A Review of Glymphatics and the Impact of Osteopathic Manipulative Treatment in Alzheimer's Disease, Concussions, and Beyond.

Glymph is a fluid that circulates in the brain interstitium and, under pathological conditions, unusually accumulates and enhances the buildup of other noxious molecules. The study of this process of circulation, accumulation, and clearance is called glymphatics. We review the physiology of glymphatics and then dive into recent innovative research surrounding this neurological field of study and how it has applied to mainstream pathological processes, including Alzheimer's disease and spectrums of traumatic brain injury that range from a concussion to chronic traumatic encephalopathy (CTE). Furthermore, we explore the implications of glymphatics and a new and developing frontier of healthcare in space travel; with the advent of a Space Force and the introduction of space travel to consumer markets, this is an exciting time to develop novel techniques in enhancing its safety and optimizing human physiology for best outcomes. Therefore, we also propose that osteopathic manipulative treatment (OMT) plays an intuitive role in the treatment of abnormal glymphatics, as adjunctive therapy in Alzheimer's and CTE, and as a future staple before, during, and after space travel for the benefit of both enhancing healthcare in chronic conditions and advancing the capabilities of the human race in its shining new endeavor.

Effectiveness of osteopathic manipulative treatment for pediatric conditions: A systematic review

BackgroundOsteopathic manipulative treatment (OMT) is commonly used by osteopaths and osteopathic physicians to manage a large variety of pediatric complaints. ObjectiveThe current study reviewed the literature to determine the effectiveness of OMT for all pediatric complaints. MethodsA systematic literature search for randomized controlled trials (RCTs) unrestricted by language or publication status was performed in July 2020 in electronic and ongoing trials databases. Included studies were assessed using the Cochrane Risk of Bias (RoB) instrument. Mean difference or standard mean difference and overall effect size were calculated. Data were synthesized using the GRADE approach. ResultsForty-seven RCTs examining 37 pediatric conditions were reviewed. Twenty-three studies reported significant favorable outcomes for OMT relative to the control intervention, and 14 additional studies reported non-significant outcomes, which suggested potential favorable effects of OMT. Fifteen of the studies were judged to have a low RoB, 12 had high risk, and the remainder had unclear RoB. Using GRADE, there was moderate evidence for the effectiveness of OMT for 13 of the 43 comparisons, particularly for length of hospital stay for preterm infants, but no high-quality evidence for any condition. ConclusionsAlthough a number of studies indicated positive results with use of OMT, few pediatric conditions have been investigated in more than one study, which results in no high-quality evidence for any condition. Additional research may change estimates of effect, and larger, high-quality RCTs focusing on a smaller range of conditions are recommended.

The effects of gravity and compression on interstitial fluid transport in the lower limb

Edema in the limbs can arise from pathologies such as elevated capillary pressures due to failure of venous valves, elevated capillary permeability from local inflammation, and insufficient fluid clearance by the lymphatic system. The most common treatments include elevation of the limb, compression wraps and manual lymphatic drainage therapy. To better understand these clinical situations, we have developed a comprehensive model of the solid and fluid mechanics of a lower limb that includes the effects of gravity. The local fluid balance in the interstitial space includes a source from the capillaries, a sink due to lymphatic clearance, and movement through the interstitial space due to both gravity and gradients in interstitial fluid pressure (IFP). From dimensional analysis and numerical solutions of the governing equations we have identified several parameter groups that determine the essential length and time scales involved. We find that gravity can have dramatic effects on the fluid balance in the limb with the possibility that a positive feedback loop can develop that facilitates chronic edema. This process involves localized tissue swelling which increases the hydraulic conductivity, thus allowing the movement of interstitial fluid vertically throughout the limb due to gravity and causing further swelling. The presence of a compression wrap can interrupt this feedback loop. We find that only by modeling the complex interplay between the solid and fluid mechanics can we adequately investigate edema development and treatment in a gravity dependent limb.

Efficacy and Feasibility of an Osteopathic Intervention for Neurocognitive and Behavioral Symptoms Usually Associated With Fetal Alcohol Spectrum Disorder.

