common deviations Flashcards
during the foot slap phase the forefoot slaps the floor at initial contact. what is the possible cause?
flaccid, weak or atrophied dorsiflexors
during what stage of gait would you see the forefoot slap the floor?
initial contact
during what stage of gait does the toe first phase occur?
initial contact
what could be a possible cause of a toe first phase during initial contact?
Leg length discrepancy; contracted heel cord; plantarflexion contraction; spasticity of plantarflexors; flaccidity of dorsiflexors; painful heel.
what deviation happens in initial contact and is caracterized by the entire foot contacting the floor at heel strike?
foot flat phase
what are the possible causes of foot flat deviation?
Excessive fixed dorsiflexion; flaccid or weak dorsiflexors; neonatal/proprioceptive walking
What deviation occurs when the tibia does not advance to neutral from 10 degrees plantarflexion.
excessive positional plantarflexion
what are the possible causes of excessive positional plantarflexion
No eccentric contraction of plantarflexors; could be due to flaccidity/ weakness in plantarflexors; surgical overrealease, rupture, or contracture of Achilles tendon.
during what phase of gait does excessive positional plantarflexion occur?
midstance
what is it called if the heel DOES NOT contact ground in midstance
heel lift in midstance
what could cause heel lift in midstance?
Spasticity of plantarflexors
in what stage of gait does excessive positional dorsiflexion occur?
midstance
what is it called when the tibia advances too rapidly over foot, creating a greater than normal amount of dorsiflexion
Excessive positional dorsiflexion
what are the possible causes of excessive positional dorsiflexion?
Inability of plantarflexors to control tibial advance; knee flexion or hip flexion contractures
what is the deviation called when there is an insufficient transfer of weight from lateral heel to medial forefoot
no foll off
during what stage of gait does the no roll off deviation occur?
push-off stage
what are possible causes of the no roll off deviation?
mechanical fixation of ankle and foot. Flaccidity or inhibition of plantarflexors, inverters, and toe flexors. Rigidity/cocontraction of plantarflexors and dorsiflexors. Pain in forefoot
____________ deviation is described as insufficient dorsiflexion (and toe extension) so that forefoot and toes do not clear floor
toe drag
during what stage of gait does toe drag occur?
swing
what are possible causes of toe drag deviation?
Flaccidity or weakness of dorsiflexors and toe extensor. Spasticity of plantarflexors. Inadequate knee or hip flexion
during what stage of gait does excessive knee flexion occur?
initial contact (heel stike)
what deviation is described as knee flexes or buckles rather than extends as foot contacts ground?
excessive knee flexion
what are the possible causes of excessive knee flexion?
painful knee; spasticity of knee flexors or weak or flaccid quadriceps. short leg on contra lateral
what stages of gait does knee hyperextention occur?
foot flat and midstance
