摘要
对于残疾学步儿童来说,使用电动移位机有助于他们的游戏和发展。有理论认为,以站立姿势使用电动移位机有助于肌肉协调、平衡、头部和躯干稳定性以及向步行过渡的发展。本研究的目的是量化和描述在坐姿和支撑站立姿态下使用 Permobil Mini 探险家手柄时的操纵杆控制、体重支撑和肌肉活动。九名行动不便的儿童参加了四次探访,他们完成了两次 15-20 分钟的游戏,每种姿势各一次,中间休息一次。我们发现,所有学步儿童在两种姿势下都能使用操纵杆,但在偏好方向和控制模式上存在个体差异。两种姿势下,参与者通过脚部的负荷量相似,但站立时的肌肉活动略高,尤其是在驾驶时。这些结果表明,残疾幼儿在坐姿和站姿下都能很快使用操纵杆电动移动,其中存在重要的个体差异,可为未来设计支持游戏和发展的设备和干预措施提供参考。
Quantifying toddler exploration in different postures with powered mobility.
Access to powered mobility can support play and development for toddlers with disabilities. Using powered mobility in a standing posture has been theorized to support development of muscle coordination, balance, head and trunk stability, and transition to ambulation. The purpose of this study was to quantify and characterize joystick control, bodyweight support, and muscle activity while using the Permobil Explorer Mini in seated and supported standing postures. Nine children with mobility disabilities participated in four visits where they completed two, 15-20 minute play sessions, one in each posture, with a break between. We found that all toddlers engaged with the joystick in both postures, with individual differences in favored directions and control patterns. Participants had similar loading through their feet in both postures, but had slightly higher muscle activity in standing, especially while driving. These results demonstrate that young children with disabilities quickly engage with joystick-based powered mobility in seated and standing postures, with important individual differences that can inform future design of devices and interventions to support play and development.
期刊介绍:
Assistive Technology is an applied, scientific publication in the multi-disciplinary field of technology for people with disabilities. The journal"s purpose is to foster communication among individuals working in all aspects of the assistive technology arena including researchers, developers, clinicians, educators and consumers. The journal will consider papers from all assistive technology applications. Only original papers will be accepted. Technical notes describing preliminary techniques, procedures, or findings of original scientific research may also be submitted. Letters to the Editor are welcome. Books for review may be sent to authors or publisher.
