1. Análise temporal da relação entre o tremor fisiológico cinético e o envelhecimento com base em desenhos digitalizados da espiral de Arquimedes
O tremor humano é o distúrbio mais comum do movimento caracterizado por movimentos repetitivos e esteriotipados, sendo os idosos a população mais afetada. O movimento causado pelo tremor pode estar associado a diversos fatores, tais como disfunções neurológicas ou, até mesmo, a processos naturais. Neste último caso, diz-se que o tremor é fisiológi

2. Visual and mechanical control of postural and kinetic tremor in cerebellar system disorders.
The influence of alterations in visual guidance and somaesthetic sensory inputs was studied in five patients with kinetic and postural tremor characteristic of cerebellar impairment. The patients performed wrist flexion-extension movements or movements about the shoulder with or without visual guidance. Different types of mechanical loads were applied to opp

3. Tremor disorders. Diagnosis and management.
Tremor is commonly encountered in medical practice, but can be difficult to diagnose and manage. It is an involuntary rhythmic oscillation of a body part produced by reciprocally innervated antagonist muscles. Tremors vary in frequency and amplitude and are influenced by physiologic and psychological factors and drugs. Categorization is based on position, po

4. Tremor after head injury and its treatment by stereotaxic surgery.
Tremor, both postural and kinetic may be a late complication for victims of severe closed head injury, especially in the young, and may add to their disability. The nature of the tremor is described in eight patients. In each a stereotaxic thalamotomy was performed, dramatically relieving or reducing the severity of tremor in each instance, and resulting in

5. Genetic essential tremor in γ-aminobutyric acidA receptor α1 subunit knockout mice
Essential tremor is the most common movement disorder and has an unknown etiology. Here we report that γ-aminobutyric acidA (GABAA) receptor α1–/– mice exhibit postural and kinetic tremor and motor incoordination that is characteristic of essential tremor disease. We tested mice with essential-like tremor using current drug therapies that alleviate sym

6. Bilateral cerebellar dysfunctions in a unilateral meso-diencephalic lesion.
The clinical syndrome of a 65-year-old patient with a slit-shaped right-sided meso-diencephalic lesion was analysed. A cerebellar syndrome with limb-kinetic ataxia, intention tremor and hypotonicity in all extremities as well as ataxic dysarthria was found. The disruption of the two cerebello-(rubro)-thalamic pathways probably explained the signs of bilatera
