The Relationship Between Approach to Activity Engagement, Specific Aspects of Physical Function, and Pain Duration in Chronic Pain

Understanding the impact of the COVID-19-related lockdown in university workers. Identifying groups through cluster analysis

Objective

To analyse the COVID-19-related lockdown impact on University workers, to identify groups based on this information, and to study the factors associated with each group.

Study design

Cross-sectional study.

Methods

A survey was conducted 3.5 weeks after COVID-19-related lockdown in University workers in Spain. Sociodemographic variables, housing, work, health conditions, levels of anxiety, stress and depression (DASS-21), and social support (MSPSS) were collected. A cluster analysis was performed to identify groups depending on the impact of the lockdown. Differences between groups were tested using Chi-square and Mann-Whitney-U tests, and associated factors with binary logistic regression.

Results

We identified two groups of workers. "G1: Consequences in the daily life routine" was mainly composed of men, Research and Teaching Personnel (RTP) with more stable professional categories, higher income level, and bigger houses than people in G2. Participants in "G2: Concerns for the current and future well-being" presented worse intensity of pain than before the lockdown, more anxiety, depression, stress and less social support than people in G1. ASP (Administration and Services Personnel) had more risk of belonging to G2 than RTP (OR = 5.863). A higher number of people living at home decreased the risk of being in G2 (OR = 0.439). People with lower pain intensity had less risk of being in G2 (OR = 0.014), and this risk decreased as friends support increased (OR = 0.833).

Conclusions

In G1, the consequences were immediately reflected in the stress resulting from changes in their daily work routine. In G2, the concerns were related to their professional future, with worse mental health, greater intensity of pain and less social support.

Cognitive behavioral therapy for an individual suffering from chronic pain with overactivity and sleep disturbance: A case report

Patients suffering from chronic pain (CP) with overactivity frequently experience sleep disturbance. We presented a 35‐year‐old woman suffering from CP. To improve the sleep disturbance of individuals suffering from CP with overactivity, it is important to combine cognitive behavioral therapy for insomnia and activity pacing.

A Qualitative Study of the Impact of the COVID-19 Pandemic on a Sample of Patients With Chronic Pain

This qualitative phenomenological study examined the impact of the COVID-19 pandemic on the lives of patients living with chronic pain. Patients referred to an intensive interdisciplinary pain management program between June 2020 to June 2021 were asked, “How did the COVID-19 pandemic affect your life?” as part of their interdisciplinary assessment. Ninety patients (50 Veterans, 40 civilians) provided comments to this question, which were independently organized into themes using an inductive approach by 4 researchers. Nine main themes emerged: (1) changed psychological state, (2) minimal to no effect, (3) affected personal life activities, (4) changes in accessing care, (5) changes in work/education situation, (6) changes in family dynamics, (7) experiencing more annoyances, (8) COVID-19 pandemic is a barrier to making positive changes, and (9) got COVID-19. Themes are consistent with topics of interest in light of this ongoing, global stressor. Most commonly reported themes reflected changes in psychological well-being and changes in access to care, highlighting similarities between life with chronic pain and life under the pandemic for this group.

Overactivity in Chronic Pain, the Role of Pain-related Endurance and Neuromuscular Activity: An Interdisciplinary, Narrative Review

OBJECTIVES

Decades of research have convincingly shown that fear of pain and pain-related avoidance behavior are important precursors of disability in daily life. Reduced activity as a consequence of avoidance, however, cannot be blamed for chronic disability in all patients. A contrasting behavior, pain-related dysfunctional endurance in a task and overactivity has to be considered. Currently, there is a need to better understand the psychological determinants of overactivity, dysfunctional endurance, and neurobiomechanical consequences.

METHODS

This is a narrative review.

RESULTS

The first part of this review elucidates research on self-reported overactivity, showing associations with higher levels of pain and disability, especially in spinal load positions, for example, lifting, bending, or spending too long a time in specific positions. In addition, measures of habitual endurance-related pain responses, based on the avoidance-endurance model, are related to objective assessments of physical activity and, again, especially in positions known to cause high spinal load (part 2). The final part reveals findings from neuromuscular research on motor control indicating the possibility that, in particular, overactivity and dysfunctional endurance may result in a number of dysfunctional adaptations with repetitive strain injuries of muscles, ligaments, and vertebral segments as precursors of pain.

DISCUSSION

This narrative review brings together different research lines on overactivity, pain-related endurance, and supposed neuromuscular consequences. Clinicians should distinguish between patients who rest and escape from pain at low levels of pain, but who have high levels of fear of pain and those who predominantly persist in activities despite severely increasing pain until a break will be enforced by intolerable pain levels.

