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.

Objective : The purpose of this study was to identify the characteristics of a single-subject research study and qualitative levels in which occupational therapy interventions were performed on children with cerebral palsy. Methods : This study targeted papers, published in Research Information Sharing Service (RISS), National Digital Science Library (NDSL), Koreanstudies Information Service System (KISS), and E-article from May 20 to 29, 2022. The search terms were 'cerebral palsy' AND 'single subject research design' OR 'individual subject study'. Eleven papers, were finally selected and analyzed. Results : Most of the studies were medium in methodological quality, and the subjects were pre-school age and spastic hemiplegia. Among the single-subject designs, intervention-removal designs were the most common, and among them, ABA designs were the most common. Interventions included assistive devices, constraint-induced therapy, neurodevelopmental therapy, and sensory integration therapy were 2, and upper extremity exercise, interactive metronome, and CO-OP were 1. Dependent variables were measured with 2 to 4 measurement tools, Significant improvements were found in postural control ability, gait and balance, hand function, and upper extremity function. Conclusion : This study confirmed that it is helpful to apply cerebral palsy occupational therapy by presenting the characteristics of cerebral palsy, intervention sessions and effects, measurement tools and methodological quality levels.
