Gait Cycle - Coggle Diagram

- - - - Knee extends - concentric contraction of sartorius/quads
      - Popliteal muscle to stabilise
      - Gastrocs
    - - Flexed before extending
    - - ACL, PCL, LCL, MCL - prevent excessive sliding/rotation
  - - - intrinsic muscles of foot
      - Subtalar supinators: Tib ant., gastrocs, plantar fascia
      - Plantar flexors eccentrically: closed chain dorsiflexion
    - - Supination
      - From plantar flexion into dorsiflexion (5-10º)
      - Talocrural joint adapts to surface
    - - Causes supination
- - - - Hip
        
        10-15° extension
      - Knee
        
        4° flexion
      - Ankle
        
        15° dorsiflexion moving towards plantarflexion
        supination
    - - Iliopsoas – Concentric
      - Gluteus Medius – Eccentric
      - Calf muscles (Gastroc) – Concentric
      - Plantar flexors - concentrically to prepare for push off
  - - - Hip
        
        Moving towards 10°of extension
      - Knee
        
        Moving from near full extension to 40°flexion
      - Ankle
        
        20° plantarflexion
        Supination
    - - Iliopsoas - concentrically
      - Adductor Magnus working eccentrically to control/ stabilise pelvis
      - Quadriceps contracting eccentrically
      - Plantar flexor muscles (calf muscles) – concentrically (at peak activity but becoming
        inactive as foot leaves ground)
- - - - Hip- 30 degrees flexion
      - Knee- 50/60 degrees flexion
      - Ankle- Max dorsiflexion
    - - Hip- Concentric Iliopsoas and Rec. Fem
      - Knee- Little muscle activation, acts as a pendulum from momentum generated at the hip
      - Ankle- Tib. Ant. Concentrically
  - - - Hip
        Begins to extend back towards neutral
      - Knee- Moves into Extension (-5/10 degrees)
      - Ankle- Max Dorsiflexion
    - - Hip- Eccentric Glute Max and Hamstrings
      - Knee- Eccentric Hamstrings
      - Ankle- Isometric Tibialis Anterior
