|Stage 1||Flaccidity; no movements of the limbs can be initiated|
Spasticity begins to develop; the basic limb synergies or some of their components may be present|
Little or no active finger flexion can be performed.
Spasticity is marked; the basic limb synergies are performed voluntarily|
Mass grasp; hook grasp with no release; no voluntary finger extension
Spasticity begins to decrease; some movement combinations that deviated the synergies become available|
Small-range semi-voluntary finger extension
Spasticity is diminishing. More difficult movement combinations can be performed|
Voluntary mass extension of fingers
No spasticity; isolated joint movements can be performed normally|
Voluntary extension of fingers.
