Increased muscular resistance felt by the examiner during quick joint movement, quickly fades.
Spasticity
Spasticity is indicative of UMN lesion involving what type of spinal tracts?
Cortical or pyramidal pathway lesions
Involuntary muscular resistance felt when moving a resting joint and persists through the joints entire ROM.
Rigidity
Rigidity is indicative of UMN lesion involving what spinal tract?
Extrapyramidal
Hypotonia (decreased muscle tone) is usually indicative of damage to 1 of what 2 areas?
- -LMN lesion
- -cerebellar disease
What is a loss of normal neurological function (reduction in muscle tone, reflexes, strength, etc.)?
