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.
