The ECG method is more accurate than the PPG method in measuring heart rate variability. The statistical variability of that interbeat interval is what we call heart rate variability. The interbeat interval, divided into 60 seconds, determines the heart rate at that moment. The electrocardiogram (ECG) uses electrodes placed on the torso, wrists, or legs, to measure the electrical activity of the heart and measures the interbeat interval (distances between successive R-wave peaks in the QRS complex). This is because the PPG sensor is more sensitive than a thermistor to minute blood flow changes.
Risks and Benefits
Similarly, it could help you develop techniques to manage physiological changes and, consequently, relieve stress. All Biofeedback trainers must be Licensed Healthcare Professionals.

Chronic back pain
Biofeedback tries to teach you to control automatic body functions such as heart rate, muscle tension, breathing, perspiration, skin temperature, blood pressure, and even brain waves. Also found was high-confidence evidence that biofeedback as an adjunctive treatment for pelvic floor muscle training (PFMT) can result in both immediate- and long-term improvements in urinary incontinence for men after a prostatectomy as compared with PFMT alone. Biofeedback therapy can help you create a mind-body connection so you Biofeedback Therapy can control heart rate, breathing, perspiration, and other involuntary actions in your body. If you have a problem that is persistent and limits your normal activity, then ask your healthcare provider if biofeedback therapy may be an option for you. Deep breathing techniques can help a variety of conditions such as stress and anxiety, high blood pressure, or elevated heart rate.
International Patients
You will be getting continuous feedback from the biofeedback device, and your therapist can help you make changes to your reactions and emotions during the session. Then your therapist will guide you in a specific mental activity involving meditation, imagery, or breathing exercises. A typical biofeedback session will last between 30 and 60 minutes.

Tarchanoff showed that voluntary control of heart rate could be fairly direct (cortical-autonomic) and did not depend on “cheating” by altering breathing rate. BCIA certifies individuals meeting education and training standards in biofeedback and neurofeedback and progressively recertifies those satisfying continuing education requirements. BCIA offers biofeedback certification, neurofeedback (also called EEG biofeedback) certification, and pelvic muscle dysfunction biofeedback. The SBCNA offers an Annual Conference for professional continuing education as well as promoting biofeedback as an adjunct to the allied health professions.
When should I call my healthcare provider?
We often don’t consciously realize all the ways our body responds to things like pain, stress and anxiety. This will vary depending on your reason for getting biofeedback therapy. Healthcare providers don’t use biofeedback as a standalone treatment for most conditions. It can help manage conditions like chronic pain, anxiety and incontinence. A healthcare professional can help determine whether biofeedback is right for you, based on your health condition. According to StatPearls, the main potential risk of biofeedback is that the physical improvements experienced during biofeedback may decrease once the therapy stops.
With training and practice, biofeedback can be used to help people develop new skills that may help them to better cope or perform. Biofeedback is often considered a type of training rather than a treatment. Blood pressure biofeedback involves wearing a device that provides information about the patient’s blood pressure. Galvanic skin response, also known as skin conductance, is a type of biofeedback that involves measuring the amount of sweat on the surface of the skin. With heart rate variability biofeedback, patients wear a device connected to sensors in either the ears or fingers or sensors placed on the wrists, chest, or torso. Respiratory biofeedback involves wearing sensor bands around the chest and abdomen to monitor breathing rates and patterns.
You may not realize it, but when you have pain or are under stress, your body changes. During biofeedback, you’re connected to electrical pads that help you get information about your body. Don’t delay seeing a medical healthcare provider for a health issue, even if biofeedback helps you manage your condition. For example, someone with chronic pain may take medications and learn biofeedback. Most people use biofeedback along with other treatments. Biofeedback can help you feel more in control of your health and wellness.
What happens during biofeedback therapy?
- As your neurological system changes during therapy, the sensors detect this change, and you slowly gain control of your brain activity.
- Because it takes about 5 seconds for blood pressure to change after changes in heart rate (think of different amounts of blood flowing through the same sized tube), the baroreflex produces a rhythm in heart rate with a period of about 10 seconds.
- With biofeedback, you become aware of these bodily changes and learn to modify them.
- By Brett Sears, PTBrett Sears, PT, MDT, is a physical therapist with over 20 years of experience in orthopedic and hospital-based therapy.
- Meta-analysis of different biofeedback treatments have shown some benefit in the treatment of headaches and migraines and ADHD, though most of the studies in these meta-analyses did not make comparisons with alternative treatments.
- Behaviorism contends that it is possible to change the actions and functions of an organism by exposing it to a number of conditions or influences.
