Investigation Of The EMG-Angle Relationship In The Upper-Limb Muscles During Isometric Contraction

The relationship between EMG and elbow angle was investigated to identify the signal characteristics of upper-limb muscles during isometric contraction.The study would improve the current understanding of electrophysiological activities of the human upper limbs, which would aid the development of pr...
