Psychological factors show limited association with the severity of Achilles tendinopathy

BackgroundThis study aimed to investigate the association between psychosocial factors and the severity of Achilles tendinopathy, along with exploring their potential link to the pain's duration. MethodsA cross-sectional study involving 111 individuals with Achilles tendon pain was conducted. Methods: A cross-sectional study involving 111 individuals with Achilles tendon pain was conducted. Various psychological factors were assessed using the Pain Catastrophizing Scale, Chronic Pain Self-Efficacy Scale (CPSS), Tampa Scale for Kinesiophobia, and Hospital Anxiety and Depression Scale (HAD). Additionally, the severity of Achilles tendon pain was evaluated using the Victorian Institute of Sport Assessment-Achilles questionnaire (VISA-A-Br). Regression analyses were employed to determine the association of these psychosocial factors with pain severity and duration. ResultsSelf-efficacy for chronic pain showed a slight association with Achilles tendon pain severity (β = 0.42 [95% CI: 0.06 to 0.16], p = 0.001), explaining only 19% of the dependent variable. The other variables, including anxiety, depression, pain catastrophizing, and fear of movement, did not exhibit significant associations. ConclusionThe study suggests that psychological factors demonstrate limited association with the severity of Achilles tendinopathy. While self-efficacy for chronic pain was weakly associated, its clinical relevance remains uncertain. Future research, particularly longitudinal studies, should explore the influence of psychosocial factors on treatment adherence and response to enhance management strategies for Achilles tendon pain.

A six-participant pilot single-subject study of an individualized pain management program for people with spinal cord injury.

Single-subject repeated measures design. To explore the impacts of a novel individualized interdisciplinary pain self-management program for persons living with spinal cord injury pain. A large rehabilitation institute for adults with physical disabilities in Quebec city (Quebec, Canada). Six persons having sustained a spinal cord injury and experiencing chronic pain participated. Following a five-week pre-intervention phase (baseline repeated measures) and a clinical evaluation, individualized intervention objectives were developed in collaboration with each participant. Then, participants completed a ten-week intensive intervention and a six-month consolidation phase. The program included cognitive behavioral therapy, and physical and pharmacological interventions, which were group- and individual-based. Outcome measures were the Canadian Occupational Performance Measure (COPM), the French-Canadian Chronic Pain Self-efficacy Scale (FC-CPSES), the Brief Pain Inventory (BPI), and the Hospital Anxiety and Depression Scale (HADS). For five out of the six participants, a majority of outcomes improved during either of the intervention phases or both. Improvements in occupational performance were clinically significant for three participants. Pain interference and anxiety improved significantly in five participants, while pain self-efficacy and depressive symptoms improved in four participants. The results suggest that the pain self-management program was effective to reduce the impact of spinal cord injury pain. Further research is needed to replicate these results in a larger study and comprehend the factors favoring or undermining improvements with such programs, as well as their persistence over time.

Merging Yoga and self-management Skills (MY-Skills) to influence self-efficacy among individuals with persistent pain: A pilot study

ContextIndividuals with persistent pain-related disability have lower self-efficacy, which impacts daily function and health. AimTo explore self-efficacy among individuals with persistent pain who were part of a dyad (caregiver and care-recipient) who completed the Merging Yoga and self-management Skills intervention (MY-Skills). MethodsParticipants completed MY-Skills, an 8-week group, dyadic-based self-management and yoga program. Self-efficacy outcomes were collected using the Chronic Pain Self-Efficacy Scale; PROMIS® Self-Efficacy for Managing Daily Activities; and PROMIS® Self-Efficacy for Managing Symptoms. ResultsEight participants completed the study (50.23 ± 14.77 years old, 77% female, (69%) with pain >10 years). Self-efficacy improved across all measures and domains, with significant improvement for physical function self-efficacy (38.97 ± 19.45 vs. 59.10 ± 18.60, p = .004). ConclusionsMY-Skills improved self-efficacy to varying degrees, which may contribute to participants’ confidence in performing activities. Further research is needed to examine dyadic outcomes among caregivers and care-recipients.

