You are working with a patient status post stroke. When asked to actively raise the paretic arm or reach for objects, the patient is able to perform approximately 30 degrees of shoulder flexion before the flexor synergy pattern emerges. There is also no dissociation of the scapula and humerus with active movements of the paretic arm. Which of the following activities would be the most appropriate INITIAL intervention to facilitate fractionation of movement and functional reaching out of abnormal flexor synergistic pattern based on motor learning principles?
