Pain is one of the most frequent non-motor symptoms associated with Parkinson's disease (PD) and it has a great impact on patient's quality of life. Thus, its quantitative evaluation is critical in establishing therapeutic evidence. The King's Parkinson's Disease Pain Scale (KPPS) was introduced as a scale of pain specific to PD in 2015. As a follow-up to the evaluator-based KPPS, the patient-based questionnaire, the King's Parkinson's Disease Pain Questionnaire (KPPQ), was introduced in 2018. We developed a linguistically validated Japanese version of the KPPS and KPPQ, and the process of its construction is reported in this study.
