The purpose of our study was to develop an easy-to-use application, for touchscreen devices, able to quantify the degree of upper limb movement impairment in patients with severe Friedreich’s ataxia. The APP, which we named “Twelve-Red-Squares App-Coo-Test” (12-RSACT), assesses the upper limb ataxia by measuring the test execution time. 12-RSACT is an inexpensive test and is easy to use, which can be administered quickly. Therefore, 12-RSACT is a promising tool to assess the upper limb ataxia in FRDA patients and even those with severe diseases.
