A Cross-Sectional Study on Balance Deficits and Gait Deviations in COPD Patients

Table 4

Spearman’s rank correlation coefficient between Fev1% and balance parameter for COPD participants.

Balance parameter	r	value
NSEC-AP (mm/sec)	0.14	0.39
NSEC-ML (mm/sec)	0.15	0.92
NSEC-VM (mm^2/s)	0.25	0.10
NSEO-AP	0.23	0.80
NSEO-ML (mm/sec)	0.20	0.73
NSEO-VM	0.38	0.65

NSEC-AP: normal standing eye-closed anteroposterior sway velocity. NSEC-ML: normal standing eye-closed mediolateral sway velocity. NSEC-VM: normal standing eye-closed velocity moment. NSEO-AP: normal standing eye-open anteroposterior sway velocity. NSEO-ML: normal standing eye-open mediolateral sway velocity. NSEO-VM: normal standing eye-open velocity moment. No significant correlation observed between balance parameter and Fev1%.
