Outline of Final Research Achievements

The clinical measurement of range of motion (ROM) is a fundamental evaluation procedure of physical function. In this study, we developed a new ROM measurement system with a non-contact three-dimensional (3-D) surface scanner data in medical workstation. Then we investigated the reliability of a new ROM measurement with 3-D scanner. ROM measurement with a 3-D scanner was a better procedure than manual ROM measurement in terms of reliability. However, it was not nearly as fast as the manual measurement. Examiners must become familiar with the technique to improve speed. The non-contact 3-D surface scanner is a very useful tool, and in the future, it can be applied not only to ROM measurement but also to three-dimensional and sequential evaluations of joint deformation.