The purpose of this study was to evaluate the efficacy and feasibility of a 4-week planned osteopathic manipulative treatment intervention on the improvement of neurocognitive and behavioral symptoms usually associated with fetal alcohol spectrum disorder. Thirty-two symptomatic children without fetal alcohol spectrum disorder aged 3–6 years with low level of attention from two schools and an osteopathic center were recruited in a prospective randomized pilot study in an osteopathic manipulative treatment group [osteopathic manipulative treatment (OMT)] or a control group (standard support measures). Neurocognitive maturity test results for attention (A), iconic memory (IM), spatial structuration (SS), and visual perception (VP) were recorded at baseline and post-intervention. No adverse effects were communicated and there were no dropouts. A significant increase in neurocognitive assessments was observed in children in the OMT group at post-treatment. Intergroup post-intervention statistical differences were found for A, SS, and IM were p = 0.005, p < 0.001, and p < 0.001, respectively; no differences were seen for VP (p = 0.097). This study shows that a 4-week osteopathic manipulative treatment intervention may be a feasible and effective therapeutic approach for neurocognitive and behavioral symptoms usually present in fetal alcohol spectrum disorder, justifying more studies on children affected by this condition.

162 Recruiting Women Into Neurosurgery: A Quantitative Analysis of Feeder Medical School Characteristics

INTRODUCTION: Despite a recent increase in the number of women pursuing neurosurgery residency, medical school characteristics associated with the successful recruitment of female medical students into the field remain poorly studied. METHODS: A total of 1572 current residents in U.S. Accreditation-Council-for-Graduate-Medical-Education-accredited neurosurgery programs, representing match cohorts from 2014 to 2020, were evaluated. U.S. medical school characteristics such as class size and number of total and female clinical neurosurgery faculty were recorded. Medical schools were ranked based on the percentage of female graduates entering neurosurgery, and yearly trends of the percentage of females constituting incoming neurosurgery resident cohorts were studied. Associations between percent female recruitment and medical school characteristics were then evaluated using univariable and stepwise multivariable linear regression (including significant univariable factors). RESULTS: The cohort consisted of 1255 male and 317 (20%) female residents. Yearly trends indicated a significant drop in incoming female residents in 2016 followed by significant increases in 2017 and 2019. The following factors were associated with a higher average percentage of female graduates entering neurosurgery on multivariable analysis: total affiliated neurosurgery clinical faculty (β = 0.006, 95% CI [0.001-0.011], p = 0.013), allopathic vs. osteopathic schools (β = 0.231, 95% CI [0.053-0.409], p = 0.011), and top-10 U.S. News ranking (β = 0.380, 95% CI [0.129-0.589], p = 0.002). Upon adding the number of female clinical faculty to the model, the variable was not statistically significant. Multivariable bibliometric analyses indicated a higher mean pre-residency H-index for males with an even greater gender difference identified in current H-index. CONCLUSION: This study characterizes which medical schools have recruited the most female students who are currently in neurosurgery residency. The overall number of clinical neurosurgery faculty rather than faculty gender was independently associated with female recruitment. Gender differences in research productivity persisted while controlling for confounders and increased between pre-residency and current time-points.

Student Perception of an OMM Virtual Practical Examination: In the Setting of Social Distancing

