Standard care
Isolated Lumbar Resistance Exercise Program

Arm Description
Subjects will receive normal medical care and follow up during the four month study period if assigned to this group.
Lumbar extension exercise protocol to increase strength and reduce pain.
Training protocol for 1 set for each exercise: leg press, leg curl, leg extension, chest press, seated row, overhead press, triceps dip, biceps curl, calf press and abdominal curl
Outcomes
Primary Outcome Measures
10 centimeter Visual Analog Scale (VAS); Change from Baseline at 1, 2, 3 and 4 Months
The VAS scale will range from 0-10 cm, where a rating of "0" reflects no pain, and a "10" rating represents "worst pain imaginable. Subjects will complete the VAS at the indicated time intervals to document any change in their pain levels.
Tampa Scale of Kinesiophobia (TSK); Change from Baseline at 1, 2, 3 and 4 Months
Fear avoidance beliefs will be measured using the 11 item TSK. Subjects will complete the TSK at the indicated time intervals to document any change in their fear avoidance beliefs.
Fear-Avoidance Beliefs Questionnaire (FABQ); Change from Baseline at 1, 2, 3 and 4 Months
The FABQ is a tool based on theories of fear and avoidance behavior and focuses specifically on beliefs about how physical activity and work affect low back pain. Subjects will complete the FABQ at the indicated time intervals to document any change in their fear and avoidance behavior.
Pain Catastrophizing Scale (PCS); Change from Baseline at 1, 2, 3 and 4 Months
The PCS will be used to assess the effect of the chronic back pain on rumination on pain symptoms and helplessness. Subjects will complete the PCS at the indicated time intervals to document any change in their thoughts of their pain symptoms.
Modified Oswestry Disability Index (ODI); Change from Baseline at 1, 2, 3 and 4 Months
The ODI is responsive to intervention treatments for low back pain, is reliable, and corresponds well with several global patient disability measures. Subjects will complete the ODI at the indicated time intervals to document any change in their low back pain.
Roland Disability Survey (RDS); Change from Baseline at 1, 2, 3 and 4 Months
The RDS assesses physical disability and mental function with low back pain; this survey is sensitive to treatment interventions, and is reproducible and consistent and correlated well with other global ratings and disability measures. Subjects will complete the RDS at the indicated time intervals to document any change in their physical disability and mental function with their low back pain.
Secondary Outcome Measures
Graded Treadmill Exercise Test; Change from Baseline at 4 Months
Maximal aerobic fitness, or oxygen consumption (VO2max) will be determined using a walking symptom-limited graded exercise test. Subjects will complete the exercise test at the indicated time intervals to document any change in their aerobic fitness.
Chair Rise Time, Stair Climb Time and Gait Assessment; Change from Baseline at 4 Months
Chair rise time will be measured as the participant moves from a sitting to a full standing position. The time to walk up one flight of stairs will be measured by having the participants walk up one flight of stairs consisting of 12 steps as quickly as possible. Gait will be assessed by having the participants walk across a 26' portable walkway. Subjects will complete these motions at the indicated time intervals to document any change.
7-day Pedometer Test; Change from Baseline at 4 Months
Community ambulation will be estimated using a 7-day pedometer test in which participants will wear a StepWatch® step activity monitor. Subjects will complete this test at the indicated time intervals to document any change in their ambulation.
Ultrasound Muscle Thickness; Change from Baseline at 4 Months
The ultrasound technique that will be used to capture muscle thickness changes in the paraspinal and multifidus muscles. Subjects will be tested at the indicated time intervals to document any change.
Muscle Strength; Change from Baseline at 1, 2, 3 and 4 Months
Assessments of strength (1 repetition maximum, 1-RM) will be determined for all muscle groups trained. Subjects will be assessed at the indicated time intervals to document any change.