Construct validity and reliability of the 2-minute step test in patients with knee osteoarthritis

ObjectiveTo validate and evaluate the intra- and inter-rater reliability of the 2-min step test (2MST) in measuring the functional performance of patients with knee pain associated with osteoarthritis (OA).MethodsForty-one patients with knee OA was included. Two examiners assessed the patients at two times with interval between the test and retest from 7 to 14 days. All executions of 2MST were recorded in real time by the examiners and were also recorded by video. The intraclass correlation coefficient (ICC) and 95% confidence interval (CI), standard error of measurement (SEM) and minimum detectable difference (MDD) were used to determine reliability. In the construct validity, we correlate the score of the 2MST with the other instruments used in the study: The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Numerical Pain Scale (NPS), Pain-Related Catastrophizing Thoughts Scale (PCTS) and Chronic Pain Self-Efficacy Scale (PSEQ). The agreement between the face-to-face assessment and the evaluation based on the video record was assessed using the Bland-Altman methodology in the 4 moments of the 2MST.Results2MST presented excellent intra- (ICC = 0.94, SEM = 4.47, MDD = 12.40) and inter-rater reliability (ICC = 0.97, SEM = 3.07, MDD = 8.52). The agreement was acceptable between face-to-face assessments and the analyzes performed on video. All instruments showed a statistically significant correlation with 2MST, except the PCTS. A correlation magnitude above 0.50 was found between the 2MST and pain and function domains of the WOMAC, and a correlation magnitude between 0.30 and 0.50 with the joint stiffness domain of the WOMAC, NRPS and PSEQ.Conclusion2MST proved to be valid for assessing functional capacity in patients with knee OA, with excellent reliability.

Cognitive, emotional, and somatosensory behavior in professional dancers with acute and chronic pain.

Dance has been linked in a complex manner to pain and the physical and psychological peculiarities of this discipline could influence pain perception and chronicity of pain. To determine the differences in cognitive, emotional, and somatosensory symptoms between dancers with acute versus chronic pain. A cross-sectional study of professional dancers with pain. Higher conservatory of dance. Thirty-four professional dancers experiencing pain were included. The cohort was divided into two subgroups: those with acute pain (<3months duration) and those with chronic pain (>3months duration). Not applicable. Pain intensity (as measured by the visual analogue scale or VAS), pressure pain threshold (PPT), Pain Catastrophizing Scale (PCS), pain-related fear of movement (Tampa Scale of Kinesiophobia [TSK-11]), fear avoidance beliefs (Fear-Avoidance Beliefs Questionnaire [FABQ]), self-efficacy (Chronic Pain Self-Efficacy Scale [CPSS]). and chronic pain severity (Chronic Pain Graded Scale [CPGS]). Dancers with chronic pain reported higher levels of pain intensity in daily activities (p < .01; t=3.42; d =1.17) and during exercise/dance (p=.02; t=2.82; d =0.82), as well as lower PPT in lumbar (p=.03; t=3.22; d =1.1) and tibialis regions (p=.01; t=2.51; d =0.86). Dancers with acute pain experienced worse psychological symptoms indicated by the fear of harm subscale of TSK-11 (p=.04; t=-2.08; d =0.72), physical activity subscale of FABQ (p=.03; t=-2.27; d =0.78), and pain management subscale of CPSS (p=.01; t=-2.76; d =0.94) and lower scores for CPGS scale (p=.01; t=2.99; d =0.7 to 1.26). The results showed differences in pain intensity and PPT revealing higher values in dancers with chronic pain. It is possible that the physical and psychological characteristics of dancers, as well as the sociocultural aspects of this discipline, could influence the way in which this population interprets pain.