Abstract Introduction: Osteopathic manipulative medicine (OMM) practical examinations (PEs) are important for assessing osteopathic medical students’ cognitive knowledge and psychomotor skills required for osteopathic manipulative treatment (OMT). In the response to the COVID-19 pandemic, first-year medical students at Des Moines University (DMU) were no longer allowed to participate in a standard in-person PE (sPE) in December 2020. A novel virtual PE (vPE) over Zoom was developed to assess the students’ understanding of OMM learned in lab to replace the sPE. Objective: To determine if the vPE was perceived by the students as a successful and efficacious alternative to the sPE. Method: After the graduating class of 2024 completed their vPE, an administrative email from the DMU OMM department was sent to gather anonymous, voluntary student feedback evaluating their perception and experience of the vPE. The survey consisted of 5 Likert scale questions that asked students to determine the extent they agree to 5 distinct statements and the survey contained a free-text response question asking for suggestions to improve the vPE experience. A Chi-square test of goodness-of-fit was used to assess for equal distributions of responses. Simultaneous 95% confidence intervals (CI) for multinomial proportions were created. The free text was qualitatively analyzed based on themes. Results: Of the 224 first-year osteopathic students, 207 students responded to the Likert scale questions and 113 responded to the free text. Students strongly agree or somewhat agree that the vPE was a fair assessment of their knowledge of OMM lab material (90.82%) and optimally assessed their procedural OMM skills (86.96%). Students strongly agree that the vPE better assessed their OMM lab knowledge than a written multiple-choice examination (73.91%) and they received helpful feedback during the vPE (77.78%). Conclusion: Survey results support that the vPE was perceived by students to be an effective and fair alternative to the sPE. The creative use of a pair of pants and a prop sacrum was validated, as students confirmed that the vPE optimally assessed their procedural skills given the practical’s limitations.

Osteopathic Approach to Treatment of Radial Head Dysfunction: The Radial Head Range of Motion Technique

Abstract Falls on an outstretched hand, overuse, and restriction of motion at the wrist can all contribute to the formation of a radial head somatic dysfunction. Radial head somatic dysfunctions may contribute to or cause painful conditions of the forearm, elbow, and wrist and impact the proper balance of muscular, neural, and circulatory influences. The radial head range of motion technique is a simple and effective osteopathic manipulative treatment (OMT) that can be utilized to address discomfort of the lateral elbow, proximal forearm, and wrist.

Patellofemoral Pain Syndrome: A Review of the Literature with Osteopathic Emphasis

Abstract Patellofemoral pain syndrome (PFPS) is a common yet complicated clinical presentation. The first objective of this paper is to review the literature related to the pathogenesis and diagnostic testing for evaluating for PFPS. The second objective is to investigate how the five models of osteopathic medicine relate to the development and treatment of PFPS. The last objective is to outline several effective osteopathic manipulative techniques that can aid in the treatment of PFPS.

Osteopathic approach to sacroiliac joint pain in pregnant patients.

This paper aims to provide a comprehensive review of the management of sacroiliac (SI) joint pain in pregnant patients. Although SI joint pain is highly prevalent among pregnant patients, the unique anatomy of the joint is rarely discussed in a clinical setting. This paper provides comprehensive review of the epidemiology, anatomy, alarm findings, standard treatment, osteopathic assessment, and osteopathic manipulative treatment (OMT) of the SI joint, and it provides a general and in-depth understanding of the SI joint pain in pregnant patients and its management.

Assessing the United States' most frequently asked questions about osteopathic medicine, osteopathic education, and osteopathic manipulative treatment.

Osteopathic medicine in the United States continues to produce a substantial number of physicians and medical educators. However, recently popularized misconceptions about osteopathic medical practice, education, and manual therapy suggest an unsettling prevalence of inaccurate beliefs held by the public. The public often searches the internet to find out information about osteopathic medicine, but the content of questions and the transparency of the resulting information is unknown. We sought to explore frequently asked questions (FAQs) generated by Google to assess commonly searched questions about the osteopathic profession and to determine the level of information transparency associated with resulting sources. On June 16, 2021, we searched Google for three terms: "osteopathic medicine," "doctor of osteopathic medicine," and "DO," until a minimum of 100 FAQs and their answer links were extracted from each search. After excluding irrelevant FAQs, we used Rothwell's Classification of Questions to categorize the FAQs. We then used the Journal of the American Medical Association's Benchmark Criteria to assess information transparency for each corresponding answer source provided by Google. The answer sources were screened for the inappropriate use of "osteopathy" in place of "osteopathic medicine" and for "osteopath" in place of "DO," "Doctor of Osteopathic Medicine," or "Osteopathic Physician." We performed statistical tests to ascertain the differences in information transparency between osteopathic and nonosteopathic information sources. Our Google search revealed 110 unique FAQs about osteopathic medicine. The majority of FAQs were classified as fact-based (82/110; 74.55%), nearly half of which (45.12%) were related to the medical practicing privileges of DOs. The FAQs were most commonly answered by academic institutions (44/110, 40.0%). Nearly half (49.09%) of the linked answer sources were deemed inadequate by JAMA benchmark criteria. Of the 110 linked answer sources, 19 (17.27%) misused either osteopathy, osteopath, or both to describe osteopathic physicians. Only 30 sources were linked to US-based osteopathic organizations. Osteopathic organizations were statistically less likely to meet high-transparency criteria than nonosteopathic organizations (p=0.002). Our study shows that the US public may be unsure about the physician status of DOs, which may prevent securing the professional identity of osteopathic physicians in the eyes of the public. Osteopathic organizations should tailor awareness campaigns toward addressing the common misconceptions revealed by our study. Osteopathic organizations should use transparency criteria as a rubric when publishing information to enhance transparency.

