Abstract
Rating scales are commonly used in psychological research and practice. It is important to consider how different item response options used on rating scales, such as those based on frequency or severity, may affect how they measure psychological constructs. In this study, participants were randomly assigned to conditions where they completed two depression and two generalized anxiety rating scales that used either frequency or severity item response options. Descriptive statistics and reliability estimates across depression and generalized anxiety scales using different item response options were similar. Measurement invariance tests indicated that depression and generalized anxiety scales with different item response options could be considered practically invariant. Finally, depression and generalized anxiety scales with different item response options had similar correlations with measures of impairment and other psychological constructs. There were essentially no differences in psychometric and measurement properties of these depression and generalized anxiety scales when using different item response options, suggesting this may not substantially affect the measurement of these constructs.

Yoo H, Cho Y, Cho S. Does past/current pain change pain experience? Comparing self-reports and pupillary responses. Front Psychol 2023; 14:1094903. [PMID: 36874838 PMCID: PMC9982106 DOI: 10.3389/fpsyg.2023.1094903] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Accepted: 01/18/2023] [Indexed: 02/19/2023] Open
Abstract
Introduction For decades, a substantial body of research has confirmed the subjective nature of pain. Subjectivity seems to be integrated into the concept of pain but is often confined to self-reported pain. Although it seems likely that past and current pain experiences would interact and influence subjective pain reports, the influence of these factors has not been investigated in the context of physiological pain. The current study focused on exploring the influence of past/current pain on self-reporting and pupillary responses to pain. Methods Overall, 47 participants were divided into two groups, a 4°C-10°C group (experiencing major pain first) and a 10°C-4°C group (experiencing minor pain first), and performed cold pressor tasks (CPT) twice for 30 s each. During the two rounds of CPT, participants reported their pain intensity, and their pupillary responses were measured. Subsequently, they reappraised their pain ratings in the first CPT session. Results Self-reported pain showed a significant difference (4°C-10°C: p = 0.045; 10°C-4°C: p < 0.001) in the rating of cold pain stimuli in both groups, and this gap was higher in the 10°C-4°C group than in the 4°C-10°C group. In terms of pupillary response, the 4°C-10°C group exhibited a significant difference in pupil diameter, whereas this was marginally significant in the 10°C-4°C group (4°C-10°C: p < 0.001; 10°C-4°C: p = 0.062). There were no significant changes in self-reported pain after reappraisal in either group. Discussion The findings of the current study confirmed that subjective and physiological responses to pain can be altered by previous experiences of pain.

Experiences of recovery and a new care pathway for people with pain after total knee replacement: qualitative research embedded in the STAR trial. BMC Musculoskelet Disord 2022; 23:451. [PMID: 35562815 PMCID: PMC9103301 DOI: 10.1186/s12891-022-05423-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/24/2021] [Accepted: 05/10/2022] [Indexed: 11/23/2022] Open
Abstract
Background Approximately 20% of people experience chronic postsurgical pain after total knee replacement. The STAR randomised controlled trial (ISCRTN92545361) evaluated the clinical- and cost-effectiveness of a new multifaceted and personalised care pathway, compared with usual care, for people with pain at three months after total knee replacement. We report trial participants’ experiences of postoperative pain and the acceptability of the STAR care pathway, which consisted of an assessment clinic at three months, and up to six follow-up telephone calls over 12 months. Methods Semi-structured interviews were conducted with 27 people (10 men, 17 women) between February 2018 and January 2020. Participants were sampled purposively from the care pathway intervention group and interviewed after completion of the final postoperative trial questionnaire at approximately 15 months after knee replacement. Interviews were audio-recorded, transcribed, anonymised and analysed using inductive thematic analysis. Findings Many participants were unprepared for the severity and impact of postoperative pain, which they described as extreme and constant and that tested their physical and mental endurance. Participants identified ‘low points’ during their recovery, triggered by stiffening, pain or swelling that caused feelings of anxiety, depression, and pain catastrophising. Participants described the STAR assessment clinic as something that seemed “perfectly normal” suggesting it was seamlessly integrated into NHS care. Even in the context of some ongoing pain, the STAR care pathway had provided a source of support and an opportunity to discuss concerns about their ongoing recovery. Conclusions People who have knee replacement may be unprepared for the severity and impact of postoperative pain, and the hard work of recovery afterwards. This highlights the challenges of preparing patients for total knee replacement and suggests that clinical attention is needed if exercise and mobilising is painful beyond the three month postoperative period. The STAR care pathway is acceptable to people with pain after total knee replacement.