This designation requires multiple observational studies, clinical studies, waitlist-controlled studies, and within subject and intrasubject replication studies that demonstrate efficacy. Khazan and colleagues assigned functional abdominal pain syndrome, hyperhidrosis, and vasovagal syndrome to this category. This designation requires at least one study of sufficient statistical power with well-identified outcome measures but lacking randomized assignment to a control condition internal to the study. Khazan and colleagues (2023) assigned neurofeedback connectivity protocols for seizures to this category. Both methods lead to an improvement of FI, but comparisons of St Mark’s scores between the groups showed no differences in effect between treatments. The ratings for each disorder depend on the nature of research studies available on each disorder, ranging from anecdotal reports to double blind studies with a control group.
Slower breathing rates—those less than six breaths per minute—may be beneficial in lowering blood pressure. This device is worn on your chest and has a small wearable monitor that provides you feedback about the rate of your breathing. After monitoring, you get feedback about how your breathing changes during certain situations.
Changes in bio-impedance are generated by blood volume and blood flow and registered by a rheographic device. The brain blood flow technique is based on non-invasive method of measuring bio-impedance. Electrodes are attached to the skin at certain points on the head and permit the device to measure continuously the electrical conductivity of the tissues of structures located between the electrodes. Shallow, rapid, and effortful breathing lowers CO2, while deep, slow, effortless breathing increases it. Dysfunctional breathing behaviors include apnea (suspension of breathing), gasping, sighing, and wheezing.
- Eventually, you’ll learn how to control these functions on your own, without the biofeedback equipment.
- Once you finish your biofeedback sessions, you can return to your therapist’s office whenever you feel you need to.
- Although biofeedback has been used to treat a variety of health problems, there is mixed scientific evidence that it works for most of them.
- You will be getting continuous feedback from the biofeedback device, and your therapist can help you make changes to your reactions and emotions during the session.
Peper has similarly taught asthmatics who wheeze to better control their breathing. Engel and Chism (1967) operantly trained subjects to decrease, increase, and then decrease their heart rates (this was analogous to ON-OFF-ON EEG training). Taub (1999, 2006) demonstrated the clinical efficacy of constraint-induced movement therapy (CIMT) for the treatment of spinal cord-injured and stroke patients. Last, they wrote The Pathophysiology and Treatment of Functional Disorders (1974) that outlined their treatment of functional disorders. These clinicians applied EMG biofeedback to diverse functional problems like headache and hypertension. Basmajian demonstrated practical applications for neuromuscular rehabilitation, pain management, and headache treatment.
What are the potential benefits of this treatment?
She also helped popularize biofeedback by publishing a series of books, including New Mind, New body (1974) and Stress and the Art of Biofeedback (1977). Biofeedback therapy is also a commonly used and researched therapy for fecal incontinence, but the benefits are uncertain. In 2019, the National Institute for Health and Care Excellence recommended against the routine use of use biofeedback in managing urinary incontinence in women who can actively contract the pelvic floor. The perineometer, which is inserted into the vagina to monitor pelvic floor muscle contraction, satisfies all the requirements of a biofeedback device and enhances the effectiveness of popular Kegel exercises.
Many people are turning to complementary or alternative methods to improve health and wellness. Biofeedback complements medical care — it doesn’t replace it. Your healthcare provider can provide more insight into the frequency of sessions that’s best for you. But to experience potential benefits, you must actively participate in the therapy and have the motivation to learn and make changes. This can help improve pelvic floor strength and decrease urinary incontinence. For example, your child plays as a character and has to contract their pelvic floor muscles to avoid obstacles in the game.
Biofeedback techniques are often combined with other techniques like music therapy, virtual reality, and games. These measurements provide feedback to the monitor about how your body responds to different stimuli. The types of sensors and measurement tools used may depend on the type of biofeedback. A healthcare professional may attach several electrical sensors to your body, which are connected to a monitor. State laws regulating biofeedback practitioners may also vary, so consider checking your own state’s regulations before visiting a therapist.
Once you finish your biofeedback sessions, you can return to your therapist’s office whenever you feel you need to. For temperature biofeedback, the sensors may be attached to your fingertips or toes. The therapist will connect you to the biofeedback equipment. You will be introduced to the biofeedback equipment. If your doctor has not referred you to a biofeedback therapist, but you want to try biofeedback, call your doctor first to discuss the situation.
Because it takes about 5 seconds for blood pressure to change after changes in heart rate (think of different amounts of blood flowing through the same sized tube), the baroreflex produces a rhythm in heart rate with a period of about 10 seconds. This contradicts the traditional view that finger blood flow is controlled exclusively by sympathetic C-fibers. Clinicians at the Menninger Foundation coupled an abbreviated list of standard exercises with thermal biofeedback to create autogenic biofeedback. He examined the constraints on learning integrated (two autonomic responses change in the same direction) and differentiated (two autonomic responses change inversely) patterns of blood pressure and heart rate change.
