Abstract
Frailty is an intermediate state in the ageing
trajectory, preceding the onset of disability. It can be assessed
via clinical, cognitive, nutritional, and physical performance
components, whereas one component of physical assessment is
measurement of lower limb strength. We propose a device for
measuring lower limb strength based on the 30s sit-to-stand test
(30s-STS) in an autonomous environment. The device is based
on an ultrasound sensor that is mounted on the backrest of a
chair and measures the distance to the back of the patient. A
signal processing algorithm was developed with a dataset of
healthy subjects and evaluated prospectively with geriatric
patients. Results of evaluation show that measurement for
geriatric patients is poorer than expected. Thus, we plan to retrain
the algorithm with additional geriatric patients, and to
study further the complexities of the 30s-STS analysing aspects
such as the inter-observer-variability of reference annotations.
The new algorithm will be evaluated as part of a clinical trial
with 40 elderly patients at their dwelling. The clinical trial will
also assess the acceptability of such a device in a home setting.
