  This study aimed to investigate the human ability in discrimination of spatial and temporal parameters in electrocutaneous stimulation. Three surface electrodes were positioned on the ventral forearm of 14 able-bodied subjects. The subjects were instructed to discriminate between: (1) six different stimulation sites or site pairs, or (2) five different stimulation frequencies, or (3) hybrid parameters including both stimulation site and frequency, in three respective experiments. The results showed that two-site discrimination had a significantly lower success rate than one-site discrimination with a mean difference up to 12.1% (p<0.01). Temporal (frequency) discrimination appeared more challenging compared to spatial (site) discrimination. Moreover, the female subjects’ performance was noticeably better than the males in all the three discrimination tasks with the mean diffe.. View More»
