Chiropractic injuries are commonly framed as rare events, but reported outcomes show more than a footnote to routine visits. Vertebrobasilar stroke risk after manipulation is estimated at 1.46 per 100,000 patients, and serious complications from cervical manipulation are estimated at about 1 in 1 million manipulations. The following sections break down where adverse effects occur and how often soreness, neurologic injury, and other outcomes show up.
Key Takeaways
- Chiropractic stroke risk no higher than PCP visits
- Minor adverse events occur in 33% to 60% of chiropractic visits
- 117 stroke cases linked to chiro 1995-2000 Canada
- Elderly have 3x higher complication severity
- 20% of strokes lead to permanent disability
- 75% of AEs are musculoskeletal soreness
Chiropractic care can significantly reduce injury recovery times, showing strong improvements across common chiropractic-related concerns.
