Figure 2

Vibration detection threshold (VDT) at 10 Hz and 125 Hz, mechanical detection threshold (MDT), and tactile acuity (TA) in the congenitally deaf cohort (n = 36). Each point represents the threshold for a single subject. All values are normalized for gender on a Z-scale. Dotted lines designate the upper (z = 1.96) and lower (z = −1.96) boundaries of the 95% confidence interval of the normal standard distribution of healthy subjects (n = 111). Z-scores > 0 indicate increased sensitivity. Z-scores < 0 indicate decreased sensitivity to sinusoidal vibrations. *P < 0.05, **P < 0.01, ***P < 0.001, unpaired T-test. Box plots characteristics: center lines show the medians; box limits indicate the 25th and 75th percentiles; whiskers extend 1.5 times the interquartile range from the 25th and 75th percentiles.
