EMG dataset for the article titled: "Designing for Practicality: A Personalized and Adaptive Framework for Real-Time EMG-Based Hand Motor Decoding"

This dataset was collected for the research article titled: "Designing for Practicality: A Personalized and Adaptive Framework for Real-Time EMG-Based Hand Motor Decoding". It comprises electromyography (EMG) signals recorded from twelve healthy participants performing nine distinct hand motions. Participant information, including gender, age, weight, and height, is provided in a separate file named "dataset_info.xlsx". To provide temporal context for the EMG data, four key timestamps, extracted for each trial from synchronized video recordings (s4_fist_r2.mp4), are included as well to represent the kinematic data.See the paper for more details: https://doi.org/10.1088/1741-2552/adbfbfDataset StructureThe dataset is organized within the file "dataset.zip". Each subject's data resides in a separate folder. Subjects 11 and 12 participated twice, resulting in duplicate folders for them.Subfolder ContentEach folder contains 180 files named "motion_repetition.mat". These files represent individual trials where a subject performed a specific hand motion. Repetitions range from 1 to 20, and motions include:FistFist_PoweredAll_Fingers_ExtensionPinchThumb_FlexionAbductionV_SignPointThumbs_UpData File Content (.mat files)Each ".mat" file contains four key variables:- Muscle Data (m1, m2, m3):Three separate 8000x1 vectors represent the EMG signals of these three muscles, sampled at 1000Hz:m1: Abductor Pollicis Longus (APL)m2: Extensor Digitorum (ED)m3: Flexor Digitorum Superficialis (FDS)- Time Stamps (T):A 4x1 vector, extracted from the videos, containing timestamps (in seconds) for four specific events:Rest-to-Action Transition: The point where the hand starts moving from a resting position.Action Onset: The beginning of the actual hand movement.Action Offset: The end of the hand movement and the start of the transition back to rest.Return to Rest: The point when the hand reaches a complete and steady state of rest.
