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!

Part 2: The Drama Triangle

This is part two of a three-part series on self-care and preventing practitioner burnout from faculty member Jennafer Vande Vegte, MSPT, BCB-PMD, PRPC. Part One is available here. Jennafer is the co-author and co-instructor of the along with Nari Clemons, PT, PRPC.

Augh, I was so frustrated with myself. I fell for it again. Here’s the scenario: a patient came in suffering excruciating pain. She had been to see a pelvic health professional as well as various medical professionals and was unable to get relief and answers for her rectal pain. She was desperate and called me “her last hope.” Phrases used included, “I need you! Fix me! I hear you are a miracle worker! If you can’t help me no one can!” And just like that I took on the role of Rescuer.

In 1968 a psychiatrist named Stephen Karpman developed a model of personal interaction that he called the Conflict Triangle. It has also become known as the Karpman Triangle, The Drama triangle or the Victim triangle. Per Wikipedia:

The Victim: The Victim's stance is "Poor me!" The Victim feels oppressed, helpless, hopeless, powerless and ashamed. They seem unable to make decisions, solve problems, take pleasure in life or achieve insight. The Victim, if not being persecuted, will seek out a Persecutor and also a Rescuer who may save the day, but may also perpetuate the Victim's negative feelings.
The Rescuer: The Rescuer's line is "Let me help you." A classic enabler, the Rescuer feels guilty if they don't rush to the rescue. Yet their rescuing has negative effects: It keeps the Victim dependent and gives the Victim permission to fail. The rewards derived from this rescue role are that the focus is taken off of the Rescuer. When they focus their energy on someone else, it enables them to ignore their own anxiety and issues. This rescue role is also pivotal because their actual primary interest is really an avoidance of their own problems disguised as concern for the victim’s needs.
The Persecutor: (a.k.a. Villain) The Persecutor insists, "It's your fault." The Persecutor is controlling, blaming, critical, oppressive, angry, authoritative, rigid, and superior.

What is interesting about this triangle is that the roles are constantly shifting. In full rescuer mode, I gladly took on this patient, intent on solving her problems. Over time, I saw that my consistent coaching for lifestyle change and self-care was falling on deaf ears. My patient was not following through with anything I asked of her; therefore my treatment plan was not working. The patient began to get frustrated with me. I then cast myself as the victim. She became my persecutor! While perhaps in her mind, I had failed as the rescuer, she was still the victim and I had become her persecutor. At the time, I did not have the skills to know how to navigate this situation in a positive or helpful way. Finally I sought the advice of my supervisor and my therapist to draw up a contract with this patient. The contract outlined each of our responsibilities. If either of us didn’t fulfill our responsibilities, the consequence would be ending our professional relationship. When she persisted, unwilling to do her part, I discharged her per our agreement.

I learned so much from this experience. Here are some things that I have implemented and may be helpful in your practice if you have similar challenges.
- In an initial visit with a new patient I explain that the patient and I make a team and we each have a role to play in reaching the patient’s goals.
- If someone says, “Fix me!” I say, “Think of me as your coach, I can show you how to help your body heal, but it’s your job to do the work.”
- When I hear, “Everyone says you are a miracle worker.” I say, “That is so kind, but it doesn’t work that way. Healing is complicated and everyone has their own journey.”
- In this way, with baby steps, we can get OUT of the drama triangle and into healthy relationships with our patients and the people in our lives.

- Consider the Winner's Triangle published by Acey Choy in 1990.

In her blog NextMeCoaching, Jessica Vader coaches on turning Drama and Control into a Winning situation.

The three roles in the Winner’s Triangle.
Vulnerable – a victim should be encouraged to accept their vulnerability, problem solve, and be more self-aware.
Assertive – a persecutor should be encouraged to ask for what they want, be assertive, but not punishing.
Caring – a rescuer should be encouraged to show concern and be caring, but not over reach and problem solve for others.

If you struggle with professional and personal boundaries, you are not alone, and you can get support. Consider talking with your supervisor, a counselor, reading a good book on the subject, and or taking Boundaries, Mediation and Self Care, a course offering through Herman and Wallace that was designed to help pelvic health professionals stay healthy and inspired while equipping therapists with new tools to share with their patients.

We hope you will join us for Boundaries, Mediation and Self Care this November 9-11, 2019 in San Diego, CA.

