Formatted abstract
This study aimed to determine if acoustic stapedial reflex (ASR) results were affected by testing healthy neonates using two different probe positions. A total of 158 healthy neonates were recruited in this stndy. They were assessed using transient evoked otoacoustic emissions (TEOAEs), high frequency tympanometry (HFT) and ASR tests. Only one ear that was most easily accessible was tested. Ipsilateral ASR testing was performed using a Madsen Otoflex diagnostic immittance meter, with ASRs elicited using a 2 kHz pure tone and broadband noise (BEN) stimuli. ASR thresholds (ASRTs) were recorded for each stimulus in two probe positions: (a) vertical, with the neonate lying with the test ear facing up; and (b) horizontal, with the neonate lying with the test ear facing sideways. The ASRT results, analysed using an analysis of variance (ANOV A), showed no significant effects for the two probe positions irrespective of the type of stimuli (p > .05). These findings imply that the ASRTs obtained from neonates are independent of the probe positions. Hence, normative data obtained using either probe position are clinically valid measures.
