The still increasing life length expectancy creates new challenges in the field of senior care. It encourages researchers to provide the nursing homes and senior care assistants with tools that will both, rise an alarm in case of a sudden fall and collect data for long-term diagnosis of the declining motor abilities like the number of steps taken per day or changes in some gait parameters. This paper presents a quantitative validation of a remote system for activity monitoring of the elderly based on inertial sensors. It focuses on features connected to walk quality such as number of steps and the swing angle outlined by an ankle in the sagittal plane during walk. A measurement protocol is proposed, a validation method is described and the obtained results are discussed.
