Can lymphedema be prevented following breast cancer surgery?

Research led by Mei Fu, associate professor of Chronic Disease Management at New York College of Nursing, offers support for a preventive approach to lymphedema following breast cancer treatment. 140 women who were followed for 12 months were included in the study and outcomes included limb volume measurement from baseline (prior to surgery 2-4 weeks post-surgery, and at 6 and 12 months. Lymphedema was defined in the study as a 10% or greater increase in limb volume. 134 women completed the study, with 97% maintaining limb volume.

Of the subjects studied, axillary lymph node dissection was completed in almost 60%, and approximately 40% had sentinel lymph node biopsy. The self-care strategies in the research included shoulder mobility exercises, muscle-tightening deep breathing, muscle-tightening pumping exercises, and large muscle group exercise such as walking, swimming, yoga) to promote lymph health. The participants were also instructed in nutritional information aimed toward maintaining body mass index (BMI.) 97% of the women were also able to maintain BMI at the 12 month follow-up.

The majority of women in this pilot study also reported that the educational program helped in understanding of risk reduction for lymphedema, and also reduced their fear and anxiety about the condition. This type of research is very encouraging towards empowering patients following breast cancer. The authors note that a larger study population in a randomized, controlled trial will offer further information to guide clinical program development. While this study focused on participants with a diagnosis of breast cancer, is it likely that similar lifestyle and activity education would offer prevention of abdominopelvic and lower extremity lymphedema?

Within the Institute's Oncology series, you can learn more about these topics at several continuing education courses. To learn more about lymphedema, check out the Rehab for the Breast Oncology Patient, or the Oncology and the Pelvic Floor Courses (divided into male and female topics.)

Postpartum Lower Extremity Nerve Injuries

Research by Wong and colleagues published by the American College of Obstetricians and Gynecologists reported on the incidence of postpartum lumbosacral and lower extremity injuries. Of 6048 women who were interviewed, 56 had a new injury, confirmed by physiatrist evaluation. The researchers noted that "Women with nerve injury spend more time pushing in the semi-Fowler-lithotomy position than women without injury." The researchers also noted that women who were nulliparous (had not given birth previously who had an assisted (forceps or vacuum) birth, or who experienced a prolonged second stage of labor, were at increased risk of nerve injury.

The most common nerves involved included the lateral femoral cutaneous nerve, followed by the femoral nerve. Radiculopathies occurred at the L4, L5, and S1 levels. The authors make the following recommendations: changing positions frequently during the pushing phase, avoiding prolonged thigh flexion, avoiding extreme thigh abduction and external rotation. Other labor-related perineal nerve injuries have been documented by Sahai-Srivastava et al. to occur due to prolonged squatting or to prolonged pressure from birth attendants at the knees.

The research by Wong and colleagues highlights the important of interviewing patients about past and current symptoms, birth histories including length of time spent pushing and in what positions a woman was pushing. Teaching a woman and her birth assistants about providing support to the birthing woman's body can be very helpful; a birthing woman may welcome support of a limb, yet avoiding over-compression or sustained positions without intermittent breaks may reduce risk of nerve injury. Because the authors also noted a correlation between nerve injuries and maternal pushing at higher fetal stations (the fetus had not descended as far into the birth canal they recommend attempting to shorten active pushing time by allowing the fetus to descend further prior to pushing. (This concept in itself is a very interesting topic to be followed-up on in another post!)

Why don't women seek pelvic rehab following cancer treatment?

A qualitative study based in patient interview aimed to identify the reasons that survivors of gynecologic cancer do not seek help for pelvic floor dysfunction (PFD). Interviews of 15 patients by a medical provider asked both open-ended questions and provided a list of reasons why a patient may not seek care for PFD. (These reasons were compiled by the researchers based on clinical experience and on literature reviews.) Reasons for not seeking care for PFD were separated into four categories: that the pelvic floor symptoms in comparison to cancer diagnosis seemed bearable, the specialists did not make any recommendations about the PFD, the patient did not want to go to the doctor or hospital, and the patient or provider was unaware of treatment options. Of the women included in this study, cancer diagnoses included cancer of the cervix, endometrium, and vulva, and types of pelvic floor dysfunction included urinary and/or fecal incontinence, overactive bladder, constipation, painful bladder, or obstructed voiding.

One of the primary reasons women did not seek care for PFD was lack of knowledge about potential treatments. Another frequent statement from the 15 women interviewed is that the pelvic floor symptoms, when compared to dealing with cancer, were "bearable." The authors in this research suggest that the medical community needs to consistently give attention to PFD following cancer treatment. In addition to screening for PFD, the medical community should provide "…timely referral to pelvic floor specialists."

