Objectives: To evaluate the reliability of head and trunk acceleration measured by MTx sensors during walking on Level and Irregular surfaces and to compare the differences between healthy young
and old adults. Methods: Participants were 20 young female university students and 20 non-faller elderly women in Iran, 2013. Two MTX sensors were used to measure head and trunk accelerations in the vertical [VT] , anteriorposterior [AP] , and medial-lateral [ML] directions while participants walked on a 7-meter walkway.
Results: ICC values in young group were higher as compared to non- faller elderly group; ICC was greater than 0.7 for 89.47% [34/38] of variables in young group and for 60.52% [23/38] in non- faller. Intersession reliability for upper trunk coordination indices in regular surface and in young group showed highest values as compared with other conditions in both groups, whereas the lowest intersession reliability was found in irregular floor surface indices in non-faller elderly group.
