MUSCLE ACTIVITY DURING GAIT ON A TREADMILL: A COMPARISON BETWEEN ANTERIOR CRUCIATE LIGAMENTS (ACL) AND NORMAL SUBJECT'S

Abstract

The aims of this research are to investigate and compare the muscles activity during gait on a treadmill for ACL subjects who underwent surgery and did not undergo surgery, and comparing them with normal subjects. The question that need to be solved is do the ACL subject who underwent or did not undergo surgery shows similar muscles force compared to normal subject? Walking activity of 12 subjects on a treadmill were captured using Vimn Nexus system and electrompgraphy (EMG) and analyzed. As a result, the comparison between ACL subjects shows that subject who underwent and did not undergo surgery used mainly soleus and gluteus maximus muscles, similar to normal subjects but the muscle forces produced were different. Besides, range of all ACL subjects' muscles who went through surgery was found to be similar to normal subject's.
