Cog-wheel rigidity
Motor dysfunction secondary to lesion of basal ganglia
- muscles respond in jerky motion when force is applied during flexion of a joint
- common PD symptom
Clasp-knife rigidity
Reflexive abnormal motor response due to cortical lesion
- spastic muscle suddenly releases tension & gives way in response to passive stretch
Lead pipe rigidity
Motor dysfunction secondary to a lesion of basal ganglia
- slow PROM, constant resistance is felt throughout
- common PD symptom
Clonus
Reflexive abnormal motor movements in response to tendon stretch (as in reflex testing)
- indicative of a cortical lesion
- series of involuntary rhythmic contraction & relaxation of the muscle