Inflammatory Biochemical Mediators and Their Role in Myofascial Pain and Osteopathic Manipulative Treatment: A Literature Review.

Chronic inflammatory pain conditions, specifically myofascial pain (MFP), account for an overwhelming percentage of office visits every day. The combination of the high cost of its treatment and frequent patient visits makes MFP a critical pathology to be investigated. Sharpening our understanding of the molecular mechanisms within MFP will expedite the enhancement of therapeutic approaches. Inflammation plays a critical role in the pathophysiology of MFP. The chief inflammatory mediators of interest in this review related to MFP are interleukin 1β (IL-1β), IL-6, and tumor necrosis factor-α (TNF-α). This review aimed to determine the impact of inflammatory mediators on fibroblasts and satellite cells, specifically their role in muscle injury and regeneration. Blocking pro-inflammatory mediators such as IL-1β, IL-6, and TNF-α in these cell types could prove to be an effective treatment for MFP. An osteopathic manipulative treatment (OMT) modality, specifically indirect counterstrain therapy, was investigated in the hopes of elucidating a reduction in particular cytokines. In addition, myofascial release (MFR) therapies (OMT modality) were explored as a potentially effective treatment through the acceleration of wound healing, stimulation of muscle regeneration, and decreased inflammation via altered fibroblast activity. Pharmacologic agents such as non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used to treat MFP but have a higher adverse side effect profile compared to OMT therapy. The optimal management of MFP is likely multifactorial, and more treatment modalities must be explored.This literature review analyzed 17 peer-reviewed articles specifically related to MFP management and the role of inflammation in MFP. Chronic inflammation from other etiologies was excluded. Our aim was to elucidate the biochemical mechanisms underlying MFP and inflammation in an effort to promote the medical community's understanding of treatment modalities for this chronic condition. This study revealed that various OMT techniques such as MFR and counterstrain lead to changes on the cellular level in MFP. Discovering similar effects on biochemical inflammatory markers with non-pharmacologic treatment modalities was an exciting revelation and one that could potentially change the way physicians address pain management.

Effects of osteopathic manipulative treatment vs. osteopathic cranial manipulative medicine on Parkinsonian gait.

