Flexor-hypertonia being the most common symptom of stroke, overcoming it by attaining wrist-extension can be judged as key function of recovery of stroke. We compared activation pattern of dominant versus non-dominant hand movements of wrist-extension of 6 healthy-subjects with 6 dominant and 6 non-dominant stroke using fMRI. Results in healthy-subjects show differences in activation-pattern of dominant and non-dominant hand. Stroke patient’s results shows ipsilesional activation-pattern with dominant-hemisphere stroke with activation in motor, sensory area and cerebellum as compared to no ipsilesional activation-pattern in non-dominant hemisphere stroke. These results might have further implication in structuring rehabilitation-protocol for different hemisphere stroke differently.