In regards to the first category of reasons for not seeking referral, women made statements such as feeling "lucky" to only have PFD rather than the cancer, or that the PFD symptoms were not as severe as other symptoms related to cancer diagnosis and treatment. Other women reported that they had symptoms prior to cancer treatment and were "used to them." Reasons women reported for not wanting to visit the doctor or hospital included fear that the symptoms meant that the cancer had returned or that the symptoms were too embarrassing. When discussing the lack of awareness about treatment for PFD, some women assumed that the physician would have referred for treatment if therapy was warranted or needed, and others did not not know where to go for help. Some women even reported that the oncologist stated that there was no treatment available to help with symptoms of PFD.

This information begs a reaction from pelvic floor therapists everywhere. How can we best interface with both these patients and the physicians? How can we infiltrate the journals, community lectures, national conferences, and also educate our peers about available options? While women who have suffered from cancer and pelvic floor dysfunction are not unique in the lack of awareness about treatment for PFD, common treatments for cancer can create increased tissue dysfunction, fatigue, and comorbid issues such as lymph dysfunction which complicate recovery. If you would like to work more with patients who have dealt with cancer diagnoses, but have a lot of questions about how to appropriately direct treatment, the Institute has new coursework developed by Michelle Lyons, who brings her expertise to this patient population. The next opportunity to take Oncology and the Pelvic Floor A: Female Reproductive and Gynecologic Cancers is this June in Orlando.

Gestational Diabetes Screening and Follow-up

A recently published review about peripartum management of gestational diabetes mellitus (GDM) confirms that use of recommended guidelines, testing, and follow-up "…seems suboptimal at best and arbitrary at worst." Despite the fact that during pregnancy, a mother and her fetus experience health risks related to gestational diabetes, screening remains low across countries and study settings. Once a woman is diagnosed with GDM, she is at risk for developing postpartum Type II diabetes. The necessary follow-up testing is also not consistently completed, and many new mothers are challenged by recommended lifestyle modifications.

Unfortunately, women who develop gestational diabetes may not have any symptoms. Medical providers typically screen for GDM with an oral glucose tolerance test between weeks 24-28, or earlier if risk factors are present. According to Medline Plus, excessive thirst or increased urination may be present as a symptom. Blurred vision, fatigue, weight loss despite increase in appetite, frequent infections, or nausea and vomiting may also occur. A common challenge of diagnosing women with disease conditions during the peripartum period is that symptoms such as fatigue, nausea, or changes in hunger and thirst may occur as a typical part of pregnancy or the postpartum period, so a woman may not report all symptoms to her provider. Risk factors for patients in developing gestational diabetes can include age over 25, having a family history of diabetes, giving birth to a child weighing greater than nine pounds, having high blood pressure, or a high body mass index (BMI) prior to pregnancy.

What is the potential impact for pelvic rehabilitation providers who work with women during the prenatal or postpartum period? Because women who develop GDM often have larger babies, there may be an increased risk of a cesarean section, or injury to the pelvis during childbirth. While pregnant, a woman with GDM may have elevated blood pressures. In the postpartum period, the risk for developing Type II diabetes increases, yet may not develop for 5-10 years. Medical providers and patients each experience barriers to screening and follow-up, as described in the open access article available here. Barriers for health care providers can include not seeing the patient during the screening period, not having appropriate resources available for testing, lack of coordination between different providers, and patient refusal of the test. Even if a woman is identified early as having gestational diabetes, and is informed about appropriate diet and exercise modifications that will reduce the risk of developing Type II diabetes in the postpartum period, poor self-efficacy and social support may limit a woman from achieving her desired goals.

As is often asked regarding review of articles in this blog, what is the role of the pelvic rehabilitation provider? If a rehab provider is aware of the risks for the condition, we can respectfully inquire if the patient has been screened, and encourage her to follow-up during the 24-28 week window as needed. If a woman complains of fatigue or blurred vision, or changes in her habits that "don't seem right" to the provider or the patient, a referral to the managing medical provider can be made. During the postpartum period, providing community education, health and wellness screening, or clinical screening can be completed. It is necessary for rehab therapists to assist in identifying barriers to exercise and proper nutrition, and coordinate with a patient's resources as able. Having a support team such as nutritionists, exercise therapists, and social services can have a positive impact, as many women are focused on the daily acts of raising a child and have too little focus on their own health.

