Abstract: Parameterising the single leg stance test could be useful in clinical practice and basic research. The aim of the present study was to understand the inter-group and intra-group differences in kinematic variables among young adults and older adults in the performing of single leg stance test. Two groups of participants were measured, six individuals over 65 years old and six individuals between 20-25 years old. Inertial sensors were located in the trunk and in the lumbar zone. Significant differences between groups were found in the lumbar and trunk sensor in different movements (flexo/extension, inclination and rotation). Significant differences between the dominant and non-dominant leg were not found. There were significant differences between both groups. It is also important to highlight the excellent values of reliability of the inertial sensors.
