Stroke survivors often face substantial and long-lasting problems with their arms. Both arms often decline together: When one arm is more severely affected by the stroke, the other becomes more difficult to use as well. Compared with a healthy person’s dominant hand, a stroke survivor may take up to three times longer to complete everyday tasks using their less-impaired arm.
This creates a frustrating reality. People with severe impairment in one arm must rely almost entirely on their other arm for daily activities, such as eating, dressing and household tasks. When that “good” arm works slowly or awkwardly, even simple activities become tiring and discouraging, and some people may begin to avoid them altogether.
