The aim of this study was to examine the type, frequency and usage rate of assistive devices in daily life activities in a community-based population aged 70 and over (N = 170), as well as the particular part of the intervention trial which focused on un-met needs, and the usage rate and effectiveness of assistive devices 6 and 12 months after prescription. Among persons under 80 years of age, 24% were users of assistive devices; in the 80 years or above group, this figure rose to 57%. Hygiene and mobility devices were the most common. The usage rate of assistive devices was 84%. The reasons for disuse were an improved health status, or difficulties in using the device. Sixteen percent of the study population had un-met needs of assistive devices. At follow-up visits, the subjects estimated a high degree of effectiveness when using the devices, particularly in the form of reduced difficulty and increment of safety, and increased capacity and ability in various activities. We conclude that the use of assistive devices increases with age, and that most of the assistive devices are used and are effective. As the need for assistive devices changes over time, follow-ups in the home are necessary. Therefore, to meet the needs of a growing elderly population, information about assistive technology should be supplied to both personnel in health care and in the social service system.
