Nurick (Ambulatory Function) Grade
Please visit this website for more information about the instrument: Nurick (Ambulatory Function) Grade
Supplemental – Highly Recommended: Chiari I Malformation (CM)
Short Description of Instrument
Purpose: Nurick's classification system is aimed at patients presenting with myelopathy on the basis of gait abnormalities. This grading scale also assess ambulatory functions, and includes a lower limb component.
Comments/Special Instructions
The Nurick Classification System was developed to assess the importance of ischaemia of the spinal cord caused by spondylosis (Nurick, 1972).
Scoring: The scale works from 0–5, with higher scores indicating more severe injuries. The scores are as follows:
Grade 0: Signs or symptoms of root involvement but without evidence of spinal cord disease
Grade 1: Signs of spinal cord disease but no difficulty in walking
Grade 2: Slight difficulty in walking which did not prevent full-time employment
Grade 3: Difficulty in walking which prevented full-time employment or the ability to do all housework, but which was not so severe as to require someone else's help to walk
Grade 4: Able to walk only with someone else's help or with the aid of a frame
            Grade 5: Chair bound or bed ridden
A very well established functional disability scale, widely used for decades, and well validated.