J Pain Res 2022; 15:181-191. [PMID: 35115822 PMCID: PMC8800870 DOI: 10.2147/jpr.s336485] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2021] [Accepted: 12/23/2021] [Indexed: 11/23/2022] Open
Abstract
Purpose It has been shown that the memory of pain induced by running might be underestimated. Our previous study showed the contribution of emotional factors to this process. This study aimed to investigate the cognitive factors that might influence the memory of this type of pain, ie expectancy of pain intensity, expectancy of pain unpleasantness, and desire for pain relief. Participants and Methods A total of 49 half-marathon runners rated the intensity and unpleasantness of pain immediately after completing a run and one month later. Participants rated the expected intensity and unpleasantness of the upcoming pain before starting the run, as well as the desire for pain relief after its completion. Those who also participated in the previous edition of the half marathon were asked to recall the pain experienced due to that run. Results Participants underestimated remembered pain intensity and unpleasantness. The desire for pain relief mediated the memory of pain intensity (p < 0.05), while expectancy of pain intensity influenced memory of pain intensity (a × b) through its effect on the experienced pain (bootstrapped point estimate = 0.08; 95% CI: 0.02–0.32). The remembered intensity of pain experienced during the previous half marathon affected the current pain experience directly (p < 0.05) or indirectly (a × b) by generating pain-related expectancy (bootstrapped point estimate = 0.11; 95% CI: 0.01–0.46). The cognitive variables did not influence the memory of pain unpleasantness. Conclusion The memory of pain induced by sports activity may change due to cognitive factors; however, further research is needed to investigate their role in shaping the memory of the sensory and affective dimensions of pain.

Abstract
Background Memory and in turn, memory of pain is a reconstructive process. This study considers the relationship between time, memory, affective states, and pain induced by running a marathon by investigating the influence of these factors on a participant’s memory of pain experienced after a marathon. The following two hypotheses were formulated: 1) participants’ recalled-pain of marathon experience is underestimated; and 2) the underestimation of recalled pain would be greater for participants experiencing higher positive affect. Methods A longitudinal design was employed to check pain intensities of marathon participants a) at the finish line and b) 6 months following its completion. The sample size was based on a power analysis, and 108 marathonists rated their pain intensities and positive and negative affects at the finish line. From this sample, 58 participants recalled their pain experience of running the marathon 6 months later. Linear models, including computer-based data-mining algorithms, were used. Results The experienced pain was higher than their recalled pain (t(55) = 3.412, p < 0.01, d = 0.45), supporting the first hypothesis. The memory of pain faded similarly in all participants, which did not directly support the second hypothesis. Further exploratory analysis suggested that negative and positive affective states were related to participants’ pain memory; positive affective states appeared to be inversely related to the recall (β = −0.289, p = 0.039). Discussion This study shows that time has a significant effect on memory recall and that emotions may also influence the memory of pain. This is the first study that preliminarily showcased the effect of positive affective states on the memory of pain induced by physical exercise.

