Bionics: What's Behind

Inail Direzione centrale assistenza protesica e riabilitazione (INAIL) --- ITALY

Despite the advances in robotics and mechatronic made available high performance prosthetic devices, the state of art of prosthetic control has yet not evolved enough for developing fully integrated Bionic systems. Nevertheless, Inail and its research network are currently investigating this field aiming to fuse in harmony the robotic technology and the human body. Indeed, exploiting artificial intelligence algorithms and innovative surgical techniques it has been possible to achieve simultaneous multi-limb control and restore the natural sensory feedback. Here we present the latest result of our research activity in this field showing that bionic prostheses represent a not so distant future.

Restoration of Hand Function Using Cognitive Nerve Transfers to Control Bionic Limbs

Medical University of Vienna --- AUSTRIA

Despite major improvements in primary prevention and acute treatment over the last decades, stroke is still a devastating disease and major cause of adult disability. Randomized controlled trials demonstrate the safety and efficacy of nerve root transfers for treatment of spastic arm paralysis after chronic cerebral injury. Here we present our first experience to restore hand function in patients with chronic spasticity after brainstroke using selective nerve transfers and EMG driven cognitive control of bionic limbs. This treatment has the potential to be a real game-changer in this particular patient group.

Towards a smart and intuitive controlled leg prosthesis: acquisition of intramuscular electromyography for motion intention detection. A pilot study.

Roessingh Research and Development --- THE NETHERLANDS

This pilot study explores the use of intramuscular EMG (iEMG) and targeted muscle reinnervation (TMR) to improve motion intention detection in transfemoral amputees. The hypothesis is that iEMG will improve intention detection because of reduced crosstalk and more consistent electrode sites. The TMR sites will provide valuable extra information for motion intention detection. Methods: A study population of able-bodied individuals (n=5), transfemoral amputees (n=5), and transfemoral amputees with TMR (n=5) will be included in this observational study. During the measurements iEMG (fine-wires), sEMG (multi-array) and lower body kinematics are measured while participants execute activities like sitting down, walking on uneven terrain, and stair/ramp ascend/descend. Results: Preliminary results will be presented.

Shared Control of a Robotic Arm using Brain-Computer Interfaces and Robotic Vision

University of Bath --- UNITED KINGDOM

The brain-computer interfaces (BCIs) based on non-invasive electroencephalography (EEG) have been widely used. However, the low-quality of EEG signals may cause problems of poor decoding accuracy and low control dimension, which adversely affects the performance of non-invasive BCIs during real-time process control in complex tasks. In this work, a brain-actuated robotic arm system based on shared control was developed, which allowed noninvasive BCI users to manipulate a robotic arm with six degrees of freedom moving in a three-dimensional (3D) space and complete a pick-and-place task of multiple objects. We introduced a hybrid BCI scheme that integrated motor imagery and steady state visual evoked potentials to raise the control dimension of the robotic arm.

HyDRA-Walker project: a robotic walker guide for powered exoskeletons with neural interface

Department of Information Engineering, The University of Padova --- ITALY

Powered lower-limb exoskeletons represent a recently emerging technology in the field of wearable robotics, enabling paraplegic people to walk again. However, their use is still restricted to clinical settings or controlled environments. To overcome this limitation, herein we present the HyDRA-Walker project, about the development of a robotic walker that will act as an intelligent guiding agent to control brain-actuated exoskeletons in daily-living situations. We further present our latest advancements on a hybrid brain-computer interface (h-BCI) for walking decoding. Finally, we introduce future insight on how this interface will be adopted to control the powered exoskeleton in our project.

Feel Your Reach: Continuous robotic arm control by non-invasive EEG signals

Graz University of Technology, Institute of Neural Engineering, BCI-Lab --- AUSTRIA

Decoding intended movements from individuals with spinal cord injury (SCI) has been a central topic in brain-computer interface research for decades. Recent works, relying on neural spiking activity, demonstrated that the kinematics of intended movements can be detected and used by individuals with SCI to control end-effectors. In this work, we summarize our attempts towards realizing an EEG-based movement decoder. We summarize our efforts to address this topic from various perspectives, and we present results of a single case study with a non-disabled participant, where we decoded the intended movement trajectories, while the participant’s arm was fixed.

Unlocking Independence: How BCI can be used to increase access to power mobility and independent movement

University of Calgary --- CANADA

Children with severe physical disabilities could drastically benefit from access to powered wheelchairs and other power mobility devices (PMDs) to enable their independence and participation. However, these children are often ineligible for PMD funding if their severity of disability prevents them from operating traditional access methods like joysticks or switches. Brain-computer interfaces (BCI) are a promising alternative access method for these children but has seen limited clinical translation. We have developed a modular, affordable, and easy-to-use BCI-enabled PMD using a commercial-grade headset that can be used by therapists in a clinical setting to explore power mobility with severely disabled children.

Learning to drive a brain-actuated intelligent wheelchair

Department of Information Engineering, Università degli Studi di Padova --- ITALY

Among the several brain-actuated neurorobotic prototypes, brain-machine interface (BMI) driven wheelchairs represent the paramount promise for people suffering from severe motor disabilities thanks to the applicability in complete paralysis. Herein, we present the latest experimental results where three tetraplegic spinal cord injury users learned to control a non-invasive, self-paced BMI-driven wheelchair and execute complex navigation tasks in real-world surroundings. We further substantiate that user's learning and robotic intelligence are the two cornerstones for developing robust and effective BMI translational applications. Finally, we introduce the next directions of our research to promote human-machine learning interactions in brain-controlled neuroprostheses.

EASY Walk: EEG Driven Walking Rehabilitation with Exoskeletons

INDI Ingenierie et Design --- FRANCE

Current clinical rehabilitation with exoskeletons faces important shortcomings: a 'one fits all' approach, limited occupational tasks, and an inadequate quantification of expected outside-of-hospital performance. Easy WALK proposes an Ambulatory, Mobile encephalography(EEG)-Amended Platform which adds robotic support and mental-workload assessment capabilities to occupational rehabilitation. Training is made possible in hospital and outdoors, allowing to 1) better tune rehabilitation techniques and 2) improve on outside-of-clinic results. This work focuses on integrating such workload-focused mobile BCI devices to pediatric exoskeletons and on improving the rehabilitation process in clinic and exoskeleton usage in outside environments, especially for children and early life-quality improvement.
