Postural Modification and Hearing Aids in Presbycusis

Study Overview
=================
Brief Summary
-----------------
Presbycusis could be associated to increased risk to fall. There is little about the impact on postural balance of hearing aids. In this study, the investigators describe the postural balance evolution before and after hearing aid fitting in presbycusis-affected adults (55-80years old) consulting Angers University Hospital ENT department and ENT Medical Doctor of Le Mans .

Detailed Description
-----------------
After being informed about te study and consentment, patients meeting inclusion criteria consulting for presbycusis and in indication for hearing aids will be included to have posturometry (V0). Posturometry is performed 3 months later, before the first hearing aid installation (V1a) and after (V1b), as well as three months after hearing aid wearing (V2). Evolution of posturometry parameters without hearing aids between V0 and V1a serve as control and is compared to the evolution of posturometry parameters after hearing aid wearing between V1b and V2.

Design Details

Primary Purpose: Other
Intervention Model: Single Group Assignment
Interventional Model Description: Prospective study, with analysis of posturography parameters variation before and after hearing aid fitting in age-related hearing loss affected population aged 55 to 80 years old.
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Other: age-related hearing loss affected before hearing aid fitting<br>patients aged 55 to 80 years old, undergoing posturography at diagnosis of ARHL and 3 months later before hearing aid fitting, within the role of control same patients udergoing posturography at hearing aid fitting and 3 months after. | Other: posturography<br>* posturography will be performed when diagnosis of ARHL, in need of hearing aid fitting, is done and after information and written approval from patient. Posturography is performed later when hearing aid fitting and 3months after hearing aid use<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Elliptic surface variation in posturography assessment before and after hearing aid fitting in presbycusis patients | analysis of variation of elliptic surface (cm2), eyes opened and closed, and subsequent romberg quotient (elliptic surface closed eyes/elliptic surface opened eyes) in the 3 months before hearing aid fitting and the 3 months after | 3 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| the effective wearing time of the device since its installation | average of time within hearing aid use per day (on the last 3 months) | 3 months | 
| the severity of the initial hearing loss | calculation of the average hearing loss measured by the average of the hearing thresholds without a hearing aid at 0.5, 1, 2 and 4 kHz | 3 months | 
| the notion of a balance disorder described by the patient | vertigo or feeling of instability | 3 months |
