Abstract
Purpose : The Purpose of this study was to compare muscle activation and foot pressure on baby carrier and sling for baby care. Methods : Thirty one women subjects (mean age 23.2 years) participated in four static conditions : unloaded quite standing, carrying an anterior baby carrier, carrying a posterior baby carrier, and sling. The baby carrier and sling were loaded with baby model that filled 7.6kg loads. Surface electromyography was used to measure activity in the internal oblique, T4, L3, L5 paraspinal muscle, vastus medialis, biceps femoris, tibialis anterior, and gastrocnemius for four conditions. And foot pressure was measured by using MatScan system(Tekscan, USA). Results : The activation of Biceps femoris, T4, L3, and L5 paraspinal muscle were significant differences(p<.05), but other muscles were no significant differences in four conditions(p>.05). Right foot contact area and peak pressure of right mid foot area were significant differences in four conditions(p<.05). Conclusion : The results of this study indicate that the use of baby carrier of sling for baby care were influenced postural responses of young women. Further work is recommended to find out the influences of various assistive devices for baby care.
