Phase II: With ii lt iiWith minimal training, infrequent or novice users of the NIHSS-PE can get reliablethe NIHSSPE can get reliable scores of Stroke We hope that this user-friendly version will make the NIHSS more accessible to rural and ll itllifid tsmall sites, allowing more confident assessment of Stroke Providence medical FoundationThe Providence medical FoundationThe Providence Brain Institute NIHSS T i iNIHSS T i iNIHSS TrainingNIHSS Training1a.
