Flaccid dysarthria involvement?
in one or more cranial or spinal nerves
at what level are the problems located for flaccid dysarthria?
final common pathway
what type of lesions would result in flaccid dysarthria?
lesions to LMN that innervate respiratory musculature, or CNs that innervate speech musculature
what is the most prominent feature of flaccid dysarthria?
muscle weakness
what are the hallmarks of flaccid dysarthria?
- hypernasality
- nasal air emission
- audible inspiration or stridor on inhalation
- often speaks in short phrases
clinical characteristic of flaccid paralysis
FCP damage
reflexive, automatic, and voluntary movements are all affected
if all LMN is lost, what is the result?
paralysis
if some of LMN is lost, what is the result?
paresis
what are fasciculations?
muscle twitches– a small, involuntary muscle contraction and relaxation
what is neuromuscular junction?
rapid weakening of muscle with use, followed by recovery with rest

How do you plan for intervention?
- ID the deficit areas
- work on impairment while also integrating compensatory strategies
- SLOP
