Related to systematic desensitisation: aversion therapy
A type of behavioural intervention for managing phobic disorders, in which the therapist has a client focus on his or her worst fear or aversion, while encouraging him or her to relax. The repeated cycling of tension and relaxation is meant to desensitise the client to the stressful stimulus, and can also be used for anticipatory side effects (e.g., nausea associated with chemotherapy). A common format of systematic desensitisation consists of muscle relaxation coupled with visualising each of a hierarchy of anxiety-provoking stimuli, ranging from the least to most unpleasant.
