Neck pain and anxiety do not always go together

Causal Relationship Between Psychosocial Factors and Neck Pain: A Two-Sample Mendelian Randomization Study

Purpose

Neck pain (NP) is a multifactorial disorder that leads to severe disability. This study aimed to investigate whether potential risk factors have a causal effect on NP at the genetic level using a two-sample Mendelian randomization (MR) analysis.

Methods

Summary-level data for potential risk factors, including distress, anxiety disorder, depression, mood, sleep disorder, loneliness, education, alcohol consumption, smoking, time spent using the computer, and physical activity, as well as NP, were obtained from multiple large-scale Genome-Wide Association Studies (GWAS). Instrumental variables (IVs) were extracted from these datasets. We employed inverse variance weighting (IVW), weighted median, and MR-Egger regression methods to assess causal effects. Heterogeneity was evaluated using MR-Egger regression and IVW, while horizontal pleiotropy was assessed using MR-PRESSO analysis and MR-Egger regression.

Results

The IVW results showed that major depressive disorder (OR = 1.51, 95% CI: 1.15, 1.98, p = 3.40×10-3) and experiencing mood swings (OR = 2.73, 95% CI: 1.57, 4.75, p = 3.86×10-4) were positively associated with NP and years of schooling (OR = 0.504, 95% CI: 0.410, 0.619, p = 6.55×10-11) was negatively associated with NP. Additionally, loneliness (OR = 16.0, 95% CI: 1.29-198, p = 0.0307) showed a suggestive association with NP. As for the other factors we did not find a clear causal relationship (All p-values > 0.05).

Conclusion

This two-sample MR study provides genetic evidence supporting a causal relationship between major depressive disorder, mood swings, and years of schooling with NP, while loneliness showed a potential association. These findings highlight the critical role of psychosocial factors, such as depression, mood swings, and education level, in the prevention and management of NP. Our results may offer new insights for clinicians to develop targeted intervention strategies aimed at reducing the incidence of NP.

Is there a relationship between psychological stress or anxiety and chronic nonspecific neck-arm pain in adults? A systematic review and meta-analysis

PURPOSE

To systematically review and analyze the research evidence linking stress or anxiety to chronic nonspecific neck-arm pain (NSNAP) in adults.

SUBJECTS AND METHODS

Data were obtained from Pubmed, Scopus, PsycInfo, Web of Science, Physiotherapy Evidence Database (PEDro) and The Cochrane library database from their inception to July 2015. Two authors independently conducted the searches, extracted data, and completed methodological quality assessments. The methodological quality of the cohort and case-control studies was evaluated using the Newcastle-Ottawa scale, whilst the quality of the Randomized Controlled Trial (RCT) was evaluated using the PEDro scale.

RESULTS

Twenty-eight studies involving 39,166 participants met the inclusion criteria. Four studies, including 5 pair-wise comparisons, were included in the meta-analysis: Three were cohort studies and 1 was a cross-sectional study. The meta-analysis outcome demonstrated a relationship between chronic NSNAP and psychological stress. The estimate odds ratio for all studies combined was 2.33 (95% CI, 1.04-5.18; p=0.039). A high heterogeneity of the findings appeared (Q=28.94, I²=86% p=0.00).

CONCLUSION

This study shows that there is a strong relationship between stress and chronic NSNAP. Despite this finding, we cannot support that stress is a risk factor for chronic NSNAP due to the low quality of the results according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE). It was not possible to make a quantitative analysis comparing the relationship between anxiety and chronic NSNAP. However, according to the qualitative analysis there is a strong relationship between anxiety and chronic NSNAP.

Value-based cognitive-behavioural therapy for the prevention of chronic whiplash associated disorders: protocol of a randomized controlled trial

BACKGROUND

Whiplash injury is the most common traffic-related injury affecting thousands of people every year. Conservative treatments have not proven effective in preventing persistent symptoms and disability after whiplash injury. Early established maladaptive pain behaviours within the first weeks after the injury may explain part of the transition from acute to chronic whiplash associated disorder (WAD). Hence, early targeting of psychological risk factors such as pain catastrophizing, fear-avoidance-beliefs, depression, and symptoms of posttraumatic stress disorder (PTSD) may be important in preventing the development of chronic WAD. Some evidence exists that targeting fear-avoidance beliefs and PTSD with exposure strategies and value-based actions may prevent development of persistent disability after whiplash injury. Yet, the results have to be tested in a randomized controlled trial (RCT). The primary objective of the present study is to test whether a specifically tailored value-based cognitive-behavioural therapy program (V-CBT) is able to prevent the development of persistent disability, pain, and psychological distress if delivered within the first three months after a whiplash injury.

