The analysis tracked 36 youngsters with chronic mild or moderate asthma. All subjects were aged 6 to 17 years. Over a 3-month period, patients received either chiropractic adjustments or "sham" adjustments. In addition, all study participants underwent medical treatment.
No difference was seen between chiropractic patients and controls in lung function or hyper-responsiveness. However, youngsters receiving chiropractic care "rated their quality of life substantially higher and their asthma severity substantially lower. These improvements were maintained at the 1-year follow-up assessment."
