Usefulness of Measurement of Paravertebral Muscle Function Using 3D-
Objective: To evaluate the validity of measuring paravertebral muscle function with 3D- NEWTON® by assessment of correlation among Biodex and surface EMG.
Method: Nineteen healthy adults were participated. The function of their paravertebral muscle was measured by three ways. By 3D-NEWTON® the maximum enduration time was measured by second when 3D-NEWTON® was fowardly inclined for the extensor function, and backwardly inclined for the flexor function. By surface EMG maximum muscle activity was obtained from eractorspinae and rectus abdonimis during 3D-NEWTON®measurement. Maximum muscle activity was the mean activity of 10 seconds when the root mean sequared firing data was highest. By Biodex® peak torques of extensor and flexor were measured by isometric exercise. The correlation coefficiencies among data from 3D-NEWTON®, surface EMG and Biodex® were calculated using the Spearman correlation coefficiency. These data were analyzed statistically using SPSS v13.0.
