Review of the psychometric properties of lower limb motor coordination tests

Resumo

Introduction: Adequate motor coordination (MC) of the lower limbs is essential for most of the motor tasks. Therefore, it is important to know the psychometric properties of the tests employed to assess lower limb MC, so that professionals could have a better basis to choose the most adequate assessment tools. Objectives: To investigate the psychometric properties and clinical utility of instruments used to assess lower limb MC, by means of a critical review of the literature. Materials and methods: A search was conducted in six databases looking for studies which evaluated reliability, validity, sensitivity to changes, or clinical utility of the tests employed to assess lower limb MC. The articles were assessed and the data of their psychometric properties were extracted by two researchers, independently. Results: The search returned 1361 studies, 1,325 were excluded after analyses. The hand search yielded four eligible articles, totaling nine included articles. The included studies evaluated the psychometric properties of eight tests, but only three were specific to assess lower limb MC and the others were sub-items of other scales, which assess other domains. None of the tests provided data for all of the basic psychometric properties. Final remarks: According to the results of this review, none of the tests had their basic psychometric properties reported, which is necessary to be investigated in future studies. This review may facilitate the search and selection of lower limb MC tests by researchers and clinicians.
