The objective of this study is to highlight the effect of a robotic driver assistance module of powered wheelchair (PWC), using infrared sensors and accessorizing a commercial wheelchair) on the reduction of the number of collisions in standardized circuit in a population with neurological disorders by comparing driving performance with and without assistance. This is a prospective, single-center, controlled, repeated measure design, single-blind pilot study including patients with neurological disabilities who are usual drivers of electric wheelchairs. The main criterion for evaluating the device is the number of collisions with and without the assistance of a prototype anti-collision system on three circuits of increasing complexity. Travel times, cognitive load, driving performance, and user satisfaction are also analyzed. 23 Patients, 11 women and 12 men with a mean age of 48 years old completed the study. There was a statistically significant reduction in the number of collisions on the most complex circuit: 61% experienced collisions without assistance versus 39% with assistance (p = 0.038). This study concludes that the PWC driving assistance module is efficient in terms of safety without reducing the speed of movement in a population of people with disabilities who are habitual wheelchair drivers. The prospects are therefore to conduct tests on a target population with driving failure or difficulty who could benefit from this device so as to allow them to travel independently and safely.

SWADAPT1：标准化电路中电动轮椅驱动机器人模块的评估：一项前瞻性、受控重复测量设计试点研究

本研究的目的是强调电动轮椅 (PWC) 的机器人驾驶员辅助模块（使用红外传感器并配备商用轮椅）对减少神经系统疾病人群标准化电路碰撞次数的影响。比较有辅助和无辅助的驾驶性能。这是一项前瞻性、单中心、受控、重复测量设计、单盲试验研究，包括通常驾驶电动轮椅的神经障碍患者。评估该设备的主要标准是在复杂性不断增加的三个电路上，有无原型防碰撞系统辅助的碰撞次数。还分析了旅行时间、认知负荷、驾驶性能和用户满意度。23 名患者，平均年龄为 48 岁的 11 名女性和 12 名男性完成了这项研究。在最复杂的赛道上，碰撞次数在统计学上显着减少：61% 的人在没有帮助的情况下发生碰撞，39% 的人在有帮助的情况下发生碰撞（p = 0.038）。本研究得出的结论是，PWC 驾驶辅助模块在安全方面是有效的，而不会降低惯用轮椅司机的残疾人群体的移动速度。因此，前景是对可以从该设备中受益的驾驶失败或困难的目标人群进行测试，以使他们能够独立安全地旅行。61% 的人在没有帮助的情况下经历了碰撞，而 39% 的人在没有帮助的情况下经历了碰撞（p = 0.038）。本研究得出的结论是，PWC 驾驶辅助模块在安全方面是有效的，而不会降低惯用轮椅司机的残疾人群体的移动速度。因此，前景是对可以从该设备中受益的驾驶失败或困难的目标人群进行测试，以使他们能够独立安全地旅行。61% 的人在没有帮助的情况下经历了碰撞，而 39% 的人在没有帮助的情况下经历了碰撞（p = 0.038）。本研究得出的结论是，PWC 驾驶辅助模块在安全方面是有效的，而不会降低惯用轮椅司机的残疾人群体的移动速度。因此，前景是对可以从该设备中受益的驾驶失败或困难的目标人群进行测试，以使他们能够独立安全地旅行。