Look forward to my next blog where saying no takes an unexpected turn.

The following is the first in a series on self-care and preventing practitioner burnout from faculty member Jennafer Vande Vegte, MSPT, BCB-PMD, PRPC. Jennafer is the co-author and co-instructor of the Boundaries, Self-Care, and Meditation course along with Nari Clemons, PT, PRPC.

Part 1: Boundaries

“I just want you to fix me.” How many times have we heard this statement from our patients? And how do we respond? In my former life as a “rescuer” this statement would be a personal challenge. I wanted to be the fixer, find the solution and identify the thing that no one else had seen yet. Then, if I am being completely honest, bask in the glory of being the “miracle worker” and “never giving up” on my patient.

If you recognize that this attitude was going to run me into some problems, kudos to you. If you are thinking, “well of course, isn’t that your job as a pelvic floor physical therapist?” Please read on.

On my very first job performance review, when it came time to discuss my problem areas my supervisor relayed I was “too nice” and cited some examples: giving a patient a ride home after therapy (it was raining and she would have had to wait for the bus), coming in on Saturdays to care for patients (he was sick and couldn’t make it in during the week but was making really good progress). You get the picture. At the time, I didn’t understand how this could be something I needed to work on. I was going above and beyond and I got so much satisfaction from taking care of others!

Fast forward 10 years and add to my life a husband, two daughters, a teaching job, part time homeschooling, and writing course material. I was an emotional mess. Anxiety was my permanent state of mind. I gave my best to my patients while my family got my meager emotional leftovers. Something had to change and luckily it did. I got help and learned exactly what boundaries are and how to develop as well as enforce them.

There are several resources that discuss professional boundaries in health care, like this from Nursing Made Incredibly Easy. In this particular article, health care professionals are exhorted to stay in the “zone of helpfulness” and avoid becoming under involved or over involved with patients. Health care professionals are also urged to examine their own motivation. Am I using my relationship with my patient to fulfill my own needs? Am I over involved so that I can justify my own worth?

Here are some warning signs that you are straying away from healthy boundaries with patients and becoming over involved:

• Discussing your intimate or personal issues with a patient
• Spending more time with a patient than scheduled or seeing a patient outside of work
• Taking a patient's side when there's a disagreement between the patient and his or her close relations
• Believing that you are the only health care member that can help or understand a patient

For some people, certain patients who push professional boundaries will cause the therapist to feel threatened and under activity is the result. This might result in talking badly about the patient to other staff, distancing ourselves, showing disinterest in their case, or failing to utilize best care practices for the patient.

Per Remshard 2012, “When you begin to feel a bit detached, stand back and evaluate your interactions. If you sense that boundaries are becoming blurred in any patient care situation, seek guidance from your supervisor. A sentinel question to ask is: ‘Will this intervention benefit the patient or does it satisfy some need in me?’”

Healthy professional boundaries are imperative for us and for our patients. Boundaries also help prevent burnout. Remshard delineates what healthy boundaries look like:

• Treat all patients, at all times, with dignity and respect.
• Inspire confidence in all patients by speaking, acting, and dressing professionally.
• Through your example, motivate those you work with to talk about and treat patients and their families respectfully.
• Be fair and consistent with each patient to inspire trust, amplify your professionalism, and enhance your credibility.

If you struggle with professional and personal boundaries, you are not alone and you can get support. Consider talking with your supervisor, a counselor, reading a good book on the subject or taking Boundaries, Self-Care, and Meditation, a course offering through Herman and Wallace that was designed to help pelvic health professionals stay healthy and inspired while equipping therapists with new tools to share with their patients.

We hope you will join us for Boundaries, Self-Care, and Meditation this November 9-11, 2019 in San Diego, CA.

Look forward to my next blog where The Rescuer (me) needs Rescuing and learn about the Drama Triangle.

Tiffany Ellsworth Lee MA, OTR, BCB-PMD joined the Herman & Wallace faculty to teach a course on biofeedback along with Jane Kaufman, PT, M.Ed, BCB-PMD. The month of April is Occupational Therapy month, and we are celebrating by highlighting the role that Occupational Therapists play in pelvic floor rehabilitation. Tiffany founded a biofeedback program at Central Texas Medical Center in San Marcos in 2004, and currently runs her a pelvic rehab private practice .

