FAQ Biofeedback

Biofeedback is a scientifically validated training method in which body processes such as heart rate, skin conductance, muscle tension, breathing or temperature are measured and fed back in real time. Through this feedback, users learn to consciously perceive and deliberately influence bodily functions that are normally unconscious.

The method is based on the principle of operant conditioning: Desired changes (e.g., deeper breathing, lower skin conductance) are reinforced through positive signals. This creates a learning effect that can eventually be maintained without devices.

→ Detailed explanation: Biofeedback Introduction

Biofeedback measures and trains peripheral body functions such as skin conductance (EDA), skin temperature, heart rate variability (HRV), muscle tension (EMG) or breathing.

Neurofeedback is a specialized form of biofeedback that focuses on brain activity (EEG). It is primarily used for ADHD/ADD, epilepsy and other neurological conditions.

Both methods use the same basic principle – feedback of body signals for self-regulation – but differ in the measured parameter and areas of application.

Depending on the objective, different parameters are used:

Professional systems like the MindMaster BioNeuro can measure up to 13 channels simultaneously. For mobile use, Mindfield offers the eSense sensors (EDA, temperature, pulse, respiration).

Yes, biofeedback has been scientifically studied and validated for numerous areas of application:

• Migraine and tension headaches: Explicitly recommended in the AWMF guideline (030/057, 2025). Meta-analyses show 35–45 % reduction in attack frequency, comparable to propranolol (Nestoriuc & Martin, 2007).
• Stress management: HRV biofeedback improves autonomic regulation and reduces stress symptoms (Lehrer & Gevirtz, 2014).
• Substance use disorders: HRV biofeedback reduced consumption days by 64 % in a phase 2 RCT (Eddie et al., JAMA Psychiatry, 2025).
• Chronic pain: EMG biofeedback shows positive effects for back pain. VR-supported multi-sensor biofeedback (EDA + HRV + breathing) achieved 51 % pain reduction in fibromyalgia (Chittaro et al., 2025).
• Incontinence: EMG biofeedback for pelvic floor training is a guideline recommendation for urinary and fecal incontinence.
• Hypertension: HRV biofeedback protects cardiac patients during mental stress – demonstrated through cardiac imaging (JAMA Network Open, 2025).
• Anxiety disorders: Meta-analysis of 26 studies shows strong effects (Hedges’ g = −0.87) for neurofeedback in anxiety disorders (Russo et al., 2022).

Biofeedback is recommended as a complementary method in many medical guidelines and is classified as a safe, non-invasive approach.

Biofeedback is used as a complementary approach for a wide range of conditions:

• Stress management and burnout prevention – HRV and EDA training
• Migraine and tension headaches – Temperature and EMG feedback
• Chronic pain – EMG biofeedback for back, neck and jaw pain
• Urinary and fecal incontinence – Pelvic floor training with EMG feedback
• Anxiety disorders and PTSD – EDA and breathing feedback for emotion regulation
• Hypertension – HRV training for blood pressure regulation
• Sleep disorders – Relaxation training with various parameters
• Rehabilitation – EMG feedback after stroke or injuries
• Peak performance – Performance optimization in sports and professional settings

EMG biofeedback is an established method for strengthening the pelvic floor muscles and is used for urinary and fecal incontinence. Sensors measure pelvic floor muscle tension in real time, allowing patients to learn to target and control the correct muscles.

Suitable for:

• Women after childbirth (stress incontinence)
• Men after prostate surgery
• Older adults with pelvic floor weakness
• Preventive pelvic floor training

EMG biofeedback for incontinence is recommended in medical guidelines. Typically 10–20 sessions are performed, after which training can be continued independently. In Germany, statutory health insurance often covers the costs through a medical prescription (physiotherapy/occupational therapy).

Yes, particularly neurofeedback (EEG-based biofeedback) is used as a complementary approach for ADHD/ADD and has the most extensive evidence base. The goal is to train the brain areas associated with attention and impulse control.

