One of the most intriguing aspects of recent declines in old age disability is the concurrent increases in use of assistive devices among older persons with disability, and in particularly in use of devices for all disabilities without human assistance. This study updates information on trends in assistive device use and characteristics of device users; examines differences in the hours of care received by persons who do not use devices and those who use devices with and without help; and discusses implications for multivariate modeling of the relationship between device use and hours of help and other outcomes. Data are from the 1984 through 1999 rounds of the National Long Term Care Survey (NLTCS), which has been the key source of earlier information on trends in equipment use.
