This dataset contains high-density surface electromyography (HDsEMG) recordings from the Isometric Challenge during the MUnitQuest Familiarization phase.
MUnitQuest is a community-driven competition on motor unit identification methods. The data and metadata of each recording follow the standardized EMG-BIDS format.
This dataset contains 100 HD-EMG recordings (experimental and simulated) across various isometric tasks with a tapozoidal or triangular effort profile. Each data file (.edf) is accompanied by the following metadata files specifying the recording set-up and the task:
- electrodes.tsv: A tabular file specifying the electrode positions
- coordsystem.json: The frame of reference of the electrode coordinates
- channels.tsv: A tabular file providing a mapping from the electrode configuration to the data matrix
- emg.json: Describing the recording hardware and configuration
- events.tsv: A tabular file specifying the experimental protocol
Tutorials on how to import the EMG data provided in this dataset can be found in the MUnitQuest-Tutorial repository.
