Manual dexterity and successful hearing aid use

Area of Science:

• Audiology
• Gerontology
• Rehabilitation Science

Background:

• Fine motor skills are crucial for manipulating small devices like hearing aids.
• The relationship between manual dexterity and hearing aid usability in older adults requires further investigation.

Purpose of the Study:

• To assess the correlation between manual dexterity and the perceived benefit of hearing aid use.
• To compare hearing aid success between 'behind the ear' and 'in the ear' device types.

Main Methods:

• 30 participants aged 65-85 using hearing aids were evaluated.
• Manual dexterity was assessed using the Purdue pegboard test.
• Hearing aid benefit was measured via a questionnaire.

Main Results:

• A significant correlation was found between manual dexterity and hearing aid success when analyzing all participants together.
• No significant correlation was observed between manual dexterity and hearing aid success within the 'in the ear' hearing aid subgroup when analyzed separately.

Conclusions:

• Manual dexterity is a factor in the successful use of hearing aids among older adults.
• The type of hearing aid may influence the relationship between manual dexterity and user satisfaction.
