Biofeedback

A process that uses electronic instruments to measure physiological activity and provide real-time feedback to help individuals learn to control bodily functions, such as heart rate, muscle tension, or skin temperature.

Related: Neurofeedback, HRV Biofeedback, Pelvic Muscle Dysfunction Biofeedback
Operant Conditioning

A learning process where behaviors are modified through reinforcement or punishment; in biofeedback, patients learn to alter physiological responses by receiving rewards (e.g., a tone) for desired changes.

Related: Biofeedback, Reinforcement
Self-Regulation

The ability to manage one's own physiological and emotional states through conscious effort and learned techniques, often enhanced by biofeedback training to achieve homeostasis and improve performance.

Related: Biofeedback, Homeostasis
Psychophysiology

The scientific study of the relationship between physiological processes and psychological phenomena, providing the theoretical foundation for biofeedback by linking bodily responses to mental states.

Related: Biofeedback, Autonomic Nervous System
Autonomic Nervous System

The part of the nervous system that regulates involuntary body functions, including heart rate, digestion, and respiration; it has sympathetic and parasympathetic branches that biofeedback aims to balance.

Related: Sympathetic Nervous System, Parasympathetic Nervous System
Sympathetic Nervous System

The branch of the autonomic nervous system responsible for the fight-or-flight response, increasing heart rate, blood pressure, and muscle tension; biofeedback often aims to reduce excessive sympathetic activation.

Related: Autonomic Nervous System, Parasympathetic Nervous System
Parasympathetic Nervous System

The branch of the autonomic nervous system that promotes rest and digestion, lowering heart rate and promoting relaxation; biofeedback training often seeks to enhance parasympathetic activity for stress reduction.

Related: Autonomic Nervous System, Sympathetic Nervous System
Homeostasis

The body's tendency to maintain internal stability and balance among physiological systems; biofeedback helps individuals restore homeostasis by learning to modulate dysregulated responses.

Electromyography (EMG)

A technique that measures electrical activity produced by skeletal muscles; in biofeedback, EMG is used to help patients learn to relax or tense specific muscle groups, including pelvic floor muscles.

Related: Pelvic Muscle Dysfunction Biofeedback, Muscle Tension
Neurofeedback

A type of biofeedback that uses electroencephalography (EEG) to measure brainwave activity and provide feedback to help individuals learn to regulate brain function, often used for conditions like ADHD or anxiety.

Related: Electroencephalography (EEG), Brainwave Bands
Electroencephalography (EEG)

A method of recording electrical activity of the brain using electrodes placed on the scalp; it is the primary measurement tool in neurofeedback, providing real-time data on brainwave patterns.

Related: Neurofeedback, Brainwave Bands
Brainwave Bands

Frequency ranges of EEG activity, including delta, theta, alpha, beta, and gamma; neurofeedback protocols target specific bands to address conditions such as anxiety, attention deficits, or sleep issues.

Related: Neurofeedback, Electroencephalography (EEG)
Alpha Waves

EEG oscillations in the 8–12 Hz range, associated with relaxed wakefulness and calm focus; neurofeedback often aims to increase alpha activity to promote relaxation and reduce stress.

Related: Brainwave Bands, Neurofeedback
Theta Waves

EEG oscillations in the 4–8 Hz range, linked to drowsiness, light sleep, and meditative states; abnormal theta activity may be targeted in neurofeedback for attention or emotional regulation.

Related: Brainwave Bands, Neurofeedback
Beta Waves

EEG oscillations in the 13–30 Hz range, associated with active thinking, focus, and alertness; neurofeedback may aim to increase beta for attention or decrease it for anxiety reduction.

Related: Brainwave Bands, Neurofeedback
Sensorimotor Rhythm (SMR)

A specific EEG rhythm in the 12–15 Hz range over the sensorimotor cortex, associated with calm focus and motor inhibition; SMR neurofeedback is used for ADHD and epilepsy.

Related: Beta Waves, Neurofeedback
Neuroplasticity

The brain's ability to reorganize itself by forming new neural connections throughout life; neurofeedback is thought to harness neuroplasticity to produce lasting changes in brain function.

Related: Neurofeedback, Operant Conditioning
HRV Biofeedback

A technique that uses heart rate variability (HRV) feedback to help individuals learn to regulate their autonomic nervous system, often through paced breathing to increase HRV and improve stress resilience.

Related: Heart Rate Variability (HRV), Resonance Frequency
Heart Rate Variability (HRV)

The variation in time intervals between consecutive heartbeats (R-R intervals); higher HRV generally indicates better autonomic flexibility and stress resilience, and is a key metric in HRV biofeedback.

Related: HRV Biofeedback, Respiratory Sinus Arrhythmia
Resonance Frequency

The breathing rate (typically around 5–6 breaths per minute) at which heart rate variability is maximized due to resonance between respiratory and cardiovascular rhythms; used in HRV biofeedback training.

Related: HRV Biofeedback, Paced Breathing
Paced Breathing

A technique where an individual breathes at a specific rate, often guided by a pacer, to enhance HRV and achieve autonomic balance; commonly used in HRV biofeedback to reach resonance frequency.

Related: Resonance Frequency, HRV Biofeedback
Respiratory Sinus Arrhythmia

The natural variation in heart rate that occurs during breathing, with heart rate increasing during inhalation and decreasing during exhalation; it is a key component of HRV and reflects parasympathetic activity.

Related: Heart Rate Variability (HRV), Parasympathetic Nervous System
Coherence

In HRV biofeedback, a state of psychophysiological synchronization where breathing, heart rate, and blood pressure rhythms align, often associated with positive emotional states and improved autonomic function.

Related: HRV Biofeedback, Resonance Frequency
Low-Frequency (LF) Power

A frequency-domain measure of HRV in the 0.04–0.15 Hz range, reflecting both sympathetic and parasympathetic influences; often used to assess autonomic balance in HRV biofeedback.

Related: Heart Rate Variability (HRV), High-Frequency (HF) Power
High-Frequency (HF) Power

A frequency-domain measure of HRV in the 0.15–0.40 Hz range, primarily reflecting parasympathetic activity and respiratory sinus arrhythmia; higher HF power indicates greater vagal tone.

Pelvic Muscle Dysfunction Biofeedback

A specialized form of biofeedback that uses sensors to measure pelvic floor muscle activity, helping patients learn to correctly contract and relax these muscles to treat conditions like incontinence or pelvic pain.

Related: Electromyography (EMG), Pelvic Floor Muscle Training
Pelvic Floor Muscles

A group of muscles that form a sling-like structure at the base of the pelvis, supporting pelvic organs and controlling urination and defecation; their dysfunction can lead to incontinence or prolapse.

Related: Pelvic Muscle Dysfunction Biofeedback, Kegel Exercises
Kegel Exercises

Exercises that involve contracting and relaxing the pelvic floor muscles to strengthen them; biofeedback is often used to teach correct technique and ensure proper muscle isolation.

Bladder Training

A behavioral technique involving scheduled voiding and gradual extension of time between urinations to improve bladder control; often combined with pelvic floor biofeedback for incontinence management.

Dyssynergia

A condition where muscles that should relax during a function instead contract, such as paradoxical contraction of the pelvic floor during urination or defecation; biofeedback can help retrain coordination.
