- в отличие от реальной/клинической

Perceived Weakness Vs. Clinical Weakness. "To put it simply, the difference between perceived and true clinical weakness is that if you have perceived weakness, then it is felt by you only. However, if you are asked to do a task requiring you to use the weak arm (for example) and you put your mind and effort into it, you will be able to perform the task. "
