The Luke arm excelled in other ways, though. "The grip strength is amazing and it’s very durable," said Giuffria. "I know for a fact I dropped the DEKA arm a couple times and it was fine." Most importantly, the Luke hand has flexion and extension, meaning the wrist can pivot the hand up and down. "After getting used to it, the flexion and extension was amazing to me," she said. "I really liked the arm." Giuffria is taking part in another DEKA clinical trial and is excited to see the arm continue improving.