Increased Work from Home and Low Back Pain among Japanese Desk Workers during the Coronavirus Disease 2019 Pandemic: A Cross-Sectional Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph182312363. [PMID: 34886088 PMCID: PMC8657068 DOI: 10.3390/ijerph182312363] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/12/2021] [Revised: 11/20/2021] [Accepted: 11/22/2021] [Indexed: 12/19/2022]
Abstract
To prevent the spread of coronavirus disease 2019 (COVID-19), desk workers in Japan have been encouraged to work from home. Due to rapidly increased working from home, working in environments that are not properly designed and working with poor posture can affect low back pain (LBP). This study aimed to examine the relationship between increased work from home during the COVID-19 pandemic and LBP among Japanese desk workers. Using study data from the Japan COVID-19 and Society Internet Survey 2020 conducted from August to September 2020, 4227 desk workers who did not have LBP before the COVID-19 pandemic were analyzed out of 25,482 total respondents. Odds ratios (ORs) and 95% confidence intervals (CIs) for LBP were calculated by multivariable logistic regression, adjusting for covariates such as socioeconomic factors. During the COVID-19 pandemic, 31.3% of desk workers with an increased chance of working from home, and 4.1% had LBP. Desk workers with increased working from home were more likely to have LBP (OR: 2.00 (95% CI, 1.36–2.93)). In this large-scale study, increased work from home was associated with LBP among desk workers during the COVID-19 pandemic. Therefore, preparing an appropriate work environment for desk workers working from home can improve productivity, leading to positive effects.

Abstract
Background Patient outcomes and experience during a Spinal Cord Stimulation (SCS) screening trial can have a significant effect on whether to proceed with long-term, permanent implantation of an SCS device for the treatment of chronic pain. Enhancing the ability to track and assess patients during this initial trial evaluation offers the potential for improved understanding regarding the suitability of permanent device implantation as well as identification of the SCS-based neurostimulative modalities and parameters that may provide substantial analgesia in a patient-specific manner. Objective In this report, we aimed to describe a preliminary, real-world assessment of a new, real time tracking, smart, device-based digital app used by patients with chronic pain undergoing trial screening for SCS therapy. Methods This is a real-world, retrospective evaluation of 13,331 patients diagnosed with chronic pain who used the new “mySCS” mobile app during an SCS screening trial. The app design is health insurance portability and accountability act (HIPAA)-compliant and compatible with most commercially available smartphones (eg, Apple, iPhone, and Android). The app enables tracking of user-inputted health-related responses (ie, pain relief, activity level, and sleep quality) in addition to personal trial goals and a summary of overall experience during the SCS trial. A deidentified, aggregate analysis of user engagement, user-submitted responses, and overall trial success was conducted. Results When provided the opportunity, the percentage of users who engaged with the tracking app for ≥50% of the time during their trial was found to be 64.43% (n=8589). Among the 13,331 patients who used the app, 58.24% (n=7764) entered a trial goal. Most patients underwent SCS screening with a trial duration of at least 7 days (n=7739, 58.05%). Of those patients who undertook a 7-day SCS trial, 62.30% (n=3456) engaged the app for 4 days or more. In addition, among all who submitted descriptive responses using the app, health-related improvements were reported by 77.84% (n=10,377) of patients who reached day 3 of the screening phase assessment and by 83.04% (n=11,070) of those who reached trial completion. A trial success rate of 91% was determined for those who used the app (versus 85% success rate for nonusers). Conclusions Data from this initial, real-world examination of a mobile, digital-health–based tracking app (“mySCS”), as used during the SCS screening phase, demonstrate that substantial patient engagement can be achieved while also providing for the acquisition of more real time patient-outcome measures that may help facilitate improved SCS trial success.

Abstract
OBJECTIVE The primary objective of this study was to compare the association between cardiac surgical approach (thoracotomy vs. sternotomy) and incidence of persistent postoperative pain at 3 months. Secondary objectives were the incidence and intensity of persistent pain at 6 and 12 months, acute postoperative pain, analgesic requirement and its side effects. DESIGN Single-center, prospective, observational study. Recruitment between December 2017 and August 2018. SETTING Perioperative care at university-affiliated tertiary care centre. PATIENTS 202 adults scheduled for cardiac surgery. Patients with chronic pain or behavioural disorder were excluded. INTERVENTIONS Thoracotomy (n = 106) and sternotomy (n = 96). MEASUREMENTS Pain scores and pain medication requirements from extubation until hospital discharge. Persistent postoperative pain was assessed using a telephone questionnaire. MAIN RESULTS Incidence and intensity of pain was not significantly different between thoracotomy or sternotomy either in the short- or in the long-term follow-up. Incidence of persistent postoperative pain showed no differences between groups (30.2 vs 22.9% at 3 months (p = 0.297), 10.4 vs 7.3% at 6 months (p = 0.364) and 7.5 vs 7.3% at 12 months (p = 0.518) in thoracotomy and sternotomy group). A significant decrease of pain incidence was observed between 3 and 6 months (p < 0.001) but not between 6 and 12 months (p = 0.259) in both groups. ANOVA of repeated measures adjusted for confounding variable showed a decrease of acute pain intensity over time (p = 0.001) with no difference between groups (p = 0.145). Acute pain medication requirements were not different between the groups (p = 0.237 for piritramide and p = 0.743 for oxycodone) with no difference in their side effects. CONCLUSIONS Our study showed no difference in short- or long-term pain in patients undergoing anterolateral thoracotomy or median sternotomy. Both groups showed a decrease in persistent postoperative pain incidence between 3 and 6 months without any significant changes at 12 months.

