Bryan Stow, the San Francisco Giants fan who was brutally beaten on Opening Day at Dodger Stadium, can lift his arms and legs and respond to commands, his family said on their website.
"He lifted his left leg slightly when asked, he raised his left arm everytime we asked if we could hold his hand," the site said.
The site said the "best part" was when Stow's sister Bonnie asked if she could give him a kiss and "every time she asked him, he puckered his lips."
Stow remains in a San Francisco hospital. He suffered brain damage in the near-fatal assault and had been in a coma. He experienced a setback in his recovery last month when he underwent emergency brain surgery after suffering a 30-second seizure.
The news comes on the same day that the two men accused of beating Stow pleaded not guilty to criminal charges in Los Angeles.
Louie Sanchez, 29, and 30-year-old Marvin Norwood have been charged with mayhem, assault, battery and other counts.
