Abstract
Background and purpose: The Timed Up and Go test (TUG) assesses dynamic balance performance. Motion sensors such as gyroscopes have enabled evaluation of the various subtasks of the TUG such as the 180° turn. As fast turning triggers the vestibular system, we hypothesize that the 180° turn is sensitive to change in individuals with unilateral vestibulopathies (UVP). Therefore, the objectives of this study were to formulate the minimal detectable change and minimal clinically important difference (MCID), both anchor- and distribution-based, for the 180° turn time in individuals with UVP.
Methods: In this longitudinal prospective study, data were collected in secondary and tertiary hospitals. Participants were included up to 4 weeks after the onset of the UVP. Unilateral vestibular function loss was confirmed by the criteria of the Bárány society. At baseline and follow-up (10 weeks since onset), participants performed an instrumented version of the TUG and a tandem gait test. An anchor- and distribution-based MCID was calculated for the 180° turn time.
Results: Seventy participants (55 ± 17 years, 35 female) were included. A minimal detectable change of 0.69 s (180° turn time) was calculated. The anchor-, and distribution-based MCID were 0.71 and 0.63 s for the 180° turn time, respectively.
Discussion: In individuals with UVP, an MCID of 0.71 s was observed for the 180° turn time. More research is recommended to confirm our results.
Trial registration: clinicaltrials.gov under ID NCT04979598.
期刊介绍：
Physiotherapy Research International is an international peer reviewed journal dedicated to the exchange of knowledge that is directly relevant to specialist areas of physiotherapy theory, practice, and research. Our aim is to promote a high level of scholarship and build on the current evidence base to inform the advancement of the physiotherapy profession. We publish original research on a wide range of topics e.g. Primary research testing new physiotherapy treatments; methodological research; measurement and outcome research and qualitative research of interest to researchers, clinicians and educators. Further, we aim to publish high quality papers that represent the range of cultures and settings where physiotherapy services are delivered. We attract a wide readership from physiotherapists and others working in diverse clinical and academic settings. We aim to promote an international debate amongst the profession about current best evidence based practice. Papers are directed primarily towards the physiotherapy profession, but can be relevant to a wide range of professional groups. The growth of interdisciplinary research is also key to our aims and scope, and we encourage relevant submissions from other professional groups. The journal actively encourages submissions which utilise a breadth of different methodologies and research designs to facilitate addressing key questions related to the physiotherapy practice. PRI seeks to encourage good quality topical debates on a range of relevant issues and promote critical reflection on decision making and implementation of physiotherapy interventions.
