EEG datasets of stroke patients

This data set consists of electroencephalography (EEG) data from 50 (Subject1 – Subject50) participants with acute ischemic stroke aged between 30 and 77 years. The participants included 39 male and 11 female. The time after stroke ranged from 1 days to 30 days. 22 participants had right hemisphere hemiplegia and 28 participants had left hemisphere hemiplegia. All participants were originally right-handed. Each of the participants sat in front of a computer screen with an arm resting on a pillow on their lap or on a table and they carried out the instructions given on the computer screen. At the trial start, a picture with text description which was circulated with left right hand, were presented for 2s. We asked the participants to focus their mind on the hand motor imagery which was instructed, at the same time, the video of ipsilateral hand movement is displayed on the computer screen and lasts for 4s. Next, take a 2s break.

本数据集包含50名受试者（编号为Subject1至Subject50）的脑电图（electroencephalography，EEG）数据，所有受试者均为年龄介于30至77岁的急性缺血性脑卒中患者，其中男性39名、女性11名。受试者发病至数据采集的卒中后时长为1天至30天；22名患者表现为右侧半球偏瘫，28名患者表现为左侧半球偏瘫，且所有受试者均为右利手。每名受试者坐在电脑屏幕前，将手臂放置于大腿或桌面的枕头上，按照电脑屏幕上的指示完成实验任务。试验开始时，一幅带有文字说明的提示画面将呈现2秒，该画面指示受试者进行左手或右手的运动想象；实验过程中，要求受试者专注于被指定的手部运动想象，与此同时电脑屏幕将播放同侧手部运动的视频，时长为4秒，随后进入时长2秒的休息阶段。
