P 106 - Intra- and inter-operator reliability of a novel hand protocol during grip movement in healthy subjects

Abstract

Quantitative and qualitative measures of human movement can be two important features for clinical decision making. The purpose of this study is to evaluate the Intra-and inter- operator reliability of a novel hand protocol during grip movement. The experimental protocol required the positioning of 8 optoelectronic cameras and 24 markers. 5 healthy subjects have been recruited. Each subject received 2 markerizations by two different operators (A and B) and they carried out 3 tests at a time T0 and at a time T1 (a week after) for each markerization. Results have shown that Test-retest reliability of the markers positions measurements was good (test: 0,893, p < 0.001; retest: 0,773, p < 0.01) and intra-operator reliability was excellent (A: 0.983, p < 0.001; B: 0.993 p < 0.001). Overall, these results suggest that this protocol is reliable in order to develop future studies for its application in clinical practice.
