Kinematic analysis - common gait deviations

ANKLE JOINT

Excessive Ankle Plantar Flexion- clinically described as Equinnus gait , commonly seen in cp

A) Stance Phase

1. Primary causes-Plantar flexors spasticity, contracture

2. ubstitution for –weak quads.

Ankle/forefoot pain

3.Consequences-dimished shock absorption-by limiting knee flexion in LR

-dec. forward progression of tibia over ankle

B) Swing phase

1.Primary cause- weakness/impaired selective control of DF

-PF spasticity/contracture

2. Consequences- interferes with foot clearance, foot positioning for IC

-results in toe-drag at mid-swing

-danger of tripping- can be averted by inc knee & hip flexion during swing if

proprioception is intact

Characterized by moderate reduction in gait velocity, inability to run, MT pain( due to chronic overuse of soft tissues), flat-foot posture

Where toe clearance is achieved by * circumduction

*non stance hip hiking

*vaulting at mid stance
