When using iontophoresis for lateral epicondylitis, how often should the therapist check the skin during treatment?

When utilizing iontophoresis for lateral epicondylitis, it is essential for the therapist to monitor the skin condition to prevent any adverse reactions such as irritation, burns, or redness from the electrical stimulation associated with the treatment. Checking the skin every 3 to 5 minutes strikes an appropriate balance between ensuring patient safety and allowing effective delivery of the medication through iontophoresis.

This frequency provides the therapist with timely information about the skin's reaction to the treatment. If any negative changes occur, adjustments can be made quickly, such as modifying the intensity or duration of the treatment, or even halting the session if necessary.

Other options either propose checks that occur too infrequently, potentially missing any negative skin reactions, or too frequently, which could disrupt the treatment. Hence, the 3 to 5-minute interval is considered best practice for ensuring patient safety and treatment efficacy.