Sixty thousand people are diagnosed with Parkinson's disease (PD) each year, making it the second most common neurodegenerative disorder. PD results in a variety of gait disturbances, including muscular rigidity and decreased range of motion (ROM), that increase the fall risk of those afflicted. Osteopathic manipulative treatment (OMT) emphasizes the central role of the musculoskeletal system, which could be ideal for addressing the somatic dysfunction associated with neurodegeneration in PD. The close anatomical relationship of structures implicated in PD within the skull and the increased frequency of strain patterns raise the question of whether osteopathic cranial manipulative medicine (OCMM) can improve gait performance by improving circulation to the affected nervous tissue. However, there have been few studies in recent years that explore the effects of a standardized OMT protocol on Parkinsonian gait characteristics, and there have been few studies that include OCMM techniques. This study aims to determine whether a single session of OMT or OMT+OCMM can improve the gait of individuals with PD by addressing joint restrictions in the sagittal plane and by increasing ROM in the lower limb. The following study is a two-group, randomized controlled trial in which individuals with PD (n=45) and age-matched healthy control participants (n=45) were recruited from the community. PD participants were included if they were otherwise healthy, able to stand and walk independently, had not received OMT or physical therapy (PT) within 30days of data collection, and had idiopathic PD in Hoehn and Yahr stages 1.0-3.0. PD participants were randomly assigned to one of three experimental treatment protocols: a 'whole-body' OMT protocol (OMT-WB), which included OMT and OCMM techniques; a 'neck-down' OMT protocol (OMT-ND), including only OMTtechniques; and a sham treatment protocol. Control participants were age-matched to a PD participant and were provided the same OMT experimental protocol. An 18-camera motion analysis system was utilized to capture 3-dimensional (3D) position data in a treadmill walking trial before and after the assigned treatment protocol. Pretreatment and posttreatment hip, knee, and ankle ROM were compared with paired t-tests, and joint angle waveforms during the gait cycle were analyzed with statistical parametric mapping (SPM), which is a type of waveform analysis. Individuals with PD had significantly reduced hip and knee extension in the stance phase compared to controls (32.9-71.2% and 32.4-56.0% of the gait cycle, respectively). Individuals with PD experienced a significant increase in total sagittal hip ROM (p=0.038) following a single session of the standardized OMT-WB treatment protocol. However, waveform analysis found no significant differences in sagittal hip, knee, or ankle angles at individual points of the gait cycle following OMT-WB, OMT-ND, or sham treatment protocols. The increase in hip ROM observed following a single session of OMT-WB suggests that OCMM in conjunction with OMT may be useful for improving gait kinematics in individuals with PD. Longitudinal studies over multiple visits are needed to determine the long-term effect of regular OMT and OMT+OCMM treatments on Parkinsonian gait characteristics.

Assessing the Knowledge of the Osteopathic Profession in New York City's Eastern European Communities.

BackgroundAccording to the decennial Osteopathic Survey of Healthcare in America, the osteopathic profession has been steadily gaining recognition in the United States, particularly among the White/Caucasian demographic. This, however, does not take into account immigrant European communities that, while racially classified as White/Caucasian, may be unexposed to osteopathic physicians (DOs) in their home country and may be reticent to osteopathic manipulative medicine. Data on non-English-speaking communities are limited and can mask the need for further outreach. This study aimed to identify literature in osteopathic outreach to minority communities and assess osteopathic awareness in New York City’s Eastern European communities. Secondary objectives include characterization of potential barriers in hindering access to osteopathic medicine, and, by extension, other minority groups.MethodologyAn anonymous survey prepared in Russian and English was used to gather demographics, education level, healthcare habits, and knowledge of the osteopathic profession. To provide a clinical scenario, a health habit question regarding low back pain (LBP) was provided to participants. Participants over the age of 18 were randomly selected from high density Eastern European areas at two separate time points. Statistical analysis was performed using R to evaluate independence between questions using chi-square tests.ResultsA total of 150 surveys met the inclusion criteria, with 71 males and 79 females, an age range of 18-92, and a median age of 62. On comparing demographics, education level, and healthcare habits, only English proficiency showed statistical significance (p = 0.039) in determining recognition of the osteopathic profession. Overall, 60% (n = 94) stated that they have heard of osteopathic medicine and knew what a DO physician does. However, only 35% (n = 53) would see a DO for LBP, with 50% (n = 77) seeing a physical therapist.ConclusionsCompared to research examining osteopathic awareness in ethnic minority communities, the Russian community in New York appears to have greater recognition of the osteopathic profession. This, however, does not translate into a clinical scenario as more participants were more likely to see a physical therapist. While this difference can be attributed to numerous factors, it stands without doubt that greater osteopathic outreach and data collection needs to be performed in minority communities.

Inhibiting the Musculoskeletal Pathological Processes in Post-knee Replacement Surgery With Osteopathic Manipulative Treatment: A Systematic Review.

