Abstract

In this paper we analysed the signals of Gastrocnemius (GST) and Soleus (SOL) calf muscles from a unilateral clubfoot patient (right leg normal and left clubfoot) during different stages (resting, flexion and extension) using EMG. The Raw and filtered [Root Mean Square (RMS) and Integrated EMG (IEMG)] signals acquired from the subject were quantified using (AcqKnowledge 3.9, BIOPAC MP-100 systems Inc.), for 120 seconds and the output was analysed using paired sample T-test. Significant differences were observed between the Root Mean Square (RMS) EMG and Integrated EMG (IEMG) muscle activity of normal and clubfoot leg during the three conditions for both GST and SOL muscles. With the mathematical modelling tools, the results were studied and was found that the calf muscle activity of affected leg varies from the normal leg during resting, flexion and extension stages. It was also studied and proved that relapses can occur even after surgical correction (Achilles tenotomy) on these patients with the accuracy of 80%.
