Correlation between the handicap and the benefit of hearing aid use in adults and elderly

CONCLUSION: Adult and elderly subjects showed a reduction of handicap in daily activities with the use of hearing aids. The bigger the benefit obtained in the subscale Ease of Communication for the elderly and in the subscale Background Noise for the adults, the greater the handicap reduction.

Assessment of the swallowing function in older individuals referred to myocardial revascularization surgery

CONCLUSION: older individuals with heart disease presented differences in the swallowing function when compared to healthy older individuals. Older individuals with heart disease presented alterations in the temporal coordination between breathing and swallowing, thus indicating risk for dysphagia.

Auditory temporal resolution in elderly people

CONCLUSION: The presence of hearing loss increased the gap detection thresholds and lowered the percentage of correct responses on the Gaps-in-Noise test.

Auditory temporal resolution threshold in elderly individuals*

CONCLUSION: the average temporal resolution threshold for women was 104.81ms. Considering gender, females did not present correlations between age and audiometric configuration, not only when considering the RGDT results but also when analyzing the SAC results.

Description of the feeding dynamics of institutionalized elderly women

CONCLUSION: Environmental, cognitive and behavioral factors related to feeding were significantly present among the subjects of the study, putting deglutition at risk. Other specific deglutition difficulties were also identified. Managing these difficulties is important, in order to avoid health complications for elderly women

An exploratory study of auditory extinction in ageing: Now you hear it, now you don’t

Outcomes & Results: Participants in all groups made significant omission errors in both binding and non-binding conditions, demonstrating extinction in healthy individuals. Additionally, older participants required increased stimulus delays to decrease percentage of omission errors.

Conclusions: These results suggested that auditory extinction within healthy individuals should be studied further to determine the extent of the influence of normal extinction performance for individuals following stroke.

Aging, voice and physical activity of teachers and non-teachers

from Revista da Sociedade Brasileira de Fonoaudiologia

PURPOSE: To compare the voices of elderly subjects, teachers and non-teachers, and to verify the relationship between their voices and the variables chronological age and period of time practicing physical activity.
METHODS: It was carried out the perceptive-auditory analysis of the vocal parameters of 47 subjects, male and female, who were older than 65 years. Twenty three subjects were teachers (GT) and 24 were non-teachers (GNT). The results of this analysis were tested for statistical correlation with the variables chronological age and amount of physical activity practice (in time).
RESULTS: In the GT, there was a significant negative correlation between chronological age and loudness variation (p=0,042). In the GNT it was found significant negative correlations between chronological age and speech rate (p=0,038) and between period of physical activity practice and voice quality deviations (p=0,031).
CONCLUSIONS: There were no statistical differences among the vocal parameters of both groups. For the GP, it was observed that the higher the chronological age, the lesser the loudness variation. For the GNP, the higher the chronological age, the lesser the speech rate. A longer period of physical activity practice was correlated to a voice with lesser quality deviations, only for the GNP.

Performance of elderly in a speech in noise test

from Pró-Fono Revista de Atualização Científica

BACKGROUND: speech perception of elderly, in silence and in the presence of background noise.
AIM: to characterize and compare the hearing abilities of elderly in a monaural speech perception test, in the presence and absence of background noise (Speech Discrimination Test – SDT and Speech Perception in Noise – SPIN).
METHOD: Participants of this study were 55 subjects of both genders, 60 years old or above, distributed in two groups: Control Group (CG), constituted by elders with no hearing loss and Study Group (SG), constituted by elders with symmetrical sensorineural hearing loss. The SPIN test was used, initially with the presentation of a word list in silence and later in the presence of Speech Noise.
RESULTS: no difference was observed between genders in the SDT and the SPIN test. Correlation with age was observed only in the SDT for SG. A significant difference was observed when comparing the performance of the groups in the SDT and SPIN test. Regarding the presence of substitutions in the articulation of words, it was observed that it occurred in both groups and was more frequent in SPIN test, especially for the SG.
CONCLUSION: the presence of the noise during the production of speech sounds is disadvantageous for elders, independently of the presence of hearing loss, but having a higher impact for those with hearing loss problems.

Geriatric patients receive significant benefit from cochlear implantation


Despite previous inconclusive research, geriatric patients do experience significant quality of life improvement (QOL) after receiving cochlear implants for hearing loss, says new research presented at the 2008 American Academy of Otolaryngology – Head and Neck Surgery Foundation (AAO-HNSF) Annual Meeting & OTO EXPO in Chicago, IL.

Cost-Effectiveness of Hearing Aids in the Hearing-Impaired Elderly: A Probabilistic Approach

from Otology & Neurotology

Objective: Hearing aids are the principal tool for rehabilitation of hearing loss, one of the most prevalent impairments among elderly adults, but cost-utility ratings for hearing aid use are limited.

Design: Cost-effectiveness analysis.

Setting and Patients: A multistate Markov model was constructed to model 50- to 80-year-old patients moving between states, including normal hearing, mild, moderate, or severe hearing loss. Parameters assigned in the model are partly derived from the Medline source (1966-2005) and partly from data on hearing-impaired elders (n = 96) in a tertiary care center in Taiwan. To address uncertainty, most of the parameters were specified by distributions, rather than base-case values. A probabilistic approach with Monte Carlo simulations was performed to produce an acceptability curve, showing the probabilities of being cost-effective given threshold values of willingness to pay (WTP).

Main Outcome Measures: Hearing-related quality-adjusted life-years and cost in US dollars and Euros.

Results: The incremental costs for gaining an additional hearing-related quality-adjusted life-years in women and men were US $13,615 (Euro 10,826) and 9,702 (Euro 7,715), respectively. The probability of being cost-effective increased to 53% in women and 65% in men given a WTP of US $12,000 (Euro 9,542). The probabilities of being cost-effective to reach plateau were 67% for women and 78% for men given a WTP of US $20,000 (Euro 15,904).

Conclusion: By modeling different degrees of hearing loss with a multistate model, hearing aid use was demonstrated to be a cost-effective strategy to rehabilitate the hearing-impaired elderly. These results can assist policy makers in allocating health resources appropriately and effectively.
