Abstract
Objective: To determine changes in gait pattern during multi-tasking in healthy young individuals using GAITRite system.
Methodology: In this comparative cross-sectional study, three tasks were performed by 30 subjects on GAITRite system. The first was a single task of strolling in order to approach a ﬁxed mark, second was dual task typing a message while strolling in order to approach a ﬁxed mark and third was a triple task of typing a message and answering a question asked by investigator while walking toward a ﬁxed target.
Results: The gait parameters as velocity, cadence, stride length and step length decreased in triple task. Velocity and cadence recorded in single task, dual task and triple task was 108.28±15.16 cm/s, 88.33±19.61 cm/s, 92.02±19.50 cm/s and 102.85±9.95, 92.23±13.98, 93.29±13.70, respectively. The mean stride length and step length recorded in single task, dual task and triple task was 126.88±10.15 cm, 114.14±14.30 cm, 116.14±20.49 cm and 63.15±4.78 cm, 57.12±7.30 cm, 58.89±7.71 cm, respectively. The mean double support recorded in single task, dual task and triple task was 22.59±4.82, 26.15±4.40, 25.19±5.06, respectively. Significant difference was found between single, double and triple task (p<0.05) of all variables.
Conclusion: Changes occurred in gait parameters in healthy individuals while performing different single, dual and triple tasks during walking.

Key words: Gait, Multitasking, Dual task, GAITRite System.
