 Experimental Approach In this blinded randomized control trial funded by the Heart Stroke Foundation, 76 participants with stroke will be recruited from an inpatient rehabilitation unit. This number will provide enough power to detect a large effect size 0.83 with the primary outcome measure and accounting for a 20 drop-out rate. Individuals who are medically stable and who can sit for at least 20 minutes with or without trunk support but cannot stand independently for more than one minute will be eligible. These criteria will target our selection to those who need to work most on sitting balance. Participants will be randomized into experimental and control groups.
