Final answer:
Misuse of electroacupuncture has been associated with avulsion fractures. The answer is option 1.
Step-by-step explanation:
Electroacupuncture is a form of acupuncture where a small electric current is passed between pairs of acupuncture needles. Misuse or improper application of electroacupuncture, such as excessive electrical stimulation, may lead to adverse effects, and avulsion fractures are among the reported complications.
An avulsion fracture occurs when a fragment of bone is torn away from the main bone mass, often at the site of a tendon or ligament attachment. Healthcare providers need to use electroacupuncture safely and within established guidelines to minimize the risk of complications.
