Postural control among individuals with and without chronic obstructive pulmonary disease: A cross-sectional study of motor and sensory systems.

Individuals with COPD had a decreased postural control and several factors were associated with the impairments. The findings imply that the burden of tobacco smoking and reduced visual acuity relate to increased postural sway in quiet stance, and that muscle weakness is related to decreased limits of stability, among individuals with COPD.
