Patients were invited to participate in the study from phone calls. They were recruited from the service list in Neurology at Hospital Onofre Lopes, in Natal -Brazil. Randomization of individuals with respect to participation in the groups was done via the randomization.com website, by a person unfamiliar with the training procedures (rater 1), who assigned a color (yellow or green) to each group. Opaque envelopes were numbered and separated, and inside each envelope was a piece of paper containing the word "yellow" or "green". As a new patient arrived for training, rater 2 opened an envelope and was only aware of the color code of that particular patient. Rater 3, the lead researcher, conducted the assessment and re-assessment procedures. The color codes were maintained in secrecy by raters 1 and 2 throughout the entire study.
