To determine if older adult, novice wheelchair users who drive a power wheelchair with a JoyBar control complete maneuverability tasks in less time and with less error than those who drive a power wheelchair with a standard joystick control.
A parallel randomized controlled trial design conducted at a medical rehabilitation and research centre with ambulatory older adults aged 60 and above (n = 27). The intervention was the JoyBar alternative wheelchair control. The primary outcome measure was total time to complete each of the two maneuverability tasks. The secondary outcome measure was total number of errors during each of the maneuverability tasks.
An independent, two sampled t-test was conducted and revealed that the JoyBar group took a greater amount of time to complete both maneuverability tasks than the control group (p < .05). No significant differences (p < .05) were found in rates of error on either task between the JoyBar and joystick groups.
Maneuverability of a powered wheelchair by novice wheelchair users was not improved through the use of the JoyBar when compared to a standard wheelchair joystick, as measured by rates of error and time to complete maneuverability tasks. Implications for rehabilitation Clients who are new to powered wheelchair use may perform maneuverability tasks faster, with equivalent accuracy, using a standard joystick versus the JoyBar. Clients who use a JoyBar may require adjustments to the programming of their wheelchair to ensure optimal performance. Additional training may be required to achieve proficiency in maneuverability tasks with a JoyBar versus a standard joystick.
确定与使用标准操纵杆控制的电动轮椅的老年人相比，使用JoyBar控制的电动轮椅的老年新手轮椅使用者完成机动性任务的时间是否更短，错误是否更少。
在一家医学康复与研究中心对60岁及以上的能行走的老年人（n = 27）进行了一项平行随机对照试验设计。干预措施是JoyBar替代轮椅控制。主要结局指标是完成两项机动性任务各自所需的总时间。次要结局指标是每项机动性任务期间的错误总数。
进行了独立的双样本t检验，结果显示JoyBar组完成两项机动性任务的时间均比对照组更长（p < .05）。JoyBar组和操纵杆组在任何一项任务上的错误率均未发现显著差异（p < .05）。
与标准轮椅操纵杆相比，新手轮椅使用者使用JoyBar时电动轮椅的机动性并未提高，这通过错误率和完成机动性任务的时间来衡量。对康复的启示 刚开始使用电动轮椅的患者使用标准操纵杆可能比使用JoyBar更快地完成机动性任务，且准确性相当。使用JoyBar的患者可能需要调整其轮椅的编程以确保最佳性能。与标准操纵杆相比，使用JoyBar可能需要额外的训练才能熟练完成机动性任务。
