ABSTRACT

The purpose of this study was to investigate the effects of auditory rehabilitation program for cochlear implanted children during off-switch state. The effect was measured with mapping data. The mapping data were analyzed in terms of threshold level, comfortable level, and dynamic range. Eight subjects participated in the study. The subjects were free from intellectual, emotional, behavioral or visual problems. The 8 subjects in the experiment were assigned into one of the 2 groups: 4 in the experimental group and the remaining 4 in the control group. The experimental group was subjected to the multisensory auditory rehabilitation program. The Off-Switch program was composed of 3 activities: visual feedback, tactile feedback, and body movements. RION HU-05 AUDIO SPECTORA and VST 2002 were used as the visual feedback devices. RION AU 02B Vibratory Sensation Meter was used as the tactile feedback device. Body movement activities were developed by the author based on the Verbotonal method(Asp, 2000). The intervention took place twice a week. Each session lasted 40 minutes. A t-test was performed between the 2 groups on threshold level, comfortable level, and the dynamic range. The results were as follows: the comfortable level of experimental group was significantly higher and the dynamic range of experimental group was significantly wider. The implication of the study is that the multisensory auditory rehabilitation program was effective in making the mapping process more stable.
