Nurick and mJOA Myelopathy Grading Scales

Grade cervical spondylotic myelopathy (CSM) severity using Nurick grade (0-5) and modified Japanese Orthopaedic Association (mJOA) score (0-18). mJOA grades functional impairment in upper limb, lower limb, bladder, and sensation. Guides surgical timing.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Grade cervical spondylotic myelopathy (CSM) severity using Nurick grade (0-5) and modified Japanese Orthopaedic Association (mJOA) score (0-18). mJOA grades functional impairment in upper limb, lower limb, bladder, and sensation. Guides surgical timing

Each component has a specific meaning:

  • Nurick grade — The nurick grade recorded for the scenario being assessed.

Note: Interpret the nurick mjoa myelopathy result against the thresholds and context described above.

How to Use

Enter the Nurick grade for the scenario you are assessing. Grade cervical spondylotic myelopathy (CSM) severity using Nurick grade (0-5) and modified Japanese Orthopaedic Association (mJOA) score (0-18). mJOA grades functional impairment in upper limb, lower limb, bladder, and sensation. Guides surgical timing. Use the nurick mjoa myelopathy result to inform your calculation.
