Dual-task activities impact the gait kinematics of both amputated and healthy participants similarly

Abstract

Introduction: Gait is the motor task most impacted by amputation, requiring several physical and cognitive adaptations. The interaction between cognition and movement can be validly assessed through dual-tasks analysis. Objective: To analyze the kinematics of single and dual-motor tasks of participants with transfemoral amputation and compare it with healthy participants. Methods: This is a comparative cross-sectional study in which 14 participants in the transfemoral amputee group and 14 non-amputee participants attended the Gait Laboratory of the Clinical Center of the Universidade de Caxias do Sul to perform cognitive and motor activities tests. Speed, cadence, stride width, stride length, step length and step time were analyzed. Results: participants in the transfemoral amputee group presented impaired gait kinematic parameters when compared to non-amputates during single and dual-tasks. Both groups showed a similar percentage decrease in performance on the dual-task compared to the single task. Conclusion: There is a distinction observed in the gait patterns and parameters of both groups, as evidenced in both the simple gait assessment and the dual-task evaluation. The primary finding of our study suggests that changes in gait kinematics appear to be exacerbated by dual-tasking rather than solely by amputation.
