Poster #65: Abby Citterman – Low Frequencies Improve Intensity Discrimination for Low-Cost, Non-Invasive Electrocutaneous Stimulation

Faculty mentor: Jacob George

Electrocutaneous stimulation uses electrodes on the skin to evoke tactile sensation and is used to provide amputees with more natural and intuitive somatosensory feedback. We measured the just-noticeable difference (the minimum change in stim frequency that can be identified correctly 75% of the time) to describe how well electrocutaneous stim conveys the magnitude of tactile stimuli, an essential characteristic of natural touch. We found that low frequencies improve intensity discrimination.
