iLAST: Immmersive Leg Coordination and Strength Therapy

This project is already completed.

Background

The results of this project are summarized on the webpage of the project group.

Knee injuries are a major cause for mobility deficits and can drastically impair people. Typical knee traumata can occur during sport activities as well as in house hold and every day life actions. Knee injuries often include permanent damages to internal knee structures necessary for accurate motor functions. These include, e.g., ligament and/or meniscus ruptures as well as cartilage damages.

Two major types of treatment solutions exist for knee injuries: (1) conservative (non-invasive) as well as (2) invasive surgery-based methods to initially repair damaged areas. In both cases, coordination and strength exercises are a central aspect of conservative as well as of post-surgery therapy. Knee mobilization is important to establish correct motor function and to detumescence post-traumatic liquid conglomeration. Increasing muscle strength helps to stabilize the knee and to protect the knee from further damages. Motivation to perform repetitive exercises is a crucial necessity for a positive outcome. Similarly, control, regulation, and adaption to the patients progress is required for maximum efficiency and effectivity.

Tasks

This project develops an immersive Virtual Reality (VR) training system for post-operative therapy treatment after knee injuries. The training system uses basic game-like experiences simulated in fully immersive virtual environments which motivate patients to perform dedicated movement tasks mobilizing and strengthening their lower limbs.

Patients will be partly embodied. They will be able to see a virtual counterfeit of their injured leg which will interact with virtual objects, e.g., balancing a virtual ball or retracing a specified task, to increase motor mimicry and to strengthen the training effect. Game-like mechanics will be used to motivate patients and to adopt the training level to the personal progress.
