DB1 Guidelines
Overview
This Ninapro dataset includes sEMG and kinematic data from 27 intact
subjects while repeating 52 hand movements plus the rest position.
Publications
The dataset is described in detail in the following scientific papers.
Please, refer to them for detailed guidelines and cite them in case you
use this dataset.
Instructions
Subjects
27 intact subjects.
Acquisition Setup
The sEMG data are acquired using 10 Otto Bock MyoBock 13E200 electrodes,
while kinematic data are acquired using a Cyberglove 2 data glove.
Acquisition Protocol
The dataset includes 10 repetitions of 52 different movements. The
subjects are asked to repeat movements which were shown as movies on the
screen of a laptop.
The experiment is divided in three exercises:
- Basic movements of the fingers.
-
Isometric, isotonic hand configurations and basic wrist movements.
- Grasping and functional movements.
Dataset variables
For each exercise, for each subject, the database contains one matlab file
with synchronized variables. The variables included in the matlab files
are:
- Subject: subject number.
- Exercise: exercise number.
-
Emg (10 columns): sEMG signal. Columns 1-8 are the electrodes equally
spaced around the forearm at the height of the radio humeral joint.
Columns 9 and 10 contain signals from the main activity spot of the
muscles flexor and extensor digitorum superficialis.
-
Glove (22 columns): uncalibrated signal from the 22 sensors of the
cyberglove.
The cyberglove signal corresponds to raw data from the cyberglove
sensors, which are expected to be proportional to the angles at the
joints.
-
Stimulus (1 column): the movement repeated by the subject, according
to the displayed movie.
-
Restimulus (1 column): the movement repeated by the subject, but with
the duration of the movement label refined a-posteriori in order to
better correspond to the real movement.

for more details about relabelling procedure.
- Repetition (1 column): repetition of the stimulus.
- Rerepetition (1 column): repetition of restimulus.
Acquisition procedure: the subjects are asked to mimic movies of movement
shown on the screen of the laptop; sEMG signal is recorded with 10
electrodes (red, blue; the electrode on the flexor digitorum superficialis
and part of the equally spaced electrodes are not represented due to
perspective reasons).
Hand movements. Performed exercises: A, B, C.
