For the purpose of this study, the Reparel Sleeve will be evaluated against a placebo sleeve of similar feel, texture, and look. The indication is that due to its technology, the Reparel sleeve will allow for the ability to reflect energy using a blend of semi-conductors grounded to nanoparticles interwoven between fibers of the sleeve. Thermal energy is then absorbed from the patient thus activating electrons on the nanoparticles and releasing photonic energy directed at tissues within the surrounding area7. This photostimulation is expected to alleviate pain and inflammation while promoting wound healing as well as tissue regeneration.

Generic sleeve used as a placebo. This placebo will have a similar feel, texture, and look with no additional technology.
