What could be a sign of adverse reaction during electrical stimulation?

A sign of adverse reaction during electrical stimulation is persistent swelling at the electrode site. This condition likely indicates that the body is reacting negatively to the electrical stimulation, potentially due to irritation, improper electrode placement, or too high of an intensity level. While some degree of temporary swelling might be normal, especially shortly after the treatment, persistent swelling suggests that inflammatory processes are being triggered and could result in further complications if not addressed.

In contrast, increased muscle relaxation, improved range of motion, and temporary muscle fatigue can all be typical responses to electrical stimulation therapy, reflecting its intended therapeutic effects. Increased muscle relaxation and improved range of motion indicate that the therapy is successfully helping to relieve tension and facilitate movement. Temporary muscle fatigue can also occur as a normal response to stimulation, often indicating that the muscles have been engaged and are in recovery. Therefore, these responses are generally seen as positive outcomes rather than signs of adverse reactions.
