In Reply We thank Cury et al for their interest in our article.1 In our study, we included any type of pain that the patients reported, irrespective of its presumptive causes, which is more relevant to clinical situations than excluding pains that may have causes other than Parkinson disease (PD). As a result, in contrast to the study by Cury et al,2 the prevalence of pain increased during the 8-year follow-up primarily owing to the development of new pain, despite the improvement in the severity of pain. However, our short-term results showed that the prevalence of pain decreased at 2 years after subthalamic nucleus deep brain stimulation (STN DBS) compared with baseline as shown in Figure 1B of our article,1 which is in line with Cury et al.
