Relationship between the 10-Second Chair Stand Test (Frail CS-10) and Physical Function among the Frail Elderly

[Purpose] In this study, we investigated the utility of the Frail CS-10, a modified version of the 30-second chair stand test for the frail elderly, and the relationship between lower limb strength and walking ability in frail elderly persons. [Subjects] The subjects were 117 elderly persons, 54 men and 63 women, who were either frail or certified as in need of low levels of care with an average age of 77.9 ・ 9.0 years. [Method] We investigated the relationships among Frail CS-10, quadriceps femoris strength, walking speed and the Timed Up and Go (TUG) test by determining Pearson｡ｦs correlation coefficient for each gender. [Results] Significant relationships were found for both genders between Frail CS-10 and quadriceps femoris strength (as an index of lower limb strength) and walking speed and the TUG test (as an indices of walking and standing balance abilities). [Conclusion] The results suggest that Frail CS-10 is a simple and convenient test which reflects not only lower limb strength but also the walking and balance abilities of frail elderly subjects.Purpose: In this study, we investigated the utility of the Frail CS-10, a modified version of the 30-second chair stand test for the frail elderly, and the relationship between lower limb strength and walking ability in frail elderly persons.
