Influence of Postural Control and Cognitive Functions on Care-level

Abstract

[Purpose] This study investigated the effects of postural control function and cognitive function according to care levels. [Subjects and Methods] A total of 107 elderly people who used day care services were classified into three care-level groups. Postural control function and cognitive function were assessed, and multiple regression analysis and inter-group comparisons were performed. [Results] The results suggest that care level is related to both postural control function and cognitive function, and that postural control function is a factor related more strongly with care level than is cognitive function. There was a significant difference in postural control function between the requiring-help group and the mild long-term group, and between the requiring-help group and the moderate long-term group. There was also a significant difference in cognitive function between the requiring-help group and the mild long-term group, and between the mild long-term group and the moderate long-term group. [Conclusion] Both postural control function and cognitive function influenced the care level. Additionally, the relationships with care level suggest that postural control function declines ahead of cognitive function.
