Effect of Inspiratory Muscle Training on Posture in Chronic Obstructive Pulmonary Disease Patients

Faculty of Medicine, Sousse34 enrolled

Overview

Chronic obstructive pulmonary disease (COPD) is a respiratory disease that results in progressive airflow limitation and respiratory distress. Physiopathological features of COPD suggest that people who suffer from this disease have many risk factors for falls that have been identified in older individuals. Risk of falls is multi-factorial and impaired balance has been shown to contribute. The investigators aimed to demonstrate that, IMT performed during a PRP may improve Postural control in COPD patients.

Chronic obstructive pulmonary disease COPD is a preventable and treatable disease. According to the WHO, COPD would be the third leading cause of death by 2030. This disease is characterized by airflow limitation that is not fully reversible. The airflow limitation is usually progressive and associated with an abnormal inflammatory response of the lung to noxious particles or gases. However, emerging data showed that COPD patients demonstrate important deficits in balance and control which associated to a high risk of fall. Individuals with COPD, especially those with inspiratory muscle weakness, increased their reliance on ankle muscle proprioceptive signals and decreased their reliance on back muscle proprioceptive signals during balance control, resulting in a decreased postural stability compared to healthy controls. These proprioceptive changes may be due to an impaired postural contribution of the inspiratory muscles to trunk stability. Inspiratory muscle training (IMT) has been shown to be an effective modality for COPD patients for improving the maximal inspiratory muscle strength, the dyspnea and health-related quality of life. However, the effect of inspiratory muscle training on postural control is not studying. The purpose of this study is to evaluate the effect of the inspiratory muscles training on posture in COPD patients.

Outcomes

Primary Outcomes

Balance outcomes

Balance were measured by stabilometry to evaluate postural control in COPD patients. Two principals variabels were evaluated: the center of pressure in the mediolateral direction (CoP ML) ; the center of presure in anteroposterior direction (CoP AP).

Time frame: Basline, After 2 months
