Video: Strength testing' showing arms

Description: With an UMN lesion the fine, fractionated movements of the fingers and hand are lost. Distal extremity weakness is greater than proximal weakness. With greater effort to move the paretic hand, there is overflow activation of proximal muscles and even of the contralateral hand, which produces mirror or synkinetic movements.
