Brunnstrom (1966, 1970) and Sawner (1992) also described the process of recovery following stroke-induced hemiplegia. The process was divided into a number of stages:


Brunnstrom (1966, 1970) described the process of recovery following stroke-induced hemiplegia. The process was divided into a number of stages:
Synergy. A whole series of muscles are recruited when just a few are needed. Trying to reach forward, The arm wings outward, the shoulder lifts, the wrist curls down. Lots of this is from spasticity

1. Flaccidity (immediately after the onset)
No "voluntary" movements on the affected side can be initiated
2. Spasticity appears
Basic synergy patterns appear
Minimal voluntary movements may be present
3. Patient gains voluntary control over synergies
Increase in spasticity
4. Some movement patterns out of synergy are mastered (synergy patterns still predominate)
Decrease in spasticity
5. If progress continues, more complex movement combinations are learned as the basic synergies lose their dominance over motor acts
Further decrease in spasticity
6. Disappearance of spasticity
Individual joint movements become possible and coordination approaches normal
7. Normal function is restored

Where are the answers to this?
A lot of problems here are because spasticity is subjectively measured, if you can't properly measure something you can't figure out how to fix it.
