RESUMO
BACKGROUND: There was no uniform criterion for muscle force sense test of the sagittal plane of the ankle joint.OBJECTIVE: To explore the test-retest reliability of the ankle muscle force sense (MFS) under different target force.METHODS: The target force of the muscle was 25%, 50% and 75% maximal voluntary isometric contraction to measure MFS.Consistency degree of the repeated measures was evaluated by intra-class correlation (ICC) and standard error of measurement(SEM).RESULTS AND CONCLUSION: Interclass correlation coefficients of variable errors and absolute errors in MFS were more than0.75, and SEM of them were lower. ICCs of constant error of them were less than 0.75, and SEMs of them were greater. Thetest-retest reliability for variable errors and absolute errors of MFS was better when the target force was smaller.
