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名急性缺血性脑卒中（acute ischemic stroke）患者的脑电图（electroencephalography, EEG）数据，受试者编号为Subject1至Subject50，年龄介于30至77岁之间。其中男性39名，女性11名；卒中后时长为1至30天。22名受试者存在右侧半球偏瘫，28名受试者存在左侧半球偏瘫，所有受试者原本均为右利手。所有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，遵照电脑屏幕上的指示完成任务。试验开始时，一张带有文字说明、用于提示左右手动作的图片将展示2秒。我们要求受试者专注于被指定的手部运动想象任务，与此同时，电脑屏幕将播放对应同侧手部的运动视频，时长为4秒。随后将进行2秒的休息环节。
