Relations of Sit-to-Stand Performance to Lower Extremity Strength and Gait Ability in Stroke Patients

Abstract

We investigated the relationships between the performance test which employs the standing action (no. of repeats in 10 s) and knee extension strength and the 10 m walking time, with 44 hemiplegic patients as subjects. Significant correlations were found between the performance test and knee extension strength (non-hemiplegic side: r=0.67, p<0.01; hemiplegic side: r=0.75, p <0.01), and 10 m walking time (r=-0.75, p<0.01), and the reproducibility of the test was good. On the basis of the measurement of the number of stand repeats, the subjects were divided into 3 groups, and significant differences were found among knee extension strengths and 10 m walking times of the respective groups. Measurement of the performance test through the number of stand repeats within 10 s is simple, and it also has high reproducibility. Furthermore, since it is highly correlated with lower limb muscle strength and gait ability, we concluded that it is useful as an assessment method of functional movement ability of hemiplegic patients.
