Motion assessment instrument

Abstract

A hand-held, portable goniometer apparatus is disclosed. A stream of LiDAR data comprising a plurality of dots in three-dimensional co-ordinate space is captured, relating to anatomical features of a subject. These are analysed to determine angles, and e.g. speeds of movement, the angles matched against a database storing movement information for anatomical features. Video images of the subject may also be captured. A protractor may be generated which indicates an angle, and an animated image of an identified structure may be generated. Where a detected angle lies outside a predetermined range, this may be detected. Also disclosed are methods of determining a range of movement of a subject, and identifying if a subject’s posture is correct and alerting them if not.
