What Is Biofeedback and How Does it Work?


Biofeedback is a mind-body technique that can be used to help you control some of your body’s functions, such as heart rate or muscle tension. It is the process of increasing the awareness of the physiological functions of your own body. During a biofeedback session, you are connected to electrical sensors that provide you with information about your body to improve a health condition or physical performance.

How Does Biofeedback Work?

 During a biofeedback session, a therapist will attach electrical sensors to various parts of your body to monitor anything from your heart rate, breath, temperature, and/or muscle tension.

Who Uses Biofeedback?

Biofeedback training can be used by anyone, including athletes looking to improve their performance, or individuals going through rehabilitation after surgery or an injury. Physical therapists use biofeedback training to help their patients prevent future injuries, improve their strength, and restore muscle function.

Biofeedback in Rehabilitation

According to the National Library of Medicine, biofeedback has been used for over 50 years in rehabilitation to facilitate normal movement patterns after injury. Biofeedback therapy can help treat muscle tension, weakness, and lack of control. Here are some of the ways biofeedback has been used in rehabilitation:

  • Strengthens the pelvic floor

  • Optimizes treatments, improving muscle strength

  • Improves motor recovery

  • Restores muscle function

  • Prevents future injuries

  • Helps restore neurological functions

Biofeedback for Muscles

The Different Types of Biofeedback

The most common method of biofeedback are as follows:

  • Electromyography (EMG) biofeedback, which measures muscle tension over time.

  • Thermal biofeedback, which measures body temperature over time.

  • Electroencephalography, which measures brain wave activity over time.

EMG Biofeedback System and Rehabilitation

EMG biofeedback system measures the electrical activity produced by specific muscle groups. An example of such a tool that we recommend here at MoveU is the mTrigger® Biofeedback System. This system uses surface electromyography (sEMG) to measure the electrical activity produced by targeted muscle groups during therapeutic exercise.

Biofeedback helps improve a patient’s motor control and strength to regain pre-injury functionality and peak performance levels.

How mTrigger® Can Help

After an injury or surgery, most people suffer from inhibition or lack of volitional contraction (or muscle control). This can cause muscle atrophy, which can lead to muscular issues, increasing your risk of getting injured in the future. mTrigger® helps combat muscle atrophy through biofeedback to improve strength and neuromuscular control. Known as reversing inhibition via voluntary contraction, biofeedback can help awaken neuromuscular pathways and address neuromuscular issues that occur after injury or surgery.

mTrigger® improves muscle activation and learning as well as accuracy through real-time audiovisual feedback. Essentially, the tool improves the overall efficiency of therapeutic exercise and rehabilitation.

Where Can mTrigger® Be Used?

The mTrigger® biofeedback system can be used on your lower extremities, upper extremities, trunk, pelvic, and hands, as well as any muscle group accessible via sEMG.

Back pain managed

In just a few short days on the Back & Core program I saw a meaningful difference. I felt freedom from my back pain related to muscle spasms that I haven't felt in several months.

With the revamp of the app, they are constantly working to make it the best version of itself. They take ideas and suggestions seriously.

Knee pain is fading

I started using MoveU because I had nagging knee pain that bothered me when running, biking, skiing, etc. It was really bumming me out so I decided to try MoveU Knee, Ankle and Foot Program. I am about to finish week 2 and my knees already feel much better!

Comprehensive and engaging

The programs cover how to balace the whole body to minimize (or ward off any future) pain that’s caused by poor alignment. There’s an overall upbeat tone in the videos that makes you want to try your best.

Better than physical therapy

MoveU is a great program and worth the subscription. I've used it to supplement my normal weightlifting, cardio, and yoga. The monthly cost is about the same as one or two yoga classes, so it pays for itself. The app is very intuitive and well built. I'm glad to see they put in the up front work, and they are continually involved in the content. If you want to fix your issues at home, this is the best way.

To all the people that have tried every intervention. To the hopeless and helpless feeling. After all these years of disappointment with the healthcare system, there IS a solution. Dr. Mike and the Moveu Team are dedicated to get you into your healing journey. Not just the physical but also the mental - which is just as important. I love how different this program is from everything else I have ever tried. Love you guys.

Excellent Program

This is the fix for the long haul and I preach it to my family and friends. Going to a PT is great but they only work on the area your insurance allows which doesn't always fix the overall issue. Thank you Dr. Mike for creating this!

Knowledge at your fingertips

Well worth the subscription. I am a chiropractor and I refer to this program for all of my patients. For every diagnosis Dr. Mike and his crew demonstrate an appropriate stretch and/or exercise along with the progression and regression specific to their level of recovery. I highly recommend this app to anyone interested in treating musculoskeletal ailments whether it be your own or your patients. It's one of the few apps purchased that I feel I got my monies worth and more, you won't be dissapointed.

I appreciate MoveU

I have a bulging disc and I am very appreciative of this program and the knowledge I have gained on how body mechanics are all connected and what things to do to get better. I also feel the people really care about their members.

Most supportive and effective tool

This app is super easy to use. Love that I always have my videos with my on the go and the support from the coaches and community is invaluable along the way. Working through 4 herniated discs and it's the first program where I'm feeling hopeful and confident!

Great app! So much info to help you get to know your body and help you find your best alignment! Better alignment means less pain and more gain in life! MoveU has it all if you are willing to take responsibility for your own body.

It works!

I love this program, and I'm not easily impressed. They know their stuff really well and it's designed in a great way with how it progresses. The core is especially a game changer.

Get out of pain - the ultimate solution!!

I signed up for MoveU because I had this nagging pain for years with absolutely no way of fixing it because no one ever broke it down and showed me how to understand my problem. I love the short classes was well as the deeper live classes. I believe that I'm a lifer and it's one of the most important subscriptions I pay for in my life.

Your very best version just a MoveU away 🙌

All in one app, to realign and reset your whole body. In the most natural, gradual, and far from the invasive way. I have been a walking injury from sports for 30+ years...I never thought I could find an integral solution.
