In those who only had changes in middle ear impedance without a serotympanon, the decrease in EOAE amplitude was more related to the magnitude of conductive hearing loss than to the change in impedance itself. These results are compared with those of a neonatal screening project in which some of the 532 healthy fullterm newborns showed poor emissions in the first days of life.

During freezing periods the patient produced a sustained /a/ instead of the required consonant-vowel sequences. The underlying articulatory trajectories were characterized by repetition rates amounting to 8-10 Hz concomitant with reduced movement amplitudes. Obviously, the undershooting of articulatory gestures failed to establish a sufficient occlusion of the vocal tract giving rise to the perceived speech freezing. In contrast, preserved diadochokinesis occurred at frequencies of 4-6 Hz. Most probably, the increased articulatory repetition rate reflects a pacing of orofacial movements by released tremor oscillations. Due to slowing of articulatory movements spastic dysarthrics can also present with missing syllabic modulation during oral diadochokinesis.
