Manual force, mechanically assisted articular chiropractic technique using long and/or short level contacts.

OBJECTIVE: To identify what has been theorized and/or written about the manual techniques generically classified as manual force, mechanically assisted articular chiropractic technique that utilize either short-lever contacts or a combination of short- and long-lever contacts. DATA SOURCES: A search of the Medline bibliographic database using MeSH key words (chiropractic/methods; osteopathic manipulation) was performed. The Index to Chiropractic Literature and Chiropractic Research Abstracts Collection (CRAC) were searched for the past 10 yr using the key terms of chiropractic-methods; chiropractic techniques; manipulation, chiropractic, manipulation, osteopathic, manipulation, spinal; and manipulation, joint. A hand search of textbooks was undertaken as well as review of the references included in books, monographs and collected papers. STUDY SELECTION: Studies in English were included, but it must be noted that these include publications that are not peer reviewed or refereed in any way. DATA EXTRACTION: Descriptions that discussed aspects of manipulative procedures with the characteristics were extracted by a single author. DATA SYNTHESIS: Very little was found or accessible with traditional methods of literature retrieval. Descriptions of characteristics for the attributes of techniques which use mechanical assistance to impart a force applied to specific contacts in combination with short and long levers are provided. The technique procedures which fall into this category use the mechanical assistance of specialized table parts, including drop sections and distracting sections, to achieve functional changes in the vertebral three-joint complex. Conjecture and speculation as to the advantages of mechanical assistance are presented. CONCLUSIONS: This type of review is considered the first step in the evaluative process for a chiropractic technique procedure. It demonstrates that very little has been written in an accessible fashion relative to techniques which are classified as manual force, mechanically assisted articular chiropractic techniques that utilize either short-lever contacts or a combination of short- and long-lever contacts. Controlled prospective clinical trials to evaluate efficacy in using these technique procedures are nonexistent. Furthermore, there are no comparison studies to determine whether the techniques which fit into this category are any more effective or efficient in producing a positive clinical outcome than techniques in other categories. The proponents of these technique procedures should be performing the studies and publishing the results that either support or deny the usefulness of these procedures.

State of the art in standardized patient programs: a survey of osteopathic medical schools.

In 2001, the authors sent a survey to all 19 schools of osteopathic medicine requesting information about how standardized patients are used for clinical teaching and skills assessment. The purpose of this survey was to identify key people involved in standardized patient programs (SPPs), to gather information on the resources allocated by osteopathic medical schools, to determine the "state of the art" of standardized patient teaching and assessment in osteopathic medical schools, and to assess which SPPs would be available to assist in the development of the new component of the National Board of Osteopathic Medical Examiners licensing examination, the Comprehensive Osteopathic Medical Licensing Examination Performance Evaluation. The survey results revealed that 12 osteopathic medical schools have SPPs that teach and assess clinical skills, including history taking; physical examination (complete and focused); genital, rectal, and breast examinations; physician-patient communication, osteopathic manipulative medicine or osteopathic manipulative treatment. Details of the 12 schools' SPPs are highlighted.

Update on osteopathic medical concepts and the lymphatic system.

The osteopathic medical profession has long recognized the importance of the lymphatic system in maintaining health. A review of scientific studies shows much information on the mechanisms and importance of lymph circulation. Many osteopathic manipulative techniques designed to treat patients with tissue congestion are based on early research recognizing that lymph flow is influenced by myofascial compression. Osteopathic manipulative treatment of the diaphragm was substantiated when pressure differentials created by the thoracic diaphragm were shown to influence lymph flow. Current research demonstrates that autonomically mediated, intrinsic lymphatic contractility plays a significant role in lymph propulsion, supporting the use of osteopathic manipulative techniques directed at influencing the autonomic nervous system to improve lymphatic circulation. Although research provides an explanation of how osteopathic manipulative techniques influence the lymphatic system, experimentation to test the direct influence of manipulation on lymph circulation is needed. Clinical outcomes studies are also necessary to substantiate the clinical efficacy of osteopathic manipulative techniques.

The muscle hypothesis: a model of chronic heart failure appropriate for osteopathic medicine.

