Effects of osteopathic manipulative treatment on children with plagiocephaly in the context of current pediatric practice: a retrospective chart review study.

CONTEXT: Deformational plagiocephaly (DP) is on the rise in pediatric patients. The current standard of care recommended for management is repositioning with possible addition of cranial orthoses. However, strong data are lacking to support these recommendations. Osteopathic manipulative treatment (OMT) is another treatment option for DP that is also lacking evidential support. OBJECTIVES: This retrospective chart review study investigated the effects of OMT at restoring a more symmetrical cranial bone configuration in children with DP. METHODS: A retrospective chart review was performed on medical records of patients with a diagnosis of DP from three private practices over a 4-year period from September 2017 to December 2021. Inclusion criteria were diagnoses of DP by a referring physician and aged 10 months or less at the time of initial evaluation and treatment. Patients were excluded if they had confounding diagnoses such as genetic syndromes or severe torticollis. A total of 26 patients met these criteria, and their records were reviewed. The main outcome reviewed was anthropometric assessment of the cranium, mainly the cranial vault asymmetry index (CVAI). RESULTS: Participants demonstrated a mean CVAI - a measure that determines the severity of DP - of 6.809 (±3.335) (Grade 3 severity) at baseline, in contrast to 3.834 (±2.842) (Grade 2 severity) after a series of OMT treatments. CVAI assessment after OMT reveals statistically significant (p≤0.001) decreases in measurements of skull asymmetry and occipital flattening. No adverse events were reported throughout the study period. CONCLUSIONS: The application of OMT has shown potential benefit for reducing cranial deformity in patients with DP.

Osteopathic manipulative treatment of back pain and related symptoms during pregnancy: a randomized controlled trial.

OBJECTIVE: To study osteopathic manipulative treatment of back pain and related symptoms during the third trimester of pregnancy. STUDY DESIGN: A randomized, placebo-controlled trial was conducted to compare usual obstetric care and osteopathic manipulative treatment, usual obstetric care and sham ultrasound treatment, and usual obstetric care only. Outcomes included average pain levels and the Roland-Morris Disability Questionnaire to assess back-specific functioning. RESULTS: Intention-to-treat analyses included 144 subjects. The Roland-Morris Disability Questionnaire scores worsened during pregnancy; however, back-specific functioning deteriorated significantly less in the usual obstetric care and osteopathic manipulative treatment group (effect size, 0.72; 95% confidence interval, 0.31-1.14; P = .001 vs usual obstetric care only; and effect size, 0.35; 95% confidence interval, -0.06 to 0.76; P = .09 vs usual obstetric care and sham ultrasound treatment). During pregnancy, back pain decreased in the usual obstetric care and osteopathic manipulative treatment group, remained unchanged in the usual obstetric care and sham ultrasound treatment group, and increased in the usual obstetric care only group, although no between-group difference achieved statistical significance. CONCLUSION: Osteopathic manipulative treatment slows or halts the deterioration of back-specific functioning during the third trimester of pregnancy.

Lymph flow in the thoracic duct of conscious dogs during lymphatic pump treatment, exercise, and expansion of extracellular fluid volume.