Working in this area of biofeedback is extremely rewarding and fulfilling to help change peoples’ lives. I have a private practice now exclusively dedicated to treating patients with pelvic floor dysfunction. I became involved in working with patients with incontinence and pelvic floor disorders because of many opportunities along my career path. I have been an Occupational Therapist since 1994. Both of my parents are also OTs, so I think I was born to do this!

Erica Vitek, MOT, OTR, BCB-PMD, PRPC wrote a blog recently about the role of OTs in pelvic health. She writes:

“As we look closer at the framework and the definition of OT (Occupational Therapy Practice Framework: Domain and Process, 3rd edition 2014), there is clear evidence that the occupational therapist (OT) has a role in the treatment of pelvic health conditions. Importantly, occupations are defined by this document as ‘…various kinds of life activities in which individuals, groups, or populations engage, including activities of daily living (ADL), instrumental activities of daily living (IADLs), rest and sleep, education, work, play, leisure, and social participation.”

The clearest examples of the OT’s role in pelvic health occupations within this section include:

1. ADL section: toileting and hygiene (continence needs, intentional control of bowel movements and urination) and sexual activity.
2. IADLs section: sleep participation (sustaining sleep without disruption, performing nighttime care of toileting needs).
3. Achieving full participation in work, play, leisure, and social activities, requires one to be able to maintain continence in a socially acceptable manner in which they can feel confident and comfortable to fulfill their roles and duties.

"We believe that the great patient need that exists can be better served by having trained OTs able to treat pelvic health conditions"

How to get started as an OT

Occupational therapists wishing to pursue pelvic floor have a few options. The first thing is to find a pelvic floor clinical setting or work with their respective settings to check to see if they can start a women's health program with a strong focus on pelvic floor. OTs quite often do not start out in pelvic health directly after school and since this is a newer area as compared to other certifications such as the NDT and PNF it takes a little bit of research, time and effort to find one’s exact niche. To get started, an OT should seek out courses that teach the basics of bladder and bowel management. It is important to understand the anatomy and physiology of the bladder, bowel, and sexual systems.

Incontinence and pelvic floor disorders have a profound impact on occupation, the daily activities that give life meaning! OTs should have a larger role in treating this patient population. Offering hope to our patients is imperative when he/she is dealing with pelvic floor dysfunction!

Keep an eye out for an upcoming post from Tiffany with some inspiring clinical case studies. You can join Tiffany and Jane Kaufman in Biofeedback for Pelvic Muscle Dysfunction to get lots of hands-on time with surface eletromyography, and to work toward BCIA certification!

The Institute has welcomed occupational therapists since our founding in 2006. In addition, three OTs: Richard Sabel, MA, MPH, OTR, GCFP, Erica Vitek, MOT, OTR, BCB-PMD, PRPC, and Tiffany Ellsworth Lee MA, OTR, BCB-PMD all teach courses as members of our faculty. (Erica Vitek is also one of several OTs who holds certification as a Pelvic Rehabilitation Practitioner through H&W).

Recently, the Institute was contacted by an Occupational Therapist who has attended many of our courses, regarding a challenge she was experiencing obtaining CEUs in her state (Oregon) for courses on Pelvic Rehab and Biofeedback. In light of this, the Institute has been discussing with some of the occupational therapists on our faculty, as well as representatives of the BCIA and Marquette University, and how to spread awareness about and recognition of OT’s roles in pelvic rehab. Below, we’ve asked faculty member Erica to share a bit more about her journey and the role of the pelvic rehab occupational therapist.

As an OT student, I had a professor who brought in practicing clinicians to discuss their unique roles out in the field. Pelvic health happened to be one of the topics of the day. I was completely intrigued by the clinician, who had such passion about the role of OT in pelvic health. It became clear that helping people with impaired basic bodily functions was imperative to fulfilling life roles and participation; it was OT. I knew from that moment that I wanted to help people deal with these challenging, private issues.

