The aim of the study was to investigate the “Effect of the fall prevention intervention program OTAGO on older persons with frailty and prefrailty—an analysis with conventional geriatric and technology–based assessments”. The observational randomised pilot intervention study was conducted from 07/2014 to 06/2015. Data of 20 participants (17 female, 3 male) was collected during 36.5 weeks on average. Two participants passed away during the study. Considering the pilot study character and technology focused approach, the number of participants was sufficient. The inclusion criteria for the study were Age At least pre–frail by the definition of FriedLiving alone within the city limits of OldenburgAble to move inside the flat as neededNot able to move inside the flat as neededKeeping pets that move freely inside the flatLiving with other peopleStrong visual impairmentContraindication against the OTAGO exercise programmeUnable to understand the purpose of the study and the study itselfThe sensor system, which was installed in the homes of the participants, was comprised of home automation, power consumption, and two wearable sensors—one IMU and one GPS receiver. The power consumption sensors were installed between appliances and outlets, measuring the electricity consumption of the connected device. In terms of home automation sensors, passive infrared (PIR) motion sensors and door contact sensors were installed in each apartment. The door contact sensors were installed at the front door, windows, fridge, and the backdoor, if applicable. Additionally, a concussion sensor was placed in-between the slatted frame and the mattress. An extra four-key switch was placed near the front door and the participants were asked to turn the switch when another person enters or leaves the flat. All sensors send transmitted their data to a base station using a wireless connection.
