With CUREO®, patients experience embodiment through a biomechanical avatar in virtual reality. But what exactly does "embodiment" mean? In this installment of our "CUREosity Explains" series, we explore the concept of embodiment, its neurophysiological foundations, and its application in modern rehabilitation therapy using virtual reality (VR).
Embodiment refers to the conscious perception and integration of one's body into the self-image. This bodily self-awareness is crucial for psychological well-being and motor function.
Our body image is formed through the processing of sensory stimuli—such as visual and auditory impressions—and motor activities. These interactions create neural patterns in the brain, forming an "internal map" of our body and surroundings. This map is essential for movement coordination and adapting to the environment.
The close connection between sensory input, motor function, and internal mapping highlights the importance of their seamless interaction for smooth body perception and control. If any of these components are disrupted, it can have far-reaching consequences for overall motor control.
A lack of sensory input can lead to impaired motor functions and a distorted body image. Affected individuals may struggle to apply pre-existing movement patterns. In many cases, pain arises as the brain processes incorrect or incomplete feedback, causing movements to feel uncomfortable or even painful.
Patients with hemiparesis or neglect following a stroke often experience reduced motor function due to a lack of sensory feedback from one side of the body. This interruption in information processing can lead to difficulties with posture, balance, and targeted movement execution. In many cases, the affected side is no longer perceived as part of the body.
Traditional therapy methods often struggle to restore the interaction between sensory input, motor function, and internal mapping efficiently. Patients must relearn how to connect their bodily responses and develop alternative movement patterns. Unfortunately, not all patients have access to such therapies, forcing many to adjust to their limitations.
CUREO® takes an innovative approach to rehabilitation therapy by leveraging virtual reality to enhance the embodiment experience for patients. Through the representation of a biomechanical avatar in a virtual environment, patients can rediscover their body and identify with their movements in a more natural way.
The virtual avatar mirrors the patient’s movements in real time, creating an immersive body perception. This strengthens the conscious awareness of one's own body, aiding in the restoration of motor functions.
CUREO® provides multisensory feedback—visual, auditory, and partially haptic—as well as precise motion tracking for effective sensorimotor feedback. Patients learn to coordinate their movements and reintegrate them with their environment.
Developing a New Body Image with CUREO®
As the first immersive and interactive VR therapy system, CUREO® allows for the individual adjustment of body and environmental perception to suit the patient’s specific needs. The system facilitates the gradual reintegration of neglected body areas, promoting the development of a new, healthy body image.
A key feature of CUREO® is the avatar-based mirror therapy, where patient movements are mirrored in the virtual environment. This method, based on the well-established principle of mirror therapy, can not only improve body perception but also alleviate pain.
The combination of embodiment and the wide range of patient-specific exercises with CUREO® supports the harmonious interaction of sensory input, motor function, and internal mapping. This leads to improved self-awareness and enhanced well-being in the long run.
Conclusion
Embodiment is an essential component of modern rehabilitation, particularly for patients with neurological impairments. Through the targeted use of virtual reality, CUREO® offers an innovative way to strengthen the embodiment experience and enhance rehabilitation outcomes.
By combining immersive virtual reality, precise motion tracking, and targeted sensory feedback, CUREO® presents a promising addition to traditional therapy, offering patients a new, innovative approach to rehabilitation.
