Blinding Techniques in Randomized Controlled Trials of Laser Therapy: An Overview and Possible Solution

Ian Relf, Roberta Chow, Marie Pirotta
2008 Evidence-Based Complementary and Alternative Medicine  
Many of the trials used blinding methods that rely on staff cooperation and are therefore open to interference or bias. This indicates significant deficiencies in laser trial methodology.  ...  Low-level laser therapy has evidence accumulating about its effectiveness in a variety of medical conditions. We reviewed 51 double blind randomized controlled trials (RCTs) of laser treatment.  ...  Acknowledgments We would like to thank Dr Alan Harvey who built the DBL Trial Laser machine with assistance from the Royal Melbourne Institute of Technology and Acupak Pty. Ltd. Melbourne, Australia.  ...