Abstract
Background Smartwatches enable physicians to monitor symptoms in patients with knee osteoarthritis, their behavior, and their environment. Older adults experience fluctuations in their pain and related symptoms (mood, fatigue, and sleep quality) that smartwatches are ideally suited to capture remotely in a convenient manner. Objective The aim of this study was to evaluate satisfaction, usability, and compliance using the real-time, online assessment and mobility monitoring (ROAMM) mobile app designed for smartwatches for individuals with knee osteoarthritis. Methods Participants (N=28; mean age 73.2, SD 5.5 years; 70% female) with reported knee osteoarthritis were asked to wear a smartwatch with the ROAMM app installed. They were prompted to report their prior night’s sleep quality in the morning, followed by ecological momentary assessments (EMAs) of their pain, fatigue, mood, and activity in the morning, afternoon, and evening. Satisfaction, comfort, and usability were evaluated using a standardized questionnaire. Compliance with regard to answering EMAs was calculated after excluding time when the watch was not being worn for technical reasons (eg, while charging). Results A majority of participants reported that the text displayed was large enough to read (22/26, 85%), and all participants found it easy to enter ratings using the smartwatch. Approximately half of the participants found the smartwatch to be comfortable (14/26, 54%) and would consider wearing it as their personal watch (11/24, 46%). Most participants were satisfied with its battery charging system (20/26, 77%). A majority of participants (19/26, 73%) expressed their willingness to use the ROAMM app for a 1-year research study. The overall EMA compliance rate was 83% (2505/3036 responses). The compliance rate was lower among those not regularly wearing a wristwatch (10/26, 88% vs 16/26, 71%) and among those who found the text too small to read (4/26, 86% vs 22/26, 60%). Conclusions Older adults with knee osteoarthritis positively rated the ROAMM smartwatch app and were generally satisfied with the device. The high compliance rates coupled with the willingness to participate in a long-term study suggest that the ROAMM app is a viable approach to remotely collecting health symptoms and behaviors for both research and clinical endeavors.

Abstract
BACKGROUND Spinal pain is an important public health issue that brings biopsychosocial problems. Global Postural Re-education (GPR) is one of its treatments. OBJECTIVE Evaluate the effects of GPR on pain, flexibility, and posture of individuals with non-specific low back pain and/or neck pain for more than six weeks. METHODS The study enrolled 18 individuals, which were randomized into two groups: GPR group (GPRG; n= 09), submitted to 10 sessions of GPR and control group (CG; n= 09), not submitted to any technique. The evaluations were done before and after the GPRG sessions, for pain perception (Visual Analogue Scale - VAS), flexibility (finger-floor test) and posture (SAPO). The re-evaluation was done in the GPRG after the end of 10 treatment sessions and, in the GC, after the time equivalent to 10 sessions. The level of significance was set at p< 0.05. RESULTS This pilot study has no homogeneity between groups. GPRG presented improvement in pain and flexibility, but showed no changes in posture. In the CG, there was no difference in the variables evaluated in this study. CONCLUSION GPR had positive effects on pain and flexibility, but did not present a significant effect on posture.

