Using virtual reality to induce cross-axis adaptation of postural control: Implications for rehabilitation

Adaptation of sensorimotor processes has been studied for over a century. However, rigorous experimental approaches require controlling as many variables as possible to study the phenomenon, which limits generalizability. Conversely testing adaptation in an unconstrained ecologically valid situation makes it difficult to identify what parameters affect this process. This study utilizes virtual environments (VE) to create complex, but controlled environments to test visual, vestibular, and sensorimotor adaptation of whole-body posture. Findings show automatic postural processes can be adapted to unusual and discordant sensory environments, suggesting its lability would be advantageous when employing the kind of sensorimotor rehabilitation therapy VE affords.
