Description

Motivation and application domain
Body-machine interfaces (BMIs) decode upper-body motion for operating devices, such as computers and wheelchairs. In the last decades, body machine interfaces have been developed as tool to investigate neural control of movement and/ or to empower disabled people to reach assistive and rehabilitative goals. BMI based on body movement have been proved effective to support personalized a therapy for survivors of cervical spinal cord injury (cSCI).

General objectives and main activities
Aim1: Developing the technology for a hybrid human-machine interface based on mapping body motion sensors and EMG signals onto a variety of control tasks. The combination of EMG and movement signals will be mapped to the lower-dimensional motion of the external device via linear and nonlinear methods.
Aim 2: Assessing the activation and/or deactivation of targeted muscles and muscle synergies through a movement and EMG analyses.
Aim 3: Buinding a map between body space and control space of the machine that takes into account the time history of the body signals.
The study will begin with a control subjects, but will be tested also in stroke survivors and/or spinal cord injury subjects

Training Objectives (technical/analytical tools, experimental methodologies)
The student will learn
- To analyze and correlate body signals from different sources such as movement and EMG
- To develop the control of an external device based on body signal coming from different sources
- to develop data analysis tools for behavioral data
- to improve the knowledge of Matlab/Simulink, machine learning algorithms (e.g. auto encoders networks) and statistical analysis
- to work in an international team with people with different backgrounds and with people with disability


Place(s) where the thesis work will be carried out: DIBRIS department of the University of Genova.
