The association between psychosocial factors and mental health symptoms in cervical spine pain with or without radiculopathy on health outcomes: a systematic review

BACKGROUND

Neck pain, with or without radiculopathy, can have significant negative effects on physical and mental wellbeing. Mental health symptoms are known to worsen prognosis across a range of musculoskeletal conditions. Understanding the association between mental health symptoms and health outcomes in this population has not been established. Our aim was to systematically review the association between psychosocial factors and/or mental health symptoms on health outcomes in adults with neck pain, with or without radiculopathy.

METHODS

A systematic review of published and unpublished literature databases was completed. Studies reporting mental health symptoms and health outcomes in adults with neck pain with or without radiculopathy were included. Due to significant clinical heterogeneity, a narrative synthesis was completed. Each outcome was assessed using GRADE.

RESULTS

Twenty-three studies were included (N = 21,968 participants). Sixteen studies assessed neck pain only (N = 17,604 participants); seven studies assessed neck pain with radiculopathy (N = 4,364 participants). Depressive symptoms were associated with poorer health outcomes in people with neck pain and neck pain with radiculopathy. These findings were from seven low-quality studies, and an additional six studies reported no association. Low-quality evidence reported that distress and anxiety symptoms were associated with poorer health outcomes in people with neck pain and radiculopathy and very low-quality evidence showed this in people with neck pain only. Stress and higher job strain were negatively associated with poorer health outcomes measured by the presence of pain in two studies of very low quality.

CONCLUSIONS

Across a small number of highly heterogenous, low quality studies mental health symptoms are negatively associated with health outcomes in people with neck pain with radiculopathy and neck pain without radiculopathy. Clinicians should continue to utilise robust clinical reasoning when assessing the complex factors impacting a person's presentation with neck pain with or without radiculopathy.

Association of psychological factors with limb disability in patients with cervical radiculopathy: comparison with carpal tunnel syndrome

Background

Regarding musculoskeletal conditions, patient’s psychological distress, are shown to be associated with higher disability. Cervical radiculopathy (CR) and carpal tunnel syndrome (CTS), are two conditions caused by entrapment of cervical nerve roots and carpal median nerve, respectively. This study aims to investigate the association of psychological factors including depression, anxiety, and pain catastrophizing, with measures of upper limb patient-reported and performance-based disability, in patients with CR, and compare the obtained results with our similar study on CTS.

Methods

In a cross-sectional study, we recruited 92 patients with CR, and investigated their disability level using patient-reported questionnaires (Quick Disabilities of the Arm, Shoulder and Hand (DASH) and pain Likert Scale) and by measuring grip and pinch strength. We also assessed their psychological status with Hospital Anxiety and Depression Scale questionnaire for depression (HADS-D) and anxiety (HADS-A) and also Pain Catastrophizing Scale (PCS) tools. We performed correlational coefficient analysis between disability and psychological scores and regression analysis of dependent variables (Pain, DASH, grip and pinch scores) and independent (psychological) variables. Finally, Z observed value was calculated to compare correlational coefficients between two diseases of CTS and CR.

Results

The results of the correlational coefficient analysis indicate that all three HADS-A, HADS-D and PCS scores correlated with DASH score (r = 0.49, 0.37, 0.38 for HADS-A, HADS-D and PCS, respectively; p < 0.001 for all three). HADS-A also significantly correlated with VAS pain score (r = 0.41, P < 0.001) and grip strength (r = − 0.25, P = 0.016). Linear regression analysis revealed that anxiety has a notable value for DASH and VAS pain scores as well as grip strength. Fisher’s r correlation coefficient to z transformation, revealed that there was no difference between two diseases of CTS and CR in terms of the resulted r coefficients from correlational coefficient analysis between disability and psychological distress.

Conclusion

It is concluded that psychological disorders are associated with disability in CR patients, with anxiety also correlating with objective disability parameter of grip strength. Finally, both CTS and CR patients’ disabilities associate with anxiety, depression, and catastrophysing thinking in a similar manner.

Larger pain extent is associated with greater pain intensity and disability but not with general health status or psychosocial features in patients with cervical radiculopathy

Pain as a result of cervical radiculopathy (CR) can be widespread, nondermatomal and individually specific, but the association between pain extent and other clinical features has never been explored. The objective of this study is to investigate whether pain extent relates to clinical variables including pain intensity in addition to health indicators including disability, general health, depression, somatic anxiety, coping strategies or self-efficacy.An observational cohort study was conducted. Participants were recruited from 4 hospital spinal centres in Sweden. Pain extent was quantified from the pain drawings of 190 individuals with cervical disc disease, verified with magnetic resonance imaging (MRI) and compatible with clinical findings (examined by a neurosurgeon), that show cervical nerve root compression. Pain extent was evaluated in relation to neck pain, arm pain, and headache intensity. Multiple linear regression analysis were then used to verify whether pain extent was associated with other health indicators including disability, health-related quality of life, depression, somatic anxiety, coping strategies and self-efficacy.Pain extent was directly related to neck, arm and headache pain intensity (all P < .01). Multiple linear regression revealed that pain extent was significantly associated only to the level of perceived disability (P < .01).Increased pain extent in people with CR is associated with higher headache, neck and arm pain intensity, and disability but not measures of general health, depression, somatic anxiety, coping strategies or self-efficacy.
