Lecture 3: LE orthoses Flashcards
purposes of post op/rehab KOs
protect during healing
immobilize or restrict ROM
purpose of functional KOs
provide stability:
- ligamentous
- varus/valgus
- hyperextension
purpose of KOs for patellofemoral pain
improve patellar tracking
pain relief
purpose of off loading Kos for knee OA
reduced load (unicompartmental)
improved function
pain relief
KAFOs are appropriate for what pts
pts with:
- poor frontal plane knee control
- excessive knee recurvatum
- weakness of hip extensors
those with quad strength less than 3+/5 and/or impaired/absent proprioception
can be used for ambulation in clinic, home, and community
free motion knee joint
no limits in sagittal plane
restricts frontal and transverse plane motion
posterior offset knee joint
prevents hyperextension
assists with extension during stance
limited motion knee joint
restricted motion
can limit flexion and/or extension
locked knee joint
holds knee in one position
prevents all motion
stance control knee joint
free during swing
provides stability during stance
indications for hip orthoses
childhood skeletal disorders (i.e. congenital hip dysplasia or Legg-calve perthese disease)
post op to restrict movement and/or prevent dislocation (i.e. THA)
free motion hip joint
no limits in sagittal plane
restricts frontal and transverse
restricts dislocation
limited motion hip joint
restricted motion
can limit flexion an/or ext
locked hip joint
holds hip joint in one position
prevents all movement
abducted hip joint
aligned in abduction (legs calve perthes)
