Walking with luggage is a common daily activity. While its effects on gait and posture have been explored, most findings are based on laboratory measurements rather than real-world conditions. This cross-sectional study aimed to investigate the effects of walking with luggage on gait and posture in everyday environments using an in-shoe motion sensor system. Gait parameters of 26 healthy, pain-free young adults were assessed over a 10-minute period under four conditions: no luggage, using a backpack, a shoulder bag, and a crossbody bag. Gait data were recorded at 2-minute intervals using an in-shoe motion sensor system. The averages of the valid right and left gait measurements were automatically calculated. Data were analyzed by comparing mean values and symmetry indices. There were differences in stance time, pushing time, cadence, and walking speed between mean values of each luggage. Asymmetry was most notable in pushing time and maximum swing-phase speed. Spatial parameters showed minimal variations. We concluded that the type of luggage carried can alter gait. Recognizing these differences may help prevent conditions, such as knee osteoarthritis, provide daily life guidance, and enhance overall well-being. Future research could expand these findings by considering various luggage weights and a broader age demographic.
携带行李行走是一项常见的日常活动。虽然已经探讨了其对步态和姿势的影响，但大多数研究结果是基于实验室测量而非实际生活条件。这项横断面研究旨在使用鞋内运动传感器系统，调查在日常环境中携带行李行走对步态和姿势的影响。在四种条件下，对26名健康、无疼痛的年轻成年人在10分钟内的步态参数进行了评估：不携带行李、使用背包、单肩包和斜挎包。使用鞋内运动传感器系统每隔2分钟记录一次步态数据。自动计算有效右、左步态测量值的平均值。通过比较平均值和对称指数对数据进行分析。每种行李的平均值在站立时间、蹬地时间、步频和步行速度方面存在差异。不对称在蹬地时间和最大摆动相速度方面最为明显。空间参数变化最小。我们得出结论，携带的行李类型会改变步态。认识到这些差异可能有助于预防诸如膝关节骨关节炎等疾病，提供日常生活指导，并提高整体幸福感。未来的研究可以通过考虑各种行李重量和更广泛的年龄人群来扩展这些发现。