METHODS Retrospective cohort study of patients who underwent laparoscopic/open appendectomies, laparoscopic/open cholecystectomies, and laparoscopic/open inguinal hernia repair during a 6-month interval in 2018 (control), 2019 (post-policy intervention), and 2020 (post-institutional intervention) to assess changes in postoperative opioid prescribing patterns. A survey was collected for the 2020 cohort. RESULTS Comparing the 762 patients identified in 2018, 2019, and 2020 cohorts there was a significant decrease in mean opioid tabs prescribed (23.5 ± 8.9 vs. 16.2 ± 7.0 vs. 12.8 ± 4.9, p < 0.01) and mean OME dosage (148.0 ± 68.0 vs. 108.6 ± 51.8 vs. 95.4 ± 38.0, p < 0.01), without a difference in refill requests. Patient survey (response rate 63%) indicated 91.4% of patients reported sufficient pain control. CONCLUSION Formalized opioid-prescribing guidelines and statewide regulations can significantly decrease postoperative opioid prescribing with good patient satisfaction. Surgeon education may facilitate efforts to minimize narcotic over-prescription without compromising pain management.

Impact of COVID-19Quarantine on Low Back Pain Intensity, Prevalence, and Associated Risk Factors among Adult Citizens Residing in Riyadh (Saudi Arabia): A Cross-Sectional Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17197302. [PMID: 33036287 PMCID: PMC7579188 DOI: 10.3390/ijerph17197302] [Citation(s) in RCA: 54] [Impact Index Per Article: 13.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/03/2020] [Revised: 09/20/2020] [Accepted: 09/28/2020] [Indexed: 12/11/2022]
Abstract
This study aimed to estimate the effect of the coronavirus disease 2019 (COVID-19) quarantine on low back pain (LBP) intensity, prevalence, and associated risk factors among adults in Riyadh (Saudi Arabia). A total of 463 adults (259 males and 204 females) aged between 18 and 64 years and residing in Riyadh (Saudi Arabia) participated in this cross-sectional study. A self-administered structured questionnaire composed of 20 questions regarding demographic characteristics, work- and academic-related aspects, physical activity (PA), daily habits and tasks, and pain-related aspects was used. The LBP point prevalence before the quarantine was 38.8%, and 43.8% after the quarantine. The LBP intensity significantly increased during the quarantine. The low back was also the most common musculoskeletal pain area. Furthermore, during the quarantine, a significantly higher LBP intensity was reported by those individuals who (a) were aged between 35 and 49 years old, (b) had a body mass index equal to or exceeding 30, (c) underwent higher levels of stress, (d) did not comply with the ergonomic recommendations, (e) were sitting for long periods, (f) did not practice enough physical activity (PA), and (g) underwent teleworking or distance learning. No significant differences were found between genders. The COVID-19 quarantine resulted in a significant increase in LBP intensity, point prevalence, and most associated risk factors.

Abstract
Objective The pain numerical rating scale (NRS) is widely used in pain research and clinical settings to represent pain intensity. For an individual with chronic pain, NRS reporting requires representation of a complex subjective state as a numeral. To evaluate the process of NRS reporting, this study examined the relationship between reported pain NRS levels and imagined painful events reported by study subjects. Design A total of 149 subjects with chronic low back pain characterized by the NIH Research Task Force Recommended Minimal Dataset reported current pain NRS and provided imagined examples of painful experiences also attributing to these an NRS. We present a quantitative and qualitative analysis of the 797 pain examples provided by the study subjects. Results Study subjects tended to be able to imagine both highly painful 10/10 events and non-painful events with relative agreement across subjects. While NRS for the pain examples tended to increase with example severity, for many types of examples there was wide dispersion around the mean pain level. Examination of pain examples indicated unexpected relationships between current pain and the intensity and nature of the imagined painful events. Conclusions Our results indicate that the pain NRS does not provide a reliably interpretable assessment of current physical pain intensity for an individual with chronic pain at a specific moment.