In my journey, I did not immediately start out in pelvic health, but instead in an acute care hospital that had a women’s health program with a strong interest in pelvic health. A very experienced OT and her team of 2 additional OTs were doing great work in that department already. The window of opportunity opened for me to mentor with that group and I eventually was able to begin to get my own referrals and develop a robust hospital-based outpatient practice. At that time, ALL of my experience had been with OTs doing this work and I was naïve to the fact that outside of my world, most of the clinicians doing this type of work were physical therapists (PT). I asked to join a highly trained and skilled group within my health system of all women’s health PTs. Overtime, I was able to demonstrate my level of competency within the group of PTs and contribute valuable things to our organization. Herman and Wallace Rehabilitation Institute was instrumental in my quest to demonstrate competency as they allowed OTs a clear pathway for enrollment in their coursework and application for the Pelvic Rehabilitation Practitioner Certification examination. I can be proud to have those credentials to my name.

My challenges in the area of pelvic health practice have thankfully been minimal, nearly nonexistent, and it has come to my awareness in recent weeks that this is not the case for OTs around the country trying to develop themselves as pelvic health practitioners. My original OT mentors reassured me with the AOTA’s published document titled Occupational Therapy Practice Framework: Domain & Process, detailed a clear place in the role of pelvic health. This document has gone through 3 revisions over the course of its first publication in 2002. The 2nd edition was published in 2008 and the 3rd edition in 2014. I’d like to cite a few important areas of the document that I find to be helpful in an OT’s quest to demonstrate our role in pelvic health rehabilitation.

I’d first like to quote the definition occupational therapy according to the 3rd edition, “occupational therapy is defined as the therapeutic use of everyday life activities (occupations) with individuals or groups for the purpose of enhancing or enabling participation in roles, habits, and routines in home, school, workplace, community, and other settings. Occupational therapy practitioners use their knowledge of the transactional relationship among the person, his or her engagement in valuable occupations, and the context to design occupation-based intervention plans that facilitate change or growth in client factors (body functions, body structures, values, beliefs, and spirituality) and skills (motor, process, and social interaction) needed for successful participation. Occupational therapy practitioners are concerned with the end result of participation and thus enable engagement through adaptations and modifications to the environment or objects within the environment when needed. Occupational therapy services are provided for habilitation, rehabilitation, and promotion of health and wellness for clients with disability- and non-disability-related needs. These services include acquisition and preservation of occupational identity for those who have or are at risk for developing an illness, injury, disease, disorder, condition, impairment, disability, activity limitation, or participation restriction. “

As we look closer at the framework and the definition of OT, there is clear evidence that the occupational therapist (OT) has a role in the treatment of pelvic health conditions. Importantly, occupations are defined by this document as “…various kinds of life activities in which individuals, groups, or populations engage, including activities of daily living (ADL), instrumental activities of daily living (IADLs), rest and sleep, education, work, play, leisure, and social participation.” The clearest examples of the OT’s role in pelvic health occupations within this section include: 1) ADL section: toileting and hygiene (continence needs, intentional control of bowel movements and urination) and sexual activity. 2) IADLs section: sleep participation (sustaining sleep without disruption, performing nighttime care of toileting needs). 3) Achieving full participation in work, play, leisure, and social activities, requires one to be able to maintain continence in a socially acceptable manner in which they can feel confident and comfortable to fulfill their roles and duties.

Client factors as defined in this document are “Specific capacities, characteristics, or beliefs that reside within the person and that influence performance in occupations. Client factors include values, beliefs, and spirituality; body functions; and body structures.” Client factors are further identified as affecting the performance skills and participation of the clients we work with. OT’s role per definition is to “facilitate change and growth in client factors”. In order to fully enhance our client’s performance skills/participation related to change and growth in client factors, OT’s have to examine the whole person, including pelvic health impairments, which have a negative influence on performance. Within client factors, the document defines body structures as, “Anatomical parts of the body, such as organs, limbs, and their components that support body function.” Within this category, one can refer to multiple items named that relate to the care that OTs provide in pelvic health rehabilitation, including but not limited to, structures related to the digestive, metabolic, and endocrine systems and structures related to the genitourinary and reproductive systems.

Since the first email from this individual in Oregon, we have been reached by several other OTs asking about similar challenges and questions about scope of practice. Because of our commitment to honoring the AOTA’s Practice Framework, and because we believe that the great patient need that exists can be better served by having trained OTs able to treat pelvic health conditions, the Institute is working with members of our faculty and professional network to advocate for recognition of OTs in pelvic rehab and resolve confusion about scope of practice.

