What are the 5 stance phases in standard and in rancho?
Standard Rancho
- Heel strike : Initial Contact
- Foot flat : Loading Response
- Midstance : Midstance
- Heel off : Terminal stance
- toe off : Pre-swing
What are the 3 swing phases in standard and in rancho?
Standard Rancho
- Acceleration : Initial Swing
- Midswing : Midswing
- Deceleration : Terminal swing
When is loading response (rancho)?
between initial contact and the beginning of the swing phase of the other leg (loading so you can swing opp)
When is midstance (rancho)?
point in stance phase when the other foot is off the floor until the body is directly over stance limb
When is terminal stance (rancho)?
begins with the heel of the stance limb rising and ends when the other foot touches the ground
When is pre-swing (rancho)?
begins when the other foot touches the ground and ends with stance foot reaches toe off
When is initial swing (rancho)?
begins when stance foot lifts from the floor and ends with max knee flexion during swing
When is midswing (rancho)?
begins with max knee flexion an dends when tibia is perpendicular to ground
When is terminal swing (rancho)?
begins when the tibia is perpendicular to the floor and ends when the foot touches the ground.
What percent of gait is stance phase and what percent is swing?
60% stance and 40% swing
What percent of the gait cycle is double support and when does that occur?
20% double support, 80% single support
10% between R initial contact and L pre-swing
10% between L initial contact and R pre-swing
How many degrees of hip, knee, and ankle motion are needed for normal gait (6 motions)?
Hip Flexion: 30 Hip Extension: 10 Knee flexion: 60 Knee extension: 0 Ankle dorsiflexion: 0-10 Ankle plantarflexion: 0-20
During initial contact what muscles place the ankle in dorsiflexion for heel strike and prepare to lower the foot towards the ground?
Ankle dorsiflexors
During loading response what muscles act eccentrically to control lowering of the foot to the ground?
During the latter portion of the phase what muscles eccentrically control dorsiflexion as the tibia moves over the foot?
During Loading response what muscle eccentrically controls pronation of the foot?
ankel dorsiflexors
ankle plantarflexors
Posterior tibialis
During what phase do hip abductors contract to stabilize the pelvis and prevent contralateral hip drop?
midstance and terminal stance as weel
During what phase do plantar flexors begin to work concentrically?
terminal stance
What are the ankle dorsiflexors doing in initial swing and why?
contracting concentrically to clear the foot from the ground
What are the ankle inverters doing during terminal swing and why?
contracting concentrically in order to prepare the foot for initial contact
What is the average BOS for adults?
2-4 inches
What is the average cadence for adults?
110-120 steps per minute
