Une nouvelle methode de mesure de longueurs segmentaires A new segment length measurement method

摘要

Aims. - To develop a faster segment length measurement method than the classical one proposed by the ISAK without modifying the nature and accuracy of the measurements.Methods. - Nine segment lengths were chosen and evaluated in 12 subjects with the ISAK method as the "gold standard". The method proposed herein included the marking of anatomical landmarks on the skin and the scanning of these landmarks with a digitizing arm used in computer aided design of mechanical parts. In order to obtain acceptable data, the subject had to stand in a stabilizing device conceived exclusively for this purpose.Results. - Paired T-tests between data collected from both methods indicates that a significant difference exists only for the forearm measurement (P = 0.009). The new method is therefore adequate for all segment lengths except at the forearm, where prosupination must be standardized.Conclusion. - The time saved with this new method, which is its main advantage, was estimated at 42% in these settings and increases with the number of length measurements on each subject. The proposed method is thus well suited for large measurement volumes or if the time spent with the subjects implies significant costs.