Turkish Translation of the Patterns of Activity Measure-Pain in Patients with Chronic Low Back and Neck Pain: Validity and Reliability

OBJECTIVE

To translate the Patterns of Activity Measure-Pain (POAM-P) into Turkish and test its validity and reliability.

METHODS

A total of 252 patients with chronic low back and neck pain were included. The Turkish translation of the POAM-P (POAMP/T), which has subgroups of Avoidance, Overdoing, and Pacing, was performed in accordance with international recommendations. The POAMP/T was administered twice. Physical activity level was assessed with the International Physical Activity Questionnaire-7 (IPAQ-7), and psychologic status was assessed with the Hospital Anxiety (HADS-A) and Depression Scales (HADS-D). The internal and external construct validity, internal consistency, and test-retest reliability were analyzed.

RESULTS

Three related factorial structures were defined in Confirmatory Factor Analysis. Indexes and factor loads were found to be sufficient. A negative relationship was observed between avoidance and IPAQ-7 (rho = -0.328, p < .001), HADS-D (ρ = -0.163, p = .009), and HADS-A scores (ρ = -0.164, p = .009); whereas, a positive relationship was observed between overdoing and IPAQ-7 (ρ = 0.362, p < .001), HADS-D (ρ = 0.309, p < .001), and HADS-A scores (ρ = 0.325, p < .001). A negative correlation was found between pacing and IPAQ-7 (ρ = -0.200, p = .001), HADS-D (ρ = -0.507, p < .001), and HADS-A scores (ρ = -0.509, p < .001). The Cronbach alpha values for avoidance, overdoing, and pacing were obtained as 0.941, 0.917, and 0.940, respectively. The intraclass correlation coefficient for avoidance, overdoing, and pacing was found as 0.972, 0.973, and 0.972, respectively. Test and retest scores were similar (p > .05).

CONCLUSIONS

The Turkish version of the POAM-P is a valid and reliable scale for the assessment of pain-related activity patterns in patients with chronic low back or neck pain.

Overactivity assessment in chronic pain: The development and psychometric evaluation of a multifaceted self-report assessment

Background

Overactivity in the context of chronic pain (i.e. activity engagement that significantly exacerbates pain) is an important clinical issue that has gained empirical attention in the last decade. Current assessment concepts of overactivity tend to focus on frequency to quantify the severity of the pain behaviour. This study aimed to develop and validate a more comprehensive self‐assessment, the Overactivity in Persistent Pain Assessment (OPPA).

Methods

A sample of 333 individuals with chronic pain completed the OPPA. A subset of 202 individuals also completed a set of existing measures of pain‐related outcomes and activity patterns. The remaining 131 participants were provided with a second copy of the OPPA to fill in one week following their initial assessment.

Results

A principal component analysis confirmed that the OPPA items were best represented by a single construct. The OPPA was found to correlate with pain‐related measures in an expected way that is supported by both theory and qualitative data. When compared to existing overactivity measures, the OPPA was the only measure to contribute significantly to the regression models predicting higher levels of pain severity, more pain interference and lower levels of activity participation after controlling for age, gender and activity avoidance. In addition, the OPPA scale exhibited acceptable internal consistency and good test–retest reliability.

Conclusion

The results of this study reinforce the potentially important role of overactivity in the maintenance of pain‐related suffering and supports a corresponding assessment tool with preliminary psychometric evidence for clinical and research applications.

Significance

This study deconstructs the overactivity concept and develop a corresponding assessment based on five quantifiable severity features: severity of pain exacerbation, maladaptive coping strategies used, impact on occupational performance, recovery time and frequency. Results of the psychometric evaluation indicate that this comprehensive assessment of overactivity severity features may be necessary to understand the impact of overactivity on pain severity and physical functioning from both a clinical and research perspective.

Exploring Changes in Activity Patterns in Individuals with Chronic Pain

This longitudinal study explored whether activity patterns change over time in a sample of 56 individuals with chronic musculoskeletal pain over a 15-day period. Once a day, the participants recorded their level of pain intensity and the degree to which they had engaged in several specific activity patterns. Linear mixed models with random coefficients were used to investigate the rate of change in the activity patterns. Age, sex, pain intensity, and pain duration were controlled. The results show that excessive persistence was the only self-reported activity pattern to show a linear change over the 15-day period. There was a decrease in excessive persistence, and this decrease was slower with higher levels of activity avoidance. However, no significant association was found between sex, age, pain intensity, and pain duration and excessive persistence at baseline or change over time. At baseline, a positive association was found between excessive persistence and pain avoidance, pain-related persistence, and pacing to reduce pain, and a negative association was found between excessive persistence and pacing to save energy for valued activities. This result suggests a profile characterized by alternate periods of high and low activity that, in this study, were unrelated to longitudinal changes in pain intensity.

