An Evaluation about Effect of Stroke on the Sensorimotor Performance of the Unaffected Upper Extremity / 中国康复理论与实践

ABSTRACT

@# The main objectives of this study was to compare the sensorimdt afar Performance of the unaffected upper extremity of elderly stroke patients with that of healthy elderly people. Methods: The groupof stroke patients was of 30 hemiplegic subjects who had had a cerebrovasculai accident at least 6 monthsearlier. A group of 30 healthy subjects matched for age and sex was used for comparison. The main parameters of the performance of the unaffected upper extremity of the stroke subjects and of the same side of the healthy subjects were measured with valid,reliable instruments. Some variables potentially related to theunaffected upper extremity were also measuredlength of time since the stroke,activity level,etc.Results;Statistical analyses showed significant deficits in the unaffected upper extremity of hemiplegic subjecs compared with normal subjects with regard to the following parameters gross manual dexterity, fine manualdexterity, motor coordination,global performance (P<0. 05 to P<0. 0001 ). No significant clinical or statistical difference was found for grip strength,two-- point discrimination and kindethesia.-- Conclusions: Manyfactors (frequency of use of the unaffected hand sensorimotor interaction task,sevrity of the the deficits in corticifugal projection and deficits in postural stabilization)could interact to provide the clinical picture obtainedin the present study.
