Brief Summary:

An exploratory clinical study on a Variable Speed and Sensing Treadmill system(VASST) for hemiparetic gait rehabilitation after stroke.

Building upon the positive results of VASST I conducted in 2012, VASST II will be an open label pilot trial of 11 subjects screened for eligibility by TTSH medical and rehabilitation team Study hypotheses : Training on VASST may result in a gain of +40% - 50% for distance walked and +10-20% of gait speed compared to baseline and response rate of 85% and serious adverse event rate of <10%.

  5. Functional ambulation category (FAC >/= 2) (subject needs at most minimal assistance to walk)

Exclusion Criteria:
