A Study on Lower-Limb Muscle Activities during Daily Lower-Limb Motions
نویسندگان
چکیده
The lower-limb muscle activities during the daily lower-limb motions such as sitting down, standing up, squatting, walking, ascending and descending stairs motions have been studied to enable power-assist robotic systems to estimate human lower-limb motions based on muscle electromyographic (EMG) signals. The relationship between the lower-limb motions and the activity levels of main muscles concerning the daily lower-limb motions are analyzed in this study. The human intention for lower-limb motion can be estimated based on the activation pattern of lower-limb muscles. The analyzed results would be used to design the controllers of the lower-limb power-assist robotic systems for physically weak persons.