As someone who has spent nearly two decades marketing myself, my practice, or practices for employers, I have learned a lot of skills by trial and error. One of my favorite strategies to expand my professional network is to “Follow the Patient.” By this I mean to follow the patient to a specialist consult, to a procedure, or to a referral that you helped to coordinate. This must be done with the patient in mind, first and foremost, and then also the provider and their practice environment, so as not to have that practice shut the door on you in the future. Of course, this process can look different if you are in a health network because as an insider, you will likely be more welcome and have all the right credentials in order to simply attend a patient’s provider visit. If you are in a private practice, there are sometimes more hoops and permissions to negotiate. Following are some tips I have learned about this strategy of nurturing referral sources.

Offer the idea to the patient and see if they are open to it. It might sound like this: “If you are interested, I may be able to accompany you to your upcoming appointment. Does that interest you?” It’s very important that the patient is consenting to you being in attendance at their appointment, as the visit is for them. It may be best to not promise that you can clear your schedule, or coordinate the visit, but finding out if the patient is open to the idea is the first step.

2. Check in with the provider’s office. This can be accomplished by you or by the patient. This might sound like this: “I’d like to be sure that your provider would welcome me at your appointment. Would you prefer to contact the provider’s office or shall I?” In my experience, the provider’s office will say “if it’s ok with the patient, it’s fine with us!” Typically, a patient can bring whomever they like to an appointment, so that’s not much of an issue, unless there is close quarters or some other limiting scenario. The good thing about giving a heads up is it allows the provider’s office the opportunity to know that you may be joining your patient. I was able to follow a patient into a hernia repair surgery, and the nurses were so surprised that a physical therapist was in the prep room, they asked me “does the doctor know you are here?” in which case I was able to affirm that I indeed had permission from the surgeon.

3. When you attend the visit, allow the patient to introduce you or politely introduce yourself. Then listen. This is not the time to tell the medical provider all of the wonderful things you have been doing, or all of the things you have to offer their patients. Sometimes when reporting their history, the patient will look questioningly at me to recall details, and unless I am needed to give a brief response, I like to be quiet and stay out of the story until later. This is the time for the patient and the provider to get to know each other, establish rapport, and fewer interruptions are best.

4. Be prepared to summarize your thoughts when given the opportunity to share. Typically I have found that a medical provider will at some point turn and ask me a few questions, or simply state, “Do you have anything to add?” at which point I try to make concise yet thoughtful statements about the patient’s progress, continued challenges, and the reasoning behind the referral if I was the one to coordinate it. The summary might sound like this: “The original severe pain locations have eased, function has improved in this way, and the symptom or issue that is persisting is this. I was interested in knowing if there is potentially something else going on, or if you have a recommendation towards furthering their progress.” At this point, it’s best to not get too far ahead of yourself, or put expectations in front of the patient beyond a brief summary. In other words, don’t request specific imaging or suggest a particular procedure, as this may create an imbalance in the patient’s expectations and the reality of what takes place. If the provider wants more details or thoughts from you, they are likely to ask directly. (You can also send a progress report or summary letter prior to your visit if you have specific thoughts or concerns about what is going on.)

5. Allow the visit to unfold, listen carefully and take mental or written notes. I have often found that I recall details of anatomy, medications, or suggested interventions easily and the patient may ask about the details in a follow-up visit. This type of partnership allows the patient to have “another pair of ears” and can serve as a valuable part of the rehabilitation care planning. For example, perhaps the provider said, “Let’s try this imaging, if nothing of interest shows up, continue rehabilitation for 6 weeks. If no significant progress, I’d like to see you back here within a couple of months from today.” This allows the therapist to note that a provider visit was requested at 6 weeks following the appointment.

Marketing our services, in the long run, and especially in pelvic health, is critical in sharing awareness of the role of pelvic rehabilitation. Marketing is about relationships, and the easiest way to create a relationship is face to face. “Following” a patient along their healing journey, while it may take time out of the clinic for you, is a valuable way of engaging with providers and of being part of a collaborative process. When another provider or therapist requests that I see their patient to offer another view, I find it helpful to welcome the referring therapist to join the patient as well. This can lead to valuable discussions, sharing of information, and ultimately the patient may experience more efficient care that is directed to optimal strategies.
