If you work with orthopedic patients, I am sure that you have had a back-pain patient that you have discharged, only for them to return a year later suffering from another episode of pain. We all know that once someone suffers from a back injury, they are more likely to develop a chronic issue. Even patients with insidious back pain and no specific injury often develop chronic issues and can have pain that waxes and wanes after the initial episode.
What happens in the body to cause this? Most of us have learned that the pelvic floor, transverse abdominus, and the deep fibers of the lumbar multifidus play an important role in stabilization. With injury, these muscles can become less effective in stabilizing the spine and pelvis. Studies have shown that muscle atrophy in the lumbar multifidus has been shown to occur with injuries and persist after resolution of the pain.1
I recently did additional research to find out other reasons that cause these local stabilizing muscles to not function optimally. I found that these muscles also can suffer from arthrogenic muscle inhibition after an episode of low back pain.2 Arthogenic inhibition is a deficit in neural activation to a muscle. It is thought to occur due to a change in the discharge of articular sensory receptors due to swelling, inflammation, joint laxity, and damage to afferent nerves.2 EMG studies have shown reduced neural activity in the deeper fibers of the multifidus in patients with back pain.3
Another thing that fascinated me was that cortical changes in the brain also occur with low back pain. Changes in cortical representation of the multifidus and the body’s ability to voluntarily activate the muscle has been noted.4 Motor retraining has been shown to reorganize the motor cortex with regards to the transverse abdominus.5 Also, improvement in brain organization and function occurs after resolution of back pain.6
This is good news for patients! As therapists, we may not be able to do anything with respects to arthogenic inhibition. However, we can work on motor retraining for the core muscles. It has been shown that specific training that targets the multifidus can restore the neural activity to the multifidus and lead to improvement of pain and function.7,8 Training the multifidus can be difficult for therapists to teach. However, studies have found that ultrasound guided biofeedback is helpful for patients to learn to contract their multifidus.9,10
Come learn more about the multifidus and how it relates to back pain and stability. In Rehabilitative Ultrasound Imaging: Women's Health and Orthopedic Topics we will go over how to help your patients learn to activate and strengthen their multifidus. Join me on February 28 - March 1st in Raleigh, NC to learn new ways to help your patients!

Ultrasound imaging is being used more frequently in the physical therapy clinical setting. Physical therapists are using ultrasound (US) imaging in varying ways. Some are using it as a training tool for the patient to learn neuromuscular control. Others are using it to guide needle placement while performing dry needling. In a recent article authored by several well-known physiotherapists, the various uses of US imaging were defined, as well as discussions regarding the scope of practice, and training for physiotherapists using ultrasound imaging.
Four uses of US imaging have been reported by physical therapists. The first and most common use of US imaging is the evaluation of muscle structure and function to aid in neuromuscular control. Essentially, the US images are being used as a source of biofeedback. This has been coined Rehabilitative Ultrasound Imaging (RUSI). Additional uses have emerged in recent years including Diagnostic US imaging which is the diagnosis and monitoring of pathology; and interventional US imaging which is using the US images to guide percutaneous procedures involving dry or wet needling. These three categories are performed during clinical care and fall under the umbrella term “point of care ultrasound.” The last category of US imaging use in physical therapy is paired with performing research.
In this article, some thoughts and areas for improvement were brought to light regarding each type of US imaging as well as the scope of practice and training for each type of US use. It was mentioned that RUSI sits almost entirely within the scope of the physical therapy profession, however, it can be difficult for therapists to receive training for this use. Therapists interested in learning diagnostic or interventional US imaging have more options for training because these uses of US have established criteria for training, competence, and regulation outlined by the World Health Organization (WHO), as well as oversight from the World Federation for Ultrasound in Medicine and Biology. These programs often are intended for other healthcare practitioners (radiologists, and sonographers), but physical therapists are able to take the courses. However, it was stated that both diagnostic and interventional US imaging do not fall within the scope of practice for a majority of physical therapists around the world. So, although training may be more available for these types of US use; therapists taking these courses gain increased experience with non-physical therapy applications, and therefore are at risk for operating outside the scope of their practice.
The authors continued with distinct recommendations for needed training for the four different types of US imaging. Several of the listed skills were fundamental knowledge that a therapist should obtain before utilizing any of the four types of US into their practice such as basic physics for US, terminology, safety, among other knowledge. Then there were skills that were specific to the particular type of US being performed. Since point-of-care use of US is generally not included as part of entry level physical therapy education programs, this knowledge needs to be obtained in a postgraduate education format. For therapists who wish to learn diagnostic application of US imaging, there are multiple courses available from schools that train sonographers. However, according to this article, the form of US imaging that sits more within the scope of practice for physical therapists, rehabilitative ultrasound imaging, does not have as many educational opportunities as diagnostic US imaging does.
Herman & Wallace offers a course that provides fundamental skills of US imaging (such as history, and knowledge of the physics needed for US imaging), as well as specific skills for real-time ultrasound imaging. The schedule of the course includes a lot of lab time with multiple US units available so the ratio of participant to US unit low. You will leave the course being able to interpret US images and use it as an assessment tool or biofeedback tool for the patient. Using RUSI will change how you treat patients! The Rehabilitative Ultrasound Imaging course is offered three more times this year. Join me in Columbia, MO this August; Madison, WI in September; or Chicago, IL in December to learn how to use this form of ultrasound imaging in your clinical practice!

