inability to perform coordinated movements
Athetosis
involuntary low amplitude movements with instability of posture (slow), seen in CP
Bradykinesia
slow movements
Chorea
sudden, random movements, seen in Huntingtons
Clasp-knife response
hypertonic resistance at beginning of range that lessens with movement through range
Clonus
spasmodic contraction precipitated by quick stretch
Cogwheel rigidity
resistance to movement when bending limb but in repeated, cogwheel-like jerks
Dysdiadochokinesia
inability to perform rapid alternating movements
Dysmetria
inability to control ROM
Dystonia
involuntary muscle contractions (sustained, repetitive, can be painful), seen in PD/CP/encephalitis
