• Conditions: Low Back Pain

• Registration Number: NCT02409797
• Lead Sponsor: Palmer College of Chiropractic

Brief Summary

The INSIGHT pilot study will measure forces applied by a doctor of chiropractic (DC) during the delivery of a specific, manually based chiropractic treatment for participants with low back pain.

Detailed Description

Low back pain (LBP) is a well-recognized health problem. One common manual therapy available for the treatment of LBP is spinal manipulation (SM), which can be separated into 2 categories: High-Velocity Low-Amplitude (thrust) and Low-Velocity (non-thrust) SM according to their force-delivery profiles. One commonly utilized non-thrust SM technique is the Flexion-Distraction procedure. Several studies have reported manually applied forces during thrust SM; however, the forces used during non-thrust SM, specifically those used with Flexion-Distraction treatment are still unknown. The results of this pilot study will provide preliminary information on treatment forces and sample size justification for future full-scale trials, while also ascertaining the feasibility of the study protocol and patient recruitment methods for such trials.

Arm && Interventions

Group	Intervention	Description
Flexion-Distraction spinal manipulation	Flexion-Distraction (non-thrust) spinal manipulation	Participants will receive Flexion-Distraction treatment from a licensed doctor of chiropractic. During the procedure the participant lies prone on a specially designed treatment table. The table is equipped with a movable lower body section, which can be directed by the study doctor to lower the participants legs, move them from side to side, or in a traction motion. Table movements can occur in combination with other motions, depending on the diagnosis and characteristics specific to the participant's condition. During this procedure, the doctor will also touch the lower or upper part of the participants back or neck with their hands to direct treatment toward specific spinal regions.

Primary Outcome Measures

Name	Time	Method
Traction forces	Baseline and 2 weeks	We will measure traction forces delivered to the participant by the clinician during all study visits over a 2-week time period. Traction forces will be summarized descriptively with means and standard deviations. Primary outcomes will compare changes in traction forces between the baseline and final treatment visit at 2 weeks.

Secondary Outcome Measures

Name	Time	Method
Pain Visual Analog Scale (VAS)	Baseline and 2 weeks	The Visual Analog Scale (VAS) will be used to assess the participant's current back pain level and their average back pain levels over the past 24hrs and week. Participants will be asked to rate their level of pain on a 100 millimeter continuum horizontal scale with no pain and worst imaginable pain anchors.
