Research investigating walkers suggests that safety and assistance for the elderly with weak lower limbs were important. However, the relationship between the use of a walker and the upper limbs has received little investigation. Standing up and sitting down are important daily activities. Therefore, the aim of this study was to explore wrist deviation and vertical force among elderly individuals using a walker for assistance to stand up and sit down. In total, 64 elderly volunteers (M age = 80.22, SD = 9.36) were enrolled. Data were obtained from four load cells and a twin-axis wrist goniometer. Wrist deviation and vertical force were examined when participants used a walker with horizontal handles to assist in standing up and sitting down. Significant wrist angle deviation occurred with the use of a walker, with dorsiflexion of the right hand greater than that of the left. Males exerted significantly greater vertical force. In the sitting position, greater ulnar deviation was seen among experienced walker users, whereas during standing, experienced users exhibited greater dorsiflexion. The horizontal handles of most marketed walkers may cause user wrist deviations, suggesting researchers should pursue improvements in walker design.
研究表明，助步器对下肢虚弱的老年人的安全和辅助非常重要。然而，助步器与上肢的关系却很少受到关注。站立和坐下是重要的日常活动。因此，本研究旨在探讨使用助步器辅助站立和坐下时老年人的手腕偏斜和垂直力。共有 64 名老年志愿者（M 年龄=80.22，SD=9.36）参与了研究。数据来自四个负载单元和一个双轴手腕量角器。当参与者使用带有水平把手的助步器辅助站立和坐下时，检测了手腕偏斜和垂直力。使用助步器时手腕角度明显偏斜，右手背屈大于左手。男性施加的垂直力明显更大。在坐姿中，有经验的助步器使用者出现更大的尺侧偏斜，而在站立时，有经验的使用者表现出更大的背屈。市场上大多数助步器的水平把手可能会导致使用者手腕偏斜，这表明研究人员应该寻求改进助步器设计。
