Emotional Distress Correlates Among Patients With Chronic Nonspecific Low Back Pain: A Hierarchical Linear Regression Analysis

Correlation between sagittal parameters and disability of patients with nonspecific chronic low back pain: a cross-sectional study of 435 subjects

BACKGROUND CONTEXT

Sagittal parameters are significantly correlated with health-related quality of life (HRQoL) in adult spinal deformity patients. Their association with HRQoL in patients with nonspecific chronic low back pain (NSCLBP) is unclear.

PURPOSE

To analyze the correlation between sagittal parameters and disability in NSCLBP patients.

DESIGN

A cross-sectional study.

PATIENT SAMPLE

Subjects included 435 patients with NSCLBP divided into low disability and high disability groups.

OUTCOME MEASURES

Function was measured using the Oswestry Disability Index (ODI). Pain intensity was measured using the Numeric Rating Scale (NRS) and HRQoL was measured using 36-item Short Form Health Survey (SF-36).

METHODS

Sagittal parameters, demographic data, ODI, SF-36 eight-dimensional scores and NRS scores of patients with NSCLBP were collected. Taking ODI=20 as the cut-off value, patients were divided into low disability group (ODI≤20) and high disability group (ODI>20), and ODI were converted to Ranked ODI (RODI) accordingly. Univariate analysis of the correlation among age, gender, body mass index (BMI), sagittal parameters, RODI, SF-36 eight-dimensional scores, NRS scores were then conducted. The variables related to RODI were analyzed by logistic regression to discover their independent influence on RODI. p<.05 was considered to indicate statistical significance.

RESULTS

A total of 435 patients with NSCLBP were included. Univariate correlation analysis showed that the correlation coefficients between age, sacral slope-pelvic tilt (SS-PT), spinosacral angle (SSA) and RODI were (r=0.126, p<.01), (r=-0.115, p<.05), (r=-0.116, p<.05), respectively. The logistic regression analysis indicated that the regression coefficients of age and SSA were 0.030 (p=.001), -0.044 (p=.002), respectively, and the odds ratio and 95% confidence interval (CI) were 1.031 (1.012, 1.050), 0.957 (0.930, 0.985).

CONCLUSIONS

Age and SSA are independent factors for disability of NSCLBP. SSA can comprehensively reflect the sagittal balance of the spine of patients with NSCLBP. Decreased SSA represents poor sagittal balance, which will increase the disability of NSCLBP.

Pain Catastrophizing Dimensions Mediate the Relationship between Chronic Pain Severity and Depression

BACKGROUND

Although past studies have found significant positive correlations of both pain severity and overall pain catastrophizing (PC) levels with depression in chronic pain samples, less is known about the extent to which specific PC dimensions (i.e., helplessness, magnification, rumination) explain links between pain severity and depression.

AIM

This study assessed the relative importance of PC dimensions as mediators of relations between chronic pain severity and depression.

DESIGN

A cross sectional study design was employed.

METHOD

Mainland Chinese adults with chronic pain (n = 983) completed validated questionnaire measures of PC, depression, and chronic pain severity within a cross-sectional research design.

RESULTS

Analyses indicated helplessness mediated the association between pain severity and depression while magnification partially mediated the association of helplessness with depression. Conversely, rumination did not make a significant contribution in the mediation model.

CONCLUSIONS

The helplessness dimension of PC, in particular, may help to explain why people with more severe chronic pain are prone to co-occurring depression.

The Interconnection Between Social Support and Emotional Distress Among Individuals with Chronic Pain: A Narrative Review

Chronic pain is a public health concern affecting over 100 million U.S. adults. Because chronic pain is multifactorial, it requires a biopsychosocial approach to understand how biological, psychological, and social factors contribute to both the development and maintenance of pain. On average, individuals with chronic pain report higher levels of emotional distress compared to pain-free individuals. Research has demonstrated that social support is associated with better pain outcomes and less emotional distress. It has been proposed that social support may improve pain outcomes by reducing the influence of stressors. However, the majority of research exploring the relationships between social support and pain-related outcomes has focused on the direct relationship between these variables, largely overlooking the process by which social support has a positive influence on pain. This narrative review synthesizes research on how chronic pain, emotional distress, and social support are highly interconnected, yet research investigating chronic pain and emotional distress within a social context is limited. We then highlight disparities in chronic pain, such that the burden of chronic pain is unequal between demographic groups. Next, we discuss existing evidence for the use of group-based interventions to address pain-related outcomes. Lastly, we summarize limitations of prior research studies and highlight gaps in the current literature. Overall, longitudinal research comprehensively investigating the distinct nuances in the measurement of social support and how these nuances relate to emotional distress and pain outcomes is needed and may provide insight into the unique needs of individuals or subgroups. Further, demographically diverse randomized controlled trials are needed to identify the process by which group-based interventions improve pain outcomes and whether these interventions are more effective for particular groups in order to personalize treatment approaches and address inequities in pain care.