Chronic heart failure is one of the most serious medical problems in the United States, affecting some 4 million persons. In spite of its common occurrence, and comprehensive literature regarding this condition, no unifying hypothesis has been accepted to explain the signs and symptoms of chronic heart failure. The cardiocirculatory and neurohormonal models place an emphasis on left ventricular ejection fraction and cardiac output and do not provide appropriate explanations for the symptoms of breathlessness and fatigue. The muscle hypothesis supplements these conventional models. It proposes that abnormal skeletal muscle in heart failure results in activation of muscle ergoreceptors, leading to an increase in ventilation and sensation of breathlessness, the perception of fatigue, and sympathetic activation. At least one fourth of patients with chronic heart failure are limited by skeletal muscle abnormalities rather than cardiac output. Cardiac rehabilitation exercise can lead to an increase in exercise capacity that is superior to that gained from digitalis or angiotensin-converting enzyme inhibitors. Exercise tends to reverse the skeletal muscle myopathy of chronic heart failure and reduces the abnormal ergoreflex. Other interventions that have been shown to have a favorable outcome include localized muscle group training, respiratory muscle training, and dietary approaches. The possibility that osteopathic manipulative treatment might be of benefit is an attractive, but untested, possibility.

The effect of cranial manipulation on the Traube-Hering-Mayer oscillation as measured by laser-Doppler flowmetry.

CONTEXT: A correlation has been established between the Traube-Hering-Mayer oscillation in blood-flow velocity, measured by laser-Doppler flowmetry, and the cranial rhythmic impulse. OBJECTIVE: To determine the effect of cranial manipulation on the Traube-Hering-Mayer oscillation. DESIGN: Of 23 participants, 13 received a sham treatment and 10 received cranial manipulation. SETTING: Osteopathic Manipulative Medicine Department, Midwestern University, Downers Grove, Ill. PARTICIPANTS: Healthy adult subjects of both sexes participated (N = 23). INTERVENTION: A laser-Dopper flowmetry probe was placed on the left earlobe of each subject to obtain a 5-min baseline blood-flow velocity record. Cranial manipulation, consisting of equilibration of the global cranial motion pattern and the craniocervical junction, was then applied for 10 to 20 min; the sham treatment was palpation only. MAIN OUTCOME MEASURE: Immediately following the procedures, a 5-min posttreatment laser-Doppler recording was acquired. For each cranial treatment subject, the 4 major components of the blood-flow velocity record, the thermal (Mayer) signal, the baro (Traube-Hering) signal, the respiratory signal, and the cardiac signal, were analyzed, and the pretreatment and posttreatment data were compared. RESULTS: The 10 participants who received cranial treatment showed a thermal signal power decrease from 47.79 dB to 38.49 dB (P < .001) and the baro signal increased from 47.40dB to 51.30 dB (P < .021), while the respiratory and cardiac signals did not change significantly (P > .05 for both). CONCLUSION: Cranial manipulation affects the blood-flow velocity oscillation in its low-frequency Traube-Hering-Mayer components. Because these low-frequency oscillations are mediated through parasympathetic and sympathetic activity, it is concluded that cranial manipulation affects the autonomic nervous system.

Osteopathic approach to sexual dysfunction: holistic care to improve patient satisfaction and prevent mortality and morbidity.

Erectile dysfunction has multiple causes; most commonly the causes are mixed, a combination of physical and physiologic dysfunction. Two hypothetical case presentations provide the context for a discussion of the neurologic basis of erectile dysfunction and sexual dysfunction from the perspective of osteopathic medicine's holistic approach. Both offer osteopathic physicians the challenge of correcting structural, biological, and chemical defects to restore normal function. One of the cases is representative of patients who do not tell their physicians about sexual dysfunction unless their physicians specifically ask, and even then, these patients are most likely to lie to protect their self-esteem. The second hypothetical patient is representative of those patients who consult their physicians for any reason other than sexual dysfunction, expecting their physicians to figure out the real problem. Both of the hypothetical patients require not only support, but also education and counseling to motivate them to adopt healthier lifestyles and choices. Both would benefit from osteopathic manipulative treatment to correct structural abnormalities, and an oral medication such as a phosphodiesterase type 5 inhibitor offers both patients a good and easily accepted treatment option for erectile dysfunction.

An osteopathic approach to treating women with chronic pelvic pain.

Chronic pelvic pain is a common gynecologic complaint, affecting about 5% of American women. The differential diagnosis is broad, including many medical diseases, surgical indications, musculoskeletal problems, and somatic dysfunction. Women are more affected than men by pelvic pain because their bodies are subject to more changes. These changes include a cyclic hormonal milieu, major alterations in biomechanics during pregnancy, psychosocial stress, and other modifications during childrearing, and more adjustments during menopause. Both medical and surgical approaches to management exist, but integrative modes of therapy address the body-mind-spirit continuum. Osteopathic manipulative treatment is a valuable option for many affected women from childbirth to menopause.