BACKGROUND: This investigation examined interactions between expansion of the extracellular fluid volume (ECE), osteopathic lymphatic pump treatment (LPT), and exercise on lymph flow in the thoracic duct of eight instrumented, conscious dogs. METHODS AND RESULTS: After recovery from surgery, LPT was performed for 8 min before and after ECE with normal saline, i.v., 4.4+/-0.3% of body weight. Baseline lymph flow was 1.7+/-0.5 mL/min. LPT rapidly increased lymph flow to 5.0+/-1.1 mL/min at 1 min, and lymph flow remained above baseline for 4 min (p<0.05). LPT produced a net increase in lymph flow of 15.4+/-1.1 mL. Following ECE, baseline lymph flow was 4.8+/-0.6 mL/min (p<0.05). LPT increased lymph flow to 9.9+/-1.1 mL/min at 1 min (p<0.05), and lymph flow remained above baseline for 4 min (p<0.05); all flow values after ECE were greater than corresponding values before ECE. However, the net increase in lymph flow produced by 8 min of LPT (18.3+/-3.8 mL) was not significantly greater than that observed before ECE. Moderate treadmill exercise increased lymph flow for 4 min before ECE and for 6 min after ECE. All lymph flows during exercise were greater after ECE than before ECE. The net increase in lymph flow produced by 8 min of exercise was 24.9+/-5.5 mL before ECE and 39.6+/-5.1 mL after ECE (p<0.05). CONCLUSIONS: Expansion of the extracellular fluid volume produced large increases in thoracic duct lymph flow, that were further augmented by lymphatic pump treatment and by moderate treadmill exercise.

Abdominal lymphatic pump treatment increases leukocyte count and flux in thoracic duct lymph.

BACKGROUND: Previous studies suggest that rhythmic compression of the abdomen (abdominal lymphatic pump techniques, LPT) enhances immunity and resistance to infectious disease, but direct evidence of this has not been documented. In this study, the thoracic duct of eight anesthetized mongrel dogs was catheterized, so the immediate effects of LPT on lymph flow and leukocyte output could be measured. METHODS AND RESULTS: Lymph flow was measured by timed collection or ultrasonic flowmeter, and lymph was collected over ice under 1) resting (baseline) conditions, and 2) during application of LPT. The baseline leukocyte count was 4.8 +/- 1.7 x 10(6) cells/ml of lymph, and LPT significantly increased leukocytes to 11.8 +/- 3.6 x 10(6) cells/ml. Flow cytometry and differential cell staining revealed that numbers of macrophages, neutrophils, total lymphocytes, T cells and B cells were similarly increased during LPT. Furthermore, LPT significantly enhanced lymph flow from 1.13 +/- 0.44 ml/min to 4.14 +/- 1.29 ml/min. Leukocyte flux, computed from the product of lymph flow and cell count, was increased by LPT from 8.2 +/- 4.1 x 10(6) to 60 +/- 25 x 10(6) total cells/min. Similar trends were observed in macrophages, neutrophils, total lymphocytes, T cells and B cells during LPT. CONCLUSIONS: LPT significantly increased both thoracic duct lymph flow and leukocyte count, so lymph leukocyte flux was markedly enhanced. Increased mobilization of immune cells is likely and important mechanism responsible for the enhanced immunity and recovery from infection of patients treated with LPT.

Thermography Examination of Abdominal Area Skin Temperatures in Individuals With and Without Focal-Onset Epilepsy.

Early osteopathic theory and practice, and the work of the medical intuitive Edgar Cayce suggested that the abdominal areas of individuals with epilepsy would manifest "cold spots." The etiology for this phenomenon was thought to be abdominal adhesions caused by inflammation and viscero-somatic reflexes caused by adhesions or injury to visceral or musculoskeletal system structures. Indeed, until that advent of electroencephalography in the 1930s, medical practice regarding epilepsy focused on abdominal neural and visceral structures. Following two hypotheses were formulated to evaluate any abdominal temperature phenomena: (1) an abdominal quadrant division analysis would find one or more quadrants "colder" in the focal-onset epilepsy group (ICD9-CM 345.4 and 345.5) compared to controls. (2) Total abdominal areas of individuals with focal-onset epilepsy wound be colder than a control group. METHODS: Overall, 50 patients with the diagnosis of focal-onset epilepsy were recruited from the office of the Epilepsy Foundation of Florida and 50 control subjects with no history of epilepsy were recruited through advertising to the public. Under controlled room conditions all subjects had infrared thermographic images made and recorded by Med-Hot Model MH-731 FLIR equipment. RESULTS: There were no significant demographic difference between experimental patients and control subjects, though the control group tended to be younger and more often male; however, these were controlled for in all analyses. In the quadrant analysis, there were significant differences in that more epileptic patients had colder left upper abdominal quadrant temperatures than the control group (66.8% versus 44.9%; P = .030). In the total abdominal analysis, however, there were no significant differences. DISCUSSION: The results support the hypothesis that individuals with focal-onset epilepsy have colder abdominal areas. If substantiated in further research, present study results will require further examination of the mechanisms of action for epilepsy, and suggest the need for re-examination of older formulations of abdominal epilepsy, including the place of abdominal injury, inflammation, and adhesions in epileptic pathology. The concept of somato-visceral and viscero-somatic neurological interactions is one of the possible mechanisms underlying the "cold spot" findings and warrants further consideration.