Investigation and analysis of training injury and its psychological effects on firefighters in Beijing A cross-sectional study

Firefighters' high-intensity training often leads to injuries in the musculoskeletal system. Studies have found that these injuries in the musculoskeletal system may contribute to poor psychological issues. At the same time, low psychological well-being increases the risk of injuries, illness, and mortality. According to research reports, firefighters generally have a good psychological state. So this study aims to survey and analyze the training-related injuries and psychological states of firefighting and rescue personnel in Beijing. This cross-sectional study employed a questionnaire survey to gather data from a total of 214 firefighters in a certain city. The participants were required to complete a questionnaire about musculoskeletal injuries and psychological status, and then these data were statistically analyzed. The incidence of training-related injuries is relatively high among firefighting and rescue teams, with the highest proportions observed in the lower back, knees, and ankles. Overweight and obese firefighters are more prone to ankle injuries. In the group with injuries, the subjective well-being index is lower compared to the group without injuries. Firefighters experiencing moderate to severe pain due to injuries exhibit lower subjective well-being indices compared to those with mild pain. Psychological resilience and the impact of pain on training and sleep can predict the subjective well-being index of firefighters. It is recommended that firefighting and rescue teams enhance preventive measures for musculoskeletal injuries during training to elevate the subjective well-being of firefighters.

Pregnancy-related low back/pelvic girdle pain: Prevalence, severity, and risk factors in Zhengzhou, China

BACKGROUND

Pregnancy-related low back pain (LBP) and pelvic girdle pain (PGP) significantly affect the quality of life of pregnant women. Understanding their severity and risk factors may help prevent and alleviate such pain and their resulting dysfunction.

OBJECTIVE

This study investigated the prevalence, severity, and biopsychosocial risk factors of pregnancy-related LBP and PGP in Zhengzhou, China.

METHODS

The Numeric Pain Rating Scale (NPRS), Chinese version of the Roland-Morris Disability Questionnaire (RMDQ), and other questionnaires were self-administered by 1020 pregnant women undergoing treatment at a tertiary hospital between July and December 2019. Binary logistic regression was used to identify factors associated with pregnancy-related LBP and/or PGP.

RESULTS

The prevalence of LBP and/or PGP during pregnancy was 63.0%, and most participants (80.4%) had both. The mean NPRS and RMDQ disability scores were 2.44 ± 2.10 and 6.66 ± 4.65, respectively. A higher gestational body mass index, LBP and/or PGP during menstruation, history of pregnancy-related LBP and/or PGP, and constant pressure were significantly associated with pregnancy-related LBP and/or PGP. Subjective support was a protective factor against LBP and/or PGP.

CONCLUSION

The prevalence of LBP and/or PGP was high. The risk factors should be included in routine prenatal care to identify patients at risk of LBP and/or PGP.

The Role of Adaptive Goal Processes in Mental Wellbeing in Chronic Pain

Chronic pain, experienced as pain persisting for three months or longer, is associated with risk of poor mental health and disability. Research has implicated adaptive goal processes as important to mental wellbeing in a range of populations. However, research has rarely assessed these mechanisms in relation to pain characteristics and mental wellbeing in chronic pain populations. This study aimed to examine the potentially mediating roles of goal flexibility and goal tenacity in the relationships between pain intensity and pain interference and mental wellbeing among individuals with chronic pain. Community members who self-identified as experiencing non-cancer chronic pain (N = 315) completed an online self-report survey on goal tenacity, goal flexibility, mental wellbeing, pain intensity, and pain interference. Unexpectedly, pain intensity was not significantly related to mental wellbeing, when controlling for pain interference. However, pain interference was directly and significantly associated with mental wellbeing. Both goal flexibility and goal tenacity mediated the relationship between pain interference and mental wellbeing, whilst controlling for pain intensity. The results provide support for the protective role of adaptive goal processes in mental wellbeing in those with chronic pain and highlight the importance of pain interference in relation to mental wellbeing.

