Background And ObjectivesParkinson disease may present difficulties in performing dual tasks. The use of dual tasks during training can improve different abilities. Therefore, the objective of this study is creating a protocol, based on standard protocol items recommendations for interventional trials compliant, for a clinical trial study conduct, review, reporting, and interpretation. This protocol will provide the framework and a guide to a randomized double-blind study, that will be conducted to assess the influence of a cycling exercise program combined with a cognitive task, on cognitive and physical Parkinson disease aspects.MethodsDesigned a protocol for a double-blind randomized study, where participants will perform a dual tasks intervention with cycling and a cognitive task. The revised version of the unified Parkinson disease rating scale, the Parkinson disease questionnaire, the timed up and go Test, the 30 seconds chair sit to stand test, the Stroop and the trail making test will be used to measure outcomes.DiscussionResearch in Parkinson disease suggests that an improvement of motor and cognitive functions of Parkinson disease patients can be achieved by modifying different motor and cognitive pathways. The results of the present study will yield findings on both the physical and cognitive response to an intervention that combines a cognitive task with a motor task in Parkinson disease patients and will be essential tool for a better conducting of the clinical trial study.Copyright © 2022 the Author(s).
