STUDY DESIGN: Prospective national survey. OBJECTIVE: To estimate the risk of serious and relatively minor adverse events following chiropractic manipulation of the cervical spine by a sample of U.K. chiropractors. SUMMARY OF BACKGROUND DATA: The risk of a serious adverse event following chiropractic manipulation of the cervical spine is largely unknown. Estimates range from 1 in 200,000 to 1 in several million cervical spine manipulations. METHODS: We studied treatment outcomes obtained from 19,722 patients. Manipulation was defined as the application of a high-velocity/low-amplitude or mechanically assisted thrust to the cervical spine. Serious adverse events, defined as "referred to hospital A&E and/or severe onset/worsening of symptoms immediately after treatment and/or resulted in persistent or significant disability/incapacity," and minor adverse events reported by patients as a worsening of presenting symptoms or onset of new symptoms, were recorded immediately, and up to 7 days, after treatment. RESULTS: Data were obtained from 28,807 treatment consultations and 50,276 cervical spine manipulations. There were no reports of serious adverse events. This translates to an estimated risk of a serious adverse event of, at worse approximately 1 per 10,000 treatment consultations immediately after cervical spine manipulation, approximately 2 per 10,000 treatment consultations up to 7 days after treatment and approximately 6 per 100,000 cervical spine manipulations. Minor side effects with a possible neurologic involvement were more common. The highest risk immediately after treatment was fainting/dizziness/light-headedness in, at worse approximately 16 per 1000 treatment consultations. Up to 7 days after treatment, these risks were headache in, at worse approximately 4 per 100, numbness/tingling in upper limbs in, at worse approximately 15 per 1000 and fainting/dizziness/light-headedness in, at worse approximately 13 per 1000 treatment consultations. CONCLUSION: Although minor side effects following cervical spine manipulation were relatively common, the risk of a serious adverse event, immediately or up to 7 days after treatment, was low to very low.

STUDY DESIGN. Prospective national survey. OBJECTIVE. To estimate the risk of serious and relatively minor adverse events following chiropractic manipulation of the cervical spine by a sample of U.K. chiropractors. SUMMARY OF BACKGROUND DATA. The risk of a serious adverse event following chiropractic manipulation of the cervical spine is largely unknown. Estimates range from 1 in 200,000 to 1 in several million cervical spine manipulations. METHODS. We studied treatment outcomes obtained from 19,722 patients.

RESULTS. Data were obtained from 28,807 treatment consultations and 50,276 cervical spine manipulations. There were no reports of serious adverse events. This translates to an estimated risk of a serious adverse event of, at worse ≈1 per 10,000 treatment consultations immediately after cervical spine manipulation, ≈2 per 10,000 treatment consultations up to 7 days after treatment and ≈6 per 100,000 cervical spine manipulations. Minor side effects with a possible neurologic involvement were more common. The highest risk immediately after treatment was fainting/dizziness/light-headedness in, at worse ≈16 per 1000 treatment consultations. Up to 7 days after treatment, these risks were headache in, at worse ≈4 per 100, numbness/tingling in upper limbs in, at worse ≈15 per 1000 and fainting/dizziness/light-headedness in, at worse ≈13 per 1000 treatment consultations.

Although minor side effects following cervical spine manipulation were relatively common, the risk of a serious adverse event, immediately or up to 7 days after treatment, was low to very low. © 2007 Lippincott Williams & Wilkins, Inc.
