EEG and EMG data of a force control task

This dataset is used to verify the effectiveness of the proposed MS-caCOH method.Subjects sat comfortably in an armchair and were instructed to carried out a force control task, with left arm placed along the body and right arm put on the table naturally. Prior to the experimental sessions, each subject measured the maximum voluntary contraction (MVC), and the corresponding maximum preset force was defined as 20% MVC. A single trial lasted 12 seconds, consisting of 3-second preparation stage, 6-second force control task and 3-second rest stage. For each subject, we acquired four runs of data and each run was made up of 30 trials. To mitigate muscle fatigue effects, 3~4 seconds of rest interval was provided between two consecutive trials and 3 minutes of rest was provided between runs. Throughout the experiment, subjects were instructed to focus attention on the force control task and avoid redundant movements.

本数据集旨在验证所提出的MS-caCOH方法的有效性。受试者在舒适的扶手椅中就坐，并被指示执行一项力控制任务，其中左臂沿身体放置，右臂自然置于桌面上。在实验会话之前，每位受试者均测量了最大随意收缩（MVC），相应的最大预设力被定义为20% MVC。单次试验持续12秒，包括3秒的准备阶段、6秒的力控制任务和3秒的休息阶段。对于每位受试者，我们收集了四次数据运行，每次运行由30次试验组成。为减轻肌肉疲劳的影响，在连续两次试验之间提供了3至4秒的休息间隔，并在运行之间提供了3分钟的休息时间。在整个实验过程中，受试者被要求集中注意力在力控制任务上，并避免不必要的动作。
