Fig. 3From: A biomedical Engineering Laboratory module for exploring involuntary muscle reflexes using ElectromyographyElectromyographic Response to Electrical Simulation of the Tibial Nerve. Plot representing the average Soleus muscle response at the sensory, motor, and maximum tolerable stimulation intensities. At the sensory threshold, no H-reflex was observed. The motor threshold evoked an M-wave in all 8 students and three participants also elicited an F-wave response at the maximum tolerable thresholds. With increasing stimulation intensity, there was a visibly larger amplitude response. Shaded regions represent ± SEMBack to article page
