Definition of Direct Biofeedback: Looking at biological information exactly as it is occurring through the body. Examples include: * Heart rate monitors. * Oxygen saturation ( $O_2$ sat) monitors. * Temperature gauges (e.g., forehead thermometers reading temperature directly).
Definition of Transformed Biofeedback: The process of converting biological activity into a different form, such as a visual or auditory representation on a device. * The primary example is Electromyography (EMG), which transforms electrical muscle activity into visual signals to show what is occurring within a muscle.
General Purpose: Biofeedback is used to facilitate biological processes within muscle tissue. * Goals include increasing muscle activity, decreasing muscle activity, or facilitating neuromuscular coordination. * It provides the patient with "knowledge of results," allowing them to see how they are performing and adjust accordingly. * Technically, biofeedback is not a physical agent because it does not apply energy (thermal, mechanical, or electromagnetic) to the body; rather, it uses electrical sensors to measure internal activity. However, it is typically grouped with therapeutic techniques and modalities.

Electrode Configuration: Standard setups involve three electrodes: two active and one ground. * Active Electrodes: These measure the actual electrical activity of the muscle. * Ground Electrode: This helps eliminate background noise or electrical interference. *
