| Grade | Muscle function |
|---|---|
| 0 | No muscle contraction |
| 1 | Muscle flickers |
| 2 | Full range of motion with gravity eliminated |
| 3 | Full range of motion against gravity |
| 4 | Full range of motion against resistance |
| 5 | Normal strength |
The American Spinal Injury Association (ASIA), formed in 1973,
The exam is based on neurological responses, touch and pinprick sensations tested in each dermatome, and strength of the muscles that control key motions on both sides of the body.[7] Muscle strength is scored on a scale of 0–5 according to the adjacent table, and sensation is graded on a scale of 0–2: 0 is no sensation, 1 is altered or decreased sensation, and 2 is full sensation.[8] Each side of the body is graded independently.[8] When an area is not available (e.g. because of an amputation or cast), it is recorded as "NT", "not testable".[3] The ISNCSCI exam is used for determining the neurological level of injury (the lowest area of full, uninterrupted sensation and function).[3]
The completeness or incompleteness of the injury is measured by the ASIA Impairment Scale (AIS).
| Grade | Description |
|---|---|
| A | Complete injury. No motor or sensory function is preserved in the sacral segments S4 or S5. |
| B | Sensory incomplete. Sensory but not motor function is preserved below the level of injury, including the sacral segments. |
| C | Motor incomplete. Motor function is preserved below the level of injury, and more than half of muscles tested below the level of injury have a muscle grade less than 3 (see muscle strength scores table). |
| D | Motor incomplete. Motor function is preserved below the level of injury and at least half of the key muscles below the neurological level have a muscle grade of 3 or more. |
| E | Normal. No motor or sensory deficits, but deficits existed in the past. |
