The Effects of Age and Hearing Loss on Dual-Task Balance and Listening.

ABSTRACT:

Objectives

Among older adults (OA), hearing loss is associated with an increased risk for falls. The aim of the present study was to experimentally investigate the cognitive compensation hypothesis, wherein decreased auditory and motor functioning are compensated by the recruitment of cognitive resources.

Method

Twenty-nine younger adults (YA), 26 OA, and 32 OA with age-related hearing loss (ARHL) completed a dual-task paradigm consisting of cognitive and balance recovery tasks performed singly and concurrently. The auditory stimuli were presented with or without background noise.

Results

Both older adult groups performed significantly worse than YA on the cognitive task in noisy conditions and ARHL also demonstrated disproportionate negative effects of dual-tasking and noise. The kinematic data indicated that OA and ARHL demonstrated greater plantarflexion when compared with YA. Conversely, YA showed greater hip extension in response to dual-tasking.

Discussion

The cognitive and balance results suggest that YA were able to flexibly allocate their attention between tasks, whereas ARHL exhibited prioritization of posture over cognitive performance.

Project description:Objectives The aim of this study was to evaluate listening self-efficacy ratings between aided and unaided conditions in different communication environments and to determine what patient- and device-centered variables were associated with individual differences. Method An observational, cross-sectional study design was used to evaluate 165 older adults with mild to moderately severe sensorineural hearing loss who wore hearing aids at least 8 hr per week. Listening self-efficacy for both unaided and aided listening was measured using the Listening Self-Efficacy Questionnaire (LSEQ; Smith, Pichora-Fuller, Watts, & La More, 2011), consisting of a global score and subscales of Dialogue in Quiet, Directed Listening, and Complex Listening. Metrics to explain variability in the degree of improvement in LSEQ ratings with aided listening included patient-centered variables of age, pure-tone average, and personality and device-centered variables of hearing aid use, speech intelligibility index, directionality, and noise reduction. The NEO Five-Factor Inventory (Costa & McCrae, 1985) was used to measure 5 personality traits (neuroticism, extraversion, openness, agreeableness, and conscientiousness). Associations were evaluated between LSEQ ratings and patient- and device-centered variables using a linear mixed-model analysis. Results Statistically significant improvements in LSEQ ratings were found for aided conditions (relative to unaided conditions), easier listening environments, lower pure-tone averages, and lower levels of neuroticism. Furthermore, the improvement in listening self-efficacy with hearing aids did not depend on the listening environment but did alter with severity of hearing loss, length of hearing aid use, and levels of conscientiousness. Conclusions Results of this study suggest that wearing hearing aids is associated with improved listening self-efficacy in a variety of communication environments. Aural rehabilitation and counseling may focus on improving listening self-efficacy to address the challenges of consistent hearing aid use and reduced quality of life related to hearing loss.

Project description:BackgroundHearing loss (HL) can affect communication in complex ways. Understanding how adults with HL reflect on and conceptualise the way they listen (metacognition) is required if interventions, and the outcome measures used to evaluate them, are to address barriers to functional communication arising from HL.ObjectivesThis study describes how adults with HL experience and report the processes, behaviours, and components of listening, as presented in published studies.DesignSystematic review and meta-synthesis of qualitative studies.MethodsSystematic searches identified English-language, peer-reviewed journal articles reporting the results of qualitative or mixed-methods studies of adults' with HL perceived listening abilities. Medline, PsychInfo, Web of Science, Embase, and Google Scholar were searched from inception to November 2021. Handsearching reference lists of included studies identified additional studies for inclusion. The Critical Appraisal Skills Programme (CASP) qualitative checklist was used to appraise studies' methodological quality. Data from included studies were analysed using thematic meta-synthesis. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) Confidence in the Evidence from Reviews of QUALitative (CERQual) approach assessed confidence in the review findings. Two reviewers independently completed all screening and quality appraisal. Thematic meta-synthesis and GRADE CERQual assessment was completed by one reviewer and confirmed by a second reviewer. Discrepancies were resolved through discussion.ResultsData from 46 studies were included in the review. Thematic meta-synthesis identified six descriptive themes: 1) perceived listening ability; 2) external modifiers; 3) psychosocial impacts of hearing loss; 4) communication partner perspectives; 5) self-efficacy for listening; and 6) cognitive load. GRADE CERQual ratings for descriptive themes ranged from low to moderate confidence. Descriptive themes were related by analytic themes of liminality and reciprocity.ConclusionsAdults with HL provide in-depth accounts of components and processes of listening, with studies reporting both cognitive and affective experiences consistent with theoretical models of metacognition. The findings will inform content generation for a hearing-specific patient-reported outcome measure of perceived listening ability in everyday communication.

Project description:Age-related hearing loss has been associated with increased recruitment of frontal brain areas during speech perception to compensate for the decline in auditory input. This additional recruitment may bind resources otherwise needed for understanding speech. However, it is unknown how increased demands on listening interact with increasing cognitive demands when processing speech in age-related hearing loss. The current study used a full-sentence working memory task manipulating demands on working memory and listening and studied untreated mild to moderate hard of hearing (n = 20) and normal-hearing age-matched participants (n = 19) with functional MRI. On the behavioral level, we found a significant interaction of memory load and listening condition; this was, however, similar for both groups. Under low, but not high memory load, listening condition significantly influenced task performance. Similarly, under easy but not difficult listening conditions, memory load had a significant effect on task performance. On the neural level, as measured by the BOLD response, we found increased responses under high compared to low memory load conditions in the left supramarginal gyrus, left middle frontal gyrus, and left supplementary motor cortex regardless of hearing ability. Furthermore, we found increased responses in the bilateral superior temporal gyri under easy compared to difficult listening conditions. We found no group differences nor interactions of group with memory load or listening condition. This suggests that memory load and listening condition interacted on a behavioral level, however, only the increased memory load was reflected in increased BOLD responses in frontal and parietal brain regions. Hence, when evaluating listening abilities in elderly participants, memory load should be considered as it might interfere with the assessed performance. We could not find any further evidence that BOLD responses for the different memory and listening conditions are affected by mild to moderate age-related hearing loss.
