To begin, set up the test area and software for iTUG test. Attach reflective markers to the participant's seven cervical spinous processes, ten thoracic spinous processes, the left acromion, and the right acromion. Right click the reflective markers on the right line of the screen to name them as C7, T10, left_shoulder, and right_shoulder.
Present the iTUG test instructions to the participants. Ask the participants to rise from the chair, walk three meters at their preferred speed, turn around, return, and sit. While the participant is performing the iTUG test, click on the start and pause buttons on the screen of the computer.
Next, enter the participant's name in the system for data collection purposes, and press the record button to start the data recording. After recording, review the video to identify the iTUG's test sub-phases. Similarly define the phase two time, phase two body sway, phase three time, phase three body sway, angular velocity of phase three, phase four time, phase four body sway, and phase five time.
Finally, evaluate the falling risk of the participant by using the Downton fall risk index. For this study, 13 aged participants with a high risk of falling and 11 participants with a low risk of falling were studied. Despite no significant differences in sex, age, or overall TUG test scores between the groups, high-risk individuals had notably longer durations in specific iTUG test phases, and lower angular velocity during turning, suggesting impaired mobility.
A significant correlation was found between DFRI scores and the duration of several iTUG test phases, but not with body sway metrics, indicating specific mobility challenges correlated with fall risk.
