Abstract

OBJECTIVE

The aim of this study was to determine whether manoeuvrability varied between electric wheelchairs.

DESIGN

Randomized, prospective, repeated measures design.

SUBJECTS

Twelve wheelchair users.

METHODS

Three different electric powered indoor/outdoor wheelchairs (Invacare Storm 3, Ottobock B500, and Meyra Champ) intended for use by patients with severe impairments were tested over an indoor and an outdoor circuit. Points were assigned when the users touched the circuit boundaries or failed to pass obstacles. The users completed the Quebec User Evaluation of Satisfaction with Assistive Technology questionnaire (QUEST).

RESULTS

Performance was significantly worse with Ottobock B500 compared with the other 2 wheelchairs on the indoor test (Wilcoxon, p < 0.05 for both comparisons) and compared with Invacare Storm on the outdoor test (Wilcoxon, p < 0.05). The mean 6-item QUEST score, effectiveness, and simplicity of use were significantly worse for Ottobock B500 than for the other 2 wheelchairs (Wilcoxon, p < 0.05).

CONCLUSION

Differences in manoeuvrability exist between commercially available electric wheelchairs belonging to the same category. Driving tests and QUEST provide complementary and concordant information.

摘要

目的

本研究旨在确定电动轮椅的机动性是否存在差异。

设计

随机、前瞻性、重复测量设计。

受试者

12 名轮椅使用者。

方法

对 3 种不同的室内/室外电动轮椅（Invacare Storm 3、Ottobock B500 和 Meyra Champ）进行测试，这些轮椅供严重受损的患者使用。当使用者触及电路边界或未能通过障碍物时，将给予相应的分数。使用者完成了魁北克用户对辅助技术满意度评估问卷（QUEST）。

结果

在室内测试中，Ottobock B500 的性能明显比其他 2 款轮椅差（Wilcoxon，p < 0.05，两种比较均如此），在室外测试中，与 Invacare Storm 相比，Ottobock B500 的性能也更差（Wilcoxon，p < 0.05）。Ottobock B500 的 QUEST 量表的 6 项平均得分、有效性和使用简便性明显差于其他 2 款轮椅（Wilcoxon，p < 0.05）。
