Strength-Duration Time Constant in Peripheral Nerve: No Abnormality in Multiple Sclerosis
Figure 1
(a) The relationship between stimulus strength (mA) and stimulus duration (ms) in patient 11. (b) The relationship between stimulus duration and the stimulus charge in the same patient. The SDTC is given by the intercept of the linear regression line on the duration axis and was calculated as follows: when y is accepted as zero, x is obtained by dividing 4.1414 by 1.6941, as an example.
