[OBJECTIVES] The purpose of the study was to investigate weight distribution, posture alignment, and gait parameters while a mother was transporting a baby with varied baby carriers during gait. [METHODS] Five mothers transported their babies with three different baby carriers(baby carrier, hipseat carrier, & hipseat) and carried babies with their arms. Ten cameras, marker sets, and forceplatforms were used to get the kinematic, force, and gait parameters. [RESULTS] The hipseat showed that the range of motion in the hip joint was small, the step length and stride length was short, and the gait velocity was slow. Mothers carried their babies with arms showed that lower in the trunk flexion angle, larger in the stride length, and faster in the gait velocity were than any other baby carriers. [CONCLUSIONS] The baby carrier is important for infant's growth and care, but there is lack of product appropriateness, use, and scientific basis. Therefore, further study is needed to investigate varied performance with transporting a baby with baby carriers.

Background : Methods of wearing a baby carrier have suggested; however, there have been no studies suggesting ideal ways. Objective : To investigate muscular fatigue and balance of the waist during baby carrier are worn on the front, the side, and the back of the body. Design: Randomized controlled clinical trial (single blind) Methods : The subjects of this study were 20 healthy men and women in their 20s, who underwent tests of muscular fatigue and balance of the waist bones based on types of wearing baby carrier. Electromyogram (EMG) patches were attached to the L2 and the L4 for testing muscular fatigue, while a device for measuring proprioceptive senses was used to assess balance ability. The measurements were performed before wearing the baby carrier and after 30 minutes of normal walking. The methods of wearing the baby carrier included wearing on the front, the side, and the back of the body. Results : The time taken to adjust the balance was shorter than other types of wearing during the baby carrier were worn on the side, and the ratio of lumbar flexion and relaxation was shown insignificant. Conclusions : These results suggested that wearing the carriers on the side was most effective on reducing fatigue and enhancing balance ability of the waist.

Purpose:The purpose of this study was to evaluate the effects of muscle activation of neck, lumbar and low limb by using baby carrier with arms during walking. Methods:Twenty healthy and young females who brought up infants and had no musculoskeletal disorders of neck, lumbar and low limb were recruited for this study. They were instructed to perform muscle activation of neck, lumbar and low limb using the baby carrier with and without arms during walking. ProComp infinitiTM (Thought Technology Ltd., Canada) was used to measure the muscle activity of neck, lumbar and lower extremity muscles. Results:Activation of neck paraspinalis muscle was significantly increased using baby carrier with arms and there was a significant increase on erector spinae muscle activation by using anterior baby carrier. Conclusion:These results indicate that the muscle activation was changed by arms assist and the position of using baby carrier. Therefore, it could be considered relationship of muscle activation and musculoskeletal demage as carrying baby.

This study aimed to compare the effects of wearing and not wearing a baby carrier on diaphragm movement, thoracic mobility, and forced vital capacity (FVC). A baby carrier is a device used to hold a baby weighing about 3 to 8 kg or more for at least 6 months before it starts moving on its own or during the parenting period. Wearing a baby carrier for a long time increases pressure on the shoulders, chest, and abdomen, causing muscle fatigue. The current study comprised a cross-sectional design and randomized controlled trial including 20 healthy adult males between the ages of 19 and 29 attending the University in Chungnam. An ultrasound was used to measure diaphragm movement, while a tape measure was used to measure thoracic mobility before and after wearing a baby carrier. In addition, the FVC was measured using a spirometer. Diaphragm movement, thoracic mobility, and FVC were significantly decreased after wearing the baby carrier. These results suggest that wearing a baby carrier can negatively affect thoracic mobility, diaphragm movement, and FVC in healthy adult males.

A Podaegi is a square cloth used to carry a baby. Podaegi was an essential necessity for raising baby. However currently Koreans prefer baby-carriers, baby hip-seats, and equipments other than Podaegi. Recently, Podaegi is becoming popular around the world. Therefore, it is necessary to study Podaegi to inform Korea's traditional parenting culture product. In this research, 230 images of Podaegi were collected from paintings, photographs, postcards, films and artifacts from the late 18th century to 2000. The period of study was divided into three phases from the late Joseon Dynasty to before the opening of the port, from the opening of the port to before the liberation, and from the liberation to 2000. Types of Podaegi were categorized according to its shape and how to use. Transition process of Podaegi was examined. Podaegis were categorized into band type, blanket type, combination type, cheone type, modern type, and so on. From the late Joseon Dynasty to before the pre-openings, band type was used. From the opening of the port to liberation, all types of Podaegi appeared. Since the liberation, the use of band and blanket type has gradually decreased. Modern types have been the most popular since the 1960s. Materials of Podaegi became varied and Podaegi became a fashion-item. Later, modern Podaegi became the representative form of Korean traditional Podaegi.

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.
