Automatic fall detectors and the fear of falling.

We studied the effect of automatic fall detection units on the fear of falling. Participants were community alarm users living in the community aged over 75 years or those aged 60-74 years who had experienced a fall in the previous six months. Of those approached, 31% consented to take part; the main reason given for potential participants declining involvement was that they were happy with the technology they already had. Subjects were assigned to a control group (n = 21) or intervention group (n = 34) based on age, the number of self-reported falls in the previous six months and their score on the self-administered Falls Efficacy Scale (FES), which measures fear of falling on a scale of 0-100, with higher scores indicating less fear. The monitoring period lasted a mean of 17 weeks (SD 3.1). There was no significant difference between the intervention and control groups in their mean ratings of fear of falls (40.3 vs 37.5, difference 2.8, 95% CI 6.2 to 11.8), health-related quality of life or morale. Differences in fear of falling between an intervention subgroup who wore their detector at least occasionally (62%) and those who did not (38%) suggested that some people may benefit from a fall detector while others may lose confidence if they are provided with one. Most users who wore their detectors at least occasionally felt more confident and independent and considered that the detector improved their safety.