Application effect of high-quality nursing model based on hope theory in endometrial cancer patients

Background: To explore the effect of high-quality nursing model based on hope theory in endometrial cancer patients. Methods: The patients (n = 120) with endometrial cancer who underwent surgical treatment in hospital from October 2017 to October 2019 were divided into the study group and control group using the random number table method. The patients received usual care in the control group, and received high-quality nursing based on hope theory in the study group. Then, the degree of pain, fatigue, anxiety and depression were evaluated using visual analogue scale (VAS), chronic pain self-efficacy scale (CPSS), cancer fatigue scale (RPFS), self-rating anxiety scale (SAS) and self-rating depression scale (SDS). The hope level and coping style were assessed using Herth hope scale (HHI) and summary coping style questionnaire (SCSQ). The quality of life was assessed using Medical Outcomes Study item short from health survey (SF-36). Moreover, nursing satisfaction was compared using homemade questionnaire. Results: The results showed that VAS score, RPFS score, SDS score and passive coping score of SCSQ questionnaire in the study group were lower than those in the control group (p &lt; 0.05). CPSS score, HHI score, positive coping score of SCSQ questionnaire, nursing satisfaction and SF-36 scores in all dimensions in the study group were higher than those in the control group (p &lt; 0.05). Discussion: The high-quality nursing model based on hope theory could ameliorate patients’ pain and fatigue, enhance their self-efficacy, guide patients to face problems positively, improve their life quality and hope level. Conclusion: It has higher nursing satisfaction in endometrial cancer.

Psychological Factors Associated with Functional Disability in Patients with Hip and Knee Osteoarthritis

Several studies have shown an association between psychosocial variables and functional capacity in chronic pain processes such as osteoarthritis. The aim of this study was to test a structural equations model that shows the predictive weight of certain variables such as catastrophizing, self-efficacy and kinesiophobia on functional pain and WOMAC subscales scores of pain and physical function of older patients diagnosed with hip and knee osteoarthritis. We also assessed the specific weight of age in terms of the factors. The study was conducted on a sample of 170 patients (142 women and 28 men mean age, 74.44 years range, 50–96 years). The main variables evaluated were WOMAC subscales scores of pain and physical function, self-efficacy, catastrophizing and kinesiophobia. To assess these variables, we used the Spanish validated version of the Western Ontario and McMaster Universities questionnaire, the Chronic Pain Self-Efficacy Scale, the Pain Catastrophizing Scale and the Tampa Scale for Kinesiophobia, respectively. We tested a structural equations model (IBM SPSS Amos version 22). The results showed the predominant predictive weight (both direct and indirect) of catastrophizing while simultaneously ruling out the relevance of age as a predictor of WOMAC subscales scores of pain and physical function. This study provides data of interest on the explanatory mechanisms that underlie the direct and inverse relationships between the studied psychological variables.

Pain Neuroscience Education Plus Usual Care Is More Effective than Usual Care Alone to Improve Self-Efficacy Beliefs in People with Chronic Musculoskeletal Pain: A Non-Randomized Controlled Trial

Self-efficacy beliefs are associated with less physical impairment and pain intensity in people with chronic pain. Interventions that build self-efficacy beliefs may foster behavioral changes among this population. A non-randomized trial has been carried out to evaluate the effectiveness of pain neuroscience education (PNE) plus usual care in modifying self-efficacy beliefs, pain intensity, pain interference and analgesics consumption in people with chronic musculoskeletal pain. Participants were allocated to an experimental (PNE plus usual care, n = 49) and a control (usual care alone, n = 51) group. The primary outcome was self-efficacy beliefs (Chronic Pain Self-Efficacy Scale), and the secondary outcomes were pain intensity, pain interference (Graded Chronic Pain Scale) and analgesics consumption. The participant’s pain knowledge (revised Neurophysiology of Pain Questionnaire) after PNE intervention was also assessed to analyze its influence on every outcome measure. All the outcome measures were assessed at the baseline and at four-week and four-month follow-ups. PNE plus usual care was more effective than usual care alone to increase self-efficacy beliefs and decrease pain intensity and pain interference at all follow-up points. No differences between groups were found in terms of analgesics consumption. Knowledge of pain neurophysiology did not modify the effects of PNE plus usual care in any of the outcome measures. These results should be taken with caution because of the non-randomized nature of this design, the limited follow-ups and the uncertainty of the presence of clinical changes in self-efficacy for participants. Larger, methodological sound trials are needed.

