Reduced Quadriceps Motor-Evoked Potentials in an Individual with Unilateral Knee Osteoarthritis: A Case Report

Figure 2

Stimulus response curves at the baseline testing session produced by calculating average MEP magnitudes at TMS stimulus intensities equal to 115%, 120%, 125%, 130%, 135%, and 145% of the active motor threshold (AMT) for each limb. Values are represented as a normalized percentage of the average MEP amplitude calculated at 105% of the AMT for the affected limb (squares and solid lines) and unaffected limb (diamonds and dashed lines). Thick lines correspond to the first baseline testing session (before the initial 30-minute exercise session), while thin lines correspond to the second baseline testing session (immediately following the initial 30-minute exercise session).
