Heterogeneity of Tasks and Outcome Measures in Dual Tasking Studies in Children With Cerebral Palsy: A Scoping Review

Abstract

Abstract Objective The aims of this scoping review are to examine the available literature regarding dual tasking in children with cerebral palsy (CP) and to identify and categorize both the motor and cognitive tasks and outcome measures used primarily through the International Classification of Functioning, Disability, and Health model. Methods Five electronic databases were searched. Studies were included if they: (1) were published in English; (2) included at least 1 group of children or adolescents with a diagnosis of CP; (3) assessed dual tasking as part of the study; (4) reported the method for performing the dual task; and (5) reported the outcome measures utilized. Results Twenty-three studies with 439 children with CP were included. All studies utilized motor activities as the primary task, including walking, balance, and a functional transition. Motor secondary tasks occurred in 10 studies, cognitive secondary tasks in 12 studies, and 1 study used both. Forty-one outcome measures over 23 studies assessed the body structure and function domain, 7 measures over 6 studies assessed activity limitations, and 2 outcomes over 2 studies assessed participation. Conclusion The 23 included studies demonstrated heterogeneity in the age and function of participants, secondary tasks, and outcome measures. Future studies on dual tasking in children with CP should consider the difficulty of the primary motor or cognitive task and compare secondary tasks to establish this contribution to motor performance. Studies should incorporate activity and participation measures to assess meaningful functional outcomes. Impact Children with CP experience challenges when exposed to dual task situations. This scoping review highlights the importance of considering multiple factors when designing dual tasking studies involving children with CP to facilitate results translation, improved participation, and enhanced function. Similarly, studies should utilize activity and participation outcomes to assess quality of life.