Self-efficacy in patients with chronic musculoskeletal conditions discharged from physical therapy service: A cross-sectional study.

This study aimed to investigate self-efficacy levels of patients after finishing rehabilitation for chronic musculoskeletal conditions and identify factors related to self-efficacy. Two hundred and eight patients aged >40 years with musculoskeletal disorders were included. Self-efficacy was assessed by the Chronic Pain Self-Efficacy Scale (CPSS), and regression analyses were used to test six predictors of self-efficacy: age, symptom duration, number of physical therapy sessions, postdischarge pain intensity, perceived clinical improvement, and cognitive reassurance. Self-efficacy was compared between patients who reported improvement and worsening of their clinical condition, and a cutoff value for self-efficacy was established using receiver operating characteristic curve analyses to distinguish patients with severe pain from those with mild to moderate pain. Better perceived clinical improvement (Beta = -0.37, p = 0.000), lower pain intensity (Beta = -0.33, p = 0.000), and a lower number of physical therapy sessions (Beta = -0.12, p = 0.027) were related to greater self-efficacy. No significant associations were observed between self-efficacy and age, symptom duration, and cognitive reassurance. The patients who reported improvement had greater self-efficacy (204.76 ± 52.80) than those who reported worsening of their clinical condition (145.45 ± 44.18; p = 0.000). A CPSS score of 172 points (sensitivity of 0.77; specificity of 0.72) may indicate low self-efficacy. A higher perception of self-efficacy after discharge from physiotherapy is associated with better perceived clinical improvement, lower pain intensity, and a lower number of physical therapy sessions. Therefore, interventions to support patients' exercise-based rehabilitation should include self-efficacy, which may affect the prognosis of patients with chronic conditions.

Pain-related Self-efficacy Among People With Back Pain: A Systematic Review of Assessment Tools.

Before an intervention can be implemented to improve pain-related self-efficacy, assessment is required. The aim of the present study was to provide a systematic review on which self-efficacy scales are being used among patients with back pain and to evaluate their psychometric properties. A systematic search was executed in January 2019 and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2009 checklist served as a guide for conducting the study. Electronic databases included Cinahl, Medline, PubMed, PsycINFO, PSYNDEX, and SportDiscus. Publications in English or German language that focused on the adult patient population with back pain and which provided validation or reliability measures on pain-related self-efficacy were included. A total of 3512 records were identified resulting in 671 documents after duplicates were removed. A total of 233 studies were screened full-text, and a total of 47 studies addressing 19 different measures of pain-related self-efficacy were included in the quality analysis. The most commonly used instruments were the Pain Self-Efficacy Questionnaire and the Chronic Pain Self-Efficacy Scale. All studies reported internal consistency, but many studies lacked other aspects of reliability and validity. Further research should focus on assessing validity and interpretability of these questionnaires, especially in pain-related target groups. Researchers should select questionnaires that are most appropriate for their study aims and the back pain population and contribute to further validation of these scales to best predict future behavior and develop intervention programs. This systematic review aids selection of pain-related assessment tools in back pain both in research and practice.

