Objective:
To evaluate the validity and reliability of the T-Scan®III sensors system by measuring force and time in sensels.
Methods:
In order to evaluate the validity, known forces were applied to 31 sensels selected at random of a T-Scan® III sensor. In order to evaluate the reliability, the existing agreement between two different sensors was measured. Both validity and reliability were assessed using Lin's concordance correlation coefficient (CCC).
Results:
Using the McBride's scale, for the total group of sensels, by measuring force, a poor level of validity was obtained (Lin's CCC:0.698); when measuring time, an almost perfect agreement was obtained (Lin's CCC: 0.9995). In contrast, the reliability level was poor (Lin's CCC: 0.099).
Discussion:
The T-Scan®III system neither shows an appropriate degree of validity when estimating absolute force, nor presents an adequate level of reliability when measuring relative force; however, it presents a high degree of validity when quantifying times.
