Abstract: 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.

Keywords: muscle coordination; cross-correlation; EMG; electromyogram; gluteus maximus; iliopsoas; lower limb muscles; locomotion; walking; hip-thigh muscles; disabled; disabilities; adaptive prostheses.