Lymphatic pump treatment as an adjunct to antibiotics for pneumonia in a rat model.

BACKGROUND: Lymphatic pump treatment (LPT) is a technique used by osteopathic physicians as an adjunct to antibiotics for patients with respiratory tract infections, and previous studies have demonstrated that LPT reduces bacterial load in the lungs of rats with pneumonia. Currently, it is unknown whether LPT affects drug effcacy. OBJECTIVE: To determine whether the combination of antibiotics and LPT would reduce bacterial load in the lungs of rats with acute pneumonia. METHODS: Rats were infected intranasally with 5×107 colony-forming units (CFU) of Streptococcus pneumoniae. At 24, 48, and 72 hours after infection, the rats received no therapy (control), 4 minutes of sham therapy, or 4 minutes of LPT, followed by subcutaneous injection of 40 mg/kg of levofoxacin or sterile phosphate-buffered saline. At 48, 72, and 96 hours after infection, the spleens and lungs were collected, and S pneumoniae CFU were enumerated. Blood was analyzed for a complete blood cell count and leukocyte differential count. RESULTS: At 48 and 72 hours after infection, no statistically significant differences in pulmonary CFU were found between control, sham therapy, or LPT when phosphate-buffered saline was administered; however, the reduction in CFU was statistically significant in all rats given levofoxacin. The combination of sham therapy and levofoxacin decreased bacterial load at 72 and 96 hours after infection, and LPT and levofoxacin significantly reduced CFU compared with sham therapy and levofoxacin at both time points (P<.05). Colony-forming units were not detected in the spleens at any time. No statistically significant differences in hematologic findings between any treatment groups were found at any time point measured. CONCLUSION: The results suggest that 3 applications of LPT induces an additional protective mechanism when combined with levofoxacin and support its use as an adjunctive therapy for the management of pneumonia; however, the mechanism responsible for this protection is unclear.

Osteopathic manipulative treatment in prenatal care: a retrospective case control design study.

The use of osteopathic manipulative treatment (OMT) during pregnancy has a long tradition in osteopathic medicine. A retrospective study was designed to compare a group of women who received prenatal OMT with a matched group that did not receive prenatal OMT. The medical records of 160 women from four cities who received prenatal OMT were reviewed for the occurrence of meconium-stained amniotic fluid, preterm delivery, use of forceps, and cesarean delivery. The randomly selected records of 161 women who were from the same cities, but who did not receive prenatal OMT, were reviewed for the same outcomes. The results of a logistic regression analysis were statistically reliable, chi2 (4, N = 321) = 26.55; P < .001, indicating that the labor and delivery outcomes, as a set, were associated with whether OMT was administered during pregnancy. According to the Wald criterion, prenatal OMT was significantly associated with meconium-stained amniotic fluid (Z = 13.20, P < .001) and preterm delivery (Z = 9.91; P < .01), while the use of forceps was found to be marginally significant (Z = 3.28; P = .07). The case control study found evidence of improved outcomes in labor and delivery for women who received prenatal OMT, compared with women who did not. A prospective study is proposed as the next step in evaluating the effects of prenatal OMT.

Somatic dysfunction and use of osteopathic manual treatment techniques during ambulatory medical care visits: a CONCORD-PBRN study.

