Objectives: The objective of this research was to verify if there was a variation in the MFC (Minimum Foot Clearance) value among elderly with and without history of falls and, if there were any, verify which joint of the lower limb was responsible for that variation. It was also a main objective to verify if there was a correlation between the risk of falling, achieved through the Timed Up and Go Test (TUG), and the MFC variation. Material and Methods: The sample consisted of a total of 30 elderly who met the inclusion and exclusion criteria. These were divided into the group without history of falls (n=15) and into the group with history of falls (n=15). The MFC and the joint movement amplitudes of the hip, knee and ankle, of the dominant lower limb, were assessed using the Kinovea programme and for the risk of fall assessment it was used the TUG. Results: There were no statistically significant differences in the MFC and TUG values between the groups with and without history of falls. However, there is a decrease of the MFC value for the group with history of falls, being the ankle the joint that most contributed to the MFC variation in the group without history of falls, and the knee in the group with history of falls. About the relation between MFC and TUG, it was obtained a negative correlation (r=-0,269) but it was not significant (p=0,150). Conclusion: In our sample no significant differences in the MFC value were obtained between the group with history of falls and the group without history of falls. Besides the lack of significant differences in the MFC value it was determined the articulation of the lower limb responsible for its variation, and it has been found, although with a p>0,05, that for the group with no history of falls it was the ankle that more contributed to this variation and the knee to the group with history of falls. Concerning to the TUG and MFC value correlation it wasn’t significant. Thus, it was concluded that the TUG use is more effective and sensitive in predicting the risk of falling when compared with the kinematic analysis to obtain the MFC value and the joints amplitude.
