Process of systematic desensitisation
1) Patient is taught how to relax their muscles completely. (a relaxed state is incompatible with anxiety).
2) Therapist and patient together construct a desentitisation hierarchy.
3) Patient gradually works their way through desensitisation hierarchy, visualising each anxiety-evoking event while engaging in the competing relaxation response.
4) Once the patient has mastered one step in the hierarchy (i.e. they can remain relaxed while imagining it) they are ready to move onto the next step.
5) Patient eventually masters the feared situation that caused them to seek help in the first place.
