Schnuth indicated that fear and apprehension might be reduced by the encouragement of questioning by the patient. It may also be useful to allow patients to touch instruments and to explain their action as some patients rely on senses other than sight to mentally visualise objects. A clear ongoing description on what they will feel, hear, taste and smell is important to ensure the patient is not surprised by an unexpected feeling, sound or taste. Movements should be explained and then carried out in a slow and deliberate manner.1
