Outline of Final Research Achievements

The purposes of this study were to develop an index of measuring independence objectively in ADL of elderly by using an optical sensor (OS) and to determine the effect of exercise using OS. During the course of the study, the OS named KINECT was upgraded to (KINECTv2) by the manufacturer which increased the device’s accuracy. To address the compatibility issue of KINECTv2, we recollected an ADL (chair stand (CS)) data and analyzed the coronal plane angle (CPA) data while performing CS in apparent healthy elderly (HE), and in frail elderly (FE). The CPA exists between a line that connects one’s shoulder-center and waist versus the person’s vertical axis (sagittal plane). The CPA was found to be significantly smaller in HE than in FE while performing CS indicating that OS is effective in assessing independence to complete the CS. However, no exercise intervention efficacy was noted on CS when assessed by the OS, thus further study is needed to address this issue well.
