Can We Rely on Mobile Devices and Other Gadgets to Assess the Postural Balance of Healthy Individuals? A Systematic Review

Abstract: The consequences of falls, costs, and complexity of conventional evaluation protocols have motivated researchers to develop more effective balance assessments tools. Healthcare practitioners are incorporating the use of mobile phones and other gadgets (smartphones and tablets) to enhance accessibility in balance evaluations with reasonable sensitivity and good cost–benefit. The prospects are evident, as well as the need to identify weakness and highlight the strengths of the different approaches. In order to v… Show more

“…The first stage was to identify systematic reviews that investigated ‘postural balance’, ‘inertial sensors’, and ‘reproducibility of results’ via the reference list of a scoping review of systematic reviews previously conducted [ 16 ]. This search identified five systematic reviews [ 3 , 12 , 14 , 17 , 18 ]. One further relevant systematic review [ 7 ] was published after the scoping review went to press.…”

“…Several devices with embedded IMU have been investigated for their concurrent validity for measuring postural stability [9]. Several studies have compared postural stability measures between force plates and IMUs from smartphones [10,11] (systematically reviewed in [9,12]). While most of them found a significant relationship between the outcomes of the smartphone and the force plates, these were often very variable from one condition to another.…”

“…Furthermore, the small sample sizes used in previous studies prevent one to assess the strength of this relationship reliably [13] as underpowered studies tend to overestimate the size of the correlations [14]. Furthermore, several of the previous studies [9,12] did not take age as a covariate, which tends to artificially increase the reported correlation coefficients. Therefore, the primary aim of our study is to estimate the strength of the relationship between smartphone embedded IMU and force plate measures of postural stability in a large group (~100) older adults across four conditions (eyes open, eyes closed, dual-task and semi tandem condition).…”

“…The trunk is considered the optimal place for the location of the sensors because, in this position, the sensor is the closest to the COM. 41 There are some doubts as to the position of sensors on the head because although the vestibular system is located in this region, the accuracy of the sensors was lower than for the trunk. 40 However, in older people, the head-based model was better at classifying fallers, and multi-sensor models were better at classifying non-fallers.…”
