When a massage therapist tried to treat the headaches she suffered after a 2006 car crash with acupuncture, however, he set off a cascade of health problems that would shatter Ms. Ribble-Orr’s sports-centred life — and raise questions about the popular needle therapy.

The therapist accidentally pierced Ms. Ribble-Orr’s left lung during acupuncture treatment that was later deemed unnecessary and ill-advised, causing the organ to collapse and leaving it permanently damaged. An Ontario court has just upheld the one-year disciplinary suspension imposed on therapist Scott Spurrell, rejecting his appeal in a case that highlights a rare but well-documented side effect of acupuncture.

Mr. Spurrell, who learned the ancient Chinese art on weekends at a local university, had no reason to stick the needle in his patient’s chest, and had wrongly advised Ms. Ribble-Orr that the chest pain and other symptoms she reported later were likely just from a muscle spasm, a discipline tribunal ruled.
