Coordination between lower limb muscles in different locomotion activities

Locomotion activity is performed by the coordination of lower limb muscles. Cross-correlation is a mathematical tool to quantify the coordination. This study quantifies the coordination between hip-thigh muscles, using EMG (Electromyogram), in performing specific locomotion activities. Hip-Thigh muscles are the initial active muscles for general routine locomotion activity and hence their coordination gives a well insight to visualise the performance. The results show that the IL-GM (Iliopsoas and Gluteus Maximus) has highest level of coordination in almost all types of examined locomotion activities. The results can be employed in aiding the disabled and developing adaptive prosthesis.
