Interventions
Reach training will be accomplished using an Oculus Rift and Touch 3D headset. Active markers will be placed on the shoulder, elbow, wrist, and finger in order to capture limb movement in real time. During each training session, participants will first be familiarized with the task and then will reach from a home position to 4 virtual targets that are presented in the front of the participant and within the workspace where most natural arm movements are performed.Targets will be presented in a pseudorandom order and participants will reach a total of 400 times