METHODS/DESIGN

The current study is a two-armed randomized controlled study with a crossover design. Group A is scheduled for V-CBT within one week of randomization and group B with a delayed onset 3 months after randomization.

DISCUSSION

If the study detects significant effects of V-CBT as a preventive intervention, the study will provide new insights of preventive treatment for patients with WAD and thereby serve as an important step towards preventing the chronic condition.

Kinesiophobia in pre-operative patients with cervical discopathy and coexisting degenerative changes in relation to pain-related variables, psychological state and sports activity

BACKGROUND

No research group has ever investigated the level of kinesiophobia in a well defined group of preoperative patients treated due to cervical discopathy and degenerative spine disease, confirmed by X-ray and magnetic resonance imaging (MRI) examinations. We aimed to investigate the degree of kinesiophobia and the differences in pain-related and psychosocial characteristics between patients with high and low levels of kinesiophobia, in relation to factors commonly associated with neck pain.

MATERIAL/METHODS

Sixty-five consecutive patients with cervical discopathy and coexisting degenerative changes were assessed pre-surgically. The mean pain duration was 31.7 SD 34.0 months. Patients completed the Polish versions of the Tampa Scale for Kinesiophobia (TSK-PL) on 2 occasions, and the following once: Neck Disability Index (NDI-PL), State-Trait Anxiety Inventory (STAI-PL), Coping Strategies Questionnaire (CSQ-PL), and the Visual Analogue Scale (VAS-PL).

RESULTS

A high level of kinesiophobia was indicated in 81.5% and 87.7% of patients in first and second completion, respectively. Patients with high and low kinesiophobia differ in regards to the recreation section of NDI-PL (p=0.012), gender (p=0.043), and sports activity (p=0.024). Correlations were identified between TSK-PL and marital status (p=0.023) and sports activity (p=0.024).

CONCLUSIONS

Kinesiophobia levels are higher in patients with chronic cervical pain before surgical treatment. Fear of movement tends to be higher in women and among patients avoiding sports recreation before surgical treatment. Although sports activity and socio-demographic data are predictors of kinesiophobia, psychological, pain-related, and clinical data are not. These findings should be considered when planning rehabilitation after surgical treatment of cervical discopathy and coexisting degenerative changes.

Do male and female patients with chronic neck pain really have different health-related physical fitness, depression, anxiety and quality of life parameters?

AIM

The purpose of this study was to investigate whole body physical fitness parameters such as maximal aerobic capacity (VO₂ max), muscle strength, trunk flexibility, daily physical activity, pulmonary function, body composition, anxiety and depression, as well as other disease-related changes in patients with chronic neck pain (CNP), and to compare them with healthy controls.

METHOD

Eighty patients (40 male, 40 female) with CNP and 80 (40 male, 40 female) controls were included in this study. VO₂ max, handgrip and back-leg strengths, trunk flexibility, daily physical activity, pulmonary function test (PFT), body composition and pressure pain threshold (PPT) measurements were carried out. Neck disability index (NDI), Beck anxiety inventory (BAI), Beck depression inventory (BDI), Pittsburg sleep quality index (PSQI), and Short-Form health survey (SF-36) questionnaires were applied to all participants.

RESULTS

Handgrip and back-leg strengths and suboccipital and paraspinal-C7 PPTs and health-related quality of life (HRQoL) were lower, and PSQI, BAI and BDI were higher, in female patients with CNP, compared to healthy controls; whereas, VO₂ max and HRQoL were lower, and body fat percantage and PSQI were higher, in male patients with CNP, compared to healthy controls. Trunk flexibility and PFT values were not significantly different between the patients and the controls in both genders.

CONCLUSION

We suggest that, on the basis of gender, consideration of not only the neck region but also whole body physical fitness, anxiety and depression parameters in patients with CNP might be helpful to the development of more benefical strategies for illness management.
