Using a stratified random sampling procedure, the study participants will first be divided into homogenous subgroups with respect to: a) the ability to perform active finger extension and b) gender. Active finger extension has shown to be a simple and reliable early predictor of recovery of upper limb functioning in stroke patients. The patients in each subgroup will then be randomly assigned to either the continuous or the intermittent group. The therapists providing OT/PT training and the therapists performing assessments will be blinded to group allocation. The study participants will be blinded to our hypothesis on which type of suprasensory ESS is most effective.
