Effects of Osteopathic Manipulative Treatment and Bio Electro-Magnetic Regulation Therapy on Low Back Pain in Adults.

Low back pain (LBP) has become a major challenge in our society and has a relatively high incidence and prevalence. Moreover, LBP currently affects people of all ages and is a leading contributor to disease burden worldwide . Individuals affected by LBP may experience this discomfort and associated disability for several months, and a proportion may remain severely disabled. For nearly all people with low back pain, it is not possible to identify a specific nociceptive cause. Most people with new episodes of LBP may recover quickly; however, recurrence is common and in many cases, LBP becomes persistent and disabling.

Despite the overabundance of treatments and approaches devoted to LBP, this back related disability and the number of individuals affected have steadily been increasing. During the past three decades, changes have been made to key recommendations in national clinical practice guidelines. In fact, currently there is a bigger emphasis placed on self-management, physical and psychological therapies, and some forms of complementary medicine (such as spinal manipulation, massage, acupuncture), and less emphasis on pharmacological and surgical treatments.

Despite multiple clinical guidelines providing similar recommendations for managing low back pain, a substantial gap between evidence and practice exists. Osteopathic manipulative treatment (OMT) is a distinctive modality used by osteopathic physicians to complement conventional management of LBP. There is considerable variability in OMT approaches when treating for LBP. Furthermore, osteopathic physicians combine conventional and complementary treatments when caring for patients with LBP. This increased variability in the approach to care for LBP patients requires more empirical data to determine the best approaches to treat LBP. Franke et al. conducted a meta-analysis that investigated the effect of OMT in LBP. The authors reported that some studies observed significant effect of OMT on pain, whereas other reported either a non-significant effect, or an effect in favor of the control treatment. It is clear that more research to better describe the effects of OMT on LBP is warranted.

OMT is the application of hands-on forces to help improve physiologic function and/or support homeostasis that has been negatively altered by somatic dysfunction, which is an impairment of function of any area of the body system. These impairments can occur at the muscles, fascia, bones, joints, ligaments, vasculature, lymphatics and nerves. When somatic dysfunction is diagnosed, using an osteopaths’ manual palpatory skills, it is treated with OMT. In general, OMT techniques can be classified as direct or indirect. Direct techniques such as muscle energy (ME), high velocity low amplitude (HVLA), soft tissue (ST), and myofascial release (MFR) engage the restrictive barrier and use a specifically applied force to correct the somatic dysfunction . Indirect techniques such as MFR, counterstrain (CS), balanced ligamentous tension (BLT) disengage from the restrictive barrier and the affected body part is moved into its freedom of motion.

The etiology of low back pain is varied from visceral causes, to a lack of adequate blood flow to the muscles and musculoskeletal imbalance. Inadequate blood supply and/or inadequate oxygen consumption can influence muscle pain. The role of OMT is thought to primarily address the musculoskeletal component of back pain, which may help improve muscle blood flow. Two of the primary goals of treatment with osteopathic techniques are to restore mobility and decrease pain. Using trained palpatory skills to diagnose alterations in the fascial connections within the body, it is proposed that OMT techniques can help alleviate these alterations in the body that may lead to musculoskeletal disorders such as low back pain. Many studies that use OMT as the intervention to reduce low back pain, utilize a combination of direct and indirect techniques. The use of myofascial release technique has been shown to increase mobility of the lumbar myofascial tissues, visceral motion and decrease pain in patients with non-specific low back pain using ultrasound diagnostics.

One very promising alternative approach for the treatment of LBP is the use of Bio Electro-Magnetic Regulation (BEMER) Therapy. BEMER is a therapeutic modality that deploys a biorhythmically defined stimulus through a Pulsed Electromagnetic Field (PEMF). This stimulus has a targeted effect on the microvasculature, and the primary effect is an improvement in tissue microcirculation. The positive effects of vasomotion on the microcirculation has been shown to result in significant increases in arteriovenous oxygen difference, number of open capillaries, arteriolar and venular flow volume, and flow rate of red blood cells in the microvasculature. Therefore, BEMER can potentially be used in the treatment of LBP by improving microcirculation in muscular tissue.

Though OMT has been shown to be effective clinically for patients in decreasing pain, little is known behind the specific mechanisms of action. It is believed all osteopathic techniques use the concepts of fascial connectivity throughout the body and therefore can help increase circulation and lymphatic flow. In one study, the use of OMT helped decrease autonomic and neuroendocrine markers in response to mental stress. In modeled studies, OMT modalities like MFR and CS showed possible effects in modifying cytokine secretion, improving wound healing, and modifying muscle contraction. These effects were shown to sometimes reverse repetitive muscle strain in the tissues. It is postulated that these strains may represent the phenomenon of somatic dysfunction. Another study showed improvement in lower extremity blood pressure, cell mass, intracellular water, basal metabolism, venous velocity, skin temperature, pain, and quality of life post MFR and physical therapy for post-menopausal women with venous insufficiency. As discussed previously, BEMER therapy has been shown to increase microcirculation. BEMER with physiotherapy showed reductions in pain and fatigue acutely in patients with chronic low back pain. A systemic review of randomized controlled trials that investigated whether PEMF was effective in low back pain showed there was decrease in pain intensity and improved functionality in individuals with different low back pain conditions . Therefore the results from these studies suggest that the combination of OMT and BEMER therapy can potentially help increase circulation to myofascial structures that influence low back restriction and pain.
