Mr Hesseltine was employed as a psychiatric assistant at the Lake Alice Child and Adolescent Unit starting in 1974 and ending in 1979. He discussed his role in the unit, and the daily routine and activities of patients and staff at the hospital. Additionally, Mr Hesseltine offered his recollections on witnessing different procedures, including what Dr Leeks told him was a procedure called “Ectonus therapy” as a behavioural modification therapy being used for child patients in the unit.
