Is there any scholarly research available on the power balance bands?

Not necessarily how they work or allegedly work but studies that have a number of people tested with and/or without the band and see if there is some type of statistical significance. I am a graduate student who will do a study on these but I cannot find a speck of accredited research. Anything would be helpful, even if its another seemingly unlikely balance aid or how supposed holograms work on the body in other ways/studies. ANYTHING would be helpful. Thank you in advance.
