biomechanical limitations Flashcards
(39 cards)
biomechanical limitation
resistance from shortening , stiffness
biomechanical limitation from
abnormal positioning/movement prolonged immobilization impaired mm function infection swelling ossification
mm stiffness due to
passive stiffness
active stiffness
neurally mediated stiffness
increased mm stiffness from
changes in
mm length
mm thixotropy
connective tissue
changes in mm fibers
how mm length impacts stiffness
less extensibility makes more stiff,
mm thixotropy
connective tissue gets solid state
connective tissue impacts stiffness
scar tissue
changes in mm fibers impacts mm stiffness
size, fatigibuality, alignment
neurally mediated stiffness
spinal reflexes aren’t modulated by nervous system
PNS you see UMN or LMN signs
LMN
LMN signs
hypotonia
hyporeflexia
flacid
paralysis
UMN signs
hypertonia, hyperreflexia, spasticity
paralysis
__ results in decreased neural mediated stiffness
PNS
__ results in increased neural mediated stiffness
CNS
T/F not possible in mm innervated by damaged peripheral nerve to have increased neural stiffness
true
T/F CNS pathology can result in decreased neural mediated stiffness too
T
why CNS can be decreased neural mediated stiffness too
hypotonia early after injury (spinal shock)
what can cause joint limiation
client posture
alignment
speed of movement (spasticity)
heterotrophic ossification treatment consideratsion
same as for other biotech limitations
what can you not do for HO
no forced stretch
just acitve/ pass ROM
no casting / immbolization
what do for HO
functional activity
cardio
lease with MD
HO
bone forming inside soft tissue
clinical indicators of HO
sudden / dramatic decrease ROM
feel a bony block
confirmed on X-ray
what can HO be confused with
DVT, infection, trauma
