  1. Phases of the Gait Cycle
    Stance = 60% (Closed Chain)

    Swing = 40% (Open Chain)
  2. Components of Stance Phase
    Traditional / Ranchos Los Amigos

    • Heel Strike / Initial Contact
    • Foot Flat   /  Loading Response
    • Midstance /  Midstance
    • Heel Off   /  Terminal Stance
    • Toe Off    /  Preswing
  3. Components of Swing Phase
    Traditional / Ranchos Los Amigos

    • Acceleration  / Initial Swing
    • Midswing      / Midswing
    • Deceleration / Terminal Swing
  4. Gait Cycle Measurements
    • Step Length
    • Toe off to heel strike of same foot
    • average = 15"

    • Stride Length
    • heel strike to heel strike of same foot
    • average = 30-32"

    • Base of Support
    • Width from middle of each heel
    • average = 2-4"

    • Toe Out
    • Angle of lines:
    • 1st line = measured from middle of heel
    • 2nd line = middle of heel to 2nd toe
    • average = 7 deg
    • (anteverted = toes inward (pigeon toed))
    • (retroverted = toes outward)

    • Cadance
    • Steps per minute
    • average = 90-120 steps/min
  5. Deviations with Gait Cycle
    Foot Slap during heel strike/initial contact & foot flap/loading response = anterior tib (ecc)

    • Knee Buckle during heel strike/initial contact & foot flat/loading response = quads (ecc)
    • compensation = lean forward

    • Leaning forward @ hip during heel strike/initial contact & foot flat/loading response = glut max (ecc)
    • compensation = increase lordosis, lean back, glut max lurch

    • Hip drop during midstance = glut med (iso) (opp glut med of hip drop)
    • compensation = trunk leaning toward affected side

    • Flat foot during heel off = plantar flexors (con)
    • compensations = shorter swing phase

    • Foot drop during acceleration/initial swing = ant tib (con)
    • compensations = hip hiking, circumducation, high steppage, vaulting