Increased lymphatic flow in the thoracic duct during manipulative intervention.

The thoracic pump and the abdominal pump are osteopathic manipulative (OM) lymphatic pump techniques frequently used by osteopathic physicians to treat patients with infections (eg, pneumonia, otitis media). Although there is a widely accepted belief among the osteopathic medical profession that increasing lymphatic flow is beneficial, no measurements of lymph flow during osteopathic manipulative treatment have been reported. The authors surgically instrumented five mongrel dogs to record lymphatic flow in the thoracic duct (TDF) and cardiac variables during three intervention protocols. After recovery from surgery, canine subjects were placed in a standing-support sling, and TDF, cardiac output, mean aortic blood pressure, and heart rate were recorded during two randomized 30-second sessions of manipulative intervention using the osteopathic thoracic pump and abdominal pump techniques on two successive days. Lymph flow in the thoracic duct increased from 1.57+/-0.20 mL x min(-1) to a peak TDF of 4.80+/-1.73 mL x min(-1) during abdominal pump, and from 1.20+/-0.41 mL x min(-1) to 3.45+/-1.61 mL x min(-1) during thoracic pump. Lymph flow in the thoracic duct and cardiac variables were also recorded for canine subjects during physical activity (ie, treadmill exercise at 3 miles per hour at 0% incline). During physical activity, TDF increased from 1.47+/-0.33 mL x min(-1) to 5.81+/-1.30 mL x min(-1). Although cardiac variables did not change significantly during manipulative intervention with lymphatic pump techniques, cardiac output and heart rate did increase during physical activity. The authors conclude that physical activity and manipulative intervention using thoracic pump and abdominal pump techniques produced net increases in TDF (P<.05).

Single-blind randomised controlled trial of chemonucleolysis and manipulation in the treatment of symptomatic lumbar disc herniation.

This single-blind randomised clinical trial compared osteopathic manipulative treatment with chemonucleolysis (used as a control of known efficacy) for symptomatic lumbar disc herniation. Forty patients with sciatica due to this diagnosis (confirmed by imaging) were treated either by chemonucleolysis or manipulation. Outcomes (leg pain, back pain and self-reported disability) were measured at 2 weeks, 6 weeks and 12 months. The mean values for all outcomes improved in both groups. By 12 months, there was no statistically significant difference in outcome between the treatments, but manipulation produced a statistically significant greater improvement for back pain and disability in the first few weeks. A similar number from both groups required additional orthopaedic intervention; there were no serious complications. Crude cost analysis suggested an overall financial advantage from manipulation. Because osteopathic manipulation produced a 12-month outcome that was equivalent to chemonucleolysis, it can be considered as an option for the treatment of symptomatic lumbar disc herniation, at least in the absence of clear indications for surgery. Further study into the value of manipulation at a more acute stage is warranted.

Professional identification and affiliation of the 1992 graduate class of the colleges of osteopathic medicine.

This survey of the 1992 graduates of colleges of osteopathic medicine included questions regarding their identification with the osteopathic medical profession from application to medical school through residency training and practice. Findings of the study demonstrate that a large majority of graduates regard the profession positively. However, many express concerns about the limited training in advanced osteopathic manipulative skills, with several indicating a low level of confidence in integrating osteopathic techniques into clinical practice. Study respondents also assert that the osteopathic medical profession has yet to effectively project and promote its distinctiveness to the general public. These factors affect the overall identification and affiliation of the respondents to the osteopathic medical profession. Previous anecdotal and research reports suggested that a migration of graduates into nonosteopathic postgraduate training programs and the de-emphasis of osteopathic manipulative medicine in clinical training sites have created an identity crisis within the profession. These reports stimulated the undertaking of this study. Challenges to the profession addressed in this paper include: (1) requiring advanced training in osteopathic manipulative medicine after the second year of medical school; (2) creating an awareness of the need for increased professional visibility; (3) producing effective public relations strategies to portray the osteopathic medical profession accurately; and (4) generating sufficient funds to carry out these strategies.

Review of integrated neuromusculoskeletal release and the novel application of a segmental anterior/posterior approach in the thoracic, lumbar, and sacral regions.

