^a Patients were categorized as “red,” “amber,” or “green” based on their initial assessments. Patients categorized as red either had no impairment or no active movement in their upper limb and, therefore, were not suitable for exercises. Patients categorized as amber had upper limb impairment and active movement but would require assistance or supervision with self-directed exercise due to cognition problems or limited safety awareness, for example. Patients categorized as green were those who had upper limb impairment and active movement and would be able to safely complete self-directed exercises independently.
