Collapsing Weakness

Collapsing Weakness

Collapsing weakness, or "give-way" weakness, suggesting intermittent voluntary effort, is often taken as a sign of functional weakness. Although sometimes labeled as "volitional weakness", it is not clear that such weakness is in any conscious sense willed, and it is therefore probably better to use a noncommittal term, such as "apparent weakness." Such collapsing weakness has also been recorded following acute brain lesions, such as stroke.
