Therapy for a singer. Speech therapist Dr. Marie- Agnes Faure (left) uses a laryngoscope to examine the vocal cords of a female singer. On the TV monitor the vocal cords appear white and parallel in the throat. They produce vibrations from the windpipe to form sound. Injury to the throat (such as nodules or oedema) can occur due to incorrect singing techniques. Speech therapy exercises the vocal muscles and corrects unhealthy singing habits, without affecting any healing process. Musicians suffer ailments associated with their profession: cramp, lumbago, arthritis, damaged vocal chords. This therapy can offer both injury rehabilitation and preventative measures.
