Pendulum Test on the Knee Joint in Normal Adults
|
|
|
|

Abstract
|
|
|
This study was performed to establish the normal values of the relaxation index and angular velocity through the pendulum test on the knee joint using an electrogoniometer. Fifty normal subjects participated in the study. The age ranged from 21
to
67
years old with 25 males and 25 females. Each subject was placed in a supine position and the electrogoniometer was attached to their knee joint. The leg was then dropped and the knee was allowed to swing passively.
The relaxation index was 1.678(0.090. The first angular velocity was 3.873(0.622 rad/s and the second angular velocity was 3.076(0.551 rad/s. There was no difference in parameters according to age or gender.
For more precise measurement of spasticity, analysis of the electromyographic signals recording simultaneously with pendulum test would be needed.
