In addition to the controlled studies, a number of FC users have become independent or they have learned to type with only intermittent physical support. The most dramatic example of independence is Sharisa Kochmeister. Evaluated as having an IQ of 10, Sharisa has no speech, and prior to FC, had demonstrated no literacy skills. After several years of FC, Sharisa now types completely independently with her father sifting behind her. Through her typing, Sharisa expresses complex thoughts and ideas.
Some studies seem to indicate that facilitated communication works.
Others conclude that no users can author their own communication. Both Cardinal and Ramsden have demonstrated the importance of practice with the specific experimental protocol is essential for success. Experiments were usually single time and place studies. Experimental protocols were not tested. When FC users failed a test researchers assumed it was the person's failure and not a problem with their test.
