About this study
This study will investigate the balance performance and balance-related activities of daily living in 35 industrial workers with hearing problems exposed to occupational noise, using the Berg Balance Scale and the Vestibular Disorders Activities of Daily Living Scale. The research aims to determine whether there is a statistically significant association between hearing problems, balance performance, and daily noise exposure duration. It is hypothesized that while hearing problems related to occupational noise exposure may exist, they may not be directly associated with clinically significant balance impairment, potentially remaining at a tolerable level in daily life. Furthermore, the correlation between Berg Balance Scale and daily living activity scores will be evaluated to understand the functional impact of balance on these workers.
Read the detailed description
Background:
Industrial workers are frequently exposed to high levels of occupational noise, which constitutes one of the most common causes of hearing problems and noise-induced hearing loss. In addition to auditory impairment, prolonged noise exposure may affect balance functions due to the close anatomical relationship between the auditory and vestibular systems.
Objective:
The aim of this study is to investigate balance performance and balance-related activities of daily living in industrial workers with hearing problems who are exposed to occupational noise.
Methods:
This cross-sectional study will include 35 industrial workers with hearing problems who are exposed to occupational noise. Balance performance will be assessed using the Berg Balance Scale, and balance-related activities of daily living will be evaluated using the Vestibular Disorders Activities of Daily Living Scale. Sociodemographic characteristics and duration of daily noise exposure will be recorded. Statistical analyses will be performed using non-parametric tests and correlation analysis to identify potential relationships between variables.
Expected Outcome / Conclusion:
The study intends to determine whether balance problems experienced by industrial workers with hearing problems remain at a tolerable level in daily life. It is hypothesized that hearing problems related to occupational noise exposure may not be directly associated with clinically significant balance impairment in this population.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| industrial workers | * Employment in industrial or heavy industrial settings * Age between 18 and 60 years * Presence of hearing problems diagnosed prior to or after starting industrial work |
What is being measured
The primary outcome is the main question the study is designed to answer.
Berg Balance Scale
The Berg Balance Scale was used to assess static and dynamic balance performance. The scale consists of 14 items and scores range from 0 to 56, with higher scores indicating better balance performance.
Measured: Day 1
Vestibular Disorders Activities of Daily Living Scale
The Vestibular Disorders Activities of Daily Living Scale (VADL) was used to evaluate balance-related difficulties in daily life. he scale assesses functional, ambulation, and instrumental activities of daily living across 28 items. Scores range from 1 to 10, where higher scores indicate a worse outcome (greater self-perceived disability).
Measured: Day 1
