Abstract

ABSTRACT Introduction: <tt>In recent years, small and lightweight three-dimensional (3D) scanners have been used to measure circumference, surface area, and volume of the body or objects; however, their measurement reliability remains unclear. Therefore, this study aimed to clarify the reliability of measuring the circumference, surface area, and volume of a body part or an object using the handheld 3D scanner. </tt>Methods:<tt> Regarding the intra-rater reliability, one examiner measured and calculated the circumference, surface area, and volume of the upper arm of three participants. Regarding the inter-rater reliability, three objects were scanned by three different examiners, and the circumference, surface area, and volume were calculated. Intra-class correlation coefficients (ICC) were used to evaluate the reliability of 3D scanner (Artec Eva scanner) in this study. Study 1 investigated the intra-rater reliability ICC (1, 1), whereas Study 2 investigated the inter-rater reliability ICC (2, 1). </tt>Results: <tt>The intra-rater reliability, surface area 0.98, and volume ICCs are ICC 0.98, 0.98, and 0.99, respectively, whereas the inter-rater reliability, surface area, and volume ICCs are all 1.00, showing high reliability. </tt>Conclusion: <tt>This study suggests that the 3D scanner is a clinically efficient device for measuring the circumference, surface area, and volume of a body part or an object.</tt>
