The study conducted is a prospective cross-sectional study approved by the Institutional Review Board of Chang Gung Medical Foundation with the aim of assessing body segment lengths in healthy Taiwanese women aged 6 to 60 years. The research excluded pregnant women, individuals with chronic diseases, limb defects, and pacemaker implantation. All procedures followed ethical standards and were in accordance with the 1964 Helsinki Declaration. Written informed consent was obtained from all participants or their legal guardians.
Measurements were taken using anthropometric methods such as body height and weight measurements, along with Azure Kinect and DXA technology. The Azure Kinect DK device was utilized for Kinect measurements, capturing joint coordinates for the upper arm, forearm, thigh, and leg segments. The DXA system from Hologic was used for whole-body imaging, measuring lengths of body segments utilizing radiological expertise.
The study took place from January 2022 to September 2023 at the Department of Radiology at Chang Gung Memorial Hospital in Chiayi. Data acquisition was meticulously performed, with Kinect measurements requiring participants to move their limbs slowly for the device to capture the joints. DXA scans were analyzed by a radiologist with extensive experience in the field, ensuring accurate measurement of limb lengths.
The study also involved theoretical calculations to quantify body segment lengths obtained from both Kinect and DXA methods. Statistical analyses were conducted to validate the agreement between the two measurement techniques. The intraclass correlation coefficient (ICC) indicated high agreement in measurements, emphasizing the precision and reliability of the study’s findings.
Overall, the research employed cutting-edge technology and rigorous methodology to investigate body segment lengths in a specific demographic group, shedding light on the potential applications of Kinect and DXA technology in anthropometric studies. The study’s ethical considerations, detailed measurement procedures, and statistical analyses further strengthened the validity and credibility of the results obtained.
