Progression of gait over the supporting foot requires __ rockers. What are they?
3
- First Rocker (Heel)-Motion of the foot from a DF to PF position during LR to achieve foot flat.
- Second Rocker (Ankle)-Closed chain advancement of the tibia into a DF position over a fixed foot during MSt.
- Third Rocker (Forefoot)-Begins when COP is over the mets and heel lift occurs in TSt/PSw.

Stance Phase: IC Hip -Position? -Major muscles? Knee -Position? -Major muscles? Ankle -Position? -Major muscles?
Hip -Position = 20° flexion -Major muscles = extensors Knee -Position = 0-5° flexion -Major muscles = quadriceps Ankle -Position = 0° -Major muscles = pretibials
Stance Phase: LR

- Critical events = __________
- Opposite limb = ______
- hip stability, controlled knee flexion, ankle PF
- PSw
Stance Phase: LR Hip -Position? -Major muscles? Knee -Position? -Major muscles? Ankle -Position? -Major muscles?
Hip -Position = 20° flexion -Major muscles = extensors, abductors Knee -Position = 15° flexion -Major muscles = quadriceps Ankle -Position = 5° PF -Major muscles = pretibials
Stance Phase: MSt

Stance Phase: MSt Hip -Position? -Major muscles? Knee -Position? -Major muscles? Ankle -Position? -Major muscles?
Hip -Position = 0° -Major muscles = abductors Knee -Position = 5° flexion -Major muscles = quadriceps ->quiet Ankle -Position = 5° DF -Major muscles = gastroc/soleus
Stance Phase: TSt
- Progression over the stance limb continues past the forefoot. Body is ahead of stance limb.
- Critical events = __________
- Opposite limb = ______
- controlled ankle DF with heel rise
- TSw
Stance Phase: TSt Hip -Position? -Major muscles? Knee -Position? -Major muscles? Ankle -Position? -Major muscles?
Hip -Position = 20° extension -Major muscles = none Knee -Position = 5° flexion -Major muscles = none Ankle -Position = 10° DF -Major muscles = gastroc/soleus
Stance Phase: PSw
- Rapid unloading of the limb with weight transfer to opposite limb, starting the second period of double limb support.
- Critical events = __________
- Opposite limb = ______

Why do we analyze gait?
- Identify deviations in gait in order to address with intervention.
- Determine functional ambulation capability across variety of environments.
- Assess balance, safety, endurance, energy expenditure as it relates to walking.
- Determine need for assistive devices/orthotics.
- Evaluate the effectiveness of your interventions; describe how your interventions impacted gait.
The goal of analyzing gait is to identify _________ and design appropriate __________ to treat impairments (function/participation limitations.
- deviations
- interventions