Abstract
Cluster headache (CH), a severe primary headache, is often misdiagnosed and mismanaged. The aim of this study was to develop and evaluate a screening tool to aid the diagnosis of CH. We developed a novel 12-item screening tool. This was comprised of four components: (1) images depicting headache pain; (2) pain descriptors; (3) key questions that could differentiate between CH and migraine; and (4) a visual analogue pain scale. The total possible questionnaire score ranged from 3-32. Patients with CH and migraines (control group) were recruited prospectively from a headache centre in the North of England, UK. Two-hundred and ninety-six patients were included in the study: 81 CH patients, 36 of which suffer with episodic CH and 45 with chronic CH; 215 migraine patients, 92 of which suffer with episodic migraine and 123 with chronic migraine. The mean questionnaire score was higher in CH patients versus migraine patients (28.4 versus 19.5). At a cut-off score of >25 out of 32, the screening tool had a sensitivity of 86.4% and a specificity of 92.0% in differentiating between CH and migraine. The screening tool could be a useful instrument to aid the diagnosis of a CH. The images depicting headache pain do not clearly discriminate between CH and migraine.

Abstract
BACKGROUND Changes over time to self-managed chronic pain treatments are not a routine part of pain management discussions and might provide insight into adjustments that improve pain outcomes. AIMS The purpose of this study was to develop and test an electronic pain management life history calendar (ePMLHC) for use with older adults with chronic pain. DESIGN An instrument development design was used to develop and test the ePMLHC. METHODS Twenty-four community-dwelling older adults with osteoarthritis pain completed the ePMLHC describing their pain treatment regimens and treatment response history. Accuracy of the ePMLHC data was examined through post-ePMLHC audiorecorded interviews, with the older adults describing their pain treatment history. Feedback on use of the ePMLHC was also measured. An iterative process was used to refine and retest the ePMLHC. The final ePMLHC version was examined with the remaining 12 older adults. RESULTS Significant differences between data reported via the ePMLHC and interviews did not support feasibility of independently reported data via the ePMLHC. Older adults reported that completing the ePMLHC helped them more fully self-reflect on their pain self-management. CONCLUSIONS The ePMLHC has the potential to enhance communication about past pain management treatments and promote more personalized pain treatment regimens, but further development is required.

Abstract
Background and objective Pain, a symptom often present in patients with Chronic Obstructive Pulmonary Disease (COPD), alters quality of life. COPD exacerbation augments several mechanisms that may cause pain (dyspnea, hyperinflation and inflammation) and therefore we hypothesized that pain might be increased during exacerbation. Methods A prospective cohort study was conducted in patients admitted for acute exacerbations of COPD (AECOPD) in two emergency departments in France and Canada. Patients with cancer-related pain or recent trauma were not included. The Short Form McGill Pain Questionnaire (SF-MPQ) and the Brief Pain Inventory (BPI) scale were used to evaluate pain intensity and location. Patients also completed the Borg Dyspnea Scale and Hospital Anxiety and Depression Scale. The questionnaires were completed again during an outpatient assessment in the stable phase. The primary outcome was difference in pain intensity (SF-MPQ) between the exacerbation and stable phases. Results Fifty patients were included. During exacerbation, 46 patients (92%) reported pain compared to 29 (58%) in the stable phase (p<0.001). Pain intensity was higher during exacerbation (SF-MPQ 29.7 [13.6–38.2] vs. 1.4 [0.0–11.2]; p<0.001). Pain was predominantly located in the chest during exacerbation and in the limbs during the stable phase. Pain intensity during exacerbation correlated with anxiety score. Conclusion The frequency and intensity of pain were higher during AECOPD, with a specific distribution. Pain should therefore be routinely assessed and treated in patients with AECOPD.

Med Hypotheses 2019; 128:86-90.

Abstract
Pain can be overestimated, underestimated or reported accurately at recall. The way pain is remembered seems to depend on certain factors, including the type of pain or, in other words, its cause, the context, and the meaning it has for the person suffering from it. For instance, episodes of chronic pain, as well as pain related to surgery, are often overestimated at recall. Interestingly, research shows that pain induced by parturition or marathon running is often underestimated at recall despite the fact that both are not only physically grueling but also emotionally intense experiences. However, both processes can likewise be considered positive events, as opposed to most that involve pain. On the neurophysiological level, one of the similarities between giving birth and running a marathon is the particular involvement of the oxytocin system. Oxytocin is involved both in parturition and intense exercise, for various reasons. During labor, oxytocin mediates uterine contractions, while in the case of extensive running it might be involved in the maintenance of fluid balance. It also has well-documented analgesic properties and plays an important role in memory formation and recall. It has been suggested that oxytocin modulates the output of the central nucleus of the amygdala (CeA) during the fear recall. Moreover, it has been demonstrated that oxytocin can impair fear learning and influence the memory of both positive and negative emotionally salient stimuli. We propose that the reason for pain to be remembered in a more favorable light is the central action of oxytocin in the central nucleus of the amygdala, first and foremost during the encoding phase.