Integrated neuromusculoskeletal release (INR) using a segmental anterior/posterior approach is an osteopathic manipulative treatment technique that is easily learned and applied. The segmental anterior/posterior approach to INR was developed as a practical osteopathic manipulative treatment procedure for the inpatient setting, but also has equal efficacy in the outpatient setting. It builds on the principles of INR and myofascial release techniques, as well as other techniques. This approach focuses on both the anterior and posterior connectivity of the body through the neuromusculoskeletal system and uses this connectivity to effectively treat somatic dysfunctions. The principles of INR are discussed, as well as the role of INR in the diagnosis and treatment of somatic dysfunctions in the thoracic, lumbar, and sacral regions.

Perceptions of philosophic and practice differences between US osteopathic physicians and their allopathic counterparts.

Data were gathered through a random national mail survey of 3000 US osteopathic physicians. Nine hundred and fifty-five questionnaires were usable for analysis. Through open-ended questions, osteopathic physicians identified philosophic and practice differences that distinguished them from their allopathic counterparts, and whether they believed the use of osteopathic manipulative treatment (OMT), a key identifiable feature of the osteopathic profession, was appropriate in their specialty. Seventy-five percent of the respondents to the question regarding philosophic differences answered positively, and 41 percent of the follow-up responses indicated that holistic medicine was the most distinguishing characteristic of their profession. In response to the question on practice differences, 59 percent of the respondents believed they practiced differently from allopathic physicians, and 72 percent of the follow-up responses indicated that the osteopathic approach to treatment was a primary distinguishing feature, mainly incorporating the application of OMT, a caring doctor-patient relationship, and a hands-on style. More respondents who specialized in osteopathic manipulative medicine and family practice perceived differences between them and their allopathic counterparts than did other practitioners. Almost all respondents believed OMT was an efficacious treatment, but 19 percent of all respondents felt use of OMT was inappropriate in their specialty. Thirty-one percent of the pediatricians and 38 percent of the non-primary care specialists shared this view. Eighty-eight percent of the respondents had a self-identification as osteopathic physicians, but less than half felt their patients identified them as such. When responses are considered in the context of all survey respondents (versus only those who provided open-ended responses) not a single philosophic concept or resultant practice behavior had concurrence from more than a third of the respondents as distinguishing osteopathic from allopathic medicine. Rank and file osteopathic practitioners seem to be struggling for a legitimate professional identification. The outcome of this struggle is bound to have an impact on health care delivery in the US.

Gross range of motion in the cervical spine: the effects of osteopathic muscle energy technique in asymptomatic subjects.

Muscle energy technique is an established osteopathic manipulative intervention often used to treat somatic dysfunctions of the spine. There are little objective data to demonstrate its efficacy, however. To determine the efficacy of this osteopathic manipulative technique, the authors compared active cervical range of motion among asymptomatic young and middle-aged adults (n=18) before and after this treatment protocol, comparing those results against matched control subjects (n=14) who received sham manipulative treatment. Range of motion was measured in three planes (flexion/extension, lateral bending, rotation) on all subjects (N=32) using a motion-analysis system. Multiplanar gross cervical motion restrictions were diagnosed in this asymptomatic population. In the treatment group, cervical long restrictor muscles were treated with the muscle energy technique in the sagittal, frontal, and horizontal planes. The control group had relative restrictions addressed by means of a sham manipulative treatment protocol in which the barriers to motion were not challenged therapeutically. The muscle energy technique produced a significant increase in overall regional cervical range of motion in the treatment group (approximately 4 degrees) when compared with control subjects (P<.001). Significant differences were also observed in the magnitude of change in the three planes of movement (rotation, P<.002; lateral bending, P<.01), with flexion/extension being the least affected (P=.2). These data demonstrate that the application of the muscle energy technique can produce acute increases in the active cervical range of motion in asymptomatic subjects.

Efficacy of high-velocity low-amplitude manipulative technique in subjects with low-back pain during menstrual cramping.

