Outcomes
Primary Outcome Measures
Investigation of Neurological Deficit by National Institute of Health Scale Score (NIHSS)
The National Institutes of Health Stroke Scale, or NIH Stroke Scale (NIHSS) is a tool used by healthcare providers to objectively quantify the impairment caused by a stroke. The NIHSS is composed of 11 items, each of which scores a specific ability between a 0 and 4. For each item, a score of 0 typically indicates normal function in that specific ability, while a higher score is indicative of some level of impairment. The individual scores from each item are summed in order to calculate a patient's total NIHSS score. The maximum possible score is 42, with the minimum score being a 0. Higher score is indicative of some level of impairment in neurological function.
Investigation of Disability by Modified Rankin Scale (mRS)
The modified Rankin Scale (mRS) is a commonly used scale for measuring the degree of disability or dependence in the daily activities of people who have suffered a stroke or other causes of neurological disability.
The scale runs from 0-6, running from perfect health without symptoms to death.
0 - No symptoms.
- No significant disability. Able to carry out all usual activities, despite some symptoms.
- Slight disability. Able to look after own affairs without assistance, but unable to carry out all previous activities.
- Moderate disability. Requires some help, but able to walk unassisted.
- Moderately severe disability. Unable to attend to own bodily needs without assistance, and unable to walk unassisted.
- Severe disability. Requires constant nursing care and attention, bedridden, incontinent.
- Dead.
