Manual physical therapy for neck disorders: an umbrella review.

INTRODUCTION

Neck pain is a common musculoskeletal disorder, with a prevalence rate (age-standardized) of 27.0 per 1000 in 2019. Approximately 50-85% of individuals with acute neck pain do not experience complete resolution of symptoms, experiencing chronic pain. Manual therapy is a widely employed treatment approach for nonspecific neck pain (NSNP), cervical radiculopathy (CR) and cervicogenic headaches (CGH). This umbrella review synthesized systematic reviews examining manual physical therapy for individuals with cervical disorders.

METHODS

Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed with Prospero registration (CRD42022327434). Four databases were searched from January 2016 to May 2023 for systematic reviews with or without meta-analysis examining manual therapy for individuals with neck pain of any stage. Interventions included any manual physical therapy of the cervical or thoracic spine as well as neuromobilization of the upper quarter. Primary outcomes included pain and disability. Two reviewers screened for eligibility and completed data extraction. Methodological quality was assessed using the Assessment of Multiple Systematic Reviews (AMSTAR 2) tool.

RESULTS

A total of 35 SRs were included: 15 NSNP, 7 cervical radiculopathy, 9 CGH and 4 samples with combined diagnoses. AMSTAR 2 ratings of the SRs support high confidence in results for 10 reviews, moderate confidence in 12 reviews and low to critically low confidence in 13 reviews. For NSNP, there was high confidence in the results showing manual therapy combined with exercise was superior to either treatment in isolation. In cervical radiculopathy, neural mobilization, distraction, soft tissue treatment and mobilization/manipulation to cervical and thoracic spine were supported with moderate confidence in results. For CGH, there was high confidence in the results supporting the use of cervical spine mobilization/manipulation, soft tissue mobilization, and manual therapy combined with exercise. Original authors of SRs reported varying quality of primary studies with lack of consistent high quality/low risk of bias designs.

CONCLUSION

Manual therapy plus exercise, cervical or thoracic mobilization and manipulation, neuromobilization, and other types of manual therapy were supported as effective interventions in the management of pain and disability for individuals with NSNP, CGH, or CR in the short-term.
