It is expected to find statistical differences between the experimental groups and the control groups in their respective points, for the sensation of penetration of the self‐reported needle by the volunteer after intervention from the application of the post‐intervention questionnaire. These data will be observed from the value of p <0.05, with a 95% confidence interval.
