ABSTRACT
The aim was to determine if patients with writer' cramp (WC) have abnormalities in kinesthetic motor imagery of hand movements. We timed the execution and simulation of a "finger tap task" and a "writing task" in 9 patients with simple WC and 9 matched healthy controls. In the "finger tap task, patients tended to be slower than controls to execute without vision (p=0.190) and to simulate the movements (p=0.094). In the "writing task", patients were slower than controls to execute writing with vision (p=0.0001) and without vision of the movements (p=0.0001) and to mentally simulate it (p=0.04). Patients were slower to execute writing than to simulate it (p=0.021) In general, there were not significant correlations between times of execution and simulation of both tasks. In conclusion, patients with WC seem to have slowing in the processes of mental simulation of hand movements that is not specific for writing.
RESUMO
O objetivo do estudo foi determinar se pacientes com cãibra do escrivão (CE) teriam anormalidades na imagem motora de movimentos manuais. Foi cronometrado o tempo gasto para a execução e simulação de uma tarefa de "batida dos dedos" e outra de "escrita" em 9 pacientes com CE simples e 9 controles pareados. Na tarefa de "batida dos dedos" os pacientes apresentaram tendência a serem mais lentos que os controles para executá-la com visão dos movimentos (p=0,190) e para simulá-la (p=0,094). Na tarefa de "escrita", os pacientes foram mais lentos que os controles para executá-la com visão (p=0.0001) e sem visão dos movimentos (p=0,0001) e também para simulá-la (p=0,04). Os pacientes foram mais lentos para escrever que para simular a escrita (p=0,021). Não encontramos correlação entre os tempos de execução e simulação das tarefas. Pacientes com CE apresentam alentecimento no processo de simulação mental de movimentos manuais.
