Trial Outcomes & Findings for Photobiomodulation Therapy Using the Realief Therapy System for the Treatment of Chemotherapy-associated Peripheral Neuropathy (NCT NCT02000908)

NCT ID: NCT02000908

Last Updated: 2019-02-11

Results Overview

For each patient, we will compute the difference between the total neuropathy score at 8 weeks (the end of treatment) and the total neuropathy score at the time of randomization. The mean change in score for the experimental group patients will be compared to the mean change in score for the control group patients using a two-sample t-test. Scale scoring is 0-\<20 0 being no pain \<20 =severe

Realief Therapy
Each patient will be given 15-18 treatments depending on response of 30-minute duration of photobiomodulation with the Realief Therapy system, scheduled every three times weekly for 5-6 weeks. The treatments will include laser exposure of any or all of 27 differentiated areas of the legs, feet, cervical spine region and lumbar spine region, for durations of 3 to 30 minutes, based on the symptom presentation at the time. Power densities will vary from 5 to 12 watts, based on the symptom presentations through the course of therapy. photobiomodulation: The photobiomodulation delivered by Realief Therapy involves amplitude wavelength light delivered by a class IV therapeutic laser.
Sham Treatment
The placebo group will receive sham treatment, during which a heat probe will be guided over both lower extremities over a period of 30 minutes, consistent with the treatment arm. The laser device will be activated during the treatment so that the visual and auditory environment prior to therapy will be the same for both treatment and sham control. After 8 weeks of sham treatment the subjects in this arm will be offered the photobiomodulation combined with physiotherapy. photobiomodulation: The photobiomodulation delivered by Realief Therapy involves amplitude wavelength light delivered by a class IV therapeutic laser. Sham treatment: All patients in sham treatment arm cross over to laser therapy followed by physiotherapy Physiotherapy: Chiropractic massage and lymphedema treatment