Rehabilitative ultrasound imaging has been used in clinical practice for well over a decade now. It has been used for core stabilization, as well as with female incontinence patients. In recent years, transperineal ultrasound imaging has emerged as a useful tool for assessing prolapses and identifying other women’s health issues in the anterior compartment.
Like other things in men’s pelvic health, the use of ultrasound imaging for rehabilitation has lagged behind that in women’s pelvic health. Ryan Stafford is a researcher that is working to change that. In 2012, Stafford began looking at the normal responses to pelvic floor contractions and what is seen on ultrasound in men. He has since taken his research further to examine differences in men that present with post-prostatectomy incontinence. Stafford, van den Hoorn, Coughlin, and Hodges performed a study looking at the dynamic features of activation of specific pelvic floor muscles, and anatomical parameters of the urethra. The study included forty-two men who had undergone prostatectomy. Some of these men were incontinent and others remained continent. Transperineal ultrasound imaging was used to obtain images of the pelvic structures during a cough, and a sustained maximal contraction. The research team calculated displacements of pelvic floor landmarks with contraction, as well as anatomical features including urethral length, and resting position of the ano-rectal and urethra-vesical junctions.
The data was analyzed and combinations of variables that best distinguished men with and without incontinence were reported. Several important components were identified in the study. Striated urethral sphincter activation, as well as bulbocavernosus and puborectalis muscle activation were significantly different between men with and without incontinence. When these two parameters were examined together, they were able to correctly identify 88.1% of incontinent men. They further reported that poor function of the puborectalis and bulbocavernosus could be compensated for if the man had good striated urethral sphincter function. However, the puborectalis and bulbocavernosus had less potential to compensate for poor striated urethral sphincter function. This is important for a therapist that works with post prostatectomy patients to know. This can explain part of why some men improve and do so well after a prostatectomy and others don’t, even with therapy to help. If the striated urethra sphincter is damaged and its normal responses are changed during surgery, then incontinence after prostatectomy may be more likely.
Using ultrasound imaging, the therapist can examine and see exactly where a man is deficient in response; whether it is the puborectalis, or the striated urethra sphincter. It is exciting to see this new research and see how rehabilitative ultrasound imaging can influence men’s pelvic health! Come and learn how to use ultrasound imaging for your men’s pelvic health patients as well as your women’s health and back pain patients! You will see how ultrasound imaging can change your practice and how much your patients will enjoy seeing real-time images of their contractions! Thanks to our partnership with The Prometheus Group, this course includes hands-on training on the latest in pelvic ultrasound imaging.

Several weeks ago, I evaluated a patient who was referred to me from a fellow physical therapist. The patient was suffering from sacroiliac joint and low back pain. The patient is a 34-year-old nulliparous woman who is physically fit and participates in several outdoor activities. The therapist had fully evaluated the patient and did not find any articular issues within her spine or pelvis. What she did find was weakness in her local stabilizing muscles and tightness in her global stabilizing muscles. The therapist has an ample amount of clinical experience at treating low back and pelvic pain issues. She is adept at using different verbal cues, positions, and tactile cueing in order to help encourage proper activation of the local core muscles. However, the therapist knew the patient was not getting her local core muscles to fire properly. She didn’t know what else to do with this patient in order to get her to properly activate these muscles. She had tried numerous positions, verbal and tactile cueing without success.
Do you ever have patients where you feel stuck, who are not progressing as you would like them to in treatment? We all do! It is frustrating, isn’t it? The physical therapist called me and asked me to evaluate the patient using real-time ultrasound imaging. The therapist said “If the patient can just see what she is doing, she will then be able to learn how to work the muscles correctly.” She referred the patient to me so I could use ultrasound imaging within the treatment to better assess her activation strategies and use the imaging for biofeedback for with the patient. The patient was amazed with the ability to see what the different layers of muscles were doing. We found she was contracting her TA but only on her left side, and her deep multifidus was not firing at all. Using the ultrasound images, the patient was able to learn the proper way to activate her muscles. She is now working on a strengthening program for her local core muscles including her TA, pelvic floor, and multifidus. Within two treatments, the patient was able to fire her muscles in a different way and reports her back has felt better than it has in years!

