Effect of cranial osteopathic manipulative medicine on cerebral tissue oxygenation.

CONTEXT: The use of cranial osteopathic manipulative medicine (OMM) to alter cerebral tissue oxygen saturation could play a role in the maintenance of cerebral homeostasis. OBJECTIVE: To examine the effects of cranial OMM on cerebral tissue oxygen saturation (S(CT)O(2)) and cardiac autonomic function in healthy adults. METHODS: Cranial OMM augmentation and suppression techniques and sham therapy were randomly applied to healthy adults. During cranial OMM and sham therapy, S(CT)O(2) of the prefrontal cortex was determined bilaterally by using near-infrared spectroscopy. Heart rate, blood pressure, and systemic arterial blood oxygen saturation (SaO(2)) were also measured. Power spectral analysis was applied to continuous 4-minute R-R intervals. Measurements were made during 2-minute baseline periods, during 4-minute applications of the techniques, and during 5-minute recovery periods. RESULTS: Twenty-one adults (age range, 23-32 y) participated in the present study. Differences in mean baseline measurements for the augmentation technique, suppression technique, and sham therapy were not statistically significant for heart rate, blood pressure, SaO(2), left S(CT)O(2), or right S(CT)O(2). During the suppression technique, there was a statistically significant decrease in both left (slope [standard deviation]= -0.33 [0.08] %/min, R(2)=0.85, P=.026) and right (slope [standard deviation]=-0.37 [0.06] %/min, R(2)=0.94, P=.007) S(CT)O(2) with increased cranial OMM time. However, neither the augmentation technique nor the sham therapy had a statistically significant effect on S(CT)O(2). Decreases in normalized low-frequency power of R-R interval variability and enhancements of its high-frequency power were statistically significant (P=.05) during cranial OMM and sham therapy, indicating a decrease in cardiac sympathetic influence and an enhanced parasympathetic modulation. CONCLUSION: The cranial OMM suppression technique effectively and progressively reduced S(CT)O(2) in both prefrontal lobes with the treatment time.

A case-control study of osteopathic palpatory findings in type 2 diabetes mellitus.

BACKGROUND: Although type 2 diabetes mellitus is often managed by osteopathic physicians, osteopathic palpatory findings in this disease have not been adequately studied. METHODS: A case-control study was used to measure the association between type 2 diabetes mellitus and a series of 30 osteopathic palpatory findings. The latter included skin changes, trophic changes, tissue changes, tenderness, and immobility at spinal segmental levels T5-T7, T8-T10, and T11-L2 bilaterally. Logistic regression models that adjusted for age, sex, and comorbid conditions were used to compute odds ratios (ORs) and 95% confidence intervals (CIs) for the associations between type 2 diabetes mellitus and each of these findings. RESULTS AND DISCUSSION: A total of 92 subjects were included in the study. After controlling for age, sex, hypertension, and clinical depression, the only significant finding was an association between type 2 diabetes mellitus and tissue changes at T11-L2 on the right side (OR, 5.54; 95% CI, 1.76-17.47; P = .003). Subgroup analyses of subjects with type 2 diabetes mellitus and hypertension demonstrated significant associations with tissue changes at T11-L2 bilaterally (OR, 27.38; 95% CI, 1.75-428; P = .02 for the left side and OR, 24.00; 95% CI, 1.51-382; P = .02 for the right side). Among subjects with type 2 diabetes mellitus and hypertension, there was also a strong diabetes mellitus duration effect for tissue changes at T11-L2 bilaterally (OR, 12.00; 95% CI, 1.02-141; P = .05 for short duration vs. OR, 32.00; 95% CI, 2.29-448; P = .01 for long duration on the left side; and OR, 17.33; 95% CI, 1.39-217; P = .03 for short duration vs. OR, 32.00; 95% CI, 2.29-448; P = .01 for long duration on the right side). CONCLUSION: The only consistent finding in this study was an association between type 2 diabetes mellitus and tissue changes at T11-L2 on the right side. Potential explanations for this finding include reflex viscerosomatic changes directly related to the progression of type 2 diabetes mellitus, a spurious association attributable to confounding visceral diseases, or a chance observation unrelated to type 2 diabetes mellitus. Larger prospective studies are needed to better study osteopathic palpatory findings in type 2 diabetes mellitus.

