We identified that oncological treatments in general (chemotherapies, immunotherapies and radiotherapies) frequently cause peripheral neuropathy, including cramps, characterized by excess protons due to metabolic and neuronal factors, such as sudden changes in pH, uremia and aspects that affect neuromotor functions. Such situations and others like them are often neglected in treatment, which naturally concerns itself with the main problem: Cancer. Sometimes toxic solutions are implemented that have comorbid side effects, such as duloxetine (standard treatment). Based on monitoring of cancer patients who used the non-toxic product, called “Magicramp® electrostatic Charge Reduction Cushion” (MeCRC), approved in europe more than 10 years ago, we carried out a controlled test in Brazil. In this clinical trial, we hypothesized that reducing excessive ionic charges (electrostatic charge), which is one of the side effects often described in the literature as “Chemotherapy-Induced Peripheral Neuropathy” (CIPN), would decrease or eliminate cramping, under the hypothesis that such elimination would prevent or attenuate muscular vulnerability to action impulses, and increase the power of relaxation through the same mechanism. In this double-blind and randomized clinical trial, 40 (forty) adult patients with muscle cramps caused by oncological treatments were tested, evaluating the degree of efficiency of the product that aims to reduce muscle cramps, by eliminating and/or reducing excess loads electrostatic ionic. Data from the clinical research conducted in this study are available online at https://***/10.7910/DVN/QUS94U.
