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名年龄介于30至77岁的急性缺血性脑卒中参与者（编号为Subject1至Subject50）的脑电图（electroencephalography, EEG）数据。该队列中男性39名，女性11名；受试者脑卒中发病后时间跨度为1天至30天。其中22名存在右侧半球偏瘫，28名存在左侧半球偏瘫，所有参与者原本均为右利手。每位受试者坐在电脑屏幕前，将手臂放置于膝部垫枕或桌面之上，按照电脑屏幕上的指示完成实验任务。试验启动时，一张带有文字说明、用于提示左右手运动想象的图片将呈现2秒。实验要求受试者专注于被指示的手部运动想象，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。随后将进入2秒的休息时段。
