Differential Corticomotor Excitability Responses to Hypertonic Saline-Induced Muscle Pain in Forearm and Hand Muscles

Figure 5

Correlations between percentage change in MEP magnitude versus peak pain intensity. No significant associations were found between percentage MEP changes from baseline at peak pain, with peak pain intensity for either the (a) ECR MEPs during ECR pain, (b) ECR MEPs during FDI pain, (c) FDI MEPs during ECR pain, or (d) FDI MEPs during FDI pain.