Total knee arthroplasty (TKA) is a very common surgical treatment approach for severe osteoarthritis. Complications of TKA include loss of range of motion and prolonged analgesic requirement for pain control. Osteopathic manipulative techniques (OMT) have been utilized to address localized muscular stiffness to improve range of motion; however, limited studies directly correlate OMT and TKA recovery. This review highlights the therapeutic benefits OMT can have in the postoperative management of arthroplasty with respect to range of motion, edema, pain perception, and ability to perform activities of daily living. This review revealed the use of OMT would positively influence range of motion by manipulation of localized musculature and can result in decreased demand for analgesics. This can, in turn, shorten hospital stay and return the ability of patients to perform activities of daily living earlier than without OMT. Increased research is needed to strengthen these findings on the benefits of OMT in the postoperative management of arthroplasty.

Development of Osteopathic Neuromusculoskeletal Medicine (ONMM) residency curriculum guidelines to meet Accreditation Council for Graduate Medical Education (ACGME) milestones.

A memorandum of understanding was reached between the Accreditation Council for Graduate Medical Education (ACGME), the American Osteopathic Association (AOA), and the American Association of Colleges of Osteopathic Medicine (AACOM) in 2014 outlining the course for a single accreditation system for graduate medical education. This process was completed in 2020 and has included the transition of AOA-accredited neuromusculoskeletal and Osteopathic Manipulative Medicine (OMM) programs into programs now termed "Osteopathic Neuromusculoskeletal Medicine" (ONMM) under the single accreditation system. Progress through ONMM residency is evaluated on the basis of 15 ACGME milestones that encompass six core competencies. However, there are no curricular guidelines to help guide the achievement of these milestones. The primary purpose of this study was to develop a proposed structure and content for an ONMM residency curriculum that is based on (1) the alignment of residency curriculum with ACGME milestones in one ACGME-accredited ONMM residency program, and (2) the perceived needs of residents and faculty for an ONMM residency curriculum. A mixed-methods exploratory sequential approach with embedded design was utilized. Qualitative analysis of didactics curriculum content for the past 2 years was coded according to themes identified in the residency curriculum content, which were further coded according to ACGME milestones. Curriculum topics identified in qualitative analysis were utilized to create a questionnaire that was administered to residents and faculty (n=24) in the ONMM residency program to examine the perceived importance of each curriculum topic based on a five-point Likert scale. Open-ended questions were embedded in the questionnaire that asked how faculty and residents define ONMM and what they believe should be the purpose of an ONMM residency curriculum. Five themes were identified in qualitative analysis of curriculum: (1) OMM laboratory topics; (2) faculty-led activities and lecture topics; (3) resident-led activities and lecture topics; (4) research; and (5) training courses and volunteer activities. The most important perceived curriculum topics for faculty and residents were osteopathic structural examination, orthopedic exam, direct and indirect methods, osteopathic cranial manipulative medicine, pediatric OMT, common upper and lower extremity injuries, and low back pain. Each of these topics aligned well with ACGME milestones. Residents reported that integrative medicine topics such as acupuncture were a significantly more important OMM laboratory topic (mean=3.58, SD=0.996) compared to faculty (mean=2.33, SD=0.985), t (22)=-3.091, p=0.005. Study participants most commonly described ONMM in terms of the specialized knowledge required for the discipline (n=19, 79.2%) and the Tenets of Osteopathy (n=17, 70.8%), and they felt that the purpose of an ONMM residency curriculum should be to gain knowledge (n=20, 83.3%) and become a competent physician (n=19, 79.2%). The present findings were applied to the development of proposed ONMM residency curriculum guidelines and submitted to the American Academy of Osteopathy (AAO) for consideration. They are presented here as a resource for ONMM residencies to develop a program curriculum in alignment with individual program needs.

Retention of tissue texture change after cervical muscle energy and high velocity low amplitude intervention: implications for treatment intervals.

