The influence of cognitive load on static balance in chronic obstructive pulmonary disease patients

Abstract

Patients with chronic obstructive pulmonary disease (COPD) have an increased risk of falling and hip fractures, compared to healthy subjects. 1 Beside the direct consequences of the fall, this increased risk has an indirect negative effect in COPD patients, likely due to increased stress, dyspnea, quality of life, and sociability, ultimately leading to reduced physical

Impairment and characteristics of postural control sub-components in people with COPD: a scoping review

“…Main COP variables used were area, velocity (in both anteroposterior (AP) and mediolateral (ML) directions), variability (AP and ML directions), and amplitude (AP and ML directions). Significant differences compared to healthy subjects were identified for each of these parameters, but results were heterogenous between studies [27–29,32,33,35,36,39–43,47,49]. The reported correlations between “static stability” and clinical factors are summarized in table 2 .…”

“…Nineteen studies used force platform measurements including an important variety of centre of pressure (COP) parameters [27][28][29]32,33,35,36,[39][40][41][42][43]47,49,56,58,59,61,62]. Main COP variables used were area, velocity (in both anteroposterior (AP) and mediolateral (ML) directions), variability (AP and ML directions), and amplitude (AP and ML directions).…”

Impairment and characteristics of postural control sub-components in people with COPD: a scoping review

“…Evidence on this component was sparse, and only few studies offered the opportunity to isolate information on cognitive influences and postural control of COPD patients. Cognitive tasks impair postural control performance in both COPD and healthy subjects [39,49,72]. Two studies [49,72] showed no supplementary effect of the cognitive task in COPD patients compared to controls while Morlino et al [39] found the opposite.…”