Cranial manipulation can alter sleep latency and sympathetic nerve activity in humans: a pilot study.

OBJECTIVE: To determine if cranial manipulation is associated with altered sleep latency. Furthermore, we investigated the effects of cranial manipulation on muscle sympathetic nerve activity (MSNA) as a potential mechanism for altered sleep latency. DESIGN: Randomized block design with repeated measures. SETTING: The Integrative Physiology and Manipulative Medicine Departments, University of North Texas Health Science Center, Fort Worth, TX. SUBJECTS: Twenty (20) healthy volunteers (12 male, 8 female; age range, 22-35 years) participated in this investigation. INTERVENTIONS: Subjects were exposed to 3 randomly ordered treatments: compression of the fourth ventricle (CV4), CV4 sham (simple touch), and control (no treatment). OUTCOME MEASURES: Sleep latency was assessed during each of the treatments in 11 subjects, using the standard Multiple Sleep Latency Test protocol. Conversely, directly recorded efferent MSNA was measured during each of the treatments in the remaining 9 subjects, using standard microneurographic technique. RESULTS: Sleep latency during the CV4 trial was decreased when compared to both the CV4 sham or control trials (p < 0.05). MSNA during the CV4-induced temporary halt of the cranial rhythmic impulse (stillpoint) was decreased when compared to prestillpoint MSNA (p < 0.01). During the CV4 sham and control trials MSNA was not different between CV4 time-matched measurements (p > 0.05). Moreover, the change in MSNA prestillpoint to stillpoint during the CV4 trial was different compared to the CV4 sham and control trials (p < 0.05). However, this change in MSNA was similar between the CV4 sham and control trials (p > 0.80). CONCLUSIONS: The current study is the first to demonstrate that cranial manipulation, specifically the CV4 technique, can alter sleep latency and directly measured MSNA in healthy humans. These findings provide important insight into the possible physiologic effects of cranial manipulation. However, the mechanisms behind these changes remain unclear.

A randomized controlled trial of osteopathic manipulative treatment following knee or hip arthroplasty.

CONTEXT: Preliminary study results suggest that osteopathic manipulative treatment (OMT) may reduce pain, improve ambulation, and increase rehabilitation efficiency in patients undergoing knee or hip arthroplasty. OBJECTIVE: To determine the efficacy of OMT in patients who recently underwent surgery for knee or hip osteoarthritis or for a hip fracture. DESIGN: Randomized controlled trial involving hospital and postdischarge phases. SETTING: Hospital-based acute rehabilitation unit. PATIENTS: A total of 42 women and 18 men who were hospitalized between October 1998 and August 1999. INTERVENTION: Patients were randomly assigned to groups that received either OMT or sham treatment in addition to standard care. Manipulation was individualized and performed according to study guidelines regarding frequency, duration, and technique. MAIN OUTCOME MEASURES: Changes in Functional Independence Measure (FIM) scores and in daily analgesic use during the rehabilitation unit stay; length of stay; rehabilitation efficiency--defined as the FIM total score change per rehabilitation unit day; and changes in Medical Outcomes Study Short Form-36 scores from rehabilitation unit admission to 4 weeks after discharge. RESULTS: Of 19 primary outcome measures, the only significant difference between groups was decreased rehabilitation efficiency with OMT (2.0 vs 2.6 FIM total score points per day; P = .01). Stratified analyses demonstrated that poorer OMT outcomes were confined to patients with osteoarthritis who underwent total knee arthroplasty (length of stay, 15.0 vs 8.3 days; P = .004; rehabilitation efficiency, 2.1 vs 3.4 FIM total score points per day; P < .001). CONCLUSION: The OMT protocol used does not appear to be efficacious in this hospital rehabilitation population.

