Background The sit-to-stand (STS) test has been deployed as surrogate measures of
strength or physical performance in sarcopenia diagnosis. This study examines the …

Background Ground reaction force during sit-to-stand motion is related to lower extremity
strength, and such measurements indicating weak muscle strength, may be linked to …

Background. Biologic changes are expected to occur prior to disability. Compared with
physical disability measures, measures of muscle impairment may be an earlier indicator of …

Background With increasing interest in addressing quality of life of older individuals, tests
such as the Functional Independence Measure (FIM) are widely used measures of infirmity …

Background The 5-times chair stand test (5CST) is a proxy tool for measuring physical
performance and muscle strength in diagnosing sarcopenia. The Asian Working Group for …

This study investigates the influence of chair height on the dynamics of sit-to-stand for two
age groups. Eleven young (25–36 years) and 10 older (61–79 years) adults participated …

The purpose of this study was to investigate the effect of ageing on body sway during sit-
tostand movement from a chair and on quadriceps muscle strength in the elderly population …

OBJECTIVE: The ability to stand independently and safely from the seated position is
essential for independent function. This investigation determined the relative contributions of …

Background and aims: Chair rise performance, which is simple to assess in a home or clinic
setting, has been used as a method of predicting leg power deficit in older adults. More …

Objective To investigate construct validity of linear encoder measurement of sit-to-stand
performance power in older people by showing associations with relevant functional …
