The leap motion controller (LMC) is a new optoelectronic system for capturing motion of both hands and controlling a virtual environment. Differently from previous devices, it optoelectronically tracks the fine movements of fingers neither using glows nor markers.
This pilot study explored the feasibility of adapting the LMC, developed for videogames, to neurorehabilitation of elderly with subacute stroke.
Four elderly patients (71.50 ± 4.51 years old) affected by stroke in subacute phase were enrolled and tested in a cross-over pilot trial in which six sessions of 30 minutes of LMC videogame-based therapy were added on conventional therapy. Measurements involved participation to the sessions, evaluated by means of the Pittsburgh Rehabilitation Participation Scale, hand ability and grasp force evaluated respectively by means of the Abilhand Scale and by means of the dynamometer.
Neither adverse effects nor spasticity increments were observed during LMC training. Participation to the sessions was excellent in three patients and very good in one patient during the LMC trial. In this period, patients showed a significantly higher improvement in hand abilities (P = 0.028) and grasp force (P = 0.006).
This feasibility pilot study was the first one using leap motion controller for conducting a videogame-based therapy. This study provided a proof of concept that LMC can be a suitable tool even for elderly patients with subacute stroke. LMC training was in fact performed with a high level of active participation, without adverse effects, and contributed to increase the recovery of hand abilities.
Leap Motion控制器（LMC）是一种新型光电系统，用于捕捉双手运动并控制虚拟环境。与以前的设备不同，它通过光电方式跟踪手指的精细运动，既不使用发光装置也不使用标记物。
本初步研究探讨了将为电子游戏开发的LMC应用于亚急性中风老年患者神经康复的可行性。
招募了4名亚急性期中风的老年患者（71.50±4.51岁），并在一项交叉试验中进行测试，在常规治疗的基础上增加了6节30分钟基于LMC电子游戏的治疗课程。测量内容包括通过匹兹堡康复参与量表评估的参与课程情况，通过Abilhand量表和测力计分别评估的手部能力和握力。
在LMC训练期间未观察到不良反应或痉挛增加。在LMC试验期间，3名患者参与课程的情况为优秀，1名患者为良好。在此期间，患者的手部能力（P = 0.028）和握力（P = 0.006）有显著提高。
这项可行性初步研究是首次使用Leap Motion控制器进行基于电子游戏的治疗。该研究提供了一个概念验证，即LMC即使对于亚急性中风的老年患者也可能是一种合适的工具。事实上，LMC训练是在高度积极参与的情况下进行的，没有不良反应，并有助于提高手部能力的恢复。