Evaluation of self-efficacy determinants in community-dwelling older adults with chronic musculoskeletal pain

INTRODUCTION: Self-efficacy is defined as the strength of a person’s convictions in being able to perform a given activity and obtain the expected result. It may act as a potent mediator between chronic musculoskeletal pain and how older adults cope with their disabilities. OBJECTIVE: To evaluate the determinants of self-efficacy beliefs and fear of physical exercise in community-dwelling older adults with chronic musculoskeletal pain. METHODS: This cross-sectional study recruited older adults with chronic musculoskeletal pain. Only individuals living in an urban area in southern Brazil and who reported pain for more than 3 months were included. A convenience sample was selected in a nonprobabilistic fashion. The study variables consisted of sociodemographic data; pain based on the Brief Pain Inventory and the Leeds Assessment of Neuropathic Symptoms and Signs for Patients with Chronic Pain; and self-efficacy based on the Chronic Pain Self-Efficacy Scale. Also, simple questions were created for physical exercise beliefs. For statistical analysis, absolute and relative frequency, χ2 test, and Mann-Whitney U test were used as appropriate. RESULTS: The sample consisted of 193 older adults, mostly women with low level of education. Self-efficacy was best rated by older adults living alone and by those who were classified as exclusively nociceptive pain. CONCLUSION: Despite having chronic pain, older adults with higher self-efficacy feel confident in performing their tasks and have greater ability to cope with changes related to aging and to engage in self-care.

Determinants of quality of life among family caregivers of adult cancer patients in a resource-limited setting.

In resource-limited settings, family caregivers (FCGs) of adult cancer patients (ACPs) function in a context marred by high patient symptom burden, limited cancer care services and support and high caregiving burden. Despite this predicament, little is known about the quality of life (QoL) of FCGs in these settings. The study aimed to explore the determinants of QoL among FCGs of ACPs in Uganda. A cross-sectional design was used to collect data from 284 FCGs of ACPs. The study questionnaire was composed of the Katz Index, Family Pain Questionnaire, modified Chronic Pain Self-efficacy Scale and the Caregiver Quality of Life-Index-Cancer. The mean age of FCGs was 36 ± 13.8years. Most ACPs had stage 3 or 4 cancer (56%), severe pain (66.2%), reported moderate pain relief (51.1%) and were on chemotherapy (60.9%). The overall QoL of FCGs (70.2 ± 20.3) was moderate and 46.8% had low QoL. Most FCGs had high positive adaptation or financial concerns (55.3%) and low QoL in terms of burden (50.7%), disruptiveness (53.5%) and support (56.7%). The main determinants of overall QoL were FCGs' knowledge and self-eficacy for cancer pain management. The determinants of burden, disruptiveness, support and positive adaptations and financial concerns are reported. The key determinants of the QoL of FCGs were knowledge and self-efficacy for cancer pain management. In Uganda and similar settings, interventions to build FCGs capacity in cancer-related pain and other symptom management may help to enhance the QoL of FCGs and the ACPs.

Developing a Short Multidimensional Measure of Pain Self-efficacy: The Chronic Pain Self-efficacy Scale-Short Form.

The 22-item Chronic Pain Self-efficacy Scale (CPSS) measures three domains of pain self-efficacy: pain management, physical functioning, and coping with symptoms. This study aims to develop a short form (CPSS-SF) that retains the multidimensional structure of the instrument. Six hundred sixty-four community-dwelling Chinese older adults aged 60-95 years with chronic pain completed a survey. Confirmatory factor analysis (CFA) was conducted on the 22-item CPSS. Regression analyses were performed to examine the items' correlations with criterion variables. After CPSS-SF items were selected, the performance of CPSS-SF subscales in terms of accounting for pain-related outcomes was compared with the full version. CFA supported a modified 3-factor model of the CPSS. On the basis of factor loadings on the 3 dimensions and the items' correlations with pain intensity and pain disability, 11 items were selected for the CPSS-SF, which correlated at .97 with the full version. Regression analyses showed that the associations of the CPSS-SF subscales with pain intensity, pain disability, depressive symptoms, instrumental activities of daily living, and physical and mental health-related quality of life, were indistinguishable from their full-version counterparts. The CPSS-SF is a valid instrument that can be used in lieu of the full scale. Its availability will facilitate the assessment of pain self-efficacy in research and clinical settings due to its brevity but strong psychometric properties. However, the current evidence is limited to Chinese older adults; more research is needed to ascertain its validity in other age and cultural groups.

