The long-term objective of CO-OP KT is to optimize functional outcomes for individuals with stroke and cognitive impairments. Three specific research questions have been posed, one of which is the focus of this registration. That sub study relates to patient outcomes following the CO-OP KT training initiative and it will be addressed using a non-randomized design with historical controls. Patient participants who enroll in the project prior to implementing the CO-OP KT training will belong to the historical control group. Patient participants who enroll in the project after the CO-OP KT training will belong to the CO-OP KT Exposure group.
