± 2.8; p = 0.209), 24 hours (6.2 ± 2.0 compared with 6.1 ± 2.2; p = 0.813), and 48 hours (4.7 ± 2.1 compared with 4.6 ± 1.7; p = 0.835).
UNASSIGNED: The use of a multimodal analgesic regimen based on intravenous ketorolac and oral acetaminophen was adequate in reducing postoperative pain and opioid consumption in Hispanic patients undergoing TKA.
UNASSIGNED: Therapeutic Level I. See Instructions for Authors for a complete description of levels of evidence.

BACKGROUND: Recent clinical studies confirmed that whole-body electromyostimulation (WB-EMS) training is a safe and time-efficient therapeutic method for patients with nonspecific chronic back pain (NSCBP). However, significant variations in initial pain intensity among subjects in these studies have been observed. This study aims to determine if patients with differing initial pain intensities experience varying degrees of benefit from WB-EMS and to assess the overall correlation between initial pain levels and pain reduction.
METHODS: Pain intensity datasets from two studies were combined. The pooled data included 121 NSCBP patients (38 males and 83 females) with an average age of 55.1 years (±11.8 years). Data was categorized by baseline pain intensity on the numeric rating scale (NRS) into seven groups: 0 to 2, >2 to 3, >3 to 4, >4 to 5, >5 to 6, >6 to 7, and >7. Both absolute and relative changes were analyzed. Additionally, a Spearman rho correlation test was performed on the entire dataset to evaluate the relationship between initial pain level and pain reduction.
RESULTS: Significant improvements were noted across all NRS11 categories, with strong effect sizes (p) in all classes above 2, ranging from 0.56 to 0.90. The >7 category exhibited the highest rate of clinically significant changes (80%) and an average improvement of 3.72 points. The overall group from >1 to 10 showed an average improvement of 1.33 points, with 37% of the participants experiencing clinically significant improvements. The Spearman rho correlation test revealed a moderate positive relationship between initial pain level and pain reduction (r_s = 0.531, p < 0.001), indicating that, generally, higher initial pain levels are associated with greater pain reduction.
CONCLUSIONS: The findings support the hypothesis that NSCBP patients with higher baseline NRS values benefit more substantially from WB-EMS. Those with NRS values above 7 show the greatest improvement and highest rate of clinical significance. The overall positive correlation between initial pain intensity and pain reduction further underscores the efficacy of WB-EMS in managing NSCBP across different pain intensities.

OBJECTIVE: Pain is increasingly becoming common among middle-aged and older adults. While research on the association between pain characteristics and sleep problems (SP) is limited in low- and middle-income countries, the underlying mechanisms of the association are poorly understood. This study examines the association of bodily pain intensity and pain interference with SP and investigates the mediating role of activity limitation and emotional distress in this association.
METHODS: We analyzed population-based data, including 1,201 individuals aged ≥50 (mean [SD] age 66.14 [11.85] years) from the 2016-2018 AgeHeaPsyWel-HeaSeeB study in Ghana. Multiple OLS regressions and serial multiple mediation modeling using bootstrapping analyses examined direct and indirect effects from pain to SP through activity limitation and emotional distress.
RESULTS: Regressions demonstrated that pain intensity and interference were significantly associated with higher levels of activity limitation, emotional distress, and SP (range: β = 0.049-0.658). Bootstrapping analysis showed that activity limitation and emotional distress serially mediated the relationship between pain intensity and SP (total effect: β = 0.264, Bootstrap 95% confidence interval [CI] = 0.165-0.362; direct effect: (β = 0.107, Bootstrap 95% CI = 0.005-0.210; total indirect effect: β = 0.156, Bootstrap 95% CI = 0.005-0.210) accounting for ∼59%. Activity limitation and emotional distress mediated pain interference and SP association (total effect: β = 0.404, Bootstrap 95% CI = 0.318-0.490; direct effect: β = 0.292, Bootstrap 95% CI = 0.201-0.384; and total indirect effect: β = 0.112, Bootstrap 95% CI = 0.069-0.156) yielding ∼28%.
CONCLUSIONS: Our data suggest that activity limitation and emotional distress may convey stress-related risks of pain on SP. Future research should evaluate if activity limitation and emotional distress could be effective targets to reduce the effect of pain on sleep in later-life.

OBJECTIVE: This study aimed to explore the pathways between family functioning and mental health in people with neuropathic pain, as well as to discuss the mediating role of pain intensity, self-perceived burden, pain catastrophizing, and functional status.
METHODS: Cross-sectional design reported using the STROBE guidelines.
METHODS: A total of 277 people with neuropathic pain completed face-to-face questionnaires to evaluate family functioning, pain intensity, pain catastrophizing, self-perceived burden, functional status, and mental health. Structural equation modeling (SEM) was constructed to analyze the pathways between these variables.
RESULTS: The positive total effect between family functioning and mental health was significant and partially mediated by self-perceived burden, pain catastrophizing, and functional status. In addition, better family functioning was associated with higher pain intensity, which worsens self-perceived burden, pain catastrophizing, and functional status, masking 23.68% of the positive effects between family functioning and mental health.
CONCLUSIONS: Better family functioning was associated with better mental health, as explained by reduced self-perceived burden, reduced pain catastrophizing, and improved functional status. However, this benefit may be partially masked by the relationship that better family functioning explains higher pain intensity.
CONCLUSIONS: Nurses\' comprehensive assessment and management of neuropathic pain from both the family and individual levels, such as family functioning, pain intensity, self-perceived burden, pain catastrophizing, and functional status, may be beneficial in promoting patients\' mental health. In addition, it is necessary to identify why good family functioning is associated with higher pain intensity and intervene in this regard.