Improving functional ability in the elderly via the Spencer technique, an osteopathic manipulative treatment: a randomized, controlled trial.

Twenty-nine elderly patients with preexisting shoulder problems voluntarily enrolled as subjects in this study, which was undertaken to determine the efficacy of osteopathic manipulative treatment (OMT) in an elderly population to increase functional independence, increase range of motion (ROM) of the shoulder, and decrease pain associated with common shoulder problems. Each subject had chronic pain, decreased ROM, and/or decreased functional ability in the shoulder before entering the study. Subjects were randomly assigned to either a treatment (OMT) group or a control group for 14 weeks. Over the course of treatment, both groups had significantly increased ROM (P < .01) and decreased perceived pain (P < .01). All subjects continued on their preexisting course of therapy for any concurrent medical problems. After treatment, those subjects who had received OMT demonstrated continued improvement in their ROM, while ROM in the placebo group decreased.

Osteopathic manipulative treatment in conjunction with medication relieves pain associated with fibromyalgia syndrome: results of a randomized clinical pilot project.

Osteopathic physicians caring for patients with fibromyalgia syndrome (FM) often use osteopathic manipulative treatment (OMT) in conjunction with other forms of standard medical care. Despite a growing body of evidence on the efficacy of manual therapy for the treatment of selected acute musculoskeletal conditions, the role of OMT in treating patients with chronic conditions such as FM remains largely unknown. Twenty-four female patients meeting American College of Rheumatology criteria for FM were randomly assigned to one of four treatment groups: (1) manipulation group, (2) manipulation and teaching group, (3) moist heat group, and (4) control group, which received no additional treatment other than current medication. Participants' pain perceptions were assessed by use of pain thresholds measured at each of 10 bilateral tender points using a 9-kg dolorimeter, the Chronic Pain Experience Inventory, and the Present Pain Intensity Rating Scale. Patients' affective response to treatment was assessed using the Self-Evaluation Questionnaire. Activities of daily living were assessed using the Stanford Arthritis Center Disability and Discomfort Scales: Health Assessment Questionnaire. Depression was assessed using the Center for Epidemiological Studies Depression Scale. Significant findings between the four treatment groups on measures of pain threshold, perceived pain, attitude toward treatment, activities of daily living, and perceived functional ability were found. All of these findings favored use of OMT. This study found OMT combined with standard medical care was more efficacious in treating FM than standard care alone. These findings need to be replicated to determine if cost savings are incurred when treatments for FM incorporate nonpharmacologic approaches such as OMT.

Quality of life in referred patients presenting to a specialty clinic for osteopathic manipulative treatment.

Previous research has found that patients of osteopathic physicians tend to report poorer general health perceptions than persons in the general population or than patients of allopathic physicians. Quality of life and level of healthcare satisfaction in patients referred to a specialty clinic for osteopathic manipulative treatment (OMT) at a college of osteopathic medicine were measured in 1997. Data from the Medical Outcomes Study 36-Item Short Form (SF-36) were used to compute standardized scores in the following eight health scales: physical functioning, role limitations because of physical problems, bodily pain, general health perceptions, vitality, social functioning, role limitations because of emotional problems, and mental health. There were 185 patients who returned the survey (mean response rate, 90%), including 22 new and 163 established patients. Patients reported poorer health than the general population on all eight scales (P < .001). Patients frequently reported poorer quality of life than referents with hypertension, congestive heart failure, type 2 diabetes mellitus, recent acute myocardial infarction, or clinical depression. More than 97% of established patients were satisfied or very satisfied with the healthcare received at the clinic. This study suggests that referred patients presenting to osteopathic physicians for OMT may have poorer quality of life than is generally recognized when relying only on traditional diagnostic approaches. Early detection and treatment of musculoskeletal conditions may be important factors in preventing chronicity and its impact on quality of life.