When choosing to incorporate osteopathic manipulative treatment (OMT) into a patient's care, the risk-to-benefit ratio, the choice of treatment technique, as well as the frequency of treatments are always taken into consideration. This has been even more important during the COVID-19 pandemic, in which social distancing has been the best preventative measure to decrease exposure. By increasing treatment intervals, one could not only limit possible exposure/spread of viruses but also decrease the overall cost to the system as well as to the individual. This is an expansion of a previous study in which quantifiable changes in cervical hysteresis characteristics post-OMT were documented utilizing a durometer (Ultralign SA201®; Sigma Instruments; Cranberry, PA USA). This study compared two treatment modalities, muscle energy (ME) and high-velocity low-amplitude (HVLA) postcervical treatment. Subjects in this study were allowed to re-enroll, provided that they could be treated utilizing the alternate treatment modality. By allowing repeat subjects, analysis of the data for lasting effects of OMT could be observed. To determine whether a significant change in cervical hysteresis would be observed after each treatment regardless of a short treatment interval. A total of 34 subjects were retrospectively noted to be repeat subjects from a larger, 213-subject study. These 34 subjects were repeat participants who were treated with two different direct-treatment modalities 7-10days apart. Each subject was randomly assigned to receive a single-segmental ME or HVLA treatment technique directed toward a cervical (C)segment (C3-C5 only). Subjects were objectively measured pretreatment in all cervical segments utilizing the Ultralign SA201®, then treated with cervical OMT to a single segment, and finally reassessed at all cervical levels with the Ultralign SA201® posttreatment to assess for change in cervical hysteresis. Statistically significant or suggestive changes (p-values 0.01-0.08) with good clinical effect size (0.30 or greater) were noted in all four components of the Ultralign SA201® at multiple cervical levels after the first treatment, but only one component (frequency) had a statistically significant change after the second treatment (AA cervical level, p-value 0.01) with good clinical effect size (0.45). However, when comparing the post-first-treatment values to the pre-second-treatment values, no statistically significant differences (p-value 0.10 or higher) were observed between them. Statistically significant changes were noted after the first treatment; however, when comparing cervical hysteresis changes after the first treatment to the cervical hysteresis values prior to the second treatment delivered 7-10days later, there were no statistically significant or suggestive changes. This data suggest that several post-OMT changes noted after the first treatment were still in effect and may indicate that follow-up visits for direct manipulation may be deferred for a least two weeks.

Neurogenic Bowel Dysfunction Changes after Osteopathic Care in Individuals with Spinal Cord Injuries: A Preliminary Randomized Controlled Trial.

Background: Neurogenic bowel dysfunction (NBD) indicates bowel dysfunction due to a lack of nervous control after a central nervous system lesion. Bowel symptoms, such as difficulties with evacuation, constipation, abdominal pain and swelling, are experienced commonly among individuals with spinal cord injury (SCI). Consequentially, individuals with SCI experience a general dissatisfaction with the lower perceived quality of life (QoL). Several studies have demonstrated the positive effects of manual therapies on NBD, including Osteopathic Manipulative Treatment (OMT). This study aimed to explore OMT effects on NBD in individuals with SCI compared with Manual Placebo Treatment (MPT). Methods: The study was a double-blind randomized controlled trial composed of three phases, each one lasting 30 days (i: NBD/drugs monitoring; ii: four OMT/MPT sessions; iii: NBD/drug monitoring and follow-up evaluation). Results: the NBD scale, the QoL on worries and concerns sub-questionnaire, and the perception of abdominal swelling and constipation significantly improved after treatments compared to baseline only for individuals who underwent OMT. Conclusion: These preliminary results showed positive effects of OMT on bowel function and QoL in individuals with SCI, but further studies are needed to confirm our results.

