OMT of Somatic Dysfunction and Chronic Low Back Pain in Patients With Type 2 Diabetes Mellitus

Osteopathic Manipulative Treatment of Somatic Dysfunction and Chronic Low Back Pain in Patients With Type 2 Diabetes Mellitus

The study hypothesis is based on osteopathic medical philosophy that: 1) the body is a unit; 2) the body has inherent self-regulatory mechanisms; 3) structure and function are interrelated; and 4) rational treatment is based on an understanding and integration of these concepts. Patients with type 2 diabetes mellitus often report more aches and pains than people without diabetes. Because osteopathic manual medicine addresses dysfunction in the musculoskeletal system, patients with both chronic low back pain and type 2 diabetes mellitus may benefit from this non-pharmacological treatment to reduce their pain, thereby reducing their stress and perhaps providing better clinical control for diabetes as demonstrated by key markers such as hemoglobin A1c and kidney function. This study is an extension of research completed in the OSTEOPATHIC Trial. Results of that study were published in the Annals of Family Medicine in March/April 2013.

SPECIFIC AIM 1:

To conduct a randomized controlled trial (RCT) to determine the efficacy of osteopathic manual treatment (OMT) vs sham OMT in subjects with type 2 diabetes mellitus (T2DM) and comorbid chronic low back pain (LBP). This will involve a 12-week protocol to study changes in response to OMT in such outcomes as LBP severity (primary outcome measure), somatic dysfunction, renal function, glycemic control, and other biomarkers potentially related to T2DM.

SPECIFIC AIM 2:

Within the RCT, to corroborate previous findings indicating that patients with T2DM have a high prevalence of tissue texture abnormalities in the T11-L2 spinal segmental region and to determine if such findings can be statistically associated with the presence of diabetic nephropathy using such laboratory measures as serum creatinine, urinary microalbuminuria and macroalbuminuria, and the glomerular filtration rate.

SPECIFIC AIM 3:

Within the RCT, to explore potential mechanisms of action of OMT by longitudinally measuring concentrations of biomarkers such as insulin, glucagon, cortisol, hemoglobin A1c, tumor necrosis factor-α,interleukin (IL)-1β, IL-6, IL-10, and IL-18 in subjects with T2DM and comorbid chronic LBP over 12 weeks. Significant changes in biomarker concentrations may help explain the effects of OMT and whether such effects are mediated by changes in somatic dysfunction.

Subjects will also be excluded if any of the following conditions are found during the clinical screening:

3. active bleeding or infection in the lower back, or any other condition that might impede protocol implementation; OR
4. discovery of the presence of any telephone screening exclusion criterion (EXCEPT that the usual LBP severity over the past week may have declined from ≥4/10 points to ≥3/10 points during the lag time between screenings).
