Objective[edit | edit source]
The Composite Spasticity Index (CSI) is a tool designed to quantify the spasticity of limbs.[1]
Intended Population[edit | edit source]
It is intended for use in patients with stroke.[1]
Method of Use[edit | edit source]
The CSI has three components:[1]
- Tendon jerk
- Resistance to passive flexion
- Clonus
Tendon jerk[edit | edit source]
The biceps, triceps, patellar, or Achilles tendon could be chosen for testing. Ensure sufficient force is used while tapping the tendon so as to elicit a 'maximal' reflex jerk and compare the result with the unaffected limb.[1]
| 0 | No response |
| 1 | Normal response |
| 2 | Mildly hyperactive response |
| 3 | Moderately hyperactive response |
| 4 | Maximally hyperactive response |
Resistance to passive stretch[edit | edit source]
The resistance felt during this test allows the examiner to evaluate the hyperactivity of the tonic stretch reflex. The stretch must be performed at moderate speed (>100 degrees per second).[1]
Note the presence of contractures and/or a clasp-knife response before examination.[1]
| 0 | No resistance (hypotonic) |
| 2 | Normal resistance |
| 4 | Mildly increased resistance |
| 6 | Moderately increased resistance |
| 8 | Maximally increased resistance |
This item is doubly weighted due to its close relation to hypertonus.[1]
Clonus[edit | edit source]
On rapid flexion of the wrist or ankle, the examiner notes the number of beats of clonus (if present).[1]
| 1 | Clonus not elicited |
| 2 | 1-3 beats of clonus elicited |
| 3 | 3-10 beats of clonus elicited |
| 4 | Sustained clonus |
Interpretation[edit | edit source]
The composite score (sum of scores from each component) is used to ascertain the severity of spasticity.[1]
| 0-9 | Mild |
| 10-12 | Moderate |
| 13-16 | Severe |
Evidence[edit | edit source]
Reliability[edit | edit source]
The CSI has excellent test-retest reliability (r = 0.87).[2]
Validity[edit | edit source]
The CSI is valid for the examination of spasticity in elbow flexors and extensors.[3]
Responsiveness[edit | edit source]
The responsiveness of the CSI has not been studied.
