On the other hand it is known that patients suffering from chronic respiratory diseases such a chronic obstructive pulmonary disease have balance problems [2]. There is currently a lack of information about balance perturbations of patients with PF. Yet during activity of daily living these two tasks must often be realized simultaneously (e.g. talk on the phone while walking). One or both tasks can be negatively impacted and the risk of fall is increased. There is currently a lack of affordable tools to quantify the impact of cognitive task on balance of patients with PF. Therefore the aim of this study is to evaluate the effect of a cognitive task (CT) on balance of patient suffering from PF. Method: 5 PF patients (68 (17) years old, FEV1 = 85 (2) %) and 12 control subject matched in age, weight and height participated in the study. They performed two CT (counting task and naming) under two conditions: eyes open (YO) and eyes close (YC). Each trials last for 60s, the balance was recorded and quantified using a Wii Balance Board, this device can be used as a reliable and valid tool for assessing standing balance [3]. Results: Multifactor ANOVA for the different parameters extract from center of pressure displacement, the conditions and the tasks were computed. There is a very highly significant effect of the pathology and the cognitive tasks. Interactions for all parameters were found for the CT and the pathology. Individuals results are presented in Table 1. Conclusion: The effect of a CT is important on the balance of patients with PF. It seems that patients pay more attention on the CT than on the balance. This is important for the evaluation of fall risk in those patients.