If you are interested in learning more about the prenatal period, the postpartum recommendations for gestational diabetes, and exercise prescription, find out which of the Perinatal Series of continuing education courses fits into your schedule. (These courses do not need to be taken in any particular order. )Therapists will find a blend of evidence-based support related to peripartum issues as well as evaluation and intervention techniques to apply in the clinic.

Sacroiliac Joint Pain and the Long Dorsal Sacral Ligament

Sacroiliac Joint Pain and the Long Dorsal Sacral Ligament

SIJ

Sacroiliac joint pain can be a challenging condition to treat. One of the clinical pearls that I feel changed my practice for the better is the palpation and direct treatment of the dorsal sacral ligament. At a course many years ago, I listened to Diane Lee describing some ofAndry Vleeming's work addressing the potential role of the long dorsal sacral ligament (LDL) in pelvic pain. His valuable research was conducted in women who had complaints of peripartum pain, and it has been my experience that the information is easily extrapolated to other patient populations.

Vleeming and colleagues describe the long dorsal sacroiliac ligament anatomy as attaching to the lateral crest of the 3rd and 4th sacral segments (and sometimes to the 5th segment), and as having connections to the aponeurosis of the erector spine group, the thoracolumbar fascia, and the sacrotuberous ligament. Functionally, nutation in the sacroiliac joint will slacken the ligamentous tension in the LDL and counternutation will tension the ligament. This structure can be palpated directly caudal to the posterior superior iliac spine (PSIS).

The referenced study examined how many women had tenderness in the LDL who were also diagnosed with peripartum pelvic pain. Patients included in the study had pain in the lumbopelvic region, pain beginning with pregnancy or within 3 weeks of childbirth, were not pregnant at the time of the study, and were between the ages of 20-40. In patients with peripartum pelvic pain, 76% of the women reported tenderness in the LDL- this number increased to 86% when only patients scoring positively on the active straight leg raise test and posterior pelvic pain provocation (PPPP) test were included.

The study proposes that strain in the LDL may occur from a counternutated sacrum and/or an anterior pelvic tilt position. In my clinical experience and as instructed to many pelvic health therapists by expert clinicians such as Diane Lee, balancing the pelvic structures, activating stabilizing muscles of the inner core (pelvic floor, multifidi, transverses abdominis), and addressing soft tissue dysfunction in the ligament frequently resolve long standing localized pain in the sacroiliac joint area. The authors of the study conclude that "…knowledge of the anatomy and function of the LDL and the simple use of a pain provocation test…could be helpful in gaining a better understanding of peripartum pelvic pain." They also reported that combining tests such as the ASLR, the PPPP test, and the long dorsal sacral ligament palpation test "seems promising" in the differentiation of patients categorized as having pelvic pain versus lumbar pain.

The Value of Dialog Regarding Birth Experience

Postpartum depression is a very real, frequently occurring phenomenon that has potentially serious adverse effects on the mother, the child, and on the family as a whole. Serious consequences can include, according to McCoy et al, marital disruption, child neglect or abuse, and suicide. While there are many factors including hormonal shifts that can influence a woman in the postpartum period, strong predictive risk factors can include age less than 25, readmission to the hospital, inability to breastfeed, and lower self-reported health of the mother. A rehabilitation professional is uniquely poised to monitor a postpartum woman over an episode of care and can screen for changes in mood, behavior, or identify risk factors.

Screening for postpartum depression is often completed clinically utilizing the Edinburgh Postnatal Depression Scale. There is a shortened version, the EPDS-3, that asks about self-blame, states of anxiety, and feeling scared, and the shortened version has been documented to have excellent sensitivity. Postpartum psychosis and postpartum post-traumatic stress disorder can also negatively impact a woman's health and a provider needs to be alert for concerning symptoms.

Satisfaction with birth experience has been found to be a risk factor for developing postpartum depression. While we cannot affect a mother's birth experience after the fact, we can offer witness to her feelings, thoughts, and concerns, and we can offer support as rehabilitation professionals. What better way to learn about a patient's challenges and current sense of health than to allow a woman to share her experiences about pregnancy, labor and delivery. Inquiring in an open, non-judgmental manner about a patient's history can provide space for a patient to describe her experiences, perceptions, joys, and concerns. Having a working knowledge of the risk factors allows for therapeutic conversations and referrals in the clinical setting.

