A smartphone-based fall risk assessment tool: Measuring One Leg Standing, Sit to Stand and Falls Efficacy Scale

Abstract: Falls are not an inevitable consequence of ageing. Several fall risk factors can be identified and effective fall prevention techniques applied, which offer an opportunity to reduce falls among older persons. In this paper, the smartphone is proposed as an alternative to traditional methods in the assessment of fall risk factors, including decline in balance, reduced lower limb strength and fear of falling. As such, clinical fall risk assessment tests were adapted to the smartphone in order to measure One Leg … Show more

“…Two previous studies developed a wearable sensor-based version of the OLS test for assessing balance deficits and risk of falling. In one study, the test was instrumented by using sensorized insoles for the estimation of CoP parameters ( 37 ), while in a second study a trunk-worn smartphone was used to estimate trunk displacements during task execution without considering the APA phase and balance phase separately ( 38 ). In addition, the present work is the first effort to adopt an instrumented version of the OLS test to discriminate subjects with idiopathic PD, with and without FOG, and FGD.…”

“…Some traditional standard balance tests, such as sit to stand (STS), uses trunk tilt to evaluate the risk of a fall. The trunk tilt is calculated based on the angles between the sensor and the horizontal line of the ground [31]. the depression on the vertical axis acceleration signal, and the positive and negative angular rotations of the horizontal axis.…”

“…An iPhone 4S smartphone is adopted in the experiments, equipped with STMicro STM33DH 3-axis accelerometer and STIMicro AGDI 3-axis gyroscope. Since the body center of pressure (COP) reveals several information of user gait, the smartphone is placed on the lower back of the trunk, near the real center of mass (COM) position, assuming that this position moves parallel to the COP, and the same accelerations and positions will be measured [ 25 ]. Moreover, three-component acceleration vector describes human movement more precisely [ 50 ].…”

“…In this study, common sensors, such as accelerometers (for measuring the acceleration) and gyroscopes (for measuring the angular rate around one or more axes of the space) are considered since they are easily accessible and do not disturb the privacy of the user (e.g., camera and sound sensors). The popularity of smartphones, the preciseness of the features extracted from embedded sensors [ 23 25 ], and their ability to easily engage to the IoT framework, motivates researchers to exploit smartphones in their studies. Although some studies employ additional sensors [ 18 , 19 ], they bring inconvenience to the users such as wearing augmented shoes, belts, and so on.…”
