Effect of slipper wearing and carrying positions of infant on dynamic stability and kinetic variable during level walking

Abstract

Recently though various hip seats for carrying infant of women was de-signed and developed, then, wearing slipper may restrain the move-ment of bare foot. The study was undertaken to investigate the dynamic stability and kinetic variables according to between position of carrying infant and wearing slipper. Adult female (n=10) and under one year age of infant (n=10) participated in the study. Extrapolated center of mass, center of pressure, ground reaction force (GRF), and leg stiffness of gait characteristics using 3-dimensional cinematography and GRF were an-alyzed. Dynamic stability according to position of carrying infant and wearing slipper was not significant. While when carried an infant against normal gait showed significant difference in breaking force, leg stiffness and loading rate (P < 0.001). Of which breaking force and verti-cal impulse were more increased when the back-carried against fore-carried of trunk. Thus it resulted in transformation on types of im-pulse transfer to leg and COG of women's carrying infant, which may be strategy for securing a dynamic stability. Therefore experts related with exercise rehabilitation should understand sufficiently on gait character-istics of women with diseases on muscular-skeletal system and per-form effective rehabilitation and treatment.
