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.
目的
通过测量传感单元中的力和时间来评估T-Scan®III传感器系统的有效性和可靠性。
方法
为评估有效性，将已知力施加于从T-Scan®III传感器中随机选择的31个传感单元上。为评估可靠性，测量两个不同传感器之间的现有一致性。使用林氏一致性相关系数（CCC）评估有效性和可靠性。
结果
使用麦克布赖德量表，对于传感单元的整个组，通过测量力，获得了较差的有效性水平（林氏CCC：0.698）；测量时间时，获得了几乎完美的一致性（林氏CCC：0.9995）。相比之下，可靠性水平较差（林氏CCC：0.099）。
讨论
T-Scan®III系统在估计绝对力时既未显示出适当程度的有效性，在测量相对力时也未呈现出足够的可靠性水平；然而，在量化时间时它呈现出高度的有效性。