CONTEXT: Osteopathic manual treatment (OMT) of somatic dysfunction is a unique approach to medical care that may be studied within a practice-based research network. OBJECTIVE: To measure patient characteristics and osteopathic physician practice patterns within the Consortium for Collaborative Osteopathic Research Development-Practice-Based Research Network (CONCORD-PBRN). DESIGN: Cross-sectional card study. SETTING: Eleven member clinics within the CONCORD-PBRN coordinated by The Osteopathic Research Center. PATIENTS: A total of 668 patients seen between January and March 2013. MAIN STUDY MEASURES: Patient age and sex; primary diagnoses; somatic dysfunction as manifested by tenderness, asymmetry, restricted motion, or tissue texture changes; and use of 14 OMT techniques. Results were stratified by anatomical region and adjusted for clustering within member clinics. Clustering was measured by the intracluster correlation coefficient. RESULTS: Patient ages ranged from 7 days to 87 years (adjusted mean age, 49.2 years; 95% confidence interval [CI], 43.3-55.1 years). There were 450 females (67.4%) and 508 patient visits (76.0%) involved a primary diagnosis of disease of the musculoskeletal system and connective tissue. Structural examination was performed during 657 patient visits (98.4%), and 649 visits (97.2%) involved OMT. Restricted motion and tenderness were the most and least common palpatory findings, respectively. Cranial (1070 [14.5%]), myofascial release (1009 [13.7%]), muscle energy (1001 [13.6%]), and counterstrain (980 [13.3%]) techniques were most commonly used, accounting for more than one-half of the OMT provided. Pediatric patients were more likely than adults to receive OMT within the head (adjusted odds ratio [OR], 9.53; 95% CI, 1.28-71.14). Geriatric patients were more likely than adults to receive a structural examination (adjusted OR, 1.83; 95% CI, 1.09-3.07) and OMT (adjusted OR, 1.62; 1.02-2.59) within the lower extremity. Females were more likely than males to receive a structural examination (adjusted OR, 2.44; 95% CI, 1.44-4.16) and OMT (adjusted OR, 2.11; 95% CI, 1.26-3.52) within the sacrum and OMT within the pelvis (adjusted OR, 1.79; 95% CI, 1.12-2.88). Intracluster correlation coefficients for the 4 most commonly used OMT techniques ranged from 0.34 to 0.72. CONCLUSION: This study provides proof of concept of the feasibility of studying osteopathic medical practice on a national level by developing and growing the CONCORD-PBRN.

Lymphatic pump treatment repeatedly enhances the lymphatic and immune systems.

BACKGROUND: Osteopathic practitioners utilize manual therapies called lymphatic pump techniques (LPT) to treat edema and infectious diseases. While previous studies examined the effect of a single LPT treatment on the lymphatic system, the effect of repeated applications of LPT on lymphatic output and immunity has not been investigated. Therefore, the purpose of this study was to measure the effects of repeated LPT on lymphatic flow, lymph leukocyte numbers, and inflammatory mediator concentrations in thoracic duct lymph (TDL). METHODS AND RESULTS: The thoracic ducts of five mongrel dogs were cannulated, and lymph samples were collected during pre-LPT, 4 min of LPT, and 2 hours post-LPT. A second LPT (LPT-2) was applied after a 2 hour rest period. TDL flow was measured, and TDL were analyzed for the concentration of leukocytes and inflammatory mediators. Both LPT treatments significantly increased TDL flow, leukocyte count, total leukocyte flux, and the flux of interleukin-8 (IL-8), keratinocyte-derived chemoattractant (KC), nitrite (NO2(-)), and superoxide dismutase (SOD). The concentration of IL-6 increased in lymph over time in all experimental groups; therefore, it was not LPT dependent. CONCLUSION: Clinically, it can be inferred that LPT at a rate of 1 pump per sec for a total of 4 min can be applied every 2 h, thus providing scientific rationale for the use of LPT to repeatedly enhance the lymphatic and immune system.
