GUZMAN, R. A et al. Correlation between the Scores of "Timed up and go" Test and Registered Joint Moments of Lower Limb During the Sit-to-Stand Transfer in Elderly with Antecedents of Frequent Falls. Int. J. Morphol. [online]. 2011, vol.29, n.2, pp. 521-525. ISSN 0717-9502. http://dx.doi.org/10.4067/S0717-95022011000200036.
The changes that take place during aging predispose the elder adult to frequent falls. In clinical practice fall risk is assessed by clinical tests that many times lack analytical power, therefore making it necessary to describe which of the clinical tests are related to the analytical biomechanical parameters in order to assign such characteristics to these functional tests. The objective of this work was to describe the existence of a correlation between the score of the functional test "Timed up and go" (TUG) and the joint moments of lower limb obtained during the execution of the sit to stand (STS) transfer in elderly subjects with a history of frequent falls. A sample of 30 volunteers was obtained; all were elders with a history of frequent falls. They were assessed with the functional test of TUG. Also assessed were the joint moments of the lower limb with motion analysis system. There is significant correlation (r=0.39; p=0.03) between the score obtained in the TUG and the maximum joint moment of the knee. For the sample assessed, the time of execution of the test "Timed up and go" was indicative of the capacity to generate a joint moment by the flexion-extensor muscles of the knee in subjects with a history of frequent falls.
