Soterix CAS + HD-tDCS Tinnitus Pilot Study
Also known as: The Effects of Compensatory Auditory Stimulation and Transcranial Direct Current Stimulation on Tinnitus Perception, The Effects of Compensatory Auditory Stimulation and High-Definition Transcranial Direct Current Stimulation (HD-tDCS) on Tinnitus Perception - A Randomized Pilot Study, Compensatory auditory stimulation, CAS, High-definition transcranial direct current stimulation, HD-tDCS, Combined CAS and tDCS, CAS + tDCS, NCT02648542
Soterix Medical
Published randomized pilot study testing customized compensatory auditory stimulation, high-definition transcranial direct current stimulation, their combination, and sham stimulation for acute tinnitus-perception changes. The tDCS hardware/software was supplied by Soterix Medical, but the CAS and CAS+tDCS arms are protocol conditions rather than separate commercial products.
Verified as a completed Soterix-sponsored pilot study, not as a marketed tinnitus product. ClinicalTrials.gov and the publication describe one randomized crossover pilot with CAS, HD-tDCS, combined CAS+HD-tDCS, and sham conditions. The protocol arms should remain collapsed into this study-level record.
