In the first study, we propose 20 subjects who have sustained their first ever haemorrhagic or ischaemic subcortical stroke with lower limb impairment more than 9 months prior to study enrollment. Subjects will be recruited from the existing patients on the study physician's cohort of patients and from referrals from attending physicians. During the initial screening visit, it will be ascertained that subject fulfills criteria for participation and informed consent will be obtained by study staff. Subjects will be fully briefed in detail regarding the experimental procedure, risk and benefits involved and their responsibilities during the study.
