Pulsed High Intensity Laser Versus Extracorporeal Shockwave Therapy on Hypertrophic Scar Post Burn

The high-intensity laser therapy (HILT), which involves laser radiation with high-intensity, is a kind of novel and powerful . The HILT possesses its own photomechanical, photothermal, and the photo-chemical properties.

Extracorporeal shockwave therapy is an acoustic wave that mechanically disrupts tissue by cavitation.Shock waves develop microscopic injuries in scar tissue and break down collagen fibers which lead to scar remodelin .The patient is positioned in a comfortable position. The scar site is prepared with contact gel to conduct the shock waves, 30-50 shocks/cm2 , with an energy flux density of 0.25mJ/mm2 and a frequency of 6Hz. Each treatment region is covered with 2500 to 3000 impulses with an average session time of 10-15min .
