Term
decorticate vs decerebrate rigitidy, what is the difference
Definition
whether the lesion is above or below the red nucleus
Term
no tone =
Definition
flaccidity
Term
rate dependent resistance to PROM tone
Definition
spasticity
Term
what type of reflexes are present with spasticity
Definition
hyperreflexive
Term
type of reflexes seen with low tone
Definition
hyporeflexia
Term
hypotonia is seen where (2)
Definition
starting to come out of flaccidity, also seen with cerebellar lesions
Term
resistance ot passive stretch then gives way, decrease resistance
Definition
clasp knife reflex
Term
ratchet type resistance not rate dependent rigidty
Definition
cogwheel
Term
stiff resistance, may have limited ROM, not rate depedent rigitdy
Definition
lead pipe
Term
an increase in muscle tone with a marked velocity dependent increase when the muscle is passively stretch
Definition
spasticity
Term
causes for increased tone
Definition
changes in excitability of spinal interneurons, receptor hypersensitivity, formation of new synapses by sprouting
Term
New theory in spasticity is a result of the state of the muscle, why?
Definition
input from the mm spindle
Term
New theory of spasticity: muscle state: gilman's theory
Definition
centrla hypersensitivity to spindle inflow rather than a change in gamma motor neuron system activity
Term
New theory of spasticity: muscle state: hufschmidt
Definition
mm tone is due primarly to change in intrinsic mechanical properties of the spastic mm
Term
New theory of spasticity: muscle state: McComas theory
Definition
between 2-6 months number of functioning motor units is 50% in addition those motor units suriving had slower contraction times, longer latencies of conduction, and a decreased response to repetitive firing
Term
New theory of spasticity: muscle state: Powers theory
Definition
motor neuron resting membrane potential which is more depolarized than normal, as a result quick to discahrge and produce reflex activty
Term
Modified Ashworth Scale: 0
Definition
no increase in mm tone (normal or flaccid)
Term
Modified Ashworth Scale: 1
Definition
slight increase in mm tone, "catch" and relase with limb movement
Term
Modified Ashworth Scale: 1+
Definition
slight increase in mm tone "catch" when limb moved then decreased resistance through remainder of ROM
Term
Modified Ashworth Scale: 2
Definition
more marked increased in mm tone
Term
Modified Ashworth Scale: 3
Definition
considerable increase in mm tone
Term
Modified Ashworth Scale: 4
Definition
affected parts rigid in flexion or extension
Term
New Motor Assessment Scale: 1/6
Definition
flaccid, no resistance when body parts handled
Term
New Motor Assessment Scale: 2/6
Definition
some response felt as body parts are moved
Term
New Motor Assessment Scale: 3/6
Definition
variable, sometimes flaccid, sometimes good tone, sometimes hypertonic
Term
New Motor Assessment Scale: 4/6
Definition
consistently normal response
Term
New Motor Assessment Scale: 5/6
Definition
hypertonic 50% of the time
Term
New Motor Assessment Scale: 6/6
Definition
hypertonic at all times
