Brief summary

Stroke is the third common cause of adult disability in dveloped countries. Early identification of the potential for motor recovery is important to avoid 'learned disuse' and to initiate appropriate therapy with achievable goals. The current cohort study focuses on those patients with SAFE \<8 and using motor evoked potentials (MEPs) to improve on prognostication of upper limb motor recovery among subacute stroke patients in a local stroke population.
