A 22-year-old male asked:

kernicterus causes spasticity? why is it sis basal ganglia considered in pyramidal tract? why not causing rigidity instead like parkinsons?

Spasticity: Basal ganglia and substantia nigra are different structures. Injuring the basal ganglia, such as by stroke, may cause spasticity. Injuring the substantia nigra may cause parkinsons symptoms, such as tremor and rigidity. Rigidity and spasticity are not the same, as you recognize. These two different structures of the brain modulate movement differently, that is why the symptoms are different.

4 major ones: Treating spinal cord injury is more about minimizing the amount of damage at the time of injury: Methylprednisolone may have some benefit, but studies are inconclusive. As for spasticity, four drugs are standard of care: baclofen, diazepam, tizanidine, & dantrolene. Each has benefits and drawbacks; they all come in generic. Some may require more than one drug, or the use of a drug pump device.

It doesn't.: It's just more noticeable since walking is a much more complex and dangerous activity.
