RESUMO
The effects of motor cortex (MC) stimulation on post-stroke movement disorders were analyzed in 50 patients. These individuals either underwent MC stimulation primarily for the purpose of controlling their post-stroke involuntary movements (n = 8) or underwent MC stimulation for the purpose of controlling their post-stroke central pain (n = 42). In the latter patients, the effects of MC stimulation on co-existent involuntary or voluntary movement disorders were analyzed retrospectively. Good control of involuntary movements was observed in 2 of 3 patients with hemichoreo-athetosis, 2 of 2 patients with distal resting or action tremor, and 1 of 3 patients with proximal postural tremor. Subjective improvements in motor performance were reported by 8 patients who had mild motor weakness, and the effects appeared to be attributable to attenuation of rigidity. We consider that these findings justify further clinical studies on MC stimulation for the control of post-stroke movement disorders.

The patient was a 12-year-old girl with a skeletal class III malocclusion characterized by mandibular protrusion, a high mandibular plane angle, severe negative overjet and deep overbite. The patient's mandibular first premolar teeth were extracted following the standards of edgewise mechanotherapy. The total active treatment time was 19 months, however, retention was needed until the patient was 19 years old. The malocclusion has been treated satisfactorily resulting in correction of the functional and esthetic flaws without orthognatic surgery.
