Table 1: Comparison between absolute and interpeak auditory brainstem response latencies in study and control groups Normal Get up & go test all participants were able to perform the test in the range between10-28 seconds. VEMP results showed that P13and N 23 latencies were prolonged in the study group when compared to the control group and this prolongation was highly statistically significant, also amplitude P13-N23was reduced in study group in comparison to the control group and this reduction was highly statistically significant as shown in and. VNG results, all participants showed normal occulomotor test battery, no positional or positioning nystagmus and normal caloric results. Also IPLs were prolonged in study group than control group but this prolongation is not statistically significant as shown in and. ABR results showed that absolute peak latencies of wave I, III & V were prolonged in study group than control group and this prolongation was highly statistically significant. Patients in study group had bilateral speech discrimination scores in the range of (72-84%) with the mean 75.3 and SD 3.2 and type (A) tympanogram indicating normal middle ear pressure and acoustic reflex threshold are preserved at 250Hz,500HZ, 1000Hz but lost at 4000Hz in some cases. All participants in control group had bilateral speech discrimination scores in the range of (88-100%) with Mean 97.7 and SD 3.9 and type (A) tympanogramindicating normal middle ear pressure and acoustic reflex threshold were within normal. Mean PTA value was 20.71dB (min-max 10-25) in the control group and was 35.53 dB (min-max 31-60) in the study group ( P < 0.05). ABR and VEMP results of the groups were calculated and compared.Ībsolute peak latencies of ABR waves I, III, and V were prolonged in the study group than the control group ( P 0.05). Patients were divided into two groups: a study group (patients with SNHL) and a control group (patients without SNHL). ‘Get up and go’ test was used as a quick screening tool for detecting balance problems. The vestibular system was assessed using videonystagmography test battery, sensory organization test, and vestibular evoked myogenic potential (VEMP). Audiological status was measured with auditory brainstem response (ABR). This study comprised 40 adult patients (50–75 years) without any vestibular symptoms or diagnosed vestibular diseases. Once one is stimulated, the other experiences changes as well. So, there is a great relation among their functions. Although auditory and vestibular systems are distinct, they work just alike. A considerably high number of these patients with presbycusis or age-related SNHL also experience dizziness and related vestibular symptoms. Presbycusis or age-related sensorineural hearing loss (SNHL) is a complex disorder that results in a slow deterioration in auditory function.
