  • Immediate change in temporal sensory summation [ Time Frame: 10 minutes post-intervention ]
    We will use both behavioral (ratings) and cortical (using fMRI) measures of temporal sensory summation.
  • Change in temporal sensory summation [ Time Frame: 48 hours post-intervention ]
    The change temporal sensory summation (determined using quantitative sensory testing and fMRI) will be calculated from pre-intervention to 48 hours post-intervention

Central Mechanisms of Intervention for Low Back Pain
Central Mechanisms of Body Based Intervention for Musculoskeletal Low Back Pain
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.
170 participants will be randomly assigned to receive one of the interventions or be in a control group. The investigators will use of a model of experimentally induced low back pain to investigate the effects of manipulative and body-based interventions in acute onset low back pain without some of the clinical confounds. The investigators will collect fMRI and psychophysical data about pain sensitivity before and after the induction of pain, and before and after interventions for that pain.
