What is onset of asymmetric quadriparesis disease?

Meaning? Simple---: Asymmetric= Not BOTH sides at the same time. First one side, then, the other then, a leg followed by some arm or possibly the other leg....ASYMMETRIC. quadriparesis- Weakness in a limb (usually taken to mean, motor movements are weakened). So essentially it's describing onset of a disease causing limb weakness which starts in a fashion that does not include BOTH sides of the person at once.
