Motor Outcome of Stroke Patients with Low Dose Levodopa Therapy.

Stroke is one of the leading cause of disability worldwide. Motor function deficits due to stroke contribute to overall low quality of life. The objective was of this study is to observe functional motor outcome after stroke with low dose Levodopa therapy. This prospective follow up study was carried out in the Department of Neurology, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from July 2014 to June 2016 to see the effect of low dose of Levodopa (110mg) on motor outcome after stoke disability. Motor deficit was measured by Medical Research Council (MRC) grading and Rivermead Mobility Index (RMI) score. Two groups were selected by simple random method, consisted of both ischemic and hemorrhagic stroke. All the patients of both the groups were suffering from at least some post stroke motor disability and attended full course of physiotherapy. The group (L) received 110mg Levodopa with physiotherapy. On the other hand (NL) group received only physiotherapy. They were all followed up for four times within two months of time and were assessed for recovery of motor function. Mean age was 59.03±11.56 years in Levodopa (L) group and 57.10±12.41 years in the Non Levodopa (NL) group; Males were predominant in both groups. Ninety three (77.50%) cases had ischemic stroke and 27(22.50%) cases had hemorrhagic stroke. Most common risk factors were hypertension and smoking. No known risk factor was detected in 8 (6.67%) patients. Single or multiple risk factors were confirmed in 112 patients (93.33%). MRC score was significantly higher both in affected upper and lower limb in Levodopa group comparing non Levodopa group at 4th visit. RMI score was also significantly higher in Levodopa group comparing non Levodopa group at 4th visit. The Levodopa (L) group showed better recovery pattern than Non Levodopa (NL) group. It can be concluded that motor recovery was better with administration of a single low dose of Levodopa in combination with physiotherapy. Motor outcome was significantly higher in levodopa group than non-levodopa group.