In the postpartum course, we discuss the above issues as well as how to observe, listen to, and assess a woman who may need referral for postpartum mental health screening. We also discuss the recent research shedding light on issues of depression in new fathers. The next opportunity to take Care of the Postpartum Patient is in Oakland, CA at the end of March. A great resource page on the womenshealth.gov website is the "Depression During and After Pregnancy Fact Sheet" that can be printed out and shared with patients.

Negative Consequences of Hip Dysplasia

Abnormal hip joint development causes 25-50% of all hip disease, according to an article by Goldstein and colleagues on hip dysplasia in the skeletally mature patient. An acetabulum that is dysplastic tends to be shallow and anteverted while the dysplastic femur tends to have a small femoral head and an increased neck shaft angle. These abnormalities cause increased joint contact pressures and lead to joint breakdown in the hip, and are associated with issues such as altered hip and knee biomechanics, hip instability, hip impingement, and labral or chondral dysfunction.

Developmentally, the altered joint surface contact also affects acetabular development: the well-formed contact pressure in healthy hip development helps to deepen the acetabulum. The shape and position of the acetabulum and femoral head will also influence the relative angle of the femoral neck, represented as retroversion or anteversion. Soft tissue changes occur in response to the altered bony mechanics that affect length-tension curves in the muscles and therefore affect muscle performance. Because of the primary and secondary dysfunctions that can occur with hip dysplasia, early recognition of hip dysfunction is important.

Measurements for hip position are easy to implement in the clinic and can include Craig's Test for femoral anteversion/retroversion. Treatment approaches focusing on hip abduction strengthening have been demonstrated to improve hip stability in patients with dysplastic hip. With shared structures including muscles between the hip and pelvis, pelvic rehabilitation providers must be able to assess the hip's influence on conditions of pelvic pain or other dysfunctions. To learn about detailed examination and treatment of the hip, there is still time to register for the Institute's upcoming continuing education course instructed by Ginger Garner.

Does Alcohol Cause Cancer?

A recent MedScape articlewarns that "no amount" of alcohol is safe in terms of avoiding cancer risk. Although the mechanisms between alcohol and cancer are not well understood, according to the article, alcoholic beverages can contain at least 15 ingredients that are carcinogenic, such as acetaldehyde, acrylamide, aflatoxins, arsenic, benzene, cadmium, ethanol, ethyl carbamate, formaldehyde, and lead. Potential causative mechanisms for alcohol-related cancer include that alcohol interferes with folate metabolism, and that in relation to breast cancer, alcohol can increase estrogen levels and stimulate mammary cell growth. Hard liquor can affect the oral cavity, the esophagus (especially hard liquor and the colon, rectum, and liver.

 

 

According to the author, patients who have health issues related to cancer should be warned to stop using alcohol and should be referred to cessation programs. Pregnant women and youth should be counseled not to drink at all. Alcohol consumption is recommended to be limited to 1 drink per day in women and 1.5 drinks per day for men. Alcohol screening is recommended as a "routine" part of an office visit. Whether the screening is completed on a written or electronic intake, or as part of the verbal history, patients should be asked to report the number of drinks per day, week, or month. Validated screening tools and referral resources that are helpful for patients are listed in this article written by Dr. Friedan.

 

 

Smoking in combination with alcohol can worsen the risk for detrimental health effects, especially in the oral cavity, the pharynx, larynx, and esophagus. Physical therapist intervention as a part of smoking cessation education can be an important and effective part of health management. Bladder health is also negatively impacted by smoking, as described in an earlier blog post. As physical therapists and other pelvic rehab providers become more involved in wellness education and integrate smoking and alcohol consumption into their clinical practice, increased knowledge about cancer-related lifestyle issues can be helpful. The Institute offers our Oncology series including a Female and Male focused course on cancer and the pelvic floor. The next opportunity to take Oncology and the Pelvic Floor: Female Reproductive and Gynecologic Cancers is June in Orlando.

What is Thiele's Massage?

What is Thiele's Massage?

Hip

George Thiele, MD, published several articles relating to coccyx pain as early as 1930 and into the late 1960's. His work on coccyx pain and treatment remains relevant today, and all pelvic rehabilitation providers can benefit from knowledge of his publications. Thiele's massage is a particular method of massage to the posterior pelvic floor muscles including the coccygeus. Dr. Thiele, in his article on the cause and treatment of coccygodynia in 1963, states that the levator ani and coccygeus muscles are tender and spastic, while the tip of the coccyx is not usually tender in patients who complain of tailbone pain. The same article takes the reader through an amazing literature review describing interventions for coccyx pain in the early 20th century.

