Using gestures simultaneously with speech prevents and solves problems of understanding in consultations where the doctor and the patient do not share the same cultural and linguistic background. Gestures illustrate what is being said, and highlight the essential information. As gestures are used globally, and can also be interpreted despite limited vocabulary, they make the speech easier to follow. In primary care consultations, the topics are easily expressed by gestures, as they are often related to physical matters such as body parts, symptoms, examinations and treatment. Furthermore, gestural mimicry conveys empathy and willingness to collaborate.