Effectiveness of smartphone apps for the self-management of low back pain in adults: a systematic review

PURPOSE

To explore the effectiveness of smartphone apps for the self-management of low back pain in adults.

METHODS

Prospectively registered systematic review of randomised controlled trials (2008-) published in English. Studies investigating smartphone apps for the self-management of low back pain (adults ≥18 years), including ≥1 NICE low back pain and sciatica clinical guideline-recommended component and functioning without health professional input were included. Outcomes were pain, function, quality of life and adherence.

RESULTS

Six studies were included (n = 2100 participants). All comparator groups incorporated some form of management (n = 3 physiotherapy, n = 2 GPs, n = 1 not specified). Three studies reported a significant decrease in pain intensity in the intervention group compared with the control. One study reported no significant difference between groups in pain self-efficacy. One study reported a significant reduction in disability (function) in the intervention group compared with the control. Two studies reported no between-group differences in quality of life. One study reported no correlation between adherence (app use) and change in pain intensity and one study reported that app use mediated the effect of teleconsultations on pain improvements.

CONCLUSIONS

Inconclusive evidence exists for the use of smartphone applications for the self-management of low back pain. Further research is needed.Implications for RehabilitationSmartphone apps have the potential to improve outcomes for people with LBP aligned with current self-management guidelines.There is a paucity of literature exploring smartphone apps for LBP self-management and current evidence is inconclusive for smartphone app use without supported care.Commercially available smartphone apps are not well regulated for content or alignment with evidence-based guidelines and recommendations.Further evaluation of commercially available apps is required to guide and instil confidence in consumers and health professionals that consumer-accessible apps may lead to improved outcomes.

Availability, content and quality of commercially available smartphone applications for the self-management of low back pain: a systematic assessment

PURPOSE

Explore smartphone apps that may be recommended by clinicians for the self-management of low back pain.

METHODS

Prospectively registered systematic assessment of self-contained apps for self-management of low back pain on the Google Play and Apple App stores (Oceania), including ≥1 NICE low back pain and sciatica clinical guideline-recommended component and functioning without health professional input. Outcomes were quality (Mobile App Rating Scale; MARS), and self-management (Self-Management Support Checklist; SMS-14) and behaviour change potential (App Behaviour Change Scale; ABACUS).

RESULTS

25 apps were included. The average quality of included apps was acceptable (Mean MARS score of 3.9 out of a maximum possible 5). The self-management support and behaviour change potential of included apps appeared low (mean SMS-14 score was 3.4/14; mean ABACUS score was 5.4/21). The apps showed no significant correlation between app consumer ratings and MARS scores. App quality was significantly correlated with app price (p = 0.049) but not consumer ratings, however, these findings were based on a small number of studies and the overall model was not significant.

CONCLUSIONS

Smartphone apps for the self-management of low back pain are of average to good quality, with questionable potential for self-management and behaviour change. Clinicians should consider that few apps were designed to specifically incorporate self-management support and behaviour change potential when recommending apps to clients. Further development in these areas of app design would be of benefit.Implications for RehabilitationSmartphone apps have the potential to improve LBP self-management outcomes, however, apps are not well regulated and the quality of information and advice provided is often low quality.The findings from this systematic assessment indicate that LBP self-management apps have limited self-management support and behaviour change potential features.Recommendation of current smartphone apps for LBP should take into consideration that although apps are of acceptable quality they are not specifically designed with self-management support and behaviour change principles.App quality does not appear to be associated with consumer ratings, however, there may be a positive association between app price and quality which requires further investigation.

