The aim of this study was to analyze the relation between incline angle of whole body and kinematic variables at tripping during gait. The par-ticipants consisted of healthy adult female (n=6). The three- dimension-al (3D) motion analysis of posture restoring after inducing tripping of right foot at supporting phase of left foot was performed. As a result, supporting time elapsed of one stride and one foot at tripping showed longer than that of normal gait. The length of one stride showed longer at tripping than that of normal gait, and velocity of center of gravity (COG) showed faster at tripping than that of normal gait. Anteriorposte-rior incline angle of whole body showed more forwarded incline at trip-ping than that of normal gait. As a result of correlation among variables, one stride and supporting time elapsed showed positive relation r=0.973 (R2=0.947, P<0.001), also r=0.920 (R2=0.846, P<0.001) relative to velocity of COG, r=0.970 (R2=0.941, P<0.001) of 1-stride time elapsed relative to velocity of COG and r=0.833 (R2=0.613, P<0.05) of velocity of COG relative to anteriorposterior incline angle respectively. Therefore instantaneous stoppage of gait posture when tripped at supporting phase of one leg during gait may be impossible and rather may cause a recovery of gait pattern when secured the faster velocity of COG and the longer of supporting time elapsed of one leg.
