  1. The Tetraplegiac Neuroprosthetic By Robert Valenti

  2. What is Tetraplegia? • Also known as quadriplegia • Paralysis caused by illness or injury • Partial or total loss of all one’s limbs and torso • Loss of sensation and control of limbs

  3. The Neuroprosthetic Arm • Seven degrees of freedom • Has three dimensional translation, three-dimensional orientation, and one dimensional grasping • Reinstates command signals for hand placement • Increases quality of life

  4. Installation • Surgery • Two 96-channel intracortical microelectrode implants, called the “Braingate”. • Motor cortex

  5. Results So Far • Arm movement with only two days of training • Advanced movements after 13 weeks of training • Massive increases to quality of life • Ineffective with subjects who have viable limbs

  6. What the Future Holds • Possible availability within 5 to ten years • Feedback so a person can interpret sensations, like the pressure of a grip • The world of brain-to-computer interface will explode