The Relationship Between Daily Physical Activity and Pain in Individuals with Knee Osteoarthritis

Objective

Investigate the association between physical activity and pain severity in individuals with knee osteoarthritis.

Design

Cross-sectional; systematic review with meta-analyses.

Methods

Thirty-one participants with knee osteoarthritis underwent assessment of symptoms via self-report questionnaires and quantitative sensory testing. Following testing, physical activity and symptoms were monitored for seven days using accelerometers and logbooks. Cross-correlation analyses were performed on fluctuations in symptoms and physical activity across the week to detect the relative timing of the strongest association between pain and activity. These data were complemented by meta-analyses of studies that examined correlations between pain from knee osteoarthritis and physical activity or fitness.

Results

Pain severity at baseline correlated with moderate to vigorous physical activity (r2 = 0.161–0.212, P &lt; 0.05), whereby participants who were more physically active had less pain. Conversely, the peak of the cross-correlation analyses was most often positive and lagging, which indicated that pain was increased subsequent to periods of increased activity. These superficially discrepant findings were supported by the results of a meta-analysis of 13 studies and 9,363 participants, which identified significant heterogeneity for associations between physical activity and pain (I2 = 91%). Stronger inverse associations were found between fitness and pain.

Conclusions

Associations between physical activity and pain in people with knee osteoarthritis are variable and dynamic. These results reflect the beneficial impact of an active lifestyle and accompanying higher fitness. Yet, the side effect of acute periods of physical activity to transiently exacerbate pain may influence the behavior of some people to avoid activity because of pain.

Effectiveness of Pacing as a Learned Strategy for People With Chronic Pain: A Systematic Review

Importance: Pacing is a key pain management strategy used by occupational therapy practitioners when working with people with chronic pain. However, there is a paucity of evidence and a lack of consensus regarding the effectiveness of pacing as a pain management strategy for people with chronic pain.

Objective: To evaluate the evidence for the effectiveness of pacing as a learned strategy for people with chronic pain.

Data Sources: Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used to undertake a systematic review. Six databases were searched in March 2016 for randomized controlled trials (RCTs). Combinations of keywords and MeSH terms were used as search terms.

Study Selection and Data Collection: We sought intervention studies that included participants using pacing as a strategy. Studies were assessed for eligibility on the basis of predetermined criteria. Of the 2,820 articles located, 7 RCTs met inclusion criteria.

Findings: Pacing does not reduce the severity of pain or alter psychological traits; however, it can assist in lessening joint stiffness and the interference of fatigue and in decreasing the variability of physical activity.

Conclusions and Relevance: Current evidence supports the delivery of a learned pacing intervention to reduce the interference of fatigue, reduce joint stiffness, and decrease physical activity variability but does not support the use of learned pacing to reduce pain severity. Future research should investigate the effectiveness of pacing as a pain management strategy within the International Classification of Functioning, Disability and Health domains of activity and participation.

What This Article Adds: This systematic review examines existing research on pacing as a learned intervention strategy. The findings will support the clinical reasoning of occupational therapy practitioners, to determine when a learned pacing strategy is indicated, and considerations for how it may be delivered.

Interpersonal behavior in anticipation of pain: a naturalistic study of behavioral mimicry prior to surgery

Current and anticipated pain relate to mimicry behavior in divergent ways, which may bear upon the elicitation of social support during the experience of pain.

Introduction:

Social relationships facilitate coping with pain, but research suggests that it may be difficult to galvanize social support during an episode of acute pain.

Objectives:

The current research examined whether social connections are optimized in the anticipation of pain by observing patients' mimicry of an interaction partner prior to surgery. We hypothesized that when controlling for their current experience of pain, patients' anticipation of pain would be associated with greater mimicry of an interaction partner.

Methods:

Sixty-five patients were interviewed in the waiting room of a maxillofacial surgery unit prior to the removal of an impacted wisdom tooth. Patients' spontaneous mimicry of an interviewer was observed. Patients then rated the quality and intensity of their anticipated pain, as well as the intensity of their current pain and their affective distress.

Results:

Anticipated pain, current pain, and affective distress were positively correlated. Current pain was associated with less frequent mimicry of an interaction partner. The zero-order correlation between anticipated pain and mimicry did not reach conventional levels of significance; however, when controlling for current pain, anticipated pain predicted more frequent mimicry of an interaction partner. The relationship between anticipated pain and mimicry was not explained by affective distress.

Conclusion:

This is the first study to demonstrate that anticipated and current pain relate to behavioral mimicry in divergent ways. Further research is needed to investigate whether the current pattern of results generalizes to other interpersonal behaviors that facilitate social bonds.
