Gait anaylysis Flashcards
Why perform gait analysis?
determine functional ability, eval for pt intervention, determine d/c plan, eval surgincal intervention, evaluate orthotic devices, research
What are the three essential requirement of Gait?
progression, stability, adatapiltiy
What is Progression of gait?
rhythmic pattern and ability to initiate and terminate movement
What is stability of gait?
maintain posture for upright, dynamic stability, and interact with forces of gravity and other forces.
What is adaptability of gait?
Meet the goals of the individual and meet the demands of the environment.
When are the two double limb support?
Loading response and pre-swing
When is heel off?
Terminal stance
When is shock absorption occuring?
loading response.
When is the end of weight acceptance?
Foot flat
When is the start of terminal stance?
heel off
How many % is the stance phase?
60
During loading response what is the Ankle, Quad, H/s, hip abductors/TFL, Erector spinae, and Glue max doing?
Ankle: ecc contracting for control of foot slap
Quad: ecc contraction for control of knee flexion
H/S: isometric contraction for control knee flexion
Hip abd/TFL: isometric contraction to prevent pelvic drop
ES: isometric contraction to control forward flexion and trunk stability
GMax: during IC and Midstance= concentric contraction to generate power
During Midstance what is the foot intrinsics, ankle, Quad, and hip abd doing?
Foot intrinsics: concentric to promote rigid structure from pro to supination
anke: PFers eccentric to control tibial advancement
Quad: concentric to initiate knee extension
Hip abd: isometric control pelvic drop
During terminal stance what is the foot intrinsics, ankle, hip abd, iliopsoas, and quad doing?
Foot intrinsics: isometric
ankle PF: concentric to control heel strike
HIp abd: isometric to concentric to elevate pelvis
Iliopsoas: eccentric for control hip exntension
Quad: inactive bc PRF and PFers maintian knee extension
During preswing what is the ankle, iliopsoas, rectus femoris, and ES doing?
Ankle PFers: concentric to provide propulsive push off
Iliopsoas: eccentric to concentric for limb advancement pull off
rectus femoris: isometric to limit knee flexion
ES: active *controversial
