the median nerve flexor region to control hand closing, and the median nerve thumb
abductor region to control hand opening. Fitted with a sophisticated artificial arm that
interfaced with the pectoral muscle group shown in Figure 10-54, Sullivan was able to
operate his elbow, wrist, and terminal device simultaneously with greater ease and speed
than he could previously (MacIsaac and Englehart, 2006).
In 1995 Dr Kuiken's bionic arm project at RIC was publicly unveiled when Sullivan
began using a six-motor version of the arm that provided more dexterity than the original
prosthesis. It was also the year that Claudia Mitchell became the first female to receive the
TMR surgery (Kuiken, Miller et al., 2007). A total of 3 months after the surgery, she started
to feel the reinnervation taking effect. When she thought about squeezing her nonexistent
hand she could tell that her chest muscles were working, and when the patch of skin on
