Projektbeschreibung
Virtuelle Realität zur Rehabilitation der oberen Extremitäten nach Schlaganfall
Alle 20 Sekunden erleidet ein Mensch in Europa einen Schlaganfall, der die weltweit zweithäufigste Todesursache und dritthäufigste Ursache für von Behinderung geprägten Lebensjahren darstellt. Ein wichtiges therapeutisches Ziel ist nun, die motorische Rehabilitation der oberen Extremitäten nach einem Schlaganfall zu verbessern. Das EU-finanzierte Projekt ImpHandRehab baut auf der Erkenntnis auf, dass belohnungsbasierte Interventionen das motorische Lernen bei Schlaganfallpatienten mit gestörter Funktion der oberen Extremitäten optimieren können. Dabei soll demonstriert werden, dass Technologie auf Basis virtueller Realität (VR) ein wirksames Rehabilitationsinstrument sein kann. Insbesondere erfasst ein VR-kompatibles Motion-Capture-System in Form eines Handschuhs ohne Kamera detaillierte Positionsdaten der einzelnen Finger. Ziel des Projekts ist ein erschwingliches, flexibles, genaues, interaktives und wissenschaftlich validiertes handbasiertes Rehabilitationsprodukt für die häusliche Verwendung.
Ziel
The ERC proThe ERC project (MotMotLearn), underlying ImpHandRehab, aims to develop reward-based interventions that optimise motor learning in stroke patients suffering upperlimb impairments. MotMotLearn has shown that if reward-based feedback is combined with a distracting environment learning is robust to interference and resistant to forgetting; important components for a successful rehabilitation intervention. However, this work has highlighted several technical limitations which restrict our ability to apply this knowledge to stroke patients. First, an engaging virtual reality (VR) environment is required that enables reward-based feedback to be combined with distracting environments. Second, many stroke patients exhibiting upperlimb impairment are unable to open their hand (finger extension). Not only does this limit participation in rehabilitation programs but also restricts functional use of the arm. Crucially, existing hand-based VR-related equipment has at least one of the following issues; limited ability to measure individual finger movements, requires the hand to be in close proximity to a camera or is prohibitively expensive. Therefore, a clear gap exists for a sensitive, flexible and affordable VR-based product that focuses on hand function recovery. To address this, ImpHandRehab will use a state-of-the-art VR-compatible motion capturing glove which accurately collects individual finger position data without the need for a camera. Several VR tasks will be developed that focus on improving finger extension (whole hand and individual fingers) through the combination of closed-loop reward-based learning designs and distracting environments. These tasks will be optimised in healthy older adults and validated in stroke patients via the UK’s largest upperlimb rehabilitation clinic. ImpHandRehab will create an affordable, flexible, accurate, interactive and scientifically-validated hand-based rehabilitation product which patients will be able to use at home.
