Effect of Central Versus Peripheral Stimulation on Hand Function in Stroke Patients, GEHAN M. AHMED, EBTESAM M. FAHMY and RANIA M. TAWFIK
Abstract
Background and Purpose: More than 60% of stroke survivors suffer from persistent neurological deficits that impair activities of daily living. Electrical stimulation is shown to be effective in enhancing the upper extremity functional recovery in stroke patients. The goal of this study was to compare between the effect of central and peripheral stimu-lation on hand function in these patients.
Patients and Methods: This study was conducted on forty five stroke patients from both sexes, their ages ranged from 45 to 60 years. The patients were divided into three equal groups. The study group (I) received anodal transcranial direct current stimulation in addition to the selected physical therapy program. The study group (II) received neuromuscular elec-trical stimulation in addition to the selected physical therapy program and the control group (III) received the selected physical therapy program only. Hand function was measured using Jebsen Taylor Hand Function Test (JTT).
Results: There was a statistically significant decrease of the mean values of JTT test score in group I and group II post treatment while the changes in group III were not significant. There was a significant decrease in the mean value of JTT test in group I compared with group II and group III.
Conclusion: Both Central and peripheral stimulation are effective modalities in improvement of hand function post stroke while the central stimulation is more effective than the peripheral one.
