Gait Kinematics Flashcards
why do women walk with more frontal plane movement during gait
bigger Q-angle
normal motion for pelvis in sagittal plane
2-4 degrees
pelvic tilting will _________ with increased speed of ambulation
increase
what happens to gait with tight hip flexors
exaggerated anterior pelvic tilt in 2nd half of stance phase (30-60%)
-increased lumbar lordosis
hip flexion degrees on heel strike
30 degrees
degrees of extension in toe off
10 degrees
hip extension contracture causes…
early swing initiation
mid-stance degrees of hip flexion
0-5 degrees
terminal stance flexion degrees
10-20 degrees
terminal swing degrees of flexion
30 degrees
what happens when there is a knee flexion contracture or inability to achieve terminal knee extension
opposite knee and hip will have to flex more
what happens to the knee with lack of hip flexion
more knee flexion for toe clearance
what happens to the knee with lack of dorsiflexion
increased knee flexion for toe clearance
how many degrees of dorsiflexion is needed for midstance
10 degrees
how many degrees of plantarflexion is needed for toe off
20 degrees
limited PF of ankle results in…
decreased push off and shorter step length
lack of ankle DR results in…
increased pronation, bouncing gait, premature heel off
what position is the first metatarsophalangeal joint at during heel strike and most of stance phase
slight extension to neutral
for heel off and toe off, how many degrees of extension does the toe do
45 degrees
what does lack of toe extension lead to
over-pronation and/or more toe-out
increased stress on the medial structures of foot/ankle