Examination and physical findings, according to Dr. Thiele, include slow and careful sitting with weight often shifted to one buttock, and frequent change of position. He also describes poor sitting posture, with pressure placed upon the middle buttocks, sacrum, and tailbone. Postural dysfunction as a proposed etiology is not a new theory, and in Thiele's article he states that poor sitting posture is "…the most important traumatic factor in coccygodynia…" and even referred to postural cases as having "television disease."

In reference to treatment, Thiele suggests putting a patient in Sims' position (left lateral side lying or recumbent position), and placing the gloved index finger into the rectum with the thumb over the coccyx externally, palpating the coccyx between the thumb and index finger. The finger is then moved laterally, in contact with the soft tissues of the coccygeus, levator ani, and gluteus maximus muscles. The finger is moved with moderate pressure "…laterally, anteriorly, and then medially, describing an arc of 180 degrees until the finger tip lies just posterior to the symphysis pubis." The massaging strokes, applied to a patient's tolerance, are applied 10-15 repetitions on each side with the patient being asked to bear down during the massage strokes. Dr. Thiele recommended daily massage 5-6 days, then every other day for 7-10 days, and gradually less often until symptoms are resolved.

Thiele's massage for coccygodynia is one excellent tool in the treatment of coccyx pain. For a comprehensive view of coccyx pain, check out faculty member Lila Abatte's Coccyx Pain Evaluation and Treatment continuing education course, coming up in New Hampshire in September!

Can We Predict Who Benefits from Manual Lymph Drainage?

Can We Predict Who Benefits from Manual Lymph Drainage?

 

digestive system

An interesting study assessed the ability of fluorescence imaging to measure the benefits of manual lymphatic drainage (MLD a key component of complete decongestive therapy (CDT). Lymphatic dysfunction, often developing into lymphedema, affects a significant population of our patients who undergo treatment for breast cancer or pelvic cancer. Complete decongestive therapy includes manual lymphatic drainage, compression bandaging, therapeutic exercise, and specific skin care techniques. A theory describing the beneficial effects of MLD, as explained in this article, is that MLD stimulates a contractile or "pumping" mechanism within the superficial lymphatic system.

Although effects of MLD can be measured by limb volume assessment, this study aimed to investigate if in fact contractile function is improved. The investigators used near-infrared fluorescence, or NIR fluorescence, to measure "…the apparent propulsive lymph velocities..and…the period or time of arrival between successive propulsive events." Twelve subjects diagnosed with Grade I or II unilateral lymphedema and 10 controls were included in this research and were treated by a certified lymphedema therapist. The manual lymphatic drainage preparatory protocol for an involved upper extremity included lymphatic massage to the cervical lymph nodes x 5 minutes, then the neck, axillary region of the contralateral arm, and the ipsilateral inguinal region. Lower extremity MLD also started at the neck, then treatment was directed to the contralateral inguinal nodes and ipsilateral axillary nodes. The control subjects received massage to the neck for 3 minutes, bilateral axillary region massage x 5 minutes or bilateral inguinal regions, depending on if the upper or lower limb was imaged in the study. The appropriate limb was then treated with MLD massage techniques.

Prior to and after the treatment, images were collected that allowed the researchers to visualize the imaging contrast agent that was injected through intradermal route into the patient's upper or lower extremities. The results of the study, although limited by statistical power by the low number of subjects, demonstrated that after the manual lymph drainage, in subjects and in controls, treatment had the potential to improve lymph transport. Despite the overall evidence of potential for improvement, there were two subjects in the upper extremity lymphedema group who did not show an improved lymph transport after treatment. One of these subjects also did not respond to MLD and bandaging treatment that followed for six weeks after the fluorescence study. In the lower extremity treatment group, overall apparent lymph velocity and a decrease in the period between propulsive events was noted. The authors state that NIR fluorescence could be utilized to help predict patients who may benefit from manual lymph drainage. The imaging may also help identify functioning lymphatic vessels towards which the therapist can direct manual techniques for draining the limb effectively.

While this study was directed towards the lymphatic dysfunctions of the limbs, what does a pelvic rehabilitation therapist need to know when treating dysfunctions of lymph in the pelvis? Lymphatic function can easily be interrupted following surgeries, or radiation for pelvic cancers, or even following orthopedic injuries. Join Debora Hickman at her continuing education course Manual Lymphatic Drainage for Pelvic Pain in San Diego next month to learn technique in applying MLD for the pelvis!
