Abstract

This study tried to show an approach for joints process healing based on using of low level laser therapy (LLLT), in order to enhance the healing rate. The effect is not thermal, but rather related to photochemical reactions in the cells.
This study included 26 patients with low back pain (LBP) in range of 20-50 years old were randomly divided to the laser treatment group and laser placebo group (control group). Both of two groups were treated twice weekly for 6 weeks. The treated group exposed group to pulse infrared with diode laser (BEAM 3K00) with 904nm wavelength and 230mJ (energy) for one point, and was irradiated on the vertebral column. The same process was performed on control group but with off laser. The laser placebo group did not complete their treatment because there was no improvement or decrease pain. The treated group divided into three subgroups according to the treatment period: the first showed improvement and decrease pain where dispersed to (4) in end of the three-week treatment, and (4) in a five-week treatment, and (5) valuable six weeks treatment. Visual analogue scale (VAS), Schober test and Roland Disability Questionnaire (RDQ) were used in the clinical and functional evaluations pre and post therapeutic periods. Significant improvements were noted in all groups with respect to all outcome parameters, in comparison to placebo laser group. Efficacies of treatment were evaluated using pain relief between treated groups by the statistical significance of the differences between the three feature sets for the LBP was tested with a Bonferroni corrected analysis of variance (ANOVA) test with a significance level of 0.05. Statistically significant differences were found in all outcomes measured (p<0.05).
