Pitch-discriminability map comparisons were tested in a blinded crossover RCT design

Evidence

A crossover single-blinded (participant unaware of mapping interventions) randomised control trial was conducted. Prior to starting each participant had their clinical map optimised by adjusting individual channel levels and they received a minimum of 1 month acclimatisation to this optimised map. The crossover study used an A-B-B-A/B-A-A-B design in which map A had indiscriminable electrodes deactivated and map B had an equal amount of discriminable electrodes deactivated. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2075