The Effect of Pedal Pump Lymphatic Technique Versus Passive Recovery Following Maximal Exercise: A Randomized Cross-Over Trial

ContextMuscle damage and delayed onset muscle soreness (DOMS) can occur following intense exercise. Various modalities have been studied to improve blood lactate accumulation, which is a primary reason for DOMS. It has been well established that active recovery facilitates blood lactate removal more rapidly that passive recovery due to the pumping action of the muscle. The pedal pump is a manual lymphatic technique used in osteopathic manipulative medicine to increase lymphatic drainage throughout the body. Pedal pump has been shown to increase lymphatic flow and improve immunity. This may improve circulation and improve clearance of metabolites post-exercise.ObjectiveThis study compared the use of pedal pump lymphatic technique to passive supine recovery following maximal exercise.Methods17 subjects (male n = 10, age 23 ± 3.01; female n = 7, age 24 ± 1.8), performed a maximal volume O2 test (VO2 max) using a Bruce protocol, followed by a recovery protocol using either pedal pump technique or supine passive rest for 10 min, followed by sitting for 10 min. Outcome measures included blood lactate concentration (BL), heart rate (HR), systolic blood pressure (SBP) and VO2. Subjects returned on another day to repeat the VO2 max test to perform the other recovery protocol. All outcomes were measured at rest, within 1- minute post-peak exercise, and at minutes 4, 7, 10 and 20 of the recovery protocols. A 2 × 6 repeated measures ANOVA was used to compare outcome measures (p ≤ 0.05).ResultsNo significant differences were found in VO2, HR, or SBP between any of the recovery protocols. There was no significant difference in BL concentrations for recovery at minutes 4, 7, or 10 (p > 0.05). However, the pedal pump recovery displayed significantly lower BL concentrations at minute 20 of recovery (p = 0.04).ConclusionThe pedal pump significantly decreased blood lactate concentrations following intense exercise at recovery minute 20. The use of manual lymphatic techniques in exercise recovery should be investigated further.

Cranial manipulation affects cholinergic pathway gene expression in aged rats.

Age-dependent dementia is a devastating disorder afflicting a growing older population. Although pharmacological agents improve symptoms of dementia, age-related comorbidities combined with adverse effects often outweigh their clinical benefits. Therefore, nonpharmacological therapies are being investigated as an alternative. In a previous pilot study, aged rats demonstrated improved spatial memory after osteopathic cranial manipulative medicine (OCMM) treatment. In this continuation of the pilot study, we examine the effect of OCMM on gene expression to elicit possible explanations for the improvement in spatial memory. OCMM was performed on six of 12 elderly rats every day for 7days. Rats were then euthanized to obtain the brain tissue, from which RNA samples were extracted. RNA from three treated and three controls were of sufficient quality for sequencing. These samples were sequenced utilizing next-generation sequencing from Illumina NextSeq. The Cufflinks software suite was utilized to assemble transcriptomes and quantify the RNA expression level for each sample. Transcriptome analysis revealed that OCMM significantly affected the expression of 36 genes in the neuronal pathway (false discovery rate [FDR] <0.004). The top five neuronal genes with the largest-fold change were part of the cholinergic neurotransmission mechanism, which is known to affect cognitive function. In addition, 39.9% of 426 significant differentially expressed (SDE) genes (FDR<0.004) have been previously implicated in neurological disorders. Overall, changes in SDE genes combined with their role in central nervous system signaling pathways suggest a connection to previously reported OCMM-induced behavioral and biochemical changes in aged rats. Results from this pilot study provide sufficient evidence to support a more extensive study with a larger sample size. Further investigation in this direction will provide a better understanding of the molecular mechanisms of OCMM and its potential in clinical applications. With clinical validation, OCMM could represent a much-needed low-risk adjunct treatment for age-related dementia including Alzheimer's disease.

Acute giardiasis and Chapman reflexes: Musculoskeletal symptoms preceding, during and after infection

Giardiasis is an acute infection caused by Giardia lamblia, which produces profuse secretory diarrhea that can lead to dehydration and electrolyte derangement. Musculoskeletal manifestations resulting because of giardiasis occur due to prolonged inflammation and viscero-somatic reflexes of the pathophysiology for this disease process. By treating the parasitic infection with an antiparasitic agent, as well as treating the somatic dysfunctions with osteopathic manipulative treatment, analgesics and a home exercise program, the patient in the following article experienced an uneventful course of treatment and a complete recovery including resolution of the pain.
