Quantitative analysis of postural control of individuals with COPD during activities of daily living (ATTRACTION) : a study protocol

International audienceBackground: Chronic obstructive pulmonary disease (COPD) is a common respiratory disease which is associated with the presence of numerous comorbidities. Among these, impaired postural control has been reported to be common. However, postural control has not been extensively studied in tasks of daily living, in this population. Novel solutions for postural control assessment exist, like the quantitative motion analysis, which has shown to be a robust and accurate tool. Objective: The main aim of this study is to characterise the postural control of individuals with COPD during tasks of daily living compared to the postural control of control subjects, using quantitative motion analysis. The secondary aims of this study are to examine the associations between postural control variables of interest and various clinical factors and to investigate the utility of the modified Glittre-ADL for the clinical assessment of postural control in daily tasks. Method: A case-control study will be conducted with sixteen individuals with COPD and a control group (n = 16). Quantitative movement analysis will be used to assess postural control during a modified test (incorporating tasks of daily living) and timed-up-and-go test (normal and dual-task conditions). Clinical factors (e.g., dyspnoea, pain, inspiratory muscle strength, falls, fear of falling, etc.) will also be assessed. Discussion: ATTRACTION will be the first study to propose the assessment of postural control in various daily living tasks in individuals with COPD using quantitative movement analysis and has the potential to precise the relationship between postural control and several clinical factors. Trial registration: ATTRACTION study was registered on ClinicalTrials.gov under the number NCT0521167