I cannot emphasize enough how using ultrasound might change your practice! It not only can help you when you are stuck with a patient’s progress, but it can attract more patients to your practice. There are a lot of visual learners out there and access to visual images in therapy can influence progress and the results that are achieved. You not only can use the ultrasound to retrain the local core muscles for back and pelvic instability patients, but you can use it for incontinence patients, prolapse patients, and post prostatectomy patients as well. You can strengthen the pelvic floor without having to disrobe the patient each visit. How many men and women would appreciate that?
If you are interested in learning more about how you can use ultrasound in your practice, join me in August in New Jersey, or in November in California for Rehabilitative Ultrasound Imaging - Women's Health and Orthopedic Topics! See you there!
When a woman is given a cancer diagnosis, her entire world is turned upside down and inside out. There are so many things to think about; medical treatments, financial concerns, family concerns, and emotional upheaval. Sex may be the last thing that a woman may think about when she is actively going through treatment. However, at what rate are survivors having issues after treatment is complete?
A recent study published in the journal Cancer looked at just this. A 2-year longitudinal study was performed that tracked young adults (18-39 years old) through and after their cancer diagnosis. The most common cancers seen in the samples were leukemia, breast cancer, soft-tissue sarcoma, and non-Hodgkin lymphoma. The patients completed the Medical Outcomes Study Sexual Functioning Scale at 4 months, 6 months, and 24 months after diagnosis. At 2 years after diagnosis over 50% of the patients surveyed reported some degree of sexual dysfunction. Women that were in a committed relationship had an increased likelihood for experiencing sexual dysfunction; while men had increased rate of reporting sexual issues regardless of their relationship status.
Women that undergo cancer treatment have several reasons that could be influencing their sexual function. Fatigue is a complaint that is often expressed by cancer patients. Their body image is often altered due to surgeries that have been performed. Chemotherapy and hormonal therapy often push women into menopause which then leads to vaginal dryness. Additionally, radiation and surgical treatment can lead to scar tissue, fibrosis, and stenosis of the vagina and pelvic floor muscles.
This is where physical therapy can help! In the Pelvic Floor Series Capstone course we teach advanced techniques that help treat pelvic floor issues by working on both the muscles, and the fascia. We also cover techniques that decrease the tenderness in the muscles that then allow you to stretch the muscle with less discomfort.
All of the techniques taught in Capstone are gentle but effective. The cancer survivor is the perfect population to use these gentle techniques on! Think of how rewarding our job will be when we help relieve the pain that may be associated with intercourse, and therefore improve intimacy of a cancer survivor with her partner!
Come join us for Capstone and learn techniques that will take your treatment skills to the next level!

A couple of years ago, I wrote a blog about an interesting article by Hides and Stanton that related size and strength of the multifidus to the risk for lower extremity injury in Australian professional football players.
Now some of the same researchers are looking above. A prospective cohort study has recently been published that examined factors and their effects on concussions. Physical measurements of risk factors were taken in pre-season among Australian football players. These measurements included balance, vestibular function, and spinal control. To measure these outcomes the following tests were included: for balance the amount of sway across six test conditions were performed; vestibular function was tested with assessments of ocular-motor and vestibular ocular reflex; and for spinal control cervical joint position error, multifidus size, and contraction ability was tested. The objective measure was concussion injury obtained during the season diagnosed by the medical staff.
The findings were so interesting! Age, height, weight, and number of years playing football were not associated with concussion. Cross-sectional area of the multifidus at L5 was 10% smaller in players who went on to sustain a concussion compared to players that did not receive a concussion. There were no significant differences observed between the players that received concussion and those who did not with respect to the other physical measures that were obtained.
With all the recent evidence about the harmful effects of concussions amongst our athletes, I find this information amazing and am excited to see where the researchers take this in the future. The next question for the physical therapist is how do we train the multifidus? The multifidus can be difficult to retrain in some individuals. It is a hard muscle for some patients to learn to recruit. Biofeedback using ultrasound imaging can make this daunting task easier for many patients. With the cost of ultrasound units coming down, it is also a very reasonable tool for clinics to look at investing in.
Join me to learn more about the multifidus and how to use ultrasound imaging in the retraining process. Future course offerings include August in New Jersey, and November in San Diego. I look forward to seeing you there!