Telephone Follow-up Design and Practice for Advanced Cancer Pain Patients.

To describe the design of a telephone follow-up protocol and to evaluate the feasibility of this protocol for advanced cancer pain patients. A series of nine telephone follow-up calls was implemented with 40 advanced cancer pain patients within 3months after their discharge from the Department of Chemotherapy. Cancer pain information and the pain-related knowledge of the patients were collected by nurses using pain follow-up information sheets and the Patient Pain Questionnaire (PPQ); pain self-efficacy and the quality of life were reported by patients using the Chronic Pain Self-Efficacy Scale (CPSS) Chinese version and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC-QLQ-C30) Chinese version. The average score assessed by advanced cancer pain patients of the need for pain care from nurses was 24.28 (SD = 4.90). Twenty-one and eight patients completed all nine telephone follow-up calls and seven self-reported questionnaires, respectively. The pain intensity of patients at the time of follow-up was mild, but there had been breakthrough pain in the previous week. All patients were satisfied with the nurses' pain follow-up practices. There was a highly positive correlation between the time of follow-up and the patients' pain-related knowledge scores (r = 0.963**, p < 0.01). Patients' pain self-efficacy scores and quality of life scores varied across different dimensions. The baseline pain self-efficacy subscales were associated with all dimensions of quality of life (p < 0.05 or p < 0.01). Telephone follow-up can be an effective method of transitional care. For advanced cancer pain patients, it is still necessary to further explore the cost effectiveness of this method, including the appropriate follow-up duration, endpoints, and outcome measures based on government requirements and policies.

How Does Self-Efficacy Influence Pain Perception, Postural Stability and Range of Motion in Individuals with Chronic Low Back Pain?

Background: Low back pain (LBP) is the most prevalent musculoskeletal problem among adults. Individuals with chronic LBP (CLBP) can present a psychological disorder and a lack of pain self-efficacy. Objectives: The objective of this study was to compare the process of repetition-induced summation of activity-related pain, the lumbar range of motion, and the postural stability of patients with non-specific LBP (NSLBP) based on their level of self-efficacy. Study Design: This research used a descriptive, cross-sectional study design. Methods: This research included 60 patients with NSCLBP. Patients were classified as having “high” or “low” self-efficacy based on a median split of scores on the Chronic Pain Self-Efficacy Scale. All patients received a sociodemographic questionnaire, a psychological self-reported measures (Tampa scale of Kinesiophobia; Pain Catastrophizing Scale; Rumination subscale, Magnification subscale; Helplessness subscale; Roland-Morris Disability Questionnaire; FearAvoidance Belief Questionnaire; Physical Activity subscale; Work subscale); and completed the Temporal Summation Lifting Task, Lumbar Range of Motion, and Multi-Directional Functional Reach Test (MDFRT). Results: The results indicated that the low self-efficacy group had a shorter lumbar range of motion and lower postural stability, in addition to greater pain intensity in the temporal summation lifting task, compared with the high self-efficacy group. The analysis showed that the strongest correlation for the high self-efficacy was between fear of movement and the temporal summation lifting task, and greater scores at the psychological questionnaires, compared with the high selfefficacy group (r = 0.711; P &lt; 0.01). The strongest correlations found for the low self-efficacy group, showed a positive relationship between pain catastrophizing and the temporal summation lifting task (r = 0.765; P &lt; 0.01), and a strong negative association between pain catastrophizing for the magnification subscale and lumbar range of motion (r = -0.759; P &lt; 0.01). Limitations: The results of this study should be interpreted with caution because of its crosssectional design, and therefore causal relationships cannot be established. A significant limitation of the study is that patients’ physical activity levels were not assessed, which could have influenced their ability to perform motor tasks at the perceived difficulty and fear level. Conclusions: The high self-efficacy group had less pain in the temporal summation lifting task, a greater range of motion, and a greater functional range, in addition to a lower influence of psychological factors. Key words: Low back pain, chronic pain, self-efficacy, temporal summation, range of motion, postural stability, fear of movement, pain catastrophizing, low back disability

Family caregivers for adult cancer patients: knowledge and self-efficacy for pain management in a resource-limited setting.

