Spinal Segment MRI Perfusion and Diffusion Response to Spinal Manipulation in Low Back Pain Patients

NCT03880500 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 70

Last updated 2023-08-15

No results posted yet for this study

Summary

The main objective is to quantify changes in diffusion and perfusion in the intervertebral disc and adjacent spinal muscle tissue of a spinal segment receiving a spinal manipulative or control intervention using diffusion-weighted magnetic resonance Imaging (MRI) (DWI, used for quantifying diffusion) and intravoxel incoherent motion MRI (IVIM, used for quantifying perfusion).

Additional objectives are to test if clinical parameters such as pain and disability, radiological parameters, or pain-related inflammatory parameters in venous blood have predictive value in relation to these perfusion and diffusion effects, and if these effects correlate to clinical outcome.

An additional objective is to test the repeatability of IVIM-MRI in assessing perfusion changes in musculoskeletal tissue, and, as a positive control, assessing diurnal changes in perfusion and diffusion parameters in spinal tissue of healthy controls.

Spinal Manipulative Therapy

The patient lies in sidelying position, with the hip of the upper leg flexed to 90° and the foot of the flexed leg hooked behind the popliteal space of the downside leg. The chiropractor faces the subject at a 45°-angle, fixates the flexed knee with his own knee/thigh. The fingers of the cephalic hand reach under the patient's upper arm to contact the upside lateral surface of the superior spinous process. The fingers of the caudal hand hook down-side aspect of the spinous process, the forearm contacts the patient's buttock and thigh. The cephalic hand thrusts lateromedially and caudocranially, from upside toward downside (push). The caudal hand thrusts lateromedially in the opposing direction, from downside toward upside (pull). SMT is repeated after the patient turns to left side lying.
