Prognostic Factors for Improvement in Pain and Disability after Multidisciplinary Rehabilitation in Patients with Chronic Neck Pain

Abstract Background: Recent clinical studies support the effectiveness of chronic neck pain specific multidisciplinary biopsychosocial rehabilitation programmes, but prognostic factors for improvement in pain and disability are unknown. The aim of this study was to identify predictors of improvement in patients with chronic neck pain after participation in a three-week multidisciplinary biopsychosocial rehabilitation programme. Methods: In this observational prospective cohort study patients were assessed at the beginning and the end of a multidisciplinary biopsychosocial rehabilitation programme. Inclusion for participation in the rehabilitation programme depended upon an interdisciplinary pain assessment. Consecutive patients who fulfilled the inclusion criteria were invited to participate in the study. A total of 112 patients participated. The primary outcomes, pain and disability, were measured by the Northern American Spine Society questionnaire (NASS), quantified by effect sizes (ES), and modelled with various co-factors. Secondary outcomes were mental health measured by the Short-Form 36 and total cervical active range of motion measured by a reliable, validated cervical range of motion instrument.Results: Patients’ mean age was 59.7 years (standard deviation=10.8); 70.5% were female. Patients improved significantly (p<0.001) in pain+disability (ES=0.56), mental health (ES=0.45) and cervical range of motion (ES=0.39). Prognostic factors for improvement in pain+disability were worse baseline scores (partial, adjusted correlation r=0.41, p<0.001), higher age (r=0.22, p=0.024), higher improvement in cervical range of motion (r=0.21, p=0.033) and higher improvement in mental health scale (r=0.20; p=0.047). Conclusions: Better outcomes for patients with improvement in neck range of motion, improvement of mental health, and higher age support the use of multidisciplinary biopsychosocial rehabilitation that combines physical and psychological treatment components. Furthermore, the results suggest that older patients may improve more compared to younger patients.

Abstract Background Recent clinical studies have demonstrated the effectiveness of specific, multidisciplinary, bio-psychosocial, rehabilitation programmes for chronic neck pain. However, prognostic factors for the improvement of pain and disability are mostly unknown. Therefore, the aim of this study was to explore prognostic factors associated with improvements in chronic neck pain following participation in a three-week, multidisciplinary, bio-psychosocial, rehabilitation programme. Methods In this observational, prospective cohort study, a total of 112 patients were assessed at the beginning, end, and 6 months following the completion of a multidisciplinary, bio-psychosocial, rehabilitation programme. Inclusion for participation in the rehabilitation programme depended upon an interdisciplinary pain assessment. The primary outcome was neck pain and disability, which was measured using the Northern American Spine Society questionnaire for pain+disability and was quantified with effect sizes (ES). Multivariable linear regression analyses were used to explore potential prognostic factors associated with improvements in pain and disability scores at discharge and at the 6-month follow-up period. Results The mean age of the patients was 59.7 years (standard deviation = 10.8), and 70.5% were female. Patients showed improvement in pain+disability at discharge (ES = 0.56; p < 0.001), which was sustained at the 6-month follow-up (ES = 0.56; p < 0.001). Prognostic factors associated with improvement in pain+disability scores at discharge included poor pain+disability baseline scores (partial, adjusted correlation r = 0.414, p < 0.001), older age (r = 0.223, p = 0.024), a good baseline cervical active range-of-motion (ROM) (r = 0.210, p < 0.033), and improvements in the Short-form 36 mental health scale (r = 0.197; p = 0.047) and cervical ROMs (r = 0.195, p = 0.048) from baseline values. Prognostic factors associated with improvements in pain+disability at the 6-month follow-up were similar and included poor pain+disability baseline scores (partial, adjusted correlation r = 0.364, p < 0.001), improvements in the Short-form 36 mental health scale (r = 0.232; p = 0.002), cervical ROMs (r = 0.247, p = 0.011), and better cervical ROM baseline scores. However, older age was not a factor (r = 0.134, p = 0.172). Conclusions Future prognostic models for treatment outcomes in chronic neck pain patients should consider cervical ROM and mental health status. Knowledge of prognostic factors may help in the adoption of individualized treatment for patients who are less likely to respond to multidisciplinary rehabilitation.
