The Charcot-Marie-Tooth Pediatric Scale (CMTPedS) is a validated and change-sensitive tool for assessing the severity of neuropathy in children and adolescents between 3 and 20 years of age. The aim of this article is to translate and validate a Spanish version of the CMTPedS in order to disseminate its use in Spanish-speaking countries. The process used to translate the CMTPedS into Spanish was the reverse parallel translation method based on the principles of good practice for translation and the cultural adaptation process of the Food and Drug Administration Guidelines. A direct translation of the original source of the CMTPedS into Spanish was performed first and reviewed by experts in Charcot-Marie-Tooth (CMT) disease trained in the use of the CMTPedS tool. The Spanish version was then translated back into English by a linguist specialised in translation. The preliminary Spanish version of the CMTPedS was evaluated in 18 children with CMT aged 6-20 years (mean: 13.27). The scale was well tolerated and easy for children to understand and easy for clinicians to apply. None of the patients had any difficulty completing the scale. The Spanish version of the CMTPedS can be used for monitoring and conducting clinical trials in the Spanish population and in Spanish-speaking countries.
