Every locomotion activity is performed by the coordination of different lower limb muscles. Electromyogram (popularly known as the EMG) is the measure of the biological potentials associated with muscle activity. Cross correlation and regression are favorable mathematical tools to quantify the kind of coordination between the muscles of lower extremities. The aim of this study is to quantify the coordination between dominant knee ankle muscles in performing specific locomotion activities with healthy subjects. The results will help to propose a mathematical model for the significant and active muscle groups. The results, shows that the SOL-GST (Soleus and Gastrocnemius) has highest level of coordination for the locomotion activities studied. The results can be employed in aiding the disabled and developing adaptive knee prosthesis/ orthosis and in joint replacement in the near future. The study is further being continue to test fatigue analysis and with the different category of patients. The research also has a good potential for sports science and medical applications. This results in accelerated innovation that significantly improves the quality of designs, and hence enhances the quality of life for the patient.
