■虚拟现实/严肃游戏(SG)和功能性电刺激(FES)疗法用于上肢中风康复。两种方法的组合似乎对治疗成功有益。研究了SG和对侧EMG触发的FES(SGFES)组合的可行性以及此类疗法的响应者的特征。
■在一项随机交叉试验中,患者进行两种游戏条件:SG单独和SG+FES。使用内在动机清单(IMI)评估治疗系统的可行性,Nasa任务负载索引,和系统可用性量表(SUS)。游戏参数,疲劳程度和技术文件已实施,以获取更多信息。
■总共,本研究分析了18例中风后(62.1±14.1年)上肢单侧轻瘫(MRC≤4)的患者。这两个条件都被认为是可行的。比较条件之间的IMI分数,在SG+FES期间,训练期间感知能力显著增加(z=-2.88,p=0.004),压力/紧张(z=-2.13,p=0.034)降低.此外,在SG+FES条件下,任务负载的额定值显着降低(z=-3.14,p=0.002),特别是实物需求(z=-3.08,p=0.002),性能较好(z=-2.59,p=0.010)。对SUS的反应和感知的疲劳水平在条件之间没有差异(SUS:z=-0.79,p=0.431;疲劳:z=1.57,p=0.115)。对于轻度至中度损伤(MRC3-4)的患者,联合治疗没有或几乎没有游戏益处。额外使用对侧控制的FES(ccFES),然而,使严重受损患者(MRC0-1)能够玩SG。
■SG与ccFES的组合在卒中后患者中是可行的且被广泛接受的。似乎额外使用ccFES可能对严重受损的患者更有益,因为它可以执行严肃的游戏。这些发现为康复系统的发展提供了有价值的意义,通过结合不同的治疗干预措施来增加患者的利益,并提出了家庭使用的系统修改。

UNASSIGNED: Virtual Reality/serious games (SG) and functional electrical stimulation (FES) therapies are used in upper limb stroke rehabilitation. A combination of both approaches seems to be beneficial for therapy success. The feasibility of a combination of SG and contralaterally EMG-triggered FES (SG+FES) was investigated as well as the characteristics of responders to such a therapy.
UNASSIGNED: In a randomized crossover trial, patients performed two gaming conditions: SG alone and SG+FES. Feasibility of the therapy system was assessed using the Intrinsic Motivation Inventory (IMI), the Nasa Task Load Index, and the System Usability Scale (SUS). Gaming parameters, fatigue level and a technical documentation was implemented for further information.
UNASSIGNED: In total, 18 patients after stroke (62.1 ± 14.1 years) with a unilateral paresis of the upper limb (MRC ≤4) were analyzed in this study. Both conditions were perceived as feasible. Comparing the IMI scores between conditions, perceived competence was significantly increased (z = -2.88, p = 0.004) and pressure/tension during training (z = -2.13, p = 0.034) was decreased during SG+FES. Furthermore, the task load was rated significantly lower for the SG+FES condition (z = -3.14, p = 0.002), especially the physical demand (z = -3.08, p = 0.002), while the performance was rated better (z = -2.59, p = 0.010). Responses to the SUS and the perceived level of fatigue did not differ between conditions (SUS: z = -0.79, p = 0.431; fatigue: z = 1.57, p = 0.115). For patients with mild to moderate impairments (MRC 3-4) the combined therapy provided no or little gaming benefit. The additional use of contralaterally controlled FES (ccFES), however, enabled severely impaired patients (MRC 0-1) to play the SG.
UNASSIGNED: The combination of SG with ccFES is feasible and well-accepted among patients after stroke. It seems that the additional use of ccFES may be more beneficial for severely impaired patients as it enables the execution of the serious game. These findings provide valuable implications for the development of rehabilitation systems by combining different therapeutic interventions to increase patients\' benefit and proposes system modifications for home use.
