Dr. Kerry Weaver's reason for using a cane was never specified until the episode "Just As I Am" (#11.14, first aired on February, 10 2005), in which she meets her biological mother for the first time and informs her that the limp is due to a birth defect called congenital hip dysplasia.
Frances Fisher, who plays Kerry Weaver's mother, is only 5 years older than Laura Innes. Frances was born in 1952 and Laura was born in 1957.
Sissy Spacek was originally cast to play the long-lost birth mother of Dr. Kerry Weaver. At the last minute, she dropped out due to a "scheduling conflict" and she was replaced by Frances Fisher.
The title is a reference to the hymn "Just As I Am." The choir that includes Kerry Weaver's mother is singing this hymn when Kerry enters the church.
The title is based on the book 'Just as I Am', the 1997 autobiography of the Reverend Billy Graham.
