Effects of Different Carrying Bag Position on the Muscle Activation of Neck and Lumbar During Walking in Young Women
초록
영어
This study aimed to compare the activity levels of the neck extensor, upper trapezius, and erector spinae muscles according to walking posture while carrying three different types of bags. Electromyogram signals were measured in 18 women with chronic neck and lumbar pain as they walked back and forth five times a total of 10m. In the first condition, they carried a backpack on both shoulders. In the second condition, they carried a tote bag on one shoulder. In the third condition, they carried a tote bag on one forearm. Significant differences were recorded by repeated measures by one-way analysis of variance. Carrying a bag on one shoulder and the forearm significantly increased the activity levelsof the ipsilateral neck extensor, upper trapezius, and contralateral erector spinae muscles as compared with that noted when carrying a backpack on both shoulders (p<.05). Carrying a bag on one forearm also significantly increased the activity levels of the ipsilateral neck extensor and upper trapezius muscles as compared with that noted when carrying a bag on one shoulder (p<.05). Carrying a bag on one forearm increases the activity levelsof left and right neck extensor, upper trapezius, and erector spinae muscles in a more unbalanced manner than with the other bag-carrying methods. Therefore, women should avoid this bag-carrying method.
