Upper-limb loss in young children poses stark challenges for healthy development, and participation in society. Earlier prosthesis use is associated with lower rejection rates and better outcomes, particularly with active rather than cosmetic devices. Yet NHS provision of such prostheses is limited. Practical challenges include children's rapid growth-rate, and extensive fitting/production times for conventional prostheses. Ambionics develops and produces upper-limb prostheses for young children, tackling these challenges using rapid-prototyping technology to produce individualized prostheses quickly. We now address the challenge of developing prostheses that are maximally functional and intuitive to use. This is valuable practically because young children lack the cognitive/communication skills for conventional training. More fundamentally, natural hand movements are fluid and efficient because they involve automatic, anticipatory sensorimotor processes. Prostheses would ideally be controlled similarly, yet little is known about conditions required for this to occur, particularly in children. We will use theories/methods from movement science to determine fundamental principles governing intuitive prosthesis use in children. Departures from automatic, anticipatory control will reveal directions for improving design and function, and thus long-term outcomes.

幼儿上肢丧失给健康发展和社会参与带来严峻挑战。较早使用假体可以降低排斥率并获得更好的效果，尤其是使用主动假体而不是美容假体。然而，NHS 提供的此类假肢是有限的。实际挑战包括儿童的快速生长速度以及传统假肢的安装/生产时间长。 Ambionics 为幼儿开发和生产上肢假肢，利用快速原型技术快速生产个性化假肢来应对这些挑战。我们现在面临的挑战是开发功能最大化且使用直观的假肢。这实际上很有价值，因为幼儿缺乏常规训练的认知/沟通技能。更根本的是，自然的手部动作是流畅且高效的，因为它们涉及自动的、预期的感觉运动过程。理想情况下，假肢也应该受到类似的控制，但人们对发生这种情况所需的条件知之甚少，尤其是在儿童中。我们将使用运动科学的理论/方法来确定儿童直观假肢使用的基本原则。偏离自动预期控制将揭示改进设计和功能的方向，从而揭示长期结果。
