What can occur if a galvanic electrode is not applied with regular pressure?

When a galvanic electrode is not applied with regular pressure, one of the primary concerns is the potential for uneven distribution of current across the treatment area. This uneven pressure can create hot spots where the current concentration is much higher, often resulting in skin irritation or burning at those sites. The skin cannot tolerate excessive heat or electrical stimulation, which can lead to discomfort or injury.

For instance, if an area of skin experiences excessive pressure from the electrode, it could generate more heat than the surrounding areas. This localized overheating can damage skin tissues, leading to burns. Thus, it is crucial for practitioners to maintain consistent pressure when using galvanic electrodes to ensure a safe and effective treatment experience for clients.

Other options, while they may seem relevant, do not directly address the immediate risks associated with the lack of regular pressure in this context. They pertain to broader concerns, such as treatment efficacy or operator safety, which are secondary to the immediate effects on the client's skin.
