Analysis of Postural Control of COPD Patients (ATTRACTION)

Conditions
Chronic Obstructive Pulmonary Disease
Interventions
Other: quantified analysis of postural control during activities of daily living
Registration Number
NCT05211674

Brief Summary

Chronic Obstructive Pulmonary Disease (COPD) is a common chronic respiratory disease, causing disabling respiratory symptoms and impairing patients' quality of life. Currently one of the leading causes of death worldwide, COPD is a major socio-economic concern. It is also accompanied by extremely frequent extra-respiratory manifestations (or co-morbidities). Among these secondary manifestations, the equilibrium of these patients is subject to modifications: thus, numerous studies have shown that the equilibrium of COPD patients was altered compared to healthy age-matched subjects. This alteration is associated with a greater functional limitation and a higher risk of falling. Although this impairment has been demonstrated clinically, the balance of these patients has never been analysed using quantified movement analysis tools during tasks similar to those performed in daily life. Moreover, the underlying mechanisms remain unknown and the possible associations with several clinical factors of interest (pain, dyspnea, muscle function...) have not yet been assessed. The hypotheses of this project are that (1) the postural control of COPD patients is altered compared to healthy subjects during tasks of daily living and these changes can be characterised. (2) Several clinical factors are associated with these changes.
