EMG biofeedback measures the electrical activity in muscles. It is used for tension headaches, bruxism, neuralgia, relaxation, stress management, performance enhancement, and therapy for muscle dysfunctions.

This method correlates with vasoconstriction and vasodilation of blood vessels. It complements psychotherapy and is used alongside relaxation techniques for stress management, migraines, and high blood pressure.

EMG biofeedback involves the registration of electrical activity in the muscles. It is used for tension headaches, bruxism, neuralgia, relaxation, stress management, performance enhancement, and the therapy of muscle dysfunctions.

Breathing biofeedback is the only type of biofeedback that is fully and always under our voluntary control. The goal of the training is to practice breathing techniques to learn the proper modulation of the sympathetic and parasympathetic nervous systems (regulating arousal states). It is used for self-regulation, relaxation, stress management, performance enhancement, anxiety, and phobias.

Heart Rate Variability (HRV) biofeedback is a type of biofeedback that uses two sensors: a breathing sensor and a Blood Volume Pulse (BVP) sensor that measures blood flow in the vessels. The purpose is to gain voluntary control over the level of activation of the autonomic nervous system—high pulse rates are associated with anxiety, fear, and stress (activating the sympathetic part), which reduces blood flow to peripheral organs. By lowering the heart rate, we decrease the number of beats per minute, while increasing it raises heart rate variability and synchronizes with breathing. The goal of the training is to enhance heart rate variability and coherence between heart rate and breathing (aligning breathing with heartbeats) to achieve balance between the sympathetic and parasympathetic nervous systems. This method is used to improve self-regulation, emotional and behavioral control, relaxation, stress management, depression, anxiety, fears, and performance enhancement.
