The unit transforms the data into a visual display and through seeing the pain responses, the client is taught to regulate his physiologic response and control pain through relaxation, imagery, or breathing exercises. This technique for pain control is known as:
• Therapeutic Touch (TT).
• transcutaneous electrical nerve stimulation (TENS).
• biofeedback.
