ABSTRACT Although neck pain is a common source of disability, little is known about its incidence and course. We conducted a population-based cohort study of 1100 randomly selected Saskatchewan adults to determine the annual incidence of neck pain and describe its course. Subjects were initially surveyed by mail in September 1995 and followed-up 6 and 12 months later. The age and gender standardized annual incidence of neck pain is 14.6% (95% confidence interval: 11.3, 17.9). Each year, 0.6% (95% confidence interval: 0.0-1.1) of the population develops disabling neck pain. The annual rate of resolution of neck pain is 36.6% (95% confidence interval: 32.7, 40.5) and another 32.7% (95% confidence interval: 25.5, 39.9) report improvement. Among subjects with prevalent neck pain at baseline, 37.3% (95% confidence interval: 33.4, 41.2) report persistent problems and 9.9% (95% confidence interval: 7.4, 12.5) experience an aggravation during follow-up. Finally, 22.8% (95% confidence interval: 16.4, 29.3) of those with prevalent neck pain at baseline report a recurrent episode. Women are more likely than men to develop neck pain (incidence rate ratio=1.67, 95% confidence interval 1.08-2.60); more likely to suffer from persistent neck problems (incidence rate ratio=1.19, 95% confidence interval 1.03-1.38) and less likely to experience resolution (incidence rate ratio=0.75, 95% confidence interval 0.63-0.88). Neck pain is a disabling condition with a course marked by periods of remission and exacerbation. Contrary to prior belief, most individuals with neck pain do not experience complete resolution of their symptoms and disability.

    ABSTRACT: The aim of this study was to analyse the effect of an 8-week multimodal physiotherapy programme (MPP), integrating physical land-based therapeutic exercise (TE), adapted swimming and health education, as a treatment for patients with chronic non-specific neck pain (CNSNP), on disability, general health/mental states and quality of life. 175 CNSNP patients from a community-based centre were recruited to participate in this prospective study. 60-minute session (30 minutes of land-based exercise dedicated to improving mobility, motor control, resistance and strengthening of the neck muscles, and 30 minutes of adapted swimming with aerobic exercise keeping a neutral neck position using a snorkel). Health education was provided using a decalogue on CNSNP and constant repetition of brief advice by the physiotherapist during the supervision of the exercises in each session. primary: disability (Neck Disability Index); secondary: physical and mental health states and quality of life of patients (SF-12 and EuroQoL-5D respectively). Differences between baseline data and that at the 8-week follow-up were calculated for all outcome variables. Disability showed a significant improvement of 24.6% from a mean (SD) of 28.2 (13.08) at baseline to 16.88 (11.62) at the end of the 8-week intervention. All secondary outcome variables were observed to show significant, clinically relevant improvements with increase ranges between 13.0% and 16.3% from a mean of 0.70 (0.2) at baseline to 0.83 (0.2), for EuroQoL-5D, and from a mean of 40.6 (12.7) at baseline to 56.9 (9.5), for mental health state, at the end of the 8-week intervention. After 8 weeks of a MPP that integrated land-based physical TE, health education and adapted swimming, clinically-relevant and statistically-significant improvements were observed for disability, physical and mental health states and quality of life in patients who suffer CNSNP. The clinical efficacy requires verification using a randomised controlled study design. NCT02046876.

    ABSTRACT: Background: Anterior Cervical Discectomy and Fusion (ACDF) is an effective treatment for disc herniations; but some studies demonstrated that in the untreated levels adjacent to a fusion, increased motion might lead to an increased risk of adjacent segment degeneration (ASD). On the other hand, methods of cervical Disc Arthroplasty (CDA) have improved. The aim of this study is to evaluate and compare the rate of ASD in patients who underwent ACDF or CDA cervical spine surgery.Methods and Materials: This prospective study was performed on 84 patients with cervical radiculopathy due to single-level disc herniation referred to hospitals in Tehran, Iran from June 2011 to December 2012. All subjects were randomly allocated to Group A or Group B to undergo ACDF or CDA, respectively. The validated Neck Disability Index (NDI) questionnaire was used to assess the cervicalneck pain. Results: The mean of age in Group A was 51.7 ± 9.1 years and in Group B was 49.3 ±9.2. The differences in cervical radiculopathy in the two groups were not statistically significant. The difference in mean Visual Analogue Scale (VAS) score in the two groups at each assessment time was statistically significant. Mean NDI score before the surgery was 46.9 ± 6.1 in group A, and 41.3 ±4.7 in group B. The mean NDI score improved significantly in group B. Twenty-seven of the patients in Group A experienced ASD at 12 months compared to one patient (2.3%) in Group B (P<0.05). Conclusions: According to the findings of this study, CDA leads to reduced VAS and NDI score compared to ACDF. Also increased ASD in ACDF was demonstrated when compared with CDA after 1-year follow-up.
