Gait Flashcards
trunk lean
- can be multi-directional
- contralateral side lean to allow for clearance of swing leg
cicumduction
Hip abd and flex to clear the foot during gait
Vaulting Gait
supporting leg is stance phase goes up on toes to create ground clearance of the swing leg
What is the function of the cerebellum in gait control
smoothes and coordinates movement
What is the function of the motor cortex
is for goal directed and skilled walking
What is CPG
Central pattern generator
– guides rhythm and smoothness
What does the spinal cord control in the gait
Rhythm
What does brain stem control in gait
Equilibrium
balance
initiation
60% of gait cycle in which phase
Stance phase
40% of gait is in which phase
Swing phase
20-25 % of gait phase is spent
Double Contact
stance Phase consist of what 3 segments
heel contact
mid-stance
terminal stance
Swing Phase consist of what 3 segments
Toe off
mid swing
terminal swing
Muscles activated in during heel strike of stance Phase
hip extensor dorsi flexors knee extensors hamstrings tib ant
Muscle activated during mid stance
Hip abd to prevent collapse in fronal plane
plantar flexors eccentrically contracting
quads fire to anticipate of accepting wieight
When is potential energy highest
Mid stance
Normal walking requires what 3 things
locomotion
postural control
Adaptation
When is kinetic energy highest
at heel contact -end of swing phase
Antalgic Gait
painful gait
when someone limps
longer stance phase
longer siwng phase
What muscles are activated during toes off in the swing phase
tib ant
hip flexors
passive knee flexion
What muscles are activated during terminal stance
-plantar flexors
glut max
What muscle are activated during terminal swing
Glut max- eccentric contraction
Ham strings- prevents hyperextension
Tib Ant
quad get ready to except weight
Trendelenburg gait
-causes form glut med/min weakness
opposite hip drops
