Examining Effects of Aerobic Exercise on Pain Sensation

Not Applicable
Completed
Conditions
Chronic Low Back Pain
Interventions
Behavioral: Aerobic exercise program
Registration Number
NCT03546153
Lead Sponsor
University of Kansas Medical Center
Brief Summary

By doing this study, researchers hope to learn effects of aerobic exercise on over activated nervous system in people with chronic low back pain.

Detailed Description

Chronic low back pain is a common condition in the world. About 85% of people with low back pain do not know the cause of their pain. This leads to ineffective treatments.

Recently, the idea of an over activated nervous system is thought to be one of the main reasons for chronic pain. Over activated nervous system means pain processing areas in the spine or brain might be more sensitive. Aerobic exercise, such as walking and cycling, is often used to decrease chronic pain. Aerobic exercise is a form of physical exercise that strengthen the heart and lungs in order to improve the body's utilization of oxygen.

The researchers want to examine if aerobic exercise is effective in decreasing over activation of the nervous system. Gaining a better understanding of effects of aerobic exercise on the nervous system may lead to more effective treatments for low back pain.

Primary Outcome Measures
NameTimeMethod
Opioid consumptionChange from Baseline (pre-treatment) to after completion of 3 months of aerobic exercise training (post-treatment)

Use of opioids (dose, frequency, and duration) will be obtained by interviewing the subjects

Pain sensitivity (Pressure pain threshold)Change from Baseline (pre-treatment) to after completion of 3 months of aerobic exercise training (post-treatment)

Sensitivity will be measured using a pressure algometer.

2011 FM surveyChange from Baseline (pre-treatment) to after completion of 3 months of aerobic exercise training (post-treatment)

Sensitivity will be measured using the 2011 Fibromyalgia (FM) Survey Criteria. The survey includes widespread pain index and symptom severity scale. The total score is 31 and scores more than 13 is considered fibromyalgia positive, suggesting presence of central sensitization.

Oswestry Disability IndexChange from Baseline (pre-treatment) to after completion of 3 months of aerobic exercise training (post-treatment)

This questionnaire consists of questions related to daily functions and degrees to which back pain interferes with these functions. Each items is measured on a 6-point scale with a total possible score of 50. Higher numbers indicate greater disability.

Secondary Outcome Measures
NameTimeMethod
Pittsburgh Sleep Quality IndexChange from Baseline (pre-treatment) to after completion of 3 months of aerobic exercise training (post-treatment)

Pittsburgh sleep quality index contains 19 questions, creating 7 components that produce one global score. Higher scores indicate poorer sleep quality.

Lumbar spine range of motionChange from Baseline (pre-treatment) to after completion of 3 months of aerobic exercise training (post-treatment)

Lumbar spine range of motion into forward, backward, and side bending will be assessed with two inclinometers or a tape measure. subjects will

Pain Sensitivity (CPM test)Change from Baseline (pre-treatment) to after completion of 3 months of aerobic exercise training (post-treatment)

Measure of the functionality of descending inhibitory pain pathways with use of pressure algometry.

Beck Depression InventoryChange from Baseline (pre-treatment) to after completion of 3 months of aerobic exercise training (post-treatment)

Beck depression questionnaire contains 21 multiple-choice depression related questions on a scale value of 0 to 3. Higher scores indicate greater depressive symptoms.

Fear Avoidance Belief QuestionnaireChange from Baseline (pre-treatment) to after completion of 3 months of aerobic exercise training (post-treatment)

The survey has items related to fear about physical and work activities. Each item is scored from 0-6 points, with higher number indicating increased fear of activity or work.

Pain Catastrophizing ScaleChange from Baseline (pre-treatment) to after completion of 3 months of aerobic exercise training (post-treatment)

PCS is a validated 13--item scale with questions related to catastrophizing behavior. Total score is 52 with higher scores indicating greater catastrophic thoughts.

Beck Anxiety InventoryChange from Baseline (pre-treatment) to after completion of 3 months of aerobic exercise training (post-treatment)

Beck anxiety questionnaire contains 21 multiple-choice questions, each score 0 (not al all) to 3 (severely). Higher scores indicate greater anxiety symptoms.
