Objective:Compare the non-verbal communication of children before and during interaction
with clowns and compare their vital signs before and after this interaction.Methods:Uncontrolled, intervention, cross-sectional, quantitative study with children
admitted to a public university hospital. The intervention was performed by
medical students dressed as clowns and included magic tricks, juggling, singing
with the children, making soap bubbles and comedic performances. The intervention
time was 20min. Vital signs were assessed in two measurements with an interval of
1min immediately before and after the interaction. Non-verbal communication was
observed before and during the interaction using the Non-Verbal Communication
Template Chart, a tool in which non-verbal behaviors are assessed as effective or
ineffective in the interactions.Results:The sample consisted of 41 children with a mean age of 7.6±2.7 years; most were
aged 7-11 years (n=23; 56%) and were males (n=26; 63.4%). There was a
statistically significant difference in systolic and diastolic blood pressure,
pain and non-verbal behavior of children with the intervention. Systolic and
diastolic blood pressure increased and pain scales showed decreased scores.Conclusions:The playful interaction with clowns can be a therapeutic resource to minimize the
effects of the stressing environment during the intervention, improve the
children's emotional state and reduce the perception of pain.
