Trial Outcomes & Findings for Study of Low Level Laser Therapy to Treat Low Back Pain (NCT NCT01835756)

Last Updated: 2016-02-02

Results Overview

Primary outcome success for an individual subject was defined as a 30% or greater change (decrease) in VAS pain score at 4 months post-procedure relative to baseline. The VAS is a straight line scale that is marked on one end with a '0' for 'no pain' and at the other end with '100' for 'worse pain imaginable.' A higher score indicates a greater level of pain, and a lower score indicates a lower level of pain. A negative (-) percent change in VAS rating indicates a decrease in pain level and is positive for individual subject success. A positive (+) percent change indicates an increase in pain level and is negative for individual subject success. Overall study success was defined as a 35% or greater difference in the proportion of individual primary outcome successes in each treatment group, in favor of the active treatment group.

Measure	Erchonia MLS The Erchonia MLS contains 10 independent diodes, each emitting 17 milliwatts (mW), 635 nanometers (nm) of red laser light. It is applied to the lower back and hips area for 30 minutes per treatment administration, 6 times across 3 weeks, 2 times per week.	Placebo Laser The Placebo Laser has the same appearance as the Erchonia MLS but does not emit any therapeutic light.

SECONDARY outcome

Timeframe: Baseline and 4 Months

The VAS is a straight line scale that is marked on one end with a '0' for 'no pain' and at the other end with '100' for 'worse pain imaginable.' A higher score on the VAS indicates a greater level of pain, and a lower score indicates a lower level of pain.A decrease in the VAS pain rating indicates a reduction in low back pain and is positive for study success. An increase in the VAS pain rating indicates a worsening of low back pain and is negative for study success. The mean change in low back pain score recorded on the Visual Analog Scale (VAS) from baseline to 4 months post-procedure was calculated for each treatment group.

SECONDARY outcome

Timeframe: 4 Months

At study endpoint, the subject was asked to rate how satisfied he or she was with any overall change in low back pain attained following the procedure administration phase with the Erchonia MLS Laser, using the following five-point scale: Very Satisfied Somewhat Satisfied Neither Satisfied nor Dissatisfied Not Very Satisfied Not at All Satisfied Results are reported as the number of subjects who reported being 'Very Satisfied' or 'Somewhat Satisfied' with the study outcome.
