1. The Ninapro database

Ninapro is a publicly available multimodal database to foster research on human, robotic & prosthetic hands and on machine learning based control systems.
The database includes over 300 data acquisitions divided in 10 datasets, providing electromyography, kinematic, inertial, eye tracking, visual, clinical and neurocognitive data and targeting different research needs.
Ninapro datasets are used worldwide by scientific researchers in machine learning, robotics, medical and neurocognitive sciences.
Intact subjects can be used as a proxy measure for hand amputees (Atzori et al., EMBC 2014), however we recommend to include amputees data whenever possible.
Considering the data from amputees, several clinical parameters related to the amputation can significantly influence results, as described in Atzori et al., Journal of Rehabilitation Research and Development, 2016. This fact should be properly considered while analyzing the data and presenting the results.

Ninapro database in brief:
DB1 - Subjects: 27; Data: EMG (Delsys Trigno), kinematics.
DB2 - Subjects: 40; Data: EMG (Delsys Trigno), kinematics, inertial, force.
DB3 - Subjects: 11 transradial amputees; Data: EMG, inertial.
DB4 - Subjects: 10; EMG (Cometa electrodes), kinematics.
DB5 - Subjects: 10; Data: EMG, inertial (two talmic Myo Armbands, 16 electrodes)
DB6 - Repeatability data (2 times per day acquisitions for 5 days from 10 subjects); data: EMG, inertial, portable eye tracking glasses with scene camera
DB7 - Subjects: 20 intact subjects, 2 transradial amputees; Data: EMG
DB8 - aimed at the estimation/reconstruction of finger movement rather than motion/grip classification. Subjects: 10 intact subjects and 2 amptuees.
DB9 - Subjects: 77; Data: kinematic data acquired with a Cyberglove-II.
DB10, MeganePro - Subjects: 30 amputee and 30 intact subjects; Data: sEMG, intertial, gaze tracking, visual, behavioral and clinical data for prosthetics and the analysis of phantom limb sensation.

2. Resources, results and projects information

PaWFE
Our extremely fast signal feature extraction tool, allowing to extract the most common signal features in minutes from dozens of subjects (currently implemented for Matlab).

Quantitative taxonomy of hand grasps
The most solid representation of hand movements' hierarchy, fully based on quantitative EMG and kinematics data analysis (image below).
The taxonomy is useful for rehabilitation, robotics, virtual reality and other domains and it is published on JNER (Stival et al, JNER 2019) .