Peripheral biofeedback can also support those with ADHD/ADD:

• HRV biofeedback: Improving self-regulation and stress management
• EDA biofeedback: Training arousal control

For ADHD/ADD, 20–40 sessions are typically recommended. Neurofeedback is often conducted within occupational therapy and can be covered by statutory health insurance in Germany through a prescription.

A typical biofeedback session lasts 30–60 minutes:

1. Preparation: Sensors are placed on the relevant body sites (e.g., fingers for EDA/temperature, chest for breathing, muscle for EMG). This is painless and non-invasive.
2. Training: The measured values are displayed on a screen or fed back acoustically. Through targeted exercises (breathing, relaxation, tension), the user learns to change the values in the desired direction.
3. Evaluation: The therapist or trainer reviews the results and adjusts the training.

Initial results often appear after 3–5 sessions, while lasting effects typically require several weeks of training.

The number of sessions depends on the application:

Regular practice is important. The learned techniques can be applied in daily life long-term to maintain the effects.

Yes, there are now mobile biofeedback devices for home use that are controlled via smartphone apps. These are particularly suitable for:

• Regular relaxation and stress training
• Supplementing professional therapy
• Monitoring training progress between sessions

Mindfield offers eSense sensors – mobile biofeedback devices for various parameters:

• eSense Skin Response – Skin conductance (stress, relaxation)
• eSense Temperature – Skin temperature (blood circulation)
• eSense Pulse – Heart rate variability (HRV)
• eSense Respiration – Breathing training

It is recommended to begin training with a qualified therapist or trainer before transitioning to self-guided practice.

Biofeedback is offered by various qualified professionals:

• Physiotherapists – especially for pain therapy and incontinence
• Occupational therapists – frequently for ADHD/ADD and stress management
• Psychotherapists – for anxiety, stress and psychosomatic conditions
• Physicians – especially neurologists and rehabilitation specialists
• Alternative practitioners with biofeedback training

Recognized training and certification bodies:

• Deutsche Gesellschaft für Biofeedback (DGBfb) – German Biofeedback Society: training and therapist directory
• Biofeedback Certification International Alliance (BCIA) – international standard

Biofeedback is typically prescribed by a physician or psychotherapist when used as part of a treatment plan.

Costs depend on whether professional sessions or home devices are used:

Professional sessions:

• Single session: approx. 50–150 € (depending on provider, region and duration)
• Total cost (10–20 sessions): approx. 500–3,000 €

Home devices:

• Mobile sensors (e.g., eSense): from approx. 150 € per sensor
• Professional multi-channel devices: from approx. 2,000 €

It is advisable to have an initial consultation before starting therapy, where the expected duration and costs are discussed.

Statutory health insurance (Germany): Biofeedback as a standalone therapy is not a standard covered service. However, biofeedback is frequently performed as part of occupational therapy, physiotherapy or behavioral therapy – which are covered services. With a medical prescription (e.g., for physiotherapy for incontinence or occupational therapy for ADHD/ADD), costs can be billed through statutory health insurance.

Private health insurance: Many private insurers reimburse biofeedback when there is a medical prescription and the treatment is medically justified – especially for migraine, chronic pain, incontinence or ADHD/ADD.

Self-pay: Those who do not want to wait for a therapy slot can pay for treatment privately or purchase a home device for self-guided training.

Recommendation: Clarify insurance coverage before starting therapy with your health insurer.

Yes, biofeedback is considered a safe, non-invasive and medication-free method. Only sensors are used to record body data – no stimulation, electrical current or medication is applied.

Biofeedback is suitable for people of all age groups, from children to seniors. Serious side effects have not been documented in the scientific literature.

Biofeedback is not a substitute for medical or psychotherapeutic treatment, but is used as a complementary method. Existing medications should not be changed without consulting a physician.

Biofeedback may be less effective in certain situations:

• Insufficient motivation: As with any training, the user’s active participation is crucial
• Unrealistic expectations: Biofeedback is not an instant remedy but a learning process that requires patience
• Lack of integration: The learned techniques need to be applied in daily life for lasting effects
• Unsuitable indication: Not every condition responds equally well to biofeedback – expert consultation is important

If unsure, a consultation with an experienced therapist or trainer is recommended to assess whether biofeedback is suitable for your individual situation.
