Surface EMG is the only modality that can isolate the active component of tone and is, therefore, a very valuable tool in the assessment of patients with altered tone conditions. However, it is the most misunderstood modality in pelvic health therapy. Rarely do practitioners see a topic so argued in pelvic rehabilitation as surface EMG biofeedback. Some practitioners boldly state they are for or against it on their social media accounts and clinic pages. Therapists are not questioning the use of biofeedback with neurologic or orthopedic applications, so why is it such a polarizing topic in pelvic health? The Pelvic Rehab Report sits down with faculty members Tiffany Lee and Jane Kaufman to discuss the tool they love. These two instructors have over 50 years of combined experience using biofeedback and have been teaching biofeedback board certification courses together for the past 16 years.
Biofeedback provides visual and auditory feedback of muscle activity and is a non-invasive technique that allows patients to adjust muscle function, strength, and behaviors to improve pelvic floor function. The small electrical signal (EMG) provides information about an unconscious process and is presented visually on a computer screen, giving the patient immediate knowledge of muscle function and enabling the patient to learn how to alter the physiological process through verbal and visual cues. Jane Kaufman explains “Many patients gain knowledge and awareness of the pelvic floor muscle through tactile feedback, but the visual representation helps patients hone in on body awareness and connect all the dots." Muscle evaluation through digital exam offers strength but does not appropriately address electrical activity such as resting tone and the ability to recruit or release tone in the muscle. The use of biofeedback addresses the specificity of muscle contraction and release, offering an additional view of muscle function.
In a 2020 research study by Pilkar et al., clinicians reported sEMG barriers of use, which included limited time and resources, clinically inapplicable sEMG system features, and the majority of clinicians' lack of training and/or confidence in the utilization of sEMG technology. This research also noted technical challenges, including the limited transfer of ever-evolving sEMG research into off-the-shelf EMG systems, nonuser-friendly intuitive interfaces, and the need for a multidisciplinary approach to accurately handling and interpreting data.
One barrier may be the price of a biofeedback unit. Tiffany Lee recommends using a 2-channel sEMG biofeedback hand-held unit with the software on a laptop or computer. In fact, to become board-certified in pelvic floor biofeedback, the Biofeedback Certification International Alliance (BCIA) requires a 2-channel EMG system with software. If you use a hand-held one-channel unit, the patient will have difficulty seeing the muscle activity and the coordination between the abdominals and pelvic floor. This prevents meaningful treatment as the patient cannot understand or interpret the LED bars on the machine (and often, the therapist cannot understand either). In truth, the benefits outweigh the cost of the equipment. You can cover the unit's cost and software to visualize muscle function and tone within a few treatments. Training is another issue; you need proper training in the modality to start utilizing biofeedback in your clinical setting. Most therapists have never been adequately trained. If they take a course where the instructor doesn’t believe in the benefits of biofeedback, they feel negatively toward a modality they have never personally explored. Biofeedback relies on a skilled clinician to interact with the patient, give verbal cues, ensure that the proper muscles are contracting and relaxing, and must be used in conjunction with their other skills and knowledge.
Think of sEMG biofeedback as one tool in your toolbox. Tiffany shares, "In a study by Aysun Ozlu MD et al., the authors conclude that biofeedback-assisted pelvic floor muscle training, in addition to a home exercise program, improves stress urinary incontinence rates more than a home exercise program alone." She continues, "Biofeedback is a powerful tool that can benefit your patient population and add to your skill set.
The acceptance of sEMG biofeedback in rehabilitation requires a unit (with software and sensors), training, and a multidisciplinary approach. Used correctly, it can positively impact patient performance and care in the clinic. Keep in mind that sEMG is a non-invasive technique. It has already shown great promise in neurorehabilitation and has been a widely utilized tool to assess neuromuscular outcomes in research. Jane Kaufman concludes, "Biofeedback treatment/training using the proper instrumentation provides the precise information necessary to change behaviors." This allows the patient to recognize that ‘yes, they are in charge of this muscle and that they can achieve success in overpowering the symptoms.’ Biofeedback routinely allows patients to understand that they are empowered to heal themselves with the tools you offer. They are in charge of their bodies and the outcome of treatment. It is also an important tool to use with patients who have experienced trauma and who are not ready to participate in manual therapy, and it is valuable for the pediatric population as well. Tiffany adds, “This modality can bring new business to your clinic. My local GI and colorectal providers often refer up to 5 new patients a week to my practice.
There is a long history of scientific evidence supporting the use of sEMG biofeedback in managing incontinence or pain symptoms. As a noninvasive, cost-effective, and powerful treatment modality, healthcare providers should consider this tool when managing pelvic floor dysfunction patients. Providers should be educated in the proper use of this valuable modality to gain the most out of the skills and knowledge that can be achieved through this intervention.

Tiffany asked several PTs and OTs who have been to the board certification courses what they love about biofeedback. Here are a few answers
- “Biofeedback empowers my patients and gives them the confidence that they are actually doing their exercises and relaxing correctly! I’ve had nothing but positive feedback from patients, and it’s such a great tool to have as a pelvic floor therapist.”
- “My patients really love it, and they ask for it. I especially see the value for dyssynergia work on bearing down and learning eccentric abdominals and relaxed pelvic floor muscles. For men, I work on relaxing in standing and toileting postures if they can’t empty their bladder.”
- “Ultimately, the treatment needs to be meaningful to the patient. Biofeedback can complement other treatments. Their needs come before ours. We should offer all of our patients the ability to control their own muscles and SEE how to do it.”
- “After ONE session with a 5-year-old with constipation, mom called me in sheer excitement, screaming over the phone that he pooped on the potty!!! Something he has NEVER done before. Biofeedback helped him find and coordinate the potty muscles and tummy muscles, and this made a huge difference for him!”
- “Becoming certified in biofeedback has only been positive for me. My patients feel that the initial sEMG evaluation sets the stage for my care plan, and my discharge reassessment is a tangible reflection of their progress. Not to mention its strength as a marketing tool.”
Jane Kaufman adds “Biofeedback in treatment has been a game changer. Using this tool as a foundation for treatment in my clinic allowed my practice to grow, thrive, and achieve great acclaim in our region and beyond. It is not unusual for patients to travel several hours to seek treatment because of the empowering effect the biofeedback visual had on their understanding of their dysfunction.”
Biofeedback for Pelvic Floor Muscle Dysfunction is scheduled for July 28th and December 7th, 2024, and provides a safe space for clinicians to learn and practice this valuable tool. Registrants will need equipment to participate in this online course and will learn about the benefits of using this modality in their clinical practice.
In this course, Tiffany and Jane guide participants through learning to administer biofeedback assessments, analyze and interpret sEMG signals, conduct treatment sessions, and role-play patient instruction/education for each diagnosis presented during the many hands-on lab experiences.
