Effect of cognitive dual task on body balance
摘要
Abstract
Objective :To compare the differences among single task ,music dual task and mental arithmetic dual task on body balance .Methods :The balance function (standing on one leg in eyes-open and eyes-closed situations) of 25 normal university students was recorded .Subjects were tested in three different conditions :single task ,dual task 1 (music group) and dual task 2 (mental arithmetic group) .The maximum and average deviation of center of pressure in both frontal and vertical plane and peripheral area of center of pressure were collected .Results :There was no significant difference in the three tasks tested between the left and right leg conditions .The data of maximum deviation of center of pressure in eyes-open situations were all less than in eyes-close situations in single task test , dual task 1 and dual task 2 (P<0 .05) .No significant difference was found between single task and dual task 1 ,but maximum deviation of center of pressure in dual task 2 was increased significantly ,and that in the anteroposterior ax-is ,coronal axis and the peripheral area in the dual task 1 in eyes-open situation as compared with single task (P<0 .05) .No increase was observed in eyes-closed situation .Conclusion :Visual system may play an important role in keeping balance of human bodies ,but it is disturbed by cognitive load and distribution .关键词
