Central Mechanisms of Intervention for Low Back Pain

Completed · Not applicable

Conditions studied: Low Back Pain

In brief

Body-based interventions have consistently shown clinical effectiveness in patients with back pain. The primary objective for this study is to compare the effect of body-based interventions commonly used in the management of low back pain on behavioral and cortical measures of pain sensitivity and central sensitization of pain. Participants will be randomly assigned to receive one of the interventions or be in a control group. The central hypothesis for this proposal is that spinal manipulation, a specific form of body-based intervention, inhibits central sensitization of pain normalizing pain sensitivity more rapidly than other interventions. The completion of the proposed study will elucidate underpinning mechanisms of body-based interventions. Identification of these mechanisms will improve the clinical application and utilization of these interventions in the management of musculoskeletal pain conditions, especially back pain.
