Abstract

Background and Objective: The older adults are aged at increased risk of falling due to decrease in the knee extensor muscle strength that is one of risk factor of falling in elderly. Thus, the assessment of the strength of the knee is very important. Therefore, the purpose of this study was to define the prediction equation of knee extensor muscle strength from the performance of 5 time sit to stand test (5-STS) and demographic data variable.


Method: Fifty-six healthy elders (mean age 67.59 ± 7.35 years) (28 males and 28 females) who aged more than 60 years were asked to provide the demographic data and performed 5-STS. All participants were evaluated knee extensor strength by Push-pull dynamometer. The multiple regression analysis was used to explore knee extensor strength prediction equation and significant levels were set at p < 0.05.


Results: The results showed that the knee extensor strength prediction equation were established by variables obtain from gender, weight and time to complete 5-STS, knee extensor strength = 39.055 + 5.349 (gender) + 0.150 (weight) – 2.981 (time to complete 5-STS) ± 4.37 kilograms, with high correlation (r = 0.891) and 78.2 percent of power of estimation. This equation had an error of estimation about 4.37 kilograms.


Conclusion: The gender, weight and time to 5-STS were the factors which influence knee extensor strength and could be used to predict knee extensor strength in elderly adults.
