Effects of a Nanotechnology-Based Application on Balance Control in Hearing Aid Users

Area of Science:

• Gerontology
• Biomedical Engineering
• Audiology

Background:

• Age-related hearing loss is linked to postural instability and falls in older adults.
• Multisensory integration deficits contribute to balance impairment.
• Limited interventions exist for auditory input and postural control interaction.

Purpose of the Study:

• To investigate the effect of Taopatch® nanotechnology integrated into hearing aids on postural control in individuals with hearing loss.
• To assess if localized photobiomodulation can enhance balance in older adults.

Main Methods:

• Forty hearing aid users (mean age 77.3) underwent five postural assessments using a baropodometric platform.
• A double-blind, placebo-controlled design was used, comparing Taopatch® to a placebo patch.
• Static and stabilometric parameters were analyzed under open- and closed-eye conditions.

Main Results:

• The Taopatch®-integrated device significantly reduced sway path length (-8%) and mean velocity (-8%), indicating improved postural control.
• Low-frequency sway decreased by 30%, suggesting enhanced stability.
• Lateral plantar load redistribution and increased contact surface area (+15%) were observed, particularly with eyes open.

Conclusions:

• Localized photobiomodulation via Taopatch® integrated into hearing aids shows potential for improving postural stability in older adults with hearing impairment.
• The findings suggest a positive influence on sensory integration processes.
• Further research is warranted to confirm efficacy and elucidate mechanisms.
