Manual Material Handling Dataset for Biomechanical and Ergonomics Analysis.

This dataset contains fully labeled motion and surface electromyography (sEMG) data captured during Manual Material Handling (MMH) and isokinetic activities. The data are collected in a laboratory environment with a commercial full-body motion capture system, and an sEMG device previously developed in the laboratory. The muscular activity is collected from both arm extensors (triceps and extensor digitorum) and flexors (biceps and brachioradialis). Fourteen subjects were recruited, and each participant performed 37 trials organized in two sets: the MMH set contains 21 actions of lifting, lowering, and carrying different loads in bimanual and one-handed modes; the isokinetic set contains 16 one-handed loads lift actions performed with different angular velocities (60, 90, 120 °/s). The handled loads are 2, 8, and 12 kg for the bimanual and 2 and 4 kg for the one-handed trials. Three human annotators were involved in the labeling. The first manually labeled the actions of all the trials, and the other two revised the annotations. For the sEMG data, two Matlab files (.m) to process the sEMG data are provided. In addition, a Matlab Live Script Editor to download, import, and process the data is available at the following GitHub link. The motion data are provided in a proprietary format, sEMG data, labels, and subject information in csv format. If you use the dataset you are kindly asked to cite the paper "<em>G. Bassani, A. Filippeschi and C. A. Avizzano, "A Dataset of Human Motion and Muscular Activities in Manual Material Handling tasks for Biomechanical and Ergonomic Analyses.", in IEEE Sensors Journal, DOI: 10.1109/JSEN.2021.3113123"</em> where a detailed description of how the data were collected is available.本数据集包含经完整标注的人体运动与表面肌电（surface electromyography, sEMG）数据，采集场景涵盖手动物料搬运（Manual Material Handling, MMH）与等速运动两类活动。数据采集于实验室环境，采用的设备包括商用全身运动捕捉系统，以及本实验室此前自主研发的肌电采集装置。肌肉活动数据采集自手臂伸肌（肱三头肌、指伸肌）与屈肌（肱二头肌、肱桡肌）。本研究共招募14名受试者，每位参与者完成37组试验，分为两个试验集：手动物料搬运试验集包含21项动作，涵盖双手、单手模式下举升、下放与搬运不同负载的操作；等速运动试验集包含16项单手负载举升动作，分别以60、90、120 °/s的角速度完成。搬运负载参数如下：双手模式下为2、8、12 kg，单手模式下为2、4 kg。本数据集的标注工作由三名人工标注员协作完成：第一名标注员对所有试验的动作进行手动标注，另外两名标注员对标注结果进行复核。针对表面肌电数据，提供了两份用于处理肌电数据的Matlab脚本文件（格式为.m）。此外，可通过以下GitHub链接获取用于下载、导入与处理数据的Matlab实时脚本编辑器。运动数据以专有格式存储，肌电数据、标注标签与受试者信息则以csv格式存储。若使用本数据集，请务必引用论文<em>"G. Bassani, A. Filippeschi and C. A. Avizzano, "面向生物力学与人体工效学分析的手动物料搬运任务中人体运动与肌肉活动数据集"，发表于IEEE Sensors Journal，DOI: 10.1109/JSEN.2021.3113123"</em>，该论文中详细说明了数据采集的具体流程。
