Figure 5

Epidural electrical stimulation (EES) evoked motor responses. (A) Early response (ER) and middle response (MR) representative responses recorded in BF, TA and SOL muscles at different stimulation intensities (1.75–3.5 mA) in subject 2 using the multi-contact rod array. Each trace is the average of ten motor evoked responses. Dotted lines indicate the beginning of the first deflection corresponding to ER. Continuous lines indicate MR. Examples of the peak-to-peak amplitude measurements for both ER and MR are shown at the bottommost traces (3.5 mA). (B) Recruitment curves showing ER (black dots) and MR (white dots) responses as shown in (A). Note the different scales. Abbreviations: BF, Biceps femoris; TA, tibialis anterior and SOL, soleus.
