Abstract

INTRODUCTION

The gait while using an intravenous (IV) pole is close to the gait of the elderly and fallers. Additionally, one survey has reported that the diagonal position is optimal for transporting an IV pole with a light load. However, in clinical practice, carrying a heavier load may be possible. Therefore, this study clarifies the optimum operation position using an IV pole with a weight closer to that in actual clinical practice.

METHOD

Using image analysis software, we investigated several variables indicating gait, such as stride length. Participants walk with an IV pole in three ways: sideways, in front, and diagonally. We investigated two types of IV pole loads, which are 0.5 kg and 5.0 kg.

RESULTS AND DISCUSSION

In 0.5-kg settings, the sideways position is a way to suppress the narrowing of the heel-floor angle. No significant difference in the subjective appraisals was observed between the sideways and diagonal positions. In addition, the sideways position is as optimum as the diagonal position. In 5.0-kg settings, only the sideways position suppressed the narrowing of the step length. Therefore, the sideways position is optimal. However, the participants' impressions suggested that arm strength is required for the sideways position. If a patient has weak arms and cannot maintain the sideways position, the patient may choose the diagonal position. Moreover, the front position is the way to hold the trunk most forward. However, there is a possibility that it is easy for a specific person, such as a rollator user, to choose. Therefore, further investigate of the optimum operation position depending on the walking abilities is needed.

CONCLUSION

It was suggested that the sideways position is optimal for walking with an IV pole when transporting with a total load of approximately 5.0 kg.Clinical Relevance- The results of this study help to prevent people from gait like fallers and the elderly when using IV poles in clinical settings.

摘要

简介

使用静脉输液（IV）杆的步态与老年人和跌倒者的步态相近。此外，有一项调查表明，对角位置对于轻负载下运输 IV 杆是最佳的。然而，在临床实践中，可能需要携带更重的负载。因此，本研究使用更接近实际临床实践中重量的 IV 杆来确定最佳操作位置。

方法

我们使用图像分析软件研究了几个表示步态的变量，如步长。参与者以三种方式用 IV 杆行走：侧身、前方和对角。我们研究了两种 IV 杆负载类型，分别为 0.5 公斤和 5.0 公斤。

结果与讨论

在 0.5 公斤的设置中，侧身位置是抑制脚跟-地面角度变窄的一种方法。在侧身和对角位置之间，没有观察到主观评估的显著差异。此外，侧身位置与对角位置一样最佳。在 5.0 公斤的设置中，只有侧身位置抑制了步长的变窄。因此，侧身位置是最佳的。然而，参与者的印象表明，侧身位置需要手臂力量。如果患者手臂无力，无法保持侧身位置，患者可能会选择对角位置。此外，前方位置是将躯干保持最靠前的方式。然而，对于特定的人，如助行器使用者，选择这种位置的可能性较大。因此，需要进一步根据行走能力研究最佳操作位置。
