Gait Adaptations Under Cognitive and Motor Dual-Task Conditions

Abstract

Modern walking often involves secondary tasks that may increase fall risk, especially in older adults. About one-third of adults aged 65+ fall annually, with dual-tasking further elevating this risk. This study examines how cognitive and motor dual-tasks affect gait variability. Ten healthy young adults completed baseline and three dual-task conditions: (1) walking with a Stroop test, (2) walking while carrying a tray with water, and (3) both tasks combined. Gait parameters—including step length, step width, stride length, and double support time—were analyzed. Significant alterations were observed with P-values of 0.0019 (right step length), 0.004 (step width), 0.0007 (stride length), and 0.0477 (double support time), indicating increased gait variability. These results suggest dual-tasking disrupts gait stability and highlight the clinical value of dual-task training for improving motor-cognitive integration and reducing fall risk.
