Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Spinal Manipulation
Subjects with subacute low back pain. Subjects will receive 6 treatments of Spinal Manipulation (SM) over 2 consecutive weeks
Other: Spinal Manipulation
The subject will be asked to lay down and bend in a specific way. The clinician will apply force to certain areas to manipulate the spine.
Placebo Comparator: Placebo Spinal Manipulation
Subjects with subacute low back pain. Subjects will be asked to visit the clinic for 6 times. The clinician will go through SM motions but the spine will not actually be manipulated.
Other: Placebo Spinal Manipulation
The subject will be asked to lay down and bend in a specific way. The clinician will apply force to certain areas to simulate manipulating the spine.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Pain Threshold measured using Pain Pressure Threshold (PPT) testing
Time Frame: Change from Pre-treatment to Post-treatment, 2 Weeks
Outcome will be measured using Pain Pressure Threshold (PPT) testing. Pressure will be applied to subjects using a digital algometer. Three trials for PPT will be done and the mean value will be calculated.
Change from Pre-treatment to Post-treatment, 2 Weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in function measured using the Oswestry Disability Index (ODI)
Time Frame: Change from Baseline to Week 2
Outcome will be measured using the Oswestry Disability Index (ODI). Subjects answer to questions. Their responses indicate no impact to great impact. Scores for each question range from 0 to 5. Total score for the ODI is 50. The higher the score, the greater level of disability/function.
Change from Baseline to Week 2
Change in Low Back Pain measured using the Numerical Pain Rating Scale (NPRS)
Time Frame: Change from Baseline to Week 2
Outcome will be measured using the Numerical Pain Rating Scale (NPRS). Pain intensity will be assessed using an 11-point scale. Scores on the scale range from "0" indicating no pain, "1" slight pain, and "10" strongest imaginable pain.
Change from Baseline to Week 2
Change in Fear Avoidance Beliefs Questionnaire (FABQ)
Time Frame: Change from Baseline to Week 2
The FABQ is completed by the subject. It determines the level of fear and avoidance about work and physical activity. The measure is comprised of two subscales: a four item physical activity subscale (FABQ-W), and a seven-item work subscale (FABQ-W). An elevated FABQ score is predictive of the development of chronic disability in low back pain (LBP) patients.
Change from Baseline to Week 2
