-
Asthenia
Generalized weakness, secondary to cerebellar dysfunction
-
Ataxia
Inability to perform coordinated movements
-
Athetosis
- Involuntary sustained postures
- Peripheral movements without central stability
-
Chorea
Sudden, random, involuntary movement
-
Clasp knife response
Hypertonicity and resistance in initiation of range that decreases throughout range
-
Clonus
- UMN lesion
- Involuntary alternating spasmodic contraction of a muscle due to a quick stretch
-
Cogwheel rigidity
- Resistance to movement that has a phasic quality
- Ex: PD
-
Dysmetria
Can’t control the range of a movement and the force of the muscular activity
-
Dystonia
Related to athetosis but is demonstrates larger axial muscle involvement than appendicular muscles
-
Fasciculations
Muscular twitch caused by random discharge of a LMN and its muscle fibers
-
Hemiballism
Involuntary, violent movement of a large body part
-
Lead pipe rigidity
- Uniform, constant resistance to ROM
- Associated with basal ganglia lesion
-
Rigidity
Severe Hypertonicity where a sustained muscle contraction does not allow any movement of a specified jt
-
Tremor
Involuntary, rhythmic, oscillary movement secondary to basal ganglia lesion
