Abstract The objective of the investigation who gave as result this work was to investigate the effectiveness of kinaesthetic motor imagery in the activation of the hemiplegic hand muscles following stroke. The experiment consisted of two random groups. Movements were measured after treatment. The participants were ten patients with hemiplegic hands (men who mean age was 74.4 years; mean time since stroke 3.05 months). All patients received three sessions of physical treatment based on an identical treatment protocol. Five patients were randomly assigned to an experimental group practising kinaesthetic motor imagery of a grasp using the 'lumbrical action' (experimental group). The others five (control group) followed a relaxation script. All the patients were then asked to grasp an object using the 'lumbrical action'. The grasps were recorded using an optoelectronic motion capture system. The magnitude of the extension of the index finger and the correlation of the angular displacement of the proximal phalangeal joints and the metacarpophalangeal joints were calculated. The movement time for the whole grip was calculated. The experimental group demonstrated higher extension in the index finger (p = < 0.01) and they had a higher correlation coefficient (0.99) than the control group (0.77) for the displacement of the proximal interphalangeal joint and the meta-Rev.

O tempo de movimento foi calculado para o agarramento. O grupo experimental mostrou extensão no índice mais alto (p = < 0.01) e teve um coeficiente de correlação superior (0,99) ao grupo de controle (0,77) para o deslocamento angular das articulações metacarpofalângicas e intefalângicas próximas. O tempo do movimento para o grupo experimental foi mais rápido, ainda que a diferença não foi significativa. Palavras chave: enfermidade cérebro-vascular, hemiplegia, mão, imagem motora.
