A recent randomized trial of yoga and exercise in patients with multiple sclerosis evaluated the effect of yoga and aerobic conditioning on several quality-of-life endpoints: fatigue, cognitive function and mood. There was a trend suggesting improvement in mood and there were no statistically significant differences in cognitive function 9 between groups. Latha investigated the use of Hatha yoga for the treatment of headaches in a series of randomized controlled clinical trials and demonstrated a significant reduction in 8 headaches, use of medications and perception of stress in the group receiving yoga therapy. Other clinical trials have shown that Hatha yoga may be useful in the treatment 5–7,10 of hypertension. One of these studies found that daily practice of Hatha yoga was as effective as pharmacological agents at reducing blood pressure. Forward bends and inversions, and their modifications, are felt to be particularly beneficial for hypertension. Garfinkel and colleagues (1998) published a study in the Journal of the American Medical Table 1 Clinical trials in Hatha yoga Diagnosis Reference Type of study Chronic pain (carpal 2 randomized clinical trial tunnel syndrome) Chronic pain 3 observational study (osteoarthritis) Chronic pain 4 controlled clinical trial (rheumatoid arthritis) Hypertension 5 uncontrolled clinical trial Hypertension 6 prospective clinical trial Hypertension 7 randomized, placebocontrolled clinical trial Headaches 8 randomized controlled clinical trial Low back pain Pilot study in progress—Kaiser controlled clinical trial Permanente and Brad Jacobs, UCSF, San Francisco, CA Postpolio syndome Pilot study in progress—Conemaugh controlled clinical trial Health System, Barbara Duryea, Johnstown, PA Hatha yoga and meditation for neurological conditions 193 Association demonstrating that Hatha yoga was useful in the treatment of carpal tunnel 2 syndrome. In this clinical trial patients with carpal tunnel syndrome were given 11 Hatha yoga postures to perform. The control group was given a splint to augment their current treatment regime; nothing else was added to their treatment. The group treated with the 11 Hatha yoga postures showed significant improvement in grip strength, pain reduction and range of motion. The same authors also evaluated Hatha yoga for pain relief in the 3 treatment of osteoarthritis of the hand.
This progression of pain and somatic findings in visceral disturbances have been extensively documented by 90 500 mg flagyl with amex,91 128 osteopathic physicians in the USA, by surgeons at the Mayo Clinic Foundation, and 129,130 by pain management specialists world wide. From a treatment perspective, primary somatic dysfunction typically responds well to 51,131 the various management strategies as previously discussed, whereas somatic 90,132 dysfunction secondary to visceral disorders responds variably and often recurs when addressed by these approaches alone. Maigne indicates that, when cervical somatic dysfunction is eliminated with manipulation, precipitating visceral factors that are still present will no longer trigger the 134 referred headaches. Travell and Simons noted that non-responsive gastric ulcers previously responsive to medication became nonresponsive in the presence of myofascial trigger points in the anterior thoracoabdominal region and did not respond to medication 135 again until this somatic dysfunction was removed. The segmental facilitation model has held up well in the correlations seen between the level of spinal somatic dysfunction and the autonomic innervation level associated with a given organ that is dysfunctional or diseased (refer back to Figure 3). To date, the sensitivity and specificities of the points tested have averaged 80% and their use in a blinded series of gynecological problems Osteopathic considerations in neurology 103 resulted in 80% sensitivity for the presence of ovarian disease and a 95% accuracy for 136 identifying the side of involvement. The integration of palpation data in the differential diagnosis of systemic disorders and suggestions for the use of OMT for removing somatic dysfunction to augment homeostatic mechanisms in the neural, vascular and lymphatic areas of a patient can be 90 found in the text Osteopathic Considerations in Systemic Dysfunction. Figure 13 Comparison of somatic dysfunction locations in patients with cardiac and gastrointestinal diagnoses Palpation to identify somatic dysfunction in hospitalized patients as an aid to making a differential diagnosis has maintained its prioritization. However, as diagnosis related group (DRG)-regulated hospital stays have both decreased in duration and increased in the severity of illness, the use of in-hospital OMT has dropped significantly. Today, most osteopathically delivered OMT is in the out-patient setting and studies indicate that the coding for that procedure is primarily associated with neuromusculoskeletal (somatic) diagnoses. Nonetheless, research, currently underway, suggests that intervention with OMT in certain categories of hospitalized care may be effective in decreasing the need for postoperative pain medications, providing earlier post-surgical ambulation for patients 137 who have undergone orthopedic lower extremity procedures and decreasing length of stays in general. Perhaps this is the result of decreasing side-effects of the alternative use of certain medications or reducing the need for intravenous catheters and intravenous 138 medication. The presence of moderate to severe somatic dysfunction in particular spinal patterns correlates with and thereby augments the differential diagnosis of a wide range of 90,128,139 visceral conditions. Indeed, irritationof upper thoracic spinal joint receptors simultaneously evokes numerous reflex alterations, including paravertebral muscle spasm 140 and alterations in endocrine, respiratory and cardiovascular functions. Specific palpatory findings of upper thoracic somatic dysfunction (especially affecting left upper thoracic paraspinal tissues) were reported in the British 141 Medical Journal as being consistently found in myocardial infarction. These palpatory findings of somatic dysfunction have a completely different pattern of distribution from the 139 secondary somatic dysfunction associated with patients with gastrointestinal problems (Figure 13).
