Reprodutibilidade na avaliação da cinemática de um modelo multissegmentar do pé durante os testes de step down anterior e lateral

Abstract

The aim of the present study was to analyze the Oxford Foot Model (OFM) repeatability of healthy adults during two clinical tests: the Anterior Step down Test (ASDT) and the Lateral Step down Test (LSDT). Five healthy participants (one male, four females, 10 limbs in total), with a mean age of 22.2 (±4.7) years, were assessed in four sessions of tests using an interval of one week. Two independent examiners performed two sessions of each of the tests. For each session (intra-day), nine repetitions were carried out for each clinical test (ASDT and LSDT). After an interval of three hours, the data were collected once more. The tests were conducted after an interval of a week, using the same experimental conditions. The intra and inter-session repeatability of the range of motion of the foot was determined by the standard error of measurement (SEM) of each examiner and between the examiners. Differences between the test and the retest, as well as between the examiners, were assessed using the students t-test (p<0.05). The repeatability of the data was high for the two tests conducted. The SEM results were as follows: 0.26º to 1.59º for the intra-examiner assessment (ASDT); 0.28º to 1.31º for the inter-examiner comparison (ASDT); 0.02º to 1.03º for the intra-examiner assessment (LSDT); 0.28º to 1.00º for the inter-examiner comparison (LSDT). The OFM model was shown to be reproducible in terms of assessing the range of motion during functional tests (ASDT and DAS) in healthy adults.
