What are the 2 types of hypertonia (inc. m. tone)
Spasticity and Rigidity
Sometimes referred to as “gooseneck” rigidity, involuntary resistance felt when moving a resting joint through its entire motion is usually consistent with what lesion
Extrapyramidal pathways/Upper Motor Neuron Lesion
Sometimes referred to as “clasped knife”, tension at first followed by a dec. in tension as joint is opened, spasticity usually indicates what lesion
Cortical or pyramidal pathway/Upper Motor Neuron Lesion
What does hypotonia usually indicate
Neurological damage at the level of the reflex arc/Lower Motor Neuron Lesion
What may cause diffuse hypotonia
Cerebellar disease
What is the unique finding in Neural Shock
Suddenly occurring and severe UMNL, cause CNS findings
What can all neurological signs be divided into
Deficit and Release phenomena
Exaggerations or perversions of normal neurologic function and due to loss of cortical inhibition. Hypers and pathologic reflexes describe what phenomena
Release phenomena
Loss of normal neurological function, dec. in m. tone, reflexes, strength, volume, and LMNL describe what phenomena
Deficit phenomena
