Most often training is non-existing Travelling to and from clinics is tiring and expensive VR – 3D & Haptic Assessment and Training with Telemedicine Communication at HOME might be engaging/fun and effective for Rehabilitation? Individualized training with “serious-games” and engaging activities should be employed The system must be simple to handle and inexpensive Systems should be net-working and have video/audio communication © MR

CP, TBI, etc. 9)Correlate Kinematic outcome of Rehabilitation with fMRI (discussions with colleagues at Stanford University).