The Mediating Effects of Social Support on the Relationship between Uncertainty and Quality of Life among Patients with Chronic Low Back Pain: A Cross-Sectional Survey

Background: This study aimed to investigate the mediating effects of social support on the relationship between uncertainty and quality of life (QOL) in patients with chronic low back pain (LBP). Methods: From 1 July 2019 to 25 March 2020, data were collected using a structured questionnaire from inpatients and outpatients > 20 years of age with chronic LBP lasting > 3 months. Inpatients included patients waiting for surgery and those recovering after surgery. The exclusion criteria were cancer and other serious pathological diseases. The relationships between uncertainty, social support, and QOL were analyzed using Pearson’s correlation coefficients. Results: Uncertainty, the independent variable, exerted a significant effect on social support, the mediator (B = 0.33, p < 0.001). In addition, both uncertainty (B = 0.37, p < 0.001) and social support (B = 0.45, p < 0.001) exerted statistically significant effects on QOL, the dependent variable. Conclusions: Disease-related uncertainty can reduce QOL in patients with chronic LBP, and this relationship is mediated by the level of social support. To develop strategies for strengthening social support from healthcare providers, family, and friends, future studies should examine the experiences of patients with chronic LBP from various perspectives, including pain intensity and duration.

Microblog User Emotion Analysis Method Based on Improved Hierarchical Attention Mechanism and BiLSTM

The goal of Chinese fine-grained emotion analysis is to identify the target words corresponding to fine-grained elements from sentences and determine the corresponding emotional polarity for the target words. Aiming at the problem that the current Sina Microblog user emotion analysis methods have low accuracy and are difficult to effectively predict and manage, a Sina Microblog user emotion analysis method based on the Bidirectional Long Short-Term Memory algorithm (BiLSTM) and improved hierarchical attention mechanism is proposed. Firstly, an emotion analysis model is constructed based on text-level analysis and subjective and objective analysis, and the dimensionality curse problem of one-hot representation is solved by integrating the weighted word vector of TF-IDF. Then, by constructing a bidirectional long short-term memory neural network, the full acquisition of context information is realized, which increases the fine-grained elements of emotion analysis. Finally, by introducing an improved hierarchical attention mechanism, the network model can focus on different parts to achieve text classification and emotion analysis. Through simulation experiments, the proposed emotion analysis method and the other two methods are compared and analyzed under the condition of using the same database. The results show that the precision, recall, and F1 value of the method proposed in this paper are the best under 7 different emotion classifications, with the highest reaching 95.8%, 95.9%, and 96.1%, respectively, and the algorithm performance is better than the other two comparisons algorithm. It is proved that the proposed model has excellent performance.

An improved multi-objective imperialist competitive algorithm for surgical case scheduling problem with switching and preparation times

Surgical case scheduling is a key issue in the field of medician, which is a challenging work because of the difficulty in assigning resources to patients. This study regards the surgical case scheduling problem as a flexible job shop scheduling problem (FJSP). Considering the switching and preparation time of patients in different stage, an improved multi-objective imperialist competitive algorithm (IMOICA), which adopts the non-dominant sorting method, is proposed to optimize the whole scheduling. First, the social hierarchy strategy is developed to initialize the empire. Then, to enhance the global search ability of the algorithm, the concept of attraction and repulsion (AR) is introduced into the assimilation strategy. Moreover, to increase the diversity of the population, the revolution strategy is utilized. Finally, the variable neighborhood search (VNS) strategy is embedded to improve its exploitation capacity further. Experiments show that scheduling in advance saves time and cost, and IMOICA can solve the surgical case scheduling problem studied efficiently.

PREVALENCE OF LOW BACK PAIN AND EVALUATION OF RISK FACTORS IN HOSPITALIZED PATIENTS

ABSTRACT Objective To determine the prevalence of low back pain and to establish a correlation with risk factors for the development of low back pain in a teaching hospital in the East Zone of São Paulo. Method This is a cross-sectional, observational, analytical study, in which 90 patients from the teaching hospital wards were evaluated. Internationally validated instruments were used to assess clinical, epidemiological and behavioral aspects. Results The prevalence rate obtained was 57.73%, which is considered high compared to the rates in studies conducted outside of the hospital environment. There was predominance in the female sex, at 30.13% (SSD 5.32%). Sleep disturbances, measured indirectly through hours of sleep and the average pain score (p = 0.007), seem to act as a risk factor. The instruments for checking pain seem to be more effective when used together, with an association being observed between the Oswestry questionnaire (ODI) and the visual analog scale (VAS) for pain (p = 0.000). Conclusions There is a prevalence of low back pain among institutionalized individuals, especially those who are hospitalized, compared to rates observed outside the hospital environment. Level of evidence IV; Cross-sectional observational.
