abstract="【Objective】The purpose of this study was to identify the factors that increase the risk of falling when carrying a handbag. Postural responses were compared with and without a handbag when the subjects were given a simulated slip stimulus during walking on a split-belt treadmill.【Subjects and Methods】The subjects of this study were 20 healthy adult males. The simulated slip stimulation was given to the right foot at heel contact. The three measurement conditions were left handbag, right handbag, and empty-handed walking. A three-dimensional motion analysis system was used to record the positional and temporal information of body landmarks, and the body axis and virtual center of mass were calculated from the position data.【Results】The postural response to the simulated slip stimulation was classified into two categories: &quot;single leg support response (S-response)&quot; and &quot;double leg support response (DS-response)&quot;. In the S-response, the subjects stepped on the opposite foot of the stimulated lower limb. In the DS-response, the subjects stood on both legs without a step. The subjects tilted the trunk more to the posterior, and the virtual center of mass showed larger backward displacement in the S-response than in the DS-response. The subjects tilted the trunk more to the right, and the virtual center of mass showed larger rightward displacement in the DS-response than in the S-response. A larger number of DS-responses occurred when the handbag was held with the right hand. The start timing of stepping in the S-responses was delayed when the handbag was held with the right hand.【Conclusion】Slips of the foot on the handbag side at heel contact during walking are more dangerous than slips that happen on the other side, and the start timing of stepping was delayed. However, it is not possible to predict which foot will slip. Therefore, holding a handbag may increase the fall risk during walking compared to walking empty-handed.  <p>Language: ja</p>",