In some families, puberty is not only a time to have to deal with all the physical, hormonal, and emotional changes that are occurring, but it is a time to have to worry about and check for spinal abnormalities that can run in families. Adolescent idiopathic scoliosis is an abnormal curvature of the spine that appears in late childhood or adolescence. The spine will rotate, and a curvature will develop in an “S” shape or “C” shape. Scoliosis is the most common spinal disorder in children and adolescents. It is present in 2 to 4 percent of children between the ages of 10 and 16 years of age. There is a genetic link to developing scoliosis and scientists are working to identify the gene that leads to adolescent idiopathic scoliosis. Adolescent girls are more likely to develop more severe scoliosis. The ratio of girls to boys with small curves of 10 degrees or less is equal, however the ratio of girls to boys with a curvature of 30 degrees or greater is 10:1. Additionally, the risk of curve progression is 10 times higher in girls compared to boys. Scoliosis can cause quite a bit of pain, morbidity, and if severe enough can warrant spinal surgery.
A recent article in Pediatric Physical Therapy by Zapata et al. assessed if there were asymmetries in paraspinal muscle thickness in adolescents with and without adolescent idiopathic scoliosis. They utilized ultrasound imaging to compare muscle thickness of the deep paraspinals at T8 and the multifidus at L1 and L4. They found significant differences in muscle thickness on the concave side compared to the convex side at T8 and L1 in subjects with scoliosis. They also found significantly greater muscle thickness on the concave side at T8, L1, and L4 in patients with adolescent idiopathic scoliosis compared to controls. This is very interesting to me, and exciting to think about the possibilities of how we therapists might can use this information! My first question is, is the difference in muscle thickness a cause or result of the curvature of the spine? My next question is if we trained the multifidus on the convex side, the side that is thinner, would it make a difference in supporting the spine and therefore help prevent some of the curvature? Would strengthening the multifidus in a very segmental manner comparing right versus left and targeting segments and sides that are weaker than others help prevent rotation and curvature in individuals who have a familial predisposition to developing idiopathic scoliosis? I hope so! I hope this group continues to study scoliosis and provides some evidence-based treatment that can help decrease the severity of curvature.
Assessing the multifidus thickness and strength, and differentiating it from the paraspinal muscles can be tricky. The best way to do this is the same way the authors of this article did, using ultrasound imaging. Ultrasound imaging gives unparalleled information on muscle shape, size, and activation of the muscle. Learning to use ultrasound imaging will change your practice! You will see dramatic differences in how you treat patients as well as the results you get when training the local core musculature. It also may open doors to treating different patient types than you are treating now, like adolescents with scoliosis. Join me in Spokane, WA on October 20-22 to further discuss how ultrasound can change your practice and perhaps help you reach out to a new population that you may not be treating now!

Most of us are treating patients who have back pain of some nature, and we know the importance of the local stabilizing muscles including the transverse abdominis, the lumbar multifidus, and the pelvic floor muscles. These muscles work together to provide tension and create a corset of stability throughout the trunk. A common goal is to rehabilitate these muscles in order to restore motor control and strength, but the muscle depth can make them difficult to assess and palpate.
I recently read a study that is looking at the development of a test to identify lumbar multifidus function. Herbert et al. found promising results when looking at this “multifidus lift test” for inter-rater reliability and concurrent validity to identify dysfunction in the multifidus. They compared the results of this test with real-time ultrasound imaging of the lumbar multifidus. Inter-rater reliability was excellent and free from errors of bias and prevalence. Concurrent validity was demonstrated through its relationship with the reference standard results at L4-L5, but not so much for L5-S1. This preliminary research supports the reliability and validity of the multifidus lift test to assess lumbar multifidus function at some spinal levels. If this test could be further validated for other spinal levels it would be very beneficial for therapists who are using a specific stabilization program to treat patients.
Until this test is further developed and validated how can therapists know for sure that their patient is truly activating their multifidus? Ultrasound imaging is the answer! Ultrasound imaging gives therapists real-time feedback for whether a patient is able to correctly activate a muscle or not. It is also a wonderful biofeedback tool for patients who are trying to rehabilitate these muscles. Getting your hands on an ultrasound machine can be tough, but therapists who work in a hospital system may have an easier time than you'd think. I have worked with many therapists to help them get access to ultrasound units through “hand me down” units from imaging or labor and delivery departments. I also have helped private practice therapists set up a working relationship with a physician who has an ultrasound in their office. Thinking outside of the box can allow clinicians to gain access to ultrasound units without having to spend a lot of money. Join me in Dayton Ohio this May to hear more about how ultrasound imaging can improve your practice and allow you to incorporate a specific stabilization program into your toolbox.

