EMG data for Falling Heads: investigating reflexive responses in active Human Body Models

This dataset contains the raw electromyographic (EMG) data for 17 participants of the Falling Head experiment of the paper "’Falling Heads’: investigating reflexive responses to head-neck perturbations" by Isabell Wochner, Lennart V. Nölle, Oleksandr V. Martynenko and Syn Schmitt. Always cite the paper together with this dataset because this dataset is not self-explanatory. Muscle activation was monitored using surface EMG of the right and left sternocleidomastoideus (SCM) muscle and the trapezius muscle. The EMG activity was recorded at 1000 Hz using myoResearch software (Noraxon/USA). The placement of the electrodes at the trapezius muscle was done according to SENIAM guidelines [1]: The electrode pair was placed in the middle of the line between the spinous process of the 7th cervical vertebra and the acromion. The electrodes for the sternocleidomastoideus (SCM) muscle were placed over the middle part of the SCM muscle according to [2]. All electrodes were attached parallel to the muscle fibre orientation at a distance of 20 millimetres. The reference electrode was fixed on the acromion. Volunteers were asked to relax their muscles before the onset of the movement. The trigger signal (at the onset of the movement) was set by a hardware trigger (by braking the power circuit). Furthermore, the demographic characteristics (gender, age, weight, height and BMI) are provided as .txt file. [1] Hermens, Hermie J., et al. "European recommendations for surface electromyography."

本数据集收录了论文《‘Falling Heads’：探究对头部-颈部干扰的反射性反应》中‘Falling Head’实验的17名参与者的原始肌电图（EMG）数据。该论文由Isabell Wochner、Lennart V. Nölle、Oleksandr V. Martynenko和Syn Schmitt共同撰写。在使用本数据集时，请务必引用该论文，因为该数据集本身并不具有自解释性。肌电图数据是通过测量左右胸锁乳突肌（SCM）和斜方肌的表面肌电图（sEMG）来记录的。记录的肌电图活动频率为1000赫兹，使用myoResearch软件（Noraxon/USA）进行记录。斜方肌上的电极放置遵循SENIAM指南[1]：电极对放置在第七颈椎棘突与肩峰之间连线的中点。胸锁乳突肌（SCM）的电极放置在SCM肌的中间部分，具体方法参照[2]。所有电极均与肌纤维方向平行，距离肌纤维20毫米。参考电极固定在肩峰上。志愿者在运动开始前被要求放松肌肉。运动开始的触发信号（硬件触发，通过断开电源电路）被设置。此外，志愿者的人口统计学特征（性别、年龄、体重、身高和BMI）以.txt文件形式提供。[1] Hermens, Hermie J.等.
