Resumen
El texto original del estudio, en el idioma en que se publicó.
Background
Physiotherapy has a very important role in the maintenance of the integumentary system integrity. There is very few evidence in humans. Nevertheless, there are some studies about tissue regeneration using low-level laser therapy (LLLT).
Aim
To analyze the effectiveness of LLLT on scar tissue.
Methods
Seventeen volunteers were stratified by age of their scars, and then randomly assigned to an experimental group (EG) - n = 9 - and a placebo group (PG) - n = 8. Fifteen sessions were conducted to both the groups thrice a week. However, in the PG, the laser device was switched off. Scars' thickness, length, width, macroscopic aspect, pain threshold, pain perception, and itching were measured.
Results
After 5 weeks, there were no statistically significant differences in any variable between both the groups. However, analyzing independently each group, EG showed a significant improvement in macroscopic aspect (p = 0.003) using LLLT. Taking into account the scars' age, LLLT showed a tendency to decrease older scars' thickness in EG.
Conclusion
The intervention with LLLT appears to have a positive effect on the macroscopic scars' appearance, and on old scars' thickness, in the studied sample. However, it cannot be said for sure that LLLT has influence on scar tissue.
