In May 2010, Chi Cheng began showing significant signs of improvement, and was able to track individual people with his eyes, occasionally make worded responses, and slightly move his hands. Chino Moreno stated that the Cheng family would be paying a doctor with the International Brain Research Foundation who is experienced in the field of coma and trauma patients, using funds raised through the oneloveforchi website, to use an experimental medicine to bring Chi out of his coma-like state. The treatment had an 84% success rate. In May 2011, Cheng began undergoing rehabilitation and additional operations in New Jersey.
