Frequency-dependent current perception threshold in healthy Japanese adults.

ABSTRACT

The purpose of the study involves measuring the threshold for electric currents (i.e., current perception threshold or CPT) under several stimulating current frequencies. Specifically, current perception threshold (CPT) was measured in 53 healthy volunteers between the ages of 21 and 67. The stimulation currents were applied on the right index finger with stimulus frequencies in the range of 50 Hz - 300 kHz. The method of limits and method of constant stimuli were combined to measure the CPT. In a manner consistent with the findings obtained by previous studies, the results indicated that CPT was higher in men than in women and in older individuals than in young subjects.