Previous studies have shown that dysmenorrhea produces low-back pain and an electromyographic (EMG) pattern typical of trauma-induced low-back pain. To determine the effects of high-velocity low-amplitude osteopathic manipulative treatment (OMT) on this type of low-back pain, 12 dysmenorrheic subjects were assigned to a group receiving OMT or to a group not receiving OMT (or both). Eight subjects participated in both groups, the other four being equally distributed between groups. Osteopathic manipulative treatment significantly decreased EMG activity during extension of the lumbar spinae erector muscles and abolished the spontaneous EMG activity. These EMG changes coincided with the patient's report of alleviated low-back pain and menstrual cramping. Osteopathic manipulative treatment did not change the creatinine kinase, lactate dehydrogenase or lactate-dehydrogenase isoenzyme activity, or myoglobin concentration.

A comparison of osteopathic spinal manipulation with standard care for patients with low back pain.

BACKGROUND: The effect of osteopathic manual therapy (i.e., spinal manipulation) in patients with chronic and subchronic back pain is largely unknown, and its use in such patients is controversial. Nevertheless, manual therapy is a frequently used method of treatment in this group of patients. METHODS: We performed a randomized, controlled trial that involved patients who had had back pain for at least three weeks but less than six months. We screened 1193 patients; 178 were found to be eligible and were randomly assigned to treatment groups; 23 of these patients subsequently dropped out of the study. The patients were treated either with one or more standard medical therapies (72 patients) or with osteopathic manual therapy (83 patients). We used a variety of outcome measures, including scores on the Roland-Morris and Oswestry questionnaires, a visual-analogue pain scale, and measurements of range of motion and straight-leg raising, to assess the results of treatment over a 12-week period. RESULTS: Patients in both groups improved during the 12 weeks. There was no statistically significant difference between the two groups in any of the primary outcome measures. The osteopathic-treatment group required significantly less medication (analgesics, antiinflammatory agents, and muscle relaxants) (P< 0.001) and used less physical therapy (0.2 percent vs. 2.6 percent, P<0.05). More than 90 percent of the patients in both groups were satisfied with their care. CONCLUSIONS: Osteopathic manual care and standard medical care had similar clinical results in patients with subacute low back pain. However, the use of medication was greater with standard care.

National study of the impact of managed care on osteopathic physicians.

The study reported here was designed to provide insight into the impact managed care has had on osteopathic physicians' ability to practice medicine, as well as data to substantiate the prevalence of the specific problems encountered by the 40,000 osteopathic physicians in the United States. New data on the extent to which osteopathic physicians use osteopathic manipulative treatment was also obtained, as a review of the literature revealed only two previous surveys on the use of osteopathic manipulative treatment. The American Osteopathic Association hired an independent research company to conduct the survey.

Osteopathic evaluation and manipulative treatment in reducing the morbidity of otitis media: a pilot study.

OBJECTIVE: To study the effects of osteopathic manipulative treatment in routine pediatric care for children with recurrent acute otitis media. STUDY DESIGN: Pilot cohort study with 1-year posttreatment follow-up. At follow-up, subjects' parents or legal guardians and their referring and/or family physicians were contacted to determine recurrence of otitis media since intervention. SUBJECTS: A referred and volunteer sample of pediatric patients ranging in age from 7 months to 35 months with a history of recurrent otitis media (N=8). INTERVENTION: For 3 weeks, all subjects received weekly osteopathic structural examinations and osteopathic manipulative treatment. This intervention was performed concurrently with traditional medical management. RESULTS: Five (62.5%) subjects had no recurrence of symptoms. Of the three remaining subjects in this cohort, one had a bulging tympanic membrane, another had four episodes of otitis media, and the last underwent surgery after recurrence at 6 weeks posttreatment. Closer analysis of the posttreatment course of the last two subjects indicates that there may have been a clinically significant decrease in morbidity for a period of time after intervention. CONCLUSION: The present study indicates that osteopathic manipulative treatment may change the progression of recurrent otitis media, a finding that supports the need for additional research in this area.

Making a difference: the osteopathic approach lecture series.

The Osteopathic Approach Lecture Series (Osteopathic AppLeS) was created in response to both the current need in the osteopathic medical profession for a distinctive osteopathic identity and lack of readily available information regarding an osteopathic approach. The series consisted of 16 lectures given to interns, externs, residents, and attendings at a community-based osteopathic hospital during a 10-month time span which emphasized and inculcated an osteopathic approach to patients with a variety of illnesses. Emphasis was placed on osteopathic manipulative treatment training throughout the series. Data were collected at individual presentations using a survey of participants and studied retrospectively. The results of the surveys indicated that using this type of presentation series may substantially increase confidence and knowledge in an osteopathic approach and osteopathic manipulative treatment skills.
