ABSTRACT

The setting in which wheelchair transfers are performed can affect the difficulty and the risks associated with completion. This article presents results from an observational study involving 13 wheelchair users performing independent transfers across four settings. The aim is to understand how the environment affects how different types of independent transfers are performed. Descriptive analysis was performed alongside an objective assessment using the Transfer Assessment Instrument (TAI). The perceived difficulty reported after each transfer was also collected. Two participants exhibited radically different transferring techniques in different scenarios. Additionally, the transferring scenario was found to significantly affect the perceived difficulty of sitting transfers (toilet 2.17 ±.88; bed 1.47 ±.65, p =.001; car 1.63 ±.82, p =.012) and standing transfers (car 3.5 ±.71; bed 1 ± 0, p =.03; toilet 1 ± 0, p =.03), and the TAI score attributed to sitting pivot with use of a transfer board (couch 4.3 ±.88; bed 6.93 ± 1.29, p =.022; car 7.13 ± 1.32, p =.018). Overall, environmental constraints can lead to major technique changes and, more often, to different positioning of hands and feet which could impact the transfer’s biomechanics.

摘要

进行轮椅转移的环境会影响完成相关的难度和风险。本文介绍了一项观察性研究的结果，该研究涉及 13 名轮椅使用者在四种环境中进行独立转移。目的是了解环境如何影响不同类型的独立传输的执行方式。描述性分析与使用转移评估工具 (TAI) 的客观评估一起进行。还收集了每次转移后报告的感知困难。两名参与者在不同的场景中展示了截然不同的传输技术。此外，发现转移场景显着影响坐着转移的感知难度（厕所 2.17 ±.88；床 1.47 ±.65，p=.001; 汽车 1.63 ±.82，p =.012）和站立转移（汽车 3.5 ±.71；床 1 ± 0，p =.03；厕所 1 ± 0，p =.03），以及归因于坐姿枢轴的 TAI 分数使用转移板（沙发 4.3 ±.88；床 6.93 ± 1.29，p =.022；汽车 7.13 ± 1.32，p =.018）。总体而言，环境限制可能导致重大的技术变化，并且更常见的是导致手和脚的不同定位，这可能会影响转移的生物力学。
