Effects of Central Sensitivity Syndrome and Psychological Factors on the Clinical Features of Patients with Cervical Degenerative Disease: A Cross-Sectional Study

Methods@#Patients admitted for surgical treatment of CDD were recruited. The following patient-reported outcome measures were recorded on the day before the surgery: the Numerical Rating Scale (NRS) for neck pain intensity, Neck Disability Index (NDI), EuroQol 5-Dimensions (EQ-5D) survey, Central Sensitization Inventory (CSI), Pain Catastrophizing Scale, Tampa Scale for Kinesiophobia, and the Hospital Anxiety and Depression Scale were used. We performed three multiple regression analyses to investigate the effects of CSS and psychological factors on the clinical features. @*Results@#Multiple regression analysis revealed that CSI had a significant effect on NRS (β, 0.50; 95% confidence interval [CI], 0.29 to 0.71), NDI (β, 0.64; 95% CI, 0.45 to 0.82), and EQ-5D (β, −0.55; 95% CI, −0.75 to −0.35). Multiple regression analysis revealed that psychological factors did not exert a significant effect on the clinical features. @*Conclusions@#Our results demonstrated that CSI was able to identify the clinical features in CDD patients, suggesting that CSS does affect the clinical features of such patients.

Prognostic Value of Preoperative Coping Strategies for Pain in Patients with Residual Neuropathic Pain after Laminoplasty for Compressive Cervical Myelopathy

STUDY DESIGN: Single-center retrospective cohort study. PURPOSE: To clarify the prognostic value of preoperative coping strategies for pain due to compressive cervical myelopathy. OVERVIEW OF LITERATURE: Preoperative physical function, imaging and electrophysiological findings are known predictors of surgical outcomes. However, coping strategies for pain have not been considered. METHODS: Postoperative questionnaires, concerning health-related quality of life (HRQOL) and daily living activities, were sent to 78 patients with compressive cervical myelopathy who had suffered from neuropathic pain before laminoplasty, and been preoperatively assessed with respect to their physical and mental status and coping strategies for pain. Hierarchical multiple regression analysis was performed to clarify the extent to which the patient's preoperative coping strategies could explain the variance in postoperative HRQOL and activity levels. RESULTS: Forty-two patients with residual neuropathic pain after laminoplasty were analyzed by questionnaires (28 men, 14 women; mean age, 62.7+/-10.2 years; symptom duration, 48.0+/-66.0 months). The valid response rate was 53.8%. Hierarchical multiple regression analysis showed that preoperative coping strategies, which involved coping self-statements, diverting attention, and catastrophizing, were independently associated with postoperative HRQOL and activity level, and could explain 7% to 11% of their variance. Combinations of the coping strategies for pain and upper/lower motor functions could explain 26% to 36% of the variance in postoperative HRQOL and activity level. CONCLUSIONS: Preoperative coping strategies for pain are good predictors of postoperative HRQOL and activities of daily living in patients with postoperative residual neuropathic pain due to compressive cervical myelopathy.

The Association of Each Disability Based on the Three Sub-Categories of the Roland-Morris Disability Questionnaire during Hospitalization with Itself at 1 Year Postoperatively in Patients with Degenerative Lumbar Spinal Stenosis

STUDY DESIGN: A prospective study in a hospital. PURPOSE: To investigate whether each disability based on the three sub-categories of the Roland-Morris disability questionnaire (RDQ) during hospitalization is associated with itself at 1 year postoperatively in patients with degenerative lumbar spinal stenosis (LSS). OVERVIEW OF LITERATURE: Although the total score of the RDQ represents whole pain-related disabilities or health-related quality of life, it is a shortcoming that multi-dimensional changes in disabilities are difficult to understand when only using the RDQ. METHODS: Fifty-seven patients with LSS (men, 28; women, 29; 63.0+/-12.1 years) were included. Disabilities, pain intensity and depressive feelings were assessed at preoperation, discharge and 1 year postoperatively. RESULTS: The range of "mental and physical activities (MPA)," "functional movements on/around a bed (FM)" and "walking function (WF)" scores were 0 to 13 (median, 8), 0 to 6 (median, 6) and 0 to 4 (median, 3) at preoperation; 0 to 12 (median, 0), 0 to 6 (median, 0), and 0 to 4 (median, 0) at discharge; and 0 to 8 (median, 0), 0 to 5 (median, 0), and 0 to 4 (median, 0) at 1 year postoperatively, respectively. The following significant multiple regression equations were obtained: MPA at 1 year postoperatively=0.56 (MPA at discharge)-0.10 (depression at discharge)+0.90 (adjusted r2=0.41), FM at 1 year postoperatively=0.35 (MPA at discharge)-0.06 (depression at discharge)+0.40 (adjusted r2=0.45) and WF at 1 year postoperatively=0.59 (WF at discharge)-0.08 (depression at discharge)+0.63 (adjusted r2=0.29). CONCLUSIONS: In our LSS population, each disability based on MPA and WF at discharge is associated with itself in the future. Therefore, disabilities excluding functional movements are longitudinally independent.

Characteristics of Coping Strategies for Dysesthesia in Preoperative Patients with Compressive Cervical Myelopathy

STUDY DESIGN: A cross-sectional study. PURPOSE: This study aimed to clarify the characteristics of coping strategies for dysesthesia in preoperative patients with compressive cervical myelopathy. OVERVIEW OF LITERATURE: Cognitive behavioral therapy is effective for patients with chronic pain in terms of modifying their negative behavior. To effectively perform cognitive behavioral therapy, it is necessary to assess coping strategies because of their important roles in health-related quality of life. METHODS: Sixty-one preoperative patients with compressive cervical myelopathy (men, 39; women, 22; 61.0+/-11.6 years) participated. Coping strategies for dysesthesia (coping strategies questionnaire) and subjective symptoms (numerical rating scale for dysesthesia intensity and Japanese Orthopaedic Association cervical myelopathy evaluation questionnaire) were investigated. RESULTS: There were moderately significant correlations among the subcategory scores of the coping strategies questionnaire (Spearman's rank correlation coefficient [rs]< or =0.69, p<0.05); the praying/hoping and catastrophizing scores were significantly correlated with the numerical rating scale score of dysesthesia (both; rs=0.34, p<0.01); there were no correlations between the coping strategy scores and the cervical spine function and upper and lower extremity motor function scores of the Japanese Orthopaedic Association cervical myelopathy evaluation questionnaire; and there were no significant associations between the coping strategy scores and age, sex, and symptom duration. CONCLUSIONS: Various combinations of coping strategies for dysesthesia were selected in patients with compressive cervical myelopathy, and frequency of use of the coping strategies was not related to the perceived severity of cervical myelopathy or demographic factors.
