Tablet technology is a promising tool for assisting therapeutic strategies in stroke rehabilitation. However, it is not clear whether the basic gestures (e.g. click, double-click) are feasible.
This study aimed to assess the successful performance of gestures and associated factors.
This cross-sectional study was conducted at a rehabilitation center in Austria. The successful tablet use was checked on a Samsung Galaxy Tab 4 (10.1 Wi-Fi 25.6 cm; 10.1 Zoll) with a specifically developed app. To identify factors associated with successful use, impairments in activities of daily living (Barthel index), cognitive functions (Montreal Cognitive Assessment, MoCA), motor functions (Nine-Hole Peg Test), and grip strength (handgrip dynamometer) were assessed.
One hundred and twenty-nine participants were analyzed, whereof 53.5% had a paretic upper limp and 69.2% were able to perform all gestures with at least one hand. Factors associated with successful use were higher Barthel index (OR: 1.06; 95% CI = 1.01-1.11) and MoCA (OR: 1.21; 95% CI = 1.01-1.44), whereas lower age (OR: 0.91; 95% CI = 0.83-0.99) and a paretic hand (OR: 0.12; 95% CI = 0.01-0.99) were associated with a lesser likelihood. Additionally, 18.6% successfully performed all gestures with the paretic hand, whereof 74% could not perform the double-click and 77.0% were not able to zoom.
The majority of stroke patients are able to perform the basic gestures on a tablet with at least one hand, but only few patients with paresis could do them. Gestures like double-clicking and zooming should be avoided when designing apps for rehabilitation, as especially these were found difficult.
平板电脑技术是辅助中风康复治疗策略的一种有前景的工具。然而，基本手势（如点击、双击）是否可行尚不清楚。
本研究旨在评估手势的成功执行情况及相关因素。
这项横断面研究在奥地利的一家康复中心进行。使用一款专门开发的应用程序，在三星Galaxy Tab 4（10.1 Wi-Fi 25.6厘米；10.1英寸）上检查平板电脑的成功使用情况。为了确定与成功使用相关的因素，评估了日常生活活动能力（巴氏指数）、认知功能（蒙特利尔认知评估量表，MoCA）、运动功能（九孔插板试验）和握力（握力计）方面的损伤。
对129名参与者进行了分析，其中53.5%的人上肢有偏瘫，69.2%的人能够用至少一只手执行所有手势。与成功使用相关的因素是较高的巴氏指数（OR：1.06；95%CI = 1.01 - 1.11）和MoCA（OR：1.21；95%CI = 1.01 - 1.44），而年龄较小（OR：0.91；95%CI = 0.83 - 0.99）和患侧手（OR：0.12；95%CI = 0.01 - 0.99）与成功可能性较小相关。此外，18.6%的人能用患侧手成功执行所有手势，其中74%不能执行双击，77.0%不能进行缩放操作。
大多数中风患者能够用至少一只手在平板电脑上执行基本手势，但只有少数偏瘫患者可以做到。在设计康复应用程序时应避免使用双击和缩放等手势，因为这些手势尤其难以执行。
