He cannot move and needs round-the-clock care - but that did not stop Jacob Trossman having a barmitzvah.
The 13-year-old was born with Pelizaeus-Merzbacher disease, a degenerative disorder which affects the central nervous system and has left him able to communicate only through blinking.
With one blink, Jacob instruct a computer to read the blessings before and after his Torah portion in front of 120 guests at the Hospital for Sick Children in Toronto, Canada.
Rabbi Baruch Frydman-Kohl of Beth Tzedec Congregation said the event had a wider significance.
