## Description ## SEEDS contains electromyographic (EMG) signals and hand kinematics recorded from the forearm muscles of 25 non-disabled subjects while performing 13 different hand movements at normal and slow-paced speeds. Surface EMG signals were recorded with a high-density 126-channel array centered on the extrinsic flexors of the fingers and 8 further electrodes placed on the extrinsic extensor muscles. A data-glove was used to record a total of 18 angles of the joints of the wrist and fingers while the movements were performed. This database was collected as part of theDeTOP European project. ## Citation ## The authors ask that any researcher who uses these data acknowledges the paper where this database is presented: Matran-Fernandez A, Rodriguez Martínez IJ, Poli R, Cipriani C, Citi L. SEEDS, simultaneous recordings of high-density EMG and finger joint angles during multiple hand movements.

Our database allows for the extraction of the neural drive as well as performing electrode selection from the high-density EMG signals. Moreover, the hand kinematic signals allow the development of proportional methods of control of the hand in addition to the more traditional movement classification approaches. ## Acquisition Setup ## - sHD-EMG array : 126 channels - semg: 8 electrodes - kinematics acquisition device: Cyberglove III data glove. - number of movements: 13 - sessions: 3 - movement repetitions: 6 - velocities: fast and slow ## Repository Folders ## - figures: contains the figures of the synchronization between EMG and data-glove per each of the movements. - functions: contains the fucntion in MatLab and Python to work with the data - stimuli: contains the videos and images presented to the participants during the experiment - subjXX: a folder per participant (with XX number of the participant) containing the experimental data ## Data Files ## The experimental data are split into folders per subject, each filename has the format detop_exp01_subjAA_SessB_CC_DD.mat - AA: subject number (1–25) - B: session(1–3) - CC: movement (1–13) - DD: repetition number (1–6) ## Variables in the Files ## - subject: subject number - session: session number - date: date in which the data were collected, in format YYYYMMDD - movement: name of the movement performed by the subject - fs_emg: sampling frequency of the EMG recordings (2048 Hz) - fs_glove: sampling frequency of the data-glove signals (256 Hz) - speed: speed at which the movement was performed (fast or slow) - emg: 2D array (channels x samples) of sEMG signals. This array contains 134 rows, each one representing a recording site. The first 126 rows belong to the HD-sEMG array, the remaining ones are from the individual sEMG sensors placed on the posterior part of the forearm - channels_emg: contains the names of the channels for the EMG signals in the order as they appear on the data matrix - glove: 2D array (channels x samples) of signals from the 18 sensors (one per row) of the data-glove. The signals represent the normalised angle of each joint and have been normalised to be between 0–1 - channels_glove: contains the names of the channels for the data-glove in the order as they appear on the data matrix
