Postural Control in Chronic Obstructive Pulmonary Disease

Postural control impairment is common in people with COPD (pwCOPD), which can increase the risk of falls and affect quality of life. However, the majority of existing studies examine this postural control in isolation, without taking into account the cognitive demands that occur during activities of daily living during which individuals are often required to perform a mental task while maintaining their balance. This research aims to fill this gap by studying how a cognitive task can influence postural control in pwCOPD. We hypothesized an impaired postural control in pwCOPD compared to healthy individuals, which would be exacerbated in presence of a cognitive task.

This observational study is based on the analyses of data (center of pressure displacement) recorded during the first visit of NEUROTIGUE study (NCT04028973). Center of pressure (COP) displacement were recorded during 60s of static balance in four conditions (random order) : * Eyes open without cognitive task * Eyes open with cognitive task * Eyes closed without cognitive task * Eyes closed with cognitive task The cognitive task used was a working memory task : the 1-back task. COP displacement will be assess using a conjunction of parameters to provide a comprehensive understanding of postural control (e.g., amplitude, standard deviation, non-linear approaches).
