Psychophysiological biofeedback system

Psychophysiological biofeedback systems are medical devices that measure and provide real-time feedback on involuntary bodily functions like heart rate, muscle tension, or brain activity. Clinically, they help patients gain voluntary control over these functions—often for stress reduction, pain management, or rehabilitation—by training awareness and response through visual or auditory cues.

These systems typically require regulatory approval as they combine hardware (sensors, electrodes) and software for patient monitoring. They are usually supplied as integrated kits or paired with standard computers, with compliance varying by jurisdiction based on risk factors like data accuracy and patient interaction. Always check local regulations before use or distribution.
