Feasibility Assessment of Neurophysiological Measurement in Veterans With LBP
CENTRAL MECHANISMS OF BODY BASED INTERVENTION FOR MUSCULOSKELETAL LOW BACK PAIN: Feasibility Assessment of Neurophysiological Measurement in Veterans With Low Back Pain
調査の概要
状態
条件
詳細な説明
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.

実験的: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.

偽コンパレータ: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.

This measure thermal threshold and tolerance using continuous heat stimulus delivered to the participants' dominant arm.
The stimulus will start at 35°C and will be increased at a rate of 0.5°C with participants terminating the stimulus when the temperature reached pain threshold ("when the sensation first transitions from heat to pain") and tolerance ("when the sensation becomes so strong you want to remove it from your skin").
Threshold and tolerance measures will also be collected using mechanical pressure applied using a Fischer Dolorimeter.
During Dolorimeter testing, force is slowly increased until the subject indicates that the sensation changes from pressure to pain.

Pain Intensity
時間枠:Change from Day 3, Day 4 and Day 5
|
Pain visual analog scale is a 10cm long line.
The line is anchored at one end with 'none' or 'not bad at all' and at the other with 'worst imaginable.' Participants are asked to rate their pain at rest by placing a mark along the 10cm line.
Participants will also rate pain during active trunk range of motion using the same scale.

McGill Pain Questionnaire-2
時間枠:Change from Day 3, Day 4 and Day 5
|
This is 22-item questionnaire that asks participants to describe the intensity of varies qualities of the pain that he or she is experiencing; for example, throbbing or itching.
|

Physical Impairment
時間枠:Change from Day 3, Day 4 and Day 5
|
A physical impairment scale consists of 7 different examination procedures that assess lumbar and hip range of motion, muscle performance of trunk musculature, and response to palpation.
Scores is 0 - 8, Range is 0 is no impairment and 8 is completely impaired.

Oswestry Disability Questionnaire (ODQ)
時間枠:Change from Day 3, Day 4 and Day 5
|
The ODQ has a range of 0 (no disability due to back pain) to 100 (completely disabled due to back pain), so higher scores indicate higher disability from LBP.