To assess the FCGs' knowledge and SE levels for pain management among ACPs while at home in a resource-limited setting. Using a questionnaire that comprised a Family Pain Questionnaire and Chronic Pain Self-efficacy Scale, data were collected from 284 FCGs of ACPs receiving care from two cancer care centres. The FCGs had moderate knowledge (mean = 41.70 ± 14.1) and SE (mean = 795.95 ± 301.3) levels for pain management at home for ACPs. Majority of the FCGs had low knowledge (52.1%), but expressed higher SE (52.5%). Poor self-rated health among FCGs was significantly associated with low knowledge levels (OR = 1.75; 95% CI 1.024-2.978, p = 0.041). SE was significantly associated with perceiving a low impact of caregiving on health (OR = 1.55; 95% CI 1.074-2.239, p = 0.019), hours of caregiving per week (OR = 0.52; 95% CI 0.315-0.854; p = 0.01) and receiving organisational support (OR = 0.388; 95% CI 0.222-0.679; p = 0.001). The results show a need for deliberate interventions to enhance FCG knowledge and SE for pain management at home as one of the ways of improving cancer pain management in resource-limited settings.

Relationship of Dynamic Balance Impairment with Pain-Related and Psychosocial Measures in Primary Care Patients with Chronic Greater Trochanteric Pain Syndrome

Subjects with greater trochanteric pain syndrome (GTPS) show an altered physical function while performing static and dynamic tasks. Pain and psychosocial factors are also variables that influence the outcomes of these patients. Thus, the aim of this study was to evaluate the relationship between dynamic balance, pain-related measures, and psychosocial measures in subjects with chronic GTPS. Descriptive cross-sectional study. Primary health care center. Fifty-one subjects with greater trochanteric pain syndrome were recruited. Dynamic balance was evaluated using the Y-Balance Test (YBT), and a self-reported test battery was used to assess the following aspects: pain catastrophizing (Pain Catastrophizing Scale [PCS]), kinesiophobia (Tampa Scale of Kinesiophobia [TSK-11]), pain intensity (visual analog scale [VAS]), disability (Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC]), and self-efficacy (Chronic Pain Self-Efficacy Scale [CPSS]). Correlation analysis showed that YBT was negatively associated with the VAS average, the helplessness subscale of the PCS, and the pain and function subscales and total score of the WOMAC. YBT was positively associated with the pain subscale of the CPSS. The scores of the YBT forward movement were predicted by the VAS average (38.1% of variance) in addition to the WOMAC total score (34.2% of variance) and TSK-11 total score (43.8% of variance). The findings of this study suggest that kinesiophobia, pain, and physical function are related to dynamic balance in subjects with GTPS. Thus, when diagnosing and planning the treatment of patients with GTPS, psychosocial and physical function factors should be taken into account, in addition to pain management.

The effectiveness of attachment on global pain in chronic pain sufferers: the mediating effect of pain self-efficacy

Objective To identify global pain and attachment in chronic pain sufferers, and explore the mediating effect of pain self-efficacy. Methods There were 193 patients recruited from Pain Department in West China Hospital of Sichuan University between February 2017 and June 2017. The Global Pain Scale, Experiences in Close Relationships Questionnaire-Revised and Chronic Pain Self-efficacy Scale were used to collect data. Results The score of global pain, attachment avoidance and attachment anxiety were (79.55±15.82), (2.98±0.81) and (3.22±0.89) points respectively. 52.8%(102/193) participants were secure attachment. Mediating effect analyses revealed that self-efficacy exerted a partial mediating effect between global pain and attachment, with the mediating effect of 33.3% in total effect. Conclusions Health professionals should improve the self-efficacy in the management of chronic pain, especially in those with strong relationship needs, promote the positive pain adjustment, and improve the quality of life. Key words: Chronic pain; Attachment; Global pain; Self-efficacy

Comparison of pain, disorder, back performance, and psychological factors in patients with low back pain and radicular pain.

