What is an advantage of using surface electrodes in biofeedback?

Using surface electrodes in biofeedback offers several advantages, and one of the most significant is their ease of application and general acceptance by patients. Surface electrodes are simple to place on the skin, which means that practitioners can quickly set up the biofeedback session without complicated procedures. This user-friendliness is particularly important in clinical settings where time efficiency is crucial. Additionally, because surface electrodes are non-invasive, they are often more comfortable for patients, leading to better cooperation and adherence to therapy.

In contrast, options related to sensitivity for deep muscle detection or detecting activity from deep muscle layers do not apply to surface electrodes, as they are primarily designed for recording signals from superficial muscle activity. They may not be suitable for deep muscle detection, as that typically requires deeper electrode placement or different sensing techniques. While preparation might vary depending on the specific treatment, good practice often involves some minimal preparation to ensure accurate readings and optimal electrode adhesion, which contradicts the notion that no preparation is required.
