Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is study testing the feasibility of collecting neurophysiological measures of outcome related to body-based interventions for low back pain. The investigators will collect fMRI and psychophysical data about pain sensitivity before and after the interventions. Participants will be randomly assigned to either spinal manipulation or therapeutic touch groups. Participants will attend two practice sessions prior to the first data collection. There will be two follow-up assessments.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Participants will be enrolled from VA pain clinical at the North Florida/South George VA Medical Center.

The investigators will collect functional magnetic resonance imaging data of resting state and pain-related events (i.i. during thermal pain sensitivity testing, as well as psychophysical data to determine pain sensitivity. Pain sensitivity will be measured using thermal and mechanical stimuli. These data will be collected before and after the interventions, in addition to two follow-up sessions after intervention.

In addition, clinical measures of pain intensity in the low back, as well as trunk range of motion and strength will also be collected.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Spinal manipulation

Participants will receive a lumbar SMT technique previously described in the literature and commonly utilized for the treatment of low back pain . The SMT will be performed four times (two times on each side) in a 5-minute period. In addition, the following will be performed: Functional MRI (fMRI), Behavioral: Pain Sensitivity Testing, Questionnaires,Behavioral: Physical Impairment.

Group Type EXPERIMENTAL

Spinal manipulation

Intervention Type PROCEDURE

Participants will receive a lumbar SMT technique previously described in the literature and commonly utilized for the treatment of low back pain . The SMT will be performed four times (two times on each side) in a 5-minute period. In addition, the following will be performed: Functional MRI, Behavioral: Pain Sensitivity Testing, Questionnaires,Behavioral: Physical Impairment.

fMRI

Intervention Type PROCEDURE

Both groups will receive an fMRI.

Pain Sensitivity Testing

Intervention Type BEHAVIORAL

Both groups will receive an Pain Sensitivity Testing

Questionnaires

Intervention Type OTHER

Both groups will receive Questionnaires

Physical Impairment

Intervention Type BEHAVIORAL

Both groups will receive testing on physical impairment.

Therapeutic touch

Participants in this group will lie prone. The therapist will place both hands in contact with the participants' pelvis across the top of the posterior aspect of the sacrum and ilia and apply a downward force to keep the pelvis in contact with the table. This group accounts for effects of time and personal contact. The amount of "hands-on" contact will be equivalent between groups. Both groups will be given the same verbal instructions regarding the techniques performed. In addition, the following will be performed: Functional MRI (fMRI), Behavioral: Pain Sensitivity Testing, Questionnaires,Behavioral: Physical Impairment.
