Unstable Gait Flashcards
Stability Kinematics
Loading Response
Hip Maintain 20 F: wt bear stabil
Trunk Neutral
Stability Kinematics
Mid Stance
Knee 20F-0: prog COM over BOS; single stance stabil
Hip 20F-0: prog COM over BOS; single stance stabil
Stability Kinematics
Frontal Plane LR
Foot Pronate, 4-6 deg rearfoot eversion: shock absorb; stance stabil (more floor contact)
Stability Kinematics
Frontal Plane LR-Mid
Hip/Pelvs Neut to 3/5 add
Trunk SideBend 3/5
Weight bearing stabil via abductors
Stability Kinematics
Frontal Plane Term Stance
Hip/Pelv Neutral
Trunk Neutral
Global Observations of Instability
Trunk movement
Variable step length
Variable foot placement
Comps for Instability
Wide BOS and Slow velocity (makes swing phase more active because decrease moment)
Increased double limb support
Reliance on vision
Increased frontal plane motion (less catch)
Heavy reliance on assistive device
