Outcome Measures

Primary Outcomes (1)

  • Validation of the VISIODOL® scale in screening of pain in people with visual impairment using the correlation coefficient between the intensities measured with the Numerical Scale (NS) and the VISIODOL® scale obtained by using thermal tests.

    Determination of the correlation coefficient between NS and VISIODOL® scale for different pain temperatures by hot thermal tests. The rating of the NS and VISIODOL® scales can range from 0 to 10.

    Day 0 + 2 hours

Secondary Outcomes (10)

  • Validation of the VISIODOL® scale in screening of pain in people with visual impairment using the correlation coefficient between the intensities measured with the Numerical Scale (NS) and the VISIODOL® scale obtained by using thermal tests.

    Day 0 + 2 hours

  • Validation of the VISIODOL® scale in screening of pain in people with visual impairment using the correlation coefficient between the intensities measured with the Numerical Scale (NS) and the VISIODOL® scale obtained by using thermal tests .

    Day 0 + 2 hours

  • Validation of the VISIODOL® scale in screening of pain in people with visual impairment using the correlation coefficient between the intensities measured with the Numerical Scale (NS) and the VISIODOL® scale obtained by using thermal tests.

    Day 0 + 2 hours

  • Validation of the VISIODOL® scale in screening of pain in people with visual impairment using the correlation coefficient between the intensities measured with the Numerical Scale (NS) and the VISIODOL® scale obtained by using mechanical tests.

    Day 0 + 2 hours

  • Validation of the VISIODOL® scale in screening of pain in people with visual impairment using the correlation coefficient between the intensities measured with the Numerical Scale (NS) and the VISIODOL® scale obtained by using mechanical tests.
