tone Flashcards
mm tone
the resistance to stretch in resting mm
how is mm tone modified
nervous system conscious and unconscious control
___ dampens down hyper excitable spinal reflexes
descending corticospinal influence
T/F humans have range of mm tone
t
longstanding flacidity PNS or CNS
PNS LMN
rigidity vs spasticity
rigiity is velocity INDEPDENT
spasticity is DEPDEND
rigidity features
bidirectional resistican to stretch
velocity independent
righty is hyperreflexia always evident
not always
decerebrate rigidity characterized
both U/LE in Ext
decorticate rigidity characterized
UE in flex
LE in ext
spasticity
velocity dependent inc in tonic stretch reflex
exaggerated tendon jerks
hyperexcitabilty
UMN
can spasticity impact pts alertness
yes
hyperreflexia UMN or LMN
UMN
hyporeflexia UMN or LMN
LMN
when is stretch reflex not normal
grade 0, 4+ and 5+
