Study Modules > Module V: Sensory: Hearing and Touch/Dexterity

Hearing and touch (which includes dexterity) also changes as we age. They, too, do not change at the same time in our lives. These senses change gradually but will affect our functional activities over time. Dexterity involves the ability to use the fine motor muscles in our hands to grip, pinch, twist, turn or rotate. In this module, we cover from commonly used assistive devices to newer devices on the market. The devices illustrated in this module are used to serve as examples only for the type of devices that are available to help the caregiver and care recipient with hearing and dexterity. It is not our intent to recommend these devices over other devices available on the market. This module includes photos that show the devices.

Selection criteria of assistive devices in this module are in the order of: 1. suitability for various levels of physical and cognitive impairments, 2. ability to ease physical stress for the caregivers, 3. easy availability, 4. great usability and convenient storage, 5. esthetic, 6. variety of prices, and 7. novelty to the market.

As found with our other sensory areas, we also undergo changes to our hearing and touch as we age. Studies have indicated that these sensory changes accelerate at certain approximate age ranges: [ 1 ]

• Hearing – mid 40s
• Touch – mid 50s
