Schiffler and two other team members are competing for the first time in the Paralympic Games. Her husband, Alexander, is on the German men's sitting volleyball team.
Schiffler was born with a deformed right arm. She wears her prosthetic arm while playing volleyball and basketball. The rest of the time, she said, she prefers not to wear it because it is hot and she feels more normal without it.
Erickson lost her leg after a broken bone in her leg would not fuse back.
Miller and Erickson will not wear their prosthetic legs in the games.
The USA sitting volleyball team, coached by Bill Hamiter, could play up to five games. The first game is at 10 a.m. Aug. 31 against China, the team that won the gold in 2008.
Hanson, a member of the U.S. Olympic Committee, traveled with the volleyball team to China but this time will watch from afar.
“They are a great group of girls,” Hanson said. “They have prepared every day and worked hard.”
