RESUMO
@#Objective To study the effect of electroencephalograph (EEG) bionic electrical stimulation at Wangu (GB12), Tianzhu (BL10), Neiguan (PC6) on cerebral blood flow and metabolism in patients with persistent vegetative state (PVS). Methods 60 patients with PVS were divided into observation group (n=30) and control group (n=30) according to the random number table. The control group received routine treatment, including basic management, hyperbaric oxygen therapy, awaking medicine, sensory stimulation, and so on; while the observation group received EEG bionic electrical stimulation at bilateral Tianzhu, Wangu (cheif electrodes) and Neiguan (auxiliary electrodes) in addition. They were treated for 30 days. They were assessed with the PVS score, and observed with transcranial Doppler ultrasound (TCD) and magnetic resonance spectroscopy (MRS) one day before and one day after treatment. Results The incidence of improvement was 86.67% in the observation group, more than 60.00% in the control group (P<0.05). The difference of blood flow velocity before and after treatment (ΔVm) of anterior-middle cerebral artery was more in the observation group than in the control group respectively (P< 0.001), as well as those of posterior cerebral-vertebral-basilar artery (P<0.01). The N-acetyl aspartic acid/creatine (NAA/Cr) increased more in the observation group than in the control group respectively (P<0.01), and the choline/creatine (Cho/Cr) decreased more (P<0.01), after treatment. Conclusion EEG bionic electrical stimulation can improve the cerebral circulation and metabolism in patients with PVS, which may associate with the wake promoting.

The control group re-ceived routine treatment, including basic management, hyperbaric oxygen therapy, awaking medicine, sensory stimulation, and so on;while the observation group received EEG bionic electrical stimulation at bilateral Tianzhu, Wangu (cheif electrodes) and Neiguan (auxiliary elec-trodes) in addition. They were treated for 30 days. They were assessed with the PVS score, and observed with transcranial Doppler ultra-sound (TCD) and magnetic resonance spectroscopy (MRS) one day before and one day after treatment. Results The incidence of improve-ment was 86.67%in the observation group, more than 60.00%in the control group (P<0.05).

RESUMO
@#Objective To observe the effects of repeated Botulinum toxin type A (BTX-A) injection on lower limb spasticity after stroke.Methods 180 cases with lower limb spasticity after stroke were divided into the treatment group (n=90) and the control group (n=90). The treatment group was treated with BTX-A injection twice in the spastic muscles at interval of 3~6 months, while both the treatment group and the control group accepted the rehabilitation based on the neurodevelopmental therapy. They were assessed with modified Ashworth Scale (MAS), Fugl-Meyer Lower Limb Assessment (FMAL), Berg Balance Scale (BBS), modified Barthel Index (MBI) before each injection, and 3 d, 7 d, 1 month, 3 months after each injection or the same time for the controls. Results There was significant difference in scores of MAS, FMAL, BBS, MBI for the treatment group among before and 3 d, 7 d, 1 month after each injection (P<0.05), but not significant between 2 injections (P<0.05). There was significant difference in scores of all the assessment between the treatment and control group at the same time (P<0.01). Conclusion Repeated intramuscular injection of BTX-A can reduce the spasticity of lower limb after stroke.
RESUMO
@#ObjectiveTo discuss the relationships among spastic paralysis and motor function, balance function and other clinical variables after stroke.MethodsAssessed the clinical spastic index of hemiplegic lower limbs with CSI scale, motor function with Fugl-Meyer Assessment, and balance function with Berg Equilibrium Scale, respectively. And then analyzed the relationship between clinical spasm index with motor function, balance function of the hemiplegic lower limbs with Pearson correlation analysis. Finally, ascertained which was the most important factor affecting the clinical spasm index of spastic lower limbs with stepwise regression analysis.ResultsThere is negative correlation between clinical spasm index with motor function and balance function, respectively. Tendon reflex, muscular tension and clonus are the deciding factors to motor function(P<0.05) and balance function(P<0.05) of the hemiplegic lower limbs.ConclusionThe clinical spasm index of hemiplegic limbs can affect the recovery of motor function and balance function significantly. So, assessing and improving the clinical spasm index of paralytic lower limbs can optimize the rehabilitation program to stroke patients.
