Abstract
Frailty has been described as a clinical state of vulnerability to stress, consequence from decline of resilience and physiological reserves and progressive decline on ability of homeostasis maintenance. The aim of this study was to evaluate the complexity of R-R intervals (RR) in resting supine (REST) and standing (STAND) position in 3 groups: frail, pre-frail and non-frail. Eighty older people (60-94 years old) were divided into frail group (n = 6), pre-frail (n=36) and non-frail group (n=38). The RR series were recorded at REST and during STAND for 10 minutes in each position. Short sequences of RR were analyzed by conditional entropy (CE) and approximate entropy (ApEn). Position, group and interaction effects were evaluated by two-way repeated-measures ANOVA. CE indicated only position effect while ApEn showed only group effect. ApEn seems to be more suitable for assessing changes in the complexity in frailty syndrome.