[Purpose] This study investigated the relationship between pain intensity, lumber disability, and psychological factors in patients with low back pain. [Subjects and Methods] A total of 166 outpatients (116 female, 50 male) with chronic low back pain presenting for physical therapy participated in this study. Patients were divided into two groups: those with low back pain alone and those with both low back pain and radicular pain. Pain intensity and lumbar disability were measured using a visual analogue scale and the Roland-Morris Disability Questionnaire. Psychological factors, such as self-efficiency, fear avoidance, and depression were measured using the Chronic Pain Self-efficacy Scale, Fear-Avoidance Beliefs Questionnaire, and Beck Depression Index, respectively. [Results] Patients with low back pain with radicular pain had greater pain and lumber disability and lower psychological factors compared with patients with chronic low back pain alone. [Conclusion] Our findings indicate the presence of low back pain with radicular pain is more related to pain, LBP disability index, Back performance, Self-efficiency (Pain, Function, Symptom), Fear-avoidance (body, work) and depression factors than low back pain. Considering the relationships between in pain, LBP disability index, Back performance, Self-efficiency (Pain, Function, Symptom), Fear-avoidance (body, work) and depression factors in patients with low back pain, therapeutic intervention for not only pain and dysfunction, but also psychological factors is needed.

The discordance between subjectively and objectively measured physical function in women with fibromyalgia: association with catastrophizing and self-efficacy cognitions. The al-Ándalus project

Purpose: People with fibromyalgia experience a disagreement between patient-reported (i.e., subjective) and performance-based (i.e., objective) status. This study aimed to (i) corroborate the discordance between subjectively and objectively measured physical function and (ii) examine whether catastrophizing (worrying, pain magnifying, and helpless cognitions) and self-efficacy (believing capable to manage pain) are independently associated with this discordance.Methods: This population-based cross-sectional study included 405 women with fibromyalgia and 193 age-matched female controls. Participants completed the Pain Catastrophizing Scale, Chronic Pain Self-efficacy Scale, and physical functioning subscales of the Revised Fibromyalgia Impact Questionnaire and Short Form-36 (SF-36) health survey. Objective physical function was measured with the Senior Fitness Test battery. Subjective and objective physical functions were expressed as deviation from the general population in standard deviation (SD) units using means and SD of the control group.Results: In fibromyalgia, subjective physical function was worse than objective physical function (p < 0.001). Higher catastrophizing was consistently associated with greater discordance between subjective and objective physical function, while self-efficacy was only significantly associated with this discordance when subjective physical function was assessed by means of the SF-36.Conclusions: Subjective physical function is more impaired than objective physical function in fibromyalgia, yet both are markedly impaired. Catastrophizing cognitions are associated with this discordance. In particular, high catastrophizing may promote a feeling of reduced ability to do meaningful activities of daily living (i.e., restrictions) that people with fibromyalgia are actually able to. Therefore, catastrophizing should be assessed and potentially targeted when focusing on improving physical function in fibromyalgia.Implications for rehabilitationRehabilitation should focus on physical exercise programs to help women with fibromyalgia to improve their reduced physical function.In rehabilitation settings, physical function of people with fibromyalgia should be evaluated by both subjective and objective assessments to fully understand physical functioning and to test the existence of discordance between both assessments.In case of a large discordance between subjective and objective physical function, a physical exercise program might be better complemented with cognitive management techniques to reduce catastrophizing and subjective physical dysfunction.When people with fibromyalgia experience high levels of catastrophizing, subjective assessments seem to be poor indicators of physical function.
