Clinical Testing on the Internet of Things Automatic Chair for Fall Risks

Overview

Muscle weakness is the most significant indicator of age-related loss of function and is associated with poor mobility and mortality. Limitations in the person's ability to stand reflect muscle weakness, poor balance, and risk of falls. The 30-Second Chair Stand Test and 5-Time Sit-to-Stand Test are standardized tests that evaluate muscle weakness and fall risks. An Internet of Things (IoT) Chair was developed by Lee et al. automatically timed and counted the number of sit and stand cycles a person can do in 30 seconds, which is the 30-second Chair Stand Test. The chair also recorded how fast a person could do five sit-and-stand cycles, which is the 5-Time Sit-to-Stand Test. The IoT Chair developed by Lee et al. was not validated in a clinical setting. This project tested the accuracy of the IoT Chair in a clinical trial. IRB approval was obtained from Azusa Pacific University. One hundred and two patients were recruited for the study. The participants were simultaneously tested on both the 30-second Chair Stand Test and the 5-time Sit-to-Stand Test. The IoT Chair was found to have similar results compared to the currently used observer method. Since the IoT produced reliable results, this supports using the IoT Chair in doctors' offices. This IoT Chair can help physicians detect patients' leg weakness and fall risks. Early leg weakness detection can help prevent falls, prolong patient lives, and decrease healthcare costs.
