Abstract

1) Objective: to evaluate the effects of excitatory transcranial magnetic stimulation of the anterior intraparietal area in chronic patients with a frontal lesion and parietal sparing due to stroke on the impaired upper (UL) and lower limb (LL) as measured by Fugl-Meyer Assessment (FMA). 2) Methods: three patients (P1: 49.83/2.75, P2: 53.17/3.83, P3:63.33/3.08 years-old at stroke/years post-stroke, respectively) received two weeks (five days/ week) of rTMS at 10 Hz of the left anterior intraparietal area (AIP). A patient was treated in similar conditions with a sham coil (56.58/4.33) No complimentary therapy was delivered during the study. Patients were evaluated before, after- and two-months post-treatment (A1, A2 and A3, respectively). 3) Results: We found increased scores for lower limb in motor function subsection for P1 and P3 and in sensory function for P2 by A2 that remained at A3. We also found an increased score for upper limb motor function for P2 and P3, but the score decreased by A3 for P2. P3 score for upper limb ROM increased by A3 compared to A1 and A2. 4) Conclusion: AIP excitatory rTMS increased the FMA scores for lower and upper limb function, showing a broader effect when compared to M1 stimulation.
