The aim of the present study was to describe and test the reliability of a comprehensive product-centered approach to assessing functional performance and wheelchair user perceptions on device ergonomics and satisfaction of performance. A pilot study was implemented using this approach to evaluate differences among four manual wheelchairs.
Six wheelchair users with complete spinal cord injury (SCI) at the thoracic level and with no previous upper limbs impairment were recruited for this study. After finishing circuit tasks, subjects were asked to complete a questionnaire about ergonomic wheelchair characteristics (manoeuvrability, stability, comfort and ease of propulsion) and satisfaction about task performance. On the other hand, objective data were recorded during user performance as the time required to complete each test, kinetic wheelchair propulsion data obtained with two SMARTWheels® and physiological parameters (heart rate and physiological index).
Kuschall Champion® and Otto Bock Voyage® wheelchairs were ranked best for most ergonomic aspects specially in manoeuvrability (p < 0.05). Less time was required to execute most of the circuit tasks in both wheelchair models (p < 0.05).
This approach proposed highlight the importance of looking both kinds of information, user perception and user functional performance when evaluating a wheelchair or comparing across devices.
本研究旨在描述并测试一种以产品为中心的综合方法的可靠性，该方法用于评估功能性能以及轮椅使用者对设备人体工程学和性能满意度的看法。采用这种方法进行了一项试点研究，以评估四种手动轮椅之间的差异。
招募了六名胸段完全性脊髓损伤（SCI）且既往无上肢损伤的轮椅使用者参与本研究。完成巡回任务后，要求受试者完成一份关于轮椅人体工程学特征（可操作性、稳定性、舒适性和推进 ease）以及对任务表现满意度的问卷。另一方面，在使用者执行任务期间记录客观数据，包括完成每项测试所需的时间、使用两个SMARTWheels®获得的轮椅推进动力学数据以及生理参数（心率和生理指标）。
Kuschall Champion®和奥托博克Voyage®轮椅在大多数人体工程学方面排名最佳，特别是在可操作性方面（p < 0.05）。两种轮椅型号执行大多数巡回任务所需的时间较少（p < 0.05）。
所提出的这种方法强调了在评估轮椅或跨设备比较时，同时考虑用户感知和用户功能性能这两种信息的重要性。
