Low vision, ADL and hearing assistive device use among older persons with visual impairments

Abstract

Assistive devices (AD) have long played an important role in occupational therapy practice as a way of enabling activities of daily living (ADL), but no studies to date have investigated the use of low vision AD among older persons with age-related macular degeneration (AMD) as well as devices for ADL performance and hearing. The purpose of this study was to describe AD users and to investigate the association of AD and ADL. A health promotion program versus an individual program was investigated within a randomised design. The study was based on data from 131 participants, 28-months after intervention. Data on prescribed ADs were examined through medical records and registers. The participants in the health promotion program used low vision AD in combination with ADL devices to a higher degree, whereas participants in the individual program used just optical AD. Greater use of non-optical AD within the individual program and greater use of ADL devices within the health promotion program was weakly associated with higher level of ADL dependence. There was no significant association between the number of low vision AD and having a decreased, a maintained or improved level of dependence at 28 months.
