Each subject will receive an experimental intervention of exclusively 500 grams of crushed ice. The intervention will last 20 minutes, and the order of application, expressed in % of water X ice, will be according to the randomization (realized in the first day). The pack will be wrapped in a band for improvement of the contac area. The subject will be asked to mark his pain level on the visual analogue scale (no pain score of 0 and pain as bad as it could be score of 10) every minute until the total time of the intervention.

Each subject will receive an experimental intervention of ice pack added to 50 mL of water.
