In the early 1970s, Spoorenberg was injured in a car accident, in which her rib cage was crushed. After six months in hospital, she trained intensively to restore her breathing technique. The accident influenced her decision to work closer to home and she became mainly a singing teacher. From 1970 to 1977, she taught at the Royal Academy in Brussels, and from 1971 to 1988 in the Sweelinck Academy of Music in Amsterdam. After 1978, she worked as a private teacher.[citation needed]
