Abstract
This study had been carried out with twelve stroke patients as its object for about three months from December 22, 2001 to March 19, 2002 in order to observe the recover of motor function and the change of SSE I´ in case of patients with cerebral paralysis. 1 ugI-Meyer, a tool which evaluates the function of locomotion, was used to measure the extent of recover of motor function.
After determining as the standard value the measurement of SSEP for 30 normal persons who were selected for comparison, I evaluated SSEP examination of stroke patients to find differences between two groups on the basis of the value.
I measured both the extent of recover of motor function and the results of SSEI´ examination once a month at the similar period for three months and, then, compared the results of two groups. Measuring them according to measure time, diagnosis, and lesion position resulted in the following conclusions
1. In regard to the recover of motor function according to the measure time, all patients of the experiment group displayed the remarkable extent of recover in all evaluations except the recovery of active movement of upper limbs (p<.05, p<.OI ), but they showed the decline of the motor function according to the measure time, especially in the evaluation of joint pain(p<.O1), passive movement of upper limbs(p<.O1), and passive movement of lower Iimhs(p<.01).
2. In regard to the recovery of motor function according to diagnosis, the patients displayed a certain degree of recovery in active movement of lower limbs(p<.O I ), capacity for movement(p<.01), and sensation of joint position(p<.O I), but the patients with cerebral infarction on the right showed the lowest degree of the recovery in passive movement of lower limbs and mobility, whereas those with cerebral hemorrhage on the right indicated the lowest degree of recovery in the sensation of_ joint position. 3. In regard to the recovery of motor function according to lesion position, they did not show noticeable recovery, and the position that displayed the lower degree of recovery than other parts was middle cerebral artery.
4. In regard to a general examination of SSEP for the experiment group, 10 out 12 patients(83.3%), as the largest number, displayed the abnormality in amplitude. L
5. In regard to SSEP examination according to the measure time, there was a phenomenon that the width of amplitude improved according to the measure time in case of amplitude 2(p<-01), but all the other results were normal values equivalent to the average values o1´ SSE1´ for normal people with the exception of the value of amplitue I a, which was measured before the treatment.
6. In regard to SSEP examination according to diagnosis, the results displayed noticeable differences in latency 2a, 3 & 4, interval la, amplitude la, and, finally, intcnsity(p<.05, p<.01), but all the other results were normal values close to the average values of SSEP for normal people aside from those of interval la and amplitude la of?cerebral infarction on the right and from that of amplitude la of cerebral hemorrhage on the left.
7. In regard to the SSEP examination according to lesion position, the results indicated a certain degree of difference in latency 2 & 3, interval 2 and amplitude I & 3(p<.01), but all the other results were normal values equivalent to the average values of SSEP for normal people except for all lesion position in the latency Ia and amplitude Ia of the middle cerebral artery.
8. According to SSEP examinations, the most results of amplitude la turned out to be abnormal(4 times),
whereas Just one result of both interval I a and latency I a was abnormal respectively, and, when these results were compared with those of diagnosis and lesion position, most results of cerebral infarction on the right and the middle cerebral artery were found to be abnormal.
As you see in the above-mentioned evaluation of the recovery of motor function, the patients showed the lowest degree of recovery of motor function in case of cerebral infarction on the right and the middle cerebral artery. As you observe in this study SSEP examination for Mr. }long(M/56) who developed cerebral infarction in the middle cerebral artery, there was no change according to the period in amplitude la that showed an abnormal value and it revealed the lowest degree of recovery of motor function as well. In light of Facts described above, it is expected that SSEP examination for stroke patients enables us to predict the recovery of motor function and it is considered that the evaluation of amplitude 1 a is particularly important
among SSEP examinations.
