Low-Level Laser Therapy as a Non-Invasive Approach for Body Contouring: A Randomized, Controlled Study

摘要: Background and Objective: Transmission electron microscopic images have demonstrated the formation of transitory pores in adipocyte cell membranes followed by collapse adipose cells subsequent to laser irradiation 635 nm. The objective is evaluate application a nm 17.5 mW exit power per multiple diode for non-invasive body contouring waist, hips, thighs. Study Design/Patients Methods: Double-blind, randomized, placebo-controlled trial 2-week noninvasive treatment conducted from May 2007 June 2008 across multiple-private practice sites United States America. Sixty-seven volunteers between ages 18–65 with mass index (BMI) 25 30 kg/m 2 who satisfied set inclusion criteria participated. Eight 67 subjects did not circumference measurements recorded at post-procedure measurement point. Participants were randomly assigned receive low-level treatments or matching sham three times week weeks. Reduction total combined inches hip bilateral thighs baseline completion procedure administration phase was assessed. Results: group an overall reduction all � 3.51 in. (P < 0.001) compared control revealed 0.684 0.071745). Test participants 0.98 0.0001) 1.05 0.01) hip, 0.85 0.65 right left weeks (end treatment). At post-procedure, test gain 0.31 collectively sites. Conclusion: These data suggest that therapy can reduce specifically treated regions. Lasers Surg. Med. 41:799– 809, 2009. 2009 Wiley-Liss, Inc.
