| Stage 1 | 
Muscles are in a flaccid state, no voluntary movement, tendon reflexes are weakened or absent | 
| Stage 2 | 
Muscle tone begins to increase, limb shows associated reactions, initial synergistic movements | 
| Stage 3 | 
Muscle spasticity reaches its peak, limb can initiate voluntary synergistic movements, accompanied by corresponding joint movements | 
| Stage 4 | 
Muscle spasticity begins to decrease, components of synergistic movements gradually reduce, partial isolated movements appear | 
| Stage 5 | 
Muscle spasticity significantly decreases, synergistic movement patterns mostly disappear, isolated movements are more complete | 
| Stage 6 | 
Coordinated movements are normal or near normal |
