Key Takeaway
Manual therapy combined with exercise provides better outcomes for neck pain than either alone, with moderate certainty evidence supporting multimodal approaches
Summary
This systematic review published in the Journal of Orthopaedic & Sports Physical Therapy examined the effectiveness of manual therapy techniques including spinal manipulation for neck pain. The review synthesized evidence from multiple randomized controlled trials.
The key finding was that manual therapy combined with exercise therapy produced better outcomes than either intervention alone. Spinal manipulation showed moderate evidence of benefit for reducing neck pain intensity and improving function, particularly when integrated into a multimodal treatment approach.
The review emphasizes that manual therapy should not be used in isolation but rather as part of a comprehensive approach that includes active exercise and patient education. This aligns with current clinical practice guidelines that recommend combined approaches for neck pain management.
Methods
Systematic review searching multiple databases for RCTs evaluating manual therapy including spinal manipulation for neck pain. Included studies of adults with acute, subacute, or chronic neck pain. Assessed various manual therapy techniques including high-velocity thrust manipulation and mobilization. Evidence quality graded using GRADE criteria. Outcomes included pain intensity, disability, and function.
Key Results
Manual therapy combined with exercise showed moderate evidence of superiority over manual therapy alone for pain reduction and functional improvement. SMT alone showed small to moderate effects on neck pain compared to controls. Multimodal approaches (SMT + exercise + education) consistently outperformed single-modality treatments. Effects were most pronounced in the short to medium term.
Limitations
Heterogeneity in manual therapy techniques and dosing protocols. Blinding challenges inherent to manual therapy research. Variable definitions of neck pain across studies. Many trials had small sample sizes. GRADE certainty ranged from low to moderate. Difficulty isolating specific effects of manipulation from other treatment components in multimodal studies.
