Coordination between motor and cognitive tasks in dual task gait

Dual Task (DT) paradigms are frequently used by researchers and clinicians to examine the integrity of motor processes in many movement disorders. However, mechanism this interaction is not fully understood. Therefore, aim study was within-stride interactions between cognitive during dual task gait (DT). Do healthy young adults coordinate with secondary processing? If so, processing capability associated coordination observed? Nineteen walked for two minutes on a motorized treadmill whilst counting backwards sevens from three-digit numbers. The calculation verbalizations parameters were assessed across six phases cycle. Mid verbalization time points (VERMid) as high compared end (VEREnd) low processing. VERMid VEREnd did systematically occur any phase 10/19 9/19 participants showed non-random distributions respectively (p < 0.01), indicating that these walkers coordinated task. Analysis subgroups Verbalization Coordinators Non-Coordinators slower response durations (VRD) Non-Coordinators, found tasks more demanding. No differences VRD Non-Coordinators. It some but all DT gait. When demands high, may be use studying clinical conditions where attentional cognition performance breaks down.