Perception of Older Adults Toward Smartwatch Technology for Assessing Pain and Related Patient-Reported Outcomes: Pilot Study. JMIR Mhealth Uhealth 2019; 7:e10044. [PMID: 30912756 PMCID: PMC6454335 DOI: 10.2196/10044] [Citation(s) in RCA: 38] [Impact Index Per Article: 7.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2018] [Revised: 11/09/2018] [Accepted: 01/06/2019] [Indexed: 12/23/2022] Open
Abstract
Background Chronic pain, including arthritis, affects about 100 million adults in the United States. Complexity and diversity of the pain experience across time and people and its fluctuations across and within days show the need for valid pain reports that do not rely on patient’s long-term recall capability. Smartwatches can be used as digital ecological momentary assessment (EMA) tools for real-time collection of pain scores. Smartwatches are generally less expensive than smartphones, are highly portable, and have a simpler user interface, providing an excellent medium for continuous data collection and enabling a higher compliance rate. Objective The aim of this study was to explore the attitudes and perceptions of older adults towards design and technological aspects of a smartwatch framework for measuring patient report outcomes (PRO) as an EMA tool. Methods A focus group session was conducted to explore the perception of participants towards smartwatch technology and its utility for PRO assessment. Participants included older adults (age 65+), with unilateral or bilateral symptomatic knee osteoarthritis. A preliminary user interface with server communication capability was developed and deployed on 10 Samsung Gear S3 smartwatches and provided to the users during the focus group. Pain was designated as the main PRO, while fatigue, mood, and sleep quality were included as auxiliary PROs. Pre-planned topics included participants’ attitude towards the smartwatch technology, usability of the custom-designed app interface, and suitability of the smartwatch technology for PRO assessment. Discussions were transcribed, and content analysis with theme characterization was performed to identify and code the major themes. Results We recruited 19 participants (age 65+) who consented to take part in the focus group study. The overall attitude of the participants toward the smartwatch technology was positive. They showed interest in the direct phone-call capability, availability of extra apps such as the weather apps and sensors for tracking health and wellness such as accelerometer and heart rate sensor. Nearly three-quarters of participants showed willingness to participate in a one-year study to wear the watch daily. Concerns were raised regarding usability, including accessibility (larger icons), notification customization, and intuitive interface design (unambiguous icons and assessment scales). Participants expressed interest in using smartwatch technology for PRO assessment and the availability of methods for sharing data with health care providers. Conclusions All participants had overall positive views of the smartwatch technology for measuring PROs to facilitate patient-provider communications and to provide more targeted treatments and interventions in the future. Usability concerns were the major issues that will require special consideration in future smartwatch PRO user interface designs, especially accessibility issues, notification design, and use of intuitive assessment scales.

Abstract
STUDY OBJECTIVE To assess how the location of intracavitary lesions during office hysteroscopy influences pain scores. DESIGN Cohort study. SETTING Department of Obstetrics and Gynecology, Hospital das Forças Armadas, Lisbon, Portugal. PATIENTS Two hundred ninety-eight patients undergoing operative office hysteroscopy. INTERVENTIONS Pain intensity was assessed by patients using a numeric rating scale (0-10) 10 minutes after hysteroscopy. MEASUREMENTS AND MAIN RESULTS Statistical analysis assessed the association between pain score and clinical, obstetric, and gynecologic history. Associations with procedure-related factors were also assessed. Lesion location did not influence the perception of pain in the current sample. Hysteroscopic anesthesia allowed for a significant reduction in pain scores, regardless of lesion location. Multivariate analysis revealed that only the type of operative procedure and operating time significantly influenced pain scores. CONCLUSION Hysteroscopic anesthesia allows for a well-tolerated procedure, regardless of lesion location during office hysteroscopy. Lesion location should not be regarded as a technical limitation.