The following post comes to us from Herman & Wallace faculty member Allison Ariail, PT, DPT, CLT-LANA, BCB-PMD, PRPC. Allison authored "Use of transabdominal ultrasound imaging in retraining the pelvic-floor muscles of a woman postpartum" and is a leading expert in the use of ultrasound imaging for pelvic rehab. She is the author and instructor of the Rehabilitative Ultrasound Imaging: Women’s Health and Orthopedic Topics offered with Herman & Wallace.
In the pelvic floor series we learn how to perform examinations for cystoceles and rectoceles. It can be more difficult for therapists to examine and quantify the degree of uterine descent. In the last few years translabial ultrasound imaging has also been used to identify what is happening in the anterior compartment upon Valsalva and pelvic floor contraction, including the uterus. This is helpful when trying to determine the degree of uterine prolapse. Degree of pelvic organ descent visible on by ultrasound has been shown to have a near-linear relationship with measures on the POPQ.
Clinically we see that some patients with severe prolapses have few symptoms, while other patients with smaller prolapses will have more severe complaints of symptoms. This can be puzzling to the clinician who is trying to treat prolapse patients. Shek and Dietz performed a study to set cutoff measures of uterine descent that will predict symptoms of prolapse. Translabial ultrasound imaging was performed on 538 women with 263 women reporting prolapse symptoms. Seventy-five percent of the women presented with grade two or greater prolapse on the POPQ, with most of being cystoceles or rectoceles. The women with more complaints of symptoms of prolapse were more likely to have uterine prolapse. There was a strong association between degree of uterine descent and symptoms of prolapse. They determined that an optimal cutoff to predict symptoms of prolapse due to uterine descent is a cervix descending to 15 mm above the pubic symphysis.
This study intrigues me and makes me wonder how much we are focusing on cystoceles and rectoceles and not looking at uterine prolapses. Using translabial ultrasound imaging is a nice tool to allow the clinician to see what is going on with all of the pelvic organs. With one Valsalva maneuver you are able to assess a lot of information including support of the pelvic organs. It also gives the clinician another way to quantify the degree of prolapse. Ultrasound imaging is a wonderful tool that clinicians can use for assessment as well as a biofeedback tool. If you are interested in learning how to perform this type of assessment, I will be teaching Rehabilitative Ultrasound Imaging: Women’s Health and Orthopedic Topics May 1-3 in Dayton, OH.

The following comes to us from faculty member Allison Ariail. Allison teaches several courses for the Institute, her next one being Rehabilitative Ultrasound Imaging in Baltimore, MD on June 12-14. There is still room, so sign up today!
Living in Colorado, I come across a lot of individuals who are avid runners, cyclists, or triathletes. Even with a higher level of fitness, these individuals will at times have back pain. What is going on in these physically fit, strong individuals? This is what Rostami et al. set out to determine in their recent study. Using ultrasound imaging, they measured the thickness of the transversus abdominis, internal oblique, external oblique, and the cross sectional area of the multifidus while laying down as well as while mounted on a bicycle. They also measured the back strength, endurance, and flexibility of off-road cyclists with and without back pain. Fourteen professional competitive off-road cyclists with low back pain were compared to 24 control. Results showed a significantly thinner transversus abdominis, and cross sectional area of the multifidus muscle in the cyclists with back pain. There was no significant difference found in flexibility or isometric back strength between the two groups. However the cyclists with low back pain demonstrated decreased endurance in back dynamometry with 50% of their maximum isometric back strength.
The results of this study are consistent with other studies that examined less athletic individuals; thinner transverseus abdominis, and smaller multifidus muscles. This further reinforces the training of the local stabilizing muscles. What does this training method consist of? Learning to isolate each of the local stabilizing muscles; the transversus abdominis, the multifidus, and the pelvic floor muscles. Once a patient is able to isolate a contraction, challenge the muscles by holding a contraction while breathing normally, or holding the contraction while performing motor tasks such as Sahrmann’s exercises. Progress the patient so they are able to perform contractions in weight bearing positions and co-contractions of the muscles. Finally, progress the patient to maintaining co-contractions during functional activities and exercise activities. This will improve stability of the back and pelvis as well as decrease the pain experienced by the patient.
Even patients with higher levels of activity and physical fitness can benefit from a program such as this one. I have used this treatment protocol using ultrasound imaging to confirm and train the local stabilizing muscles on individuals who are both active as well as with individuals not able to participate in as much physical activity. Each and every patient has made gains, even patients who already had a higher level of activity and sports participation such as cyclists, runners, and triathletes. It is rewarding to see all patients make gains and improvements!
