- Increased muscle tone
- Overactive reflexes
- Spasmodic involuntary movements or clonus
- Decrease in the functioning and delay in the motor development
Classification of Spasticity
Spasticity is frequently classified by its presentation and divided into:
Spasticity Grading System
Modified Ashworth Scale
0 No increase in muscle tone.
1 Slight increase in muscle tone (catch and then release)
1+ Slight increase in muscle tone (catch which is followed by minimal resistance throughout the range of movement)
2 A more marked increase in muscle tone. (Resistance throughout most of the range of movement, but affected part can be easily moved)
3 Considerable increase in muscle tone, passive movement difficult.
4 Affected part(s) rigid in flexion or extension.
