A Patient-Driven Augmented Reality-Based Rehabilitation System to Improve Upper Limb Amputee Outcomes

MyoTrain AR is a virtual prosthesis functional training system. From a hardware perspective it consists of an augmented reality head-mounted display (HMD), four SteamVR kinematic trackers, eight surface EMG electrodes based on the Element electrode platform, and a desktop computer to facilitate wireless communication between the various hardware components. From a software perspective, MyoTrain AR was developed in the cross-platform Unity 4.0 game development engine.

Motor imagery describes the process by which a prosthesis user mentally simulates the execution of a desired limb movement and activates the musculature of the residual limb that would generate the desired movement.