[PMID: 29995638 DOI: 10.1515/sjpain-2018-0070] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2018] [Accepted: 06/20/2018] [Indexed: 11/15/2022]
Abstract
Background and aims Acute pain is differentiated from chronic pain by its sudden onset and short duration; in contrast, chronic pain is characterized by a duration of at least several months, typically considered longer than normal healing time. Despite differences in definition, there is little information on how types of self-management strategies or outcomes differ when pain is chronic rather than acute. Additionally, age and gender are thought to be related to types of strategies used and outcomes. However, strategies used and outcomes can be influenced by level of education, socioeconomic status, occupation, and access to the health care system, which can confound associations to type of pain, age or gender. The purpose of this study was to examine the association of strategies used for pain self-management and outcomes with type of pain, acute or chronic, age, or gender in a socioeconomically homogenous population, pharmacists. Methods Pharmacists with acute or chronic pain and a valid email completed an on-line questionnaire on demographic characteristics, pain characteristics, pharmacological and non-pharmacological strategies for managing pain, and outcomes (e.g. pain intensity). Univariate analysis was conducted by stratifying on type of pain (acute or chronic), then stratifying on gender (men vs. women) and age (younger vs. older). The a priori alpha level was 0.05. Results A total of 366 pharmacists completed the questionnaire, 212 with acute pain (average age=44±12.1; 36% men) and 154 with chronic pain (average age=53±14.0; 48% men). The chronic pain group reported substantially higher levels of pain before treatment, level of post-treatment pain, level of pain at which sleep was possible, and goal pain levels (effect sizes [ES's]=0.37-0.61). The chronic pain group were substantially more likely to use prescription non-steroidal anti-inflammatory medications (NSAIDS), opioids, and non-prescription pain relievers (ES's=0.29-0.80), and non-medical strategies (ES's=0.56-0.77). Participants with chronic pain also were less confident (ES=0.54) and less satisfied (ES=0.52). In contrast, there were no differences within either the acute or chronic pain groups related to gender and outcomes. In the acute pain group, there also were no gender differences related to management strategies. However, younger age in the acute pain group was associated with use of herbal remedies and use of rest. Within the chronic pain group, men were more likely to use NSAIDS and women more likely to use hot/cold packs or massage while older participants were more likely to use massage. Variability in post-treatment level of pain and percent relief was high in all groups (coefficient of variation=25%-100%). Conclusions The differences between acute and chronic pain were substantial and included differences in demographic characteristics, pain characteristics, management strategies used, and outcomes. In contrast, few associations between age and gender with either management strategies or outcomes were identified, although the variability was high. Implications When managing or researching pain management, acute pain should be differentiated from chronic pain. Because of the substantial variability within the gender and age groups, an individual approach to pain management irrespective of age and gender may be most useful.

Abstract
OBJECTIVE Measurement error in predictor variables may threaten the validity of clinical prediction models. We sought to evaluate the possible extent of the problem. A secondary objective was to examine whether predictors are measured at the intended moment of model use. METHODS A systematic search of Medline was used to identify a sample of articles reporting the development of a clinical prediction model published in 2015. After screening according to a predefined inclusion criteria, information on predictors, strategies to control for measurement error, and intended moment of model use were extracted. Susceptibility to measurement error for each predictor was classified into low and high risks. RESULTS Thirty-three studies were reviewed, including 151 different predictors in the final prediction models. Fifty-one (33.7%) predictors were categorized as high risk of error; however, this was not accounted for in the model development. Only 8 (24.2%) studies explicitly stated the intended moment of model use and when the predictors were measured. CONCLUSION Reporting of measurement error and intended moment of model use is poor in prediction model studies. There is a need to identify circumstances where ignoring measurement error in prediction models is consequential and whether accounting for the error will improve the predictions.
