Manual Therapy With and Without Vestibular Rehabilitation for Cervicogenic Dizziness: A Systematic Review Reidar P Lystad, Gregory Bell, Martin Bonnevie-Svendsen and Catherine V Carter Chiropractic & Manual Therapies 2011 (Sep 18) https://www.ncbi.nlm.nih.gov/pubmed/26362851 Conclusion: There is moderate evidence to support the use of manual therapy, in particular spinal mobilization and manipulation, for cervicogenic dizziness.
