What is a potential risk of using TENS incorrectly?

Using Transcutaneous Electrical Nerve Stimulation (TENS) incorrectly can indeed lead to skin irritation. This occurs because the electrodes may be placed improperly, or the intensity and duration of the stimulation might be set too high, causing discomfort or damaging the skin. Skin irritation can present as redness, itching, or a rash at the site of electrode placement, potentially leading to further complications if not addressed. Proper skin care and monitoring for any adverse reactions are essential when utilizing TENS therapy to minimize risks.

While other options mention concerns that could hypothetically occur from improper use, they are not as directly associated with the immediate effects of TENS application as skin irritation. Increased pain might occur if TENS is not effective, but that doesn't relate directly to skin application. Muscle atrophy is a more chronic concern tied to lack of movement rather than immediate use of TENS. Delayed healing of wounds isn't a typical risk associated with TENS; in fact, TENS is sometimes used to manage pain during the healing process. Overall, skin irritation is the most immediate and likely risk when TENS is not used correctly.
