Cervical Spine Manipulation Remains SAFE
Each year, new research reinforces the same conclusion: chiropractic spinal manipulation poses no greater risk than other forms of treatment.
“[Data] supports the use of SMT as an effective and safe intervention for reducing pain, improving Cervical ROM, and decreasing disability in patients with acute neck pain” (2) Diao et al. Systematic Reviews. May 2025 [https://link.springer.com/article/10.1186/s13643-025-02855-7]
This echoes a systematic review from last year: “no statistically significant difference in AEs [Adverse Events] between manipulation and control groups. All reported AEs were mild (e.g. temporary pain aggravation, soreness); no moderate or serious AEs occurred… HVLA cervical manipulation does not increase the risk of mild or moderate AEs compared to controls.” (3) [Pankrath et al. Pain Physician. 2024 https://opus.hs-osnabrueck.de/files/7486/Adverse.pdf
And a new systematic review confirms what several prior biomechanical studies have shown: “consistent evidence that cervical SMT induces less strain on the vertebral artery, particularly within the V3 segment, compared to passive cervical ROM.” (4) Fagundes C et al. Clinical Biomechanics. Dec 2025. https://www.sciencedirect.com/science/article/pii/S026800332500258X
"Passive range of motion testing produced strains in the vertebral artery were 5.3 times (C0-C1), 7.2 times (C1-C2), and 3.7 times (C2-C3) greater than the corresponding strains during chiropractic spinal manipulation, suggesting that strains in the vertebral artery during chiropractic spinal manipulation were much smaller than the strains that can occur during normal everyday movements of the head and neck. Furthermore, vertebral artery strains in the pre-manipulative phase did not contribute to the peak strains on the contralateral vertebral artery and helped reduce strains on the ipsilateral side."

And… an extensive Medicare study of neck pain patients also confirmed: “Management with chiropractic care was associated with lower rates of adverse events than primary medical care. The prescription drug therapy group had the highest risk of any measured adverse outcome.” (5) Whedon et al. JMPT. Sept 2025 https://www.sciencedirect.com/science/article/pii/S0161475425000028
BMJ Meta-Analysis Confirms the Effectiveness of Neck Manipulation
A BMJ systematic review analyzing over 100 prior RCTs on neck pain concluded: “...multimodal treatment [the combined use of two or more musculoskeletal manipulations] was the most effective for reducing neck disability, whereas manipulation was the most effective for improving cervical range of motion.” (6) Gong et al. BMJ Open. Oct 2025. https://bmjopen.bmj.com/content/15/10/e098682.abstract
Cervical Manipulation Outperforms Other Therapies for Cervicogenic Headache
A meta-analysis of manual therapies for cervicogenic headache concluded:
“[Cervical Spine Manipulation] may be the most effective short-term intervention for reducing pain and disability compared to mobilization, massage, and exercise.” (1) Xu et al. Frontiers in Neurology. May 2025 https://www.frontiersin.org/journals/neurology/articles/10.3389/fneur.2025.1566764/full
