Scrambler Therapy in the Treatment of Chronic Chemotherapy-Induced Peripheral Neuropathy

The purpose of this study is to see if Scrambler Therapy with the Calmare MC5-A machine will relieve chemotherapy induced peripheral neuropathy (CIPN). Scrambler Therapy is a method of pain relief given with common electrocardiography (ECG) skin electrodes. The electrodes are placed on the body in pairs, and the Scrambler Therapy machine directs electrical signals across the field to simulate non-pain information. Based on other studies, we think that we relieve pain with the Scrambler therapy device, but it has not been tested in a setting such as this one. This means that some of the pain relief could be due to placebo effect, or the CIPN pain going away on its own. In this study we want to compare the Scrambler Therapy with the sham therapy (the therapy that does not use the electrical signals). We hope that this study will help us determine if the Scrambler device really helps patients with CIPN. Cancer patients with chronic, chemotherapy-related pain of 4 or more (on a 0-10 scale) for at least 3 months may be eligible to join this study.
