A NIHSS score of 6 or higher is one of the inclusion criteria for endovascular mechanical clot disruption.
Step-by-step explanation:
In the context of endovascular mechanical clot disruption, a National Institutes of Health Stroke Scale (NIHSS) score of 6 or higher is one of the inclusion criteria.

It assesses various neurological functions such as motor skills, language abilities, and visual fields.
