What are the two components of weight acceptance task?

Initial contact & loading response

Is preswing part of stance or swing phase

stance phase

What are the two tasks of stance phase?

weight acceptance & single limb support

What are the two subphases of single limb support task of stance phase?

Midstance & terminal stance

Which rocker is initial contact & loading response (weight acceptance)?

1st Rocker/heel rocker

Which rocker is midstance?

2nd Rocker/ankle rocker

Which rocker is terminal stance?

3rd Rocker/forefoot rocker

What are the 3 subphases of swing phase?

initial swing, midswing, and terminal swing

What percentage of the gait cycle is considered initial contact?

0-2%

What percentage of the gait cycle is considered loading response?

2-10%

When does loading response begin?

after initial contact (of R foot)

When does loading response end?

when contralateral (L) limb lifted for swing

What percentage of the gait cycle is considered midstance?

10-30%

When does midstance begin?

when the contralateral (L) foot leaves the ground

When does midstance end?

when bodyweight travels forward until aligned over the forefoot

What percentage of the gait cycle is considered terminal stance?

30-50%

When does terminal stance begin?

with body weight over forefoot (~heel rise of the stance limb) (COM anterior to foot)

When does terminal stance end?

when contralateral (L) foot hits ground

What percentage of the gait cycle is considered preswing?

50-60%

When does preswing start?

when contralateral (L) foot hits the ground

When does preswing end?

with ipsilateral (R) toe off

What percentage of the gait cycle is considered initial swing?

60-75%

When does initial swing begin?

when foot leaves ground

When does initial swing end?

when swing foot opposite contralateral foot (when both feet are next to eachother)

What percentage of the gait cycle is considered mid swing?

75-85%

When does mid swing begin?

when swing foot is opposite to contralateral foot (when both feet are next to eachother)

When does mid swing end?

when tibia is vertical

What percentage of the gait cycle is considered terminal swing?

85-100%

When does terminal swing begin?

when tibia is vertical

When does terminal swing end?

when foot strikes floor

What are the 4 spatial descriptors (m)?

Stride length

Step length

Step Width

Foot angle

What are the 3 temporal descriptors (sec)?

Cadence

Stride time

Step time

What is the spatial-temporal descrptor (its both)?

Walking velocity
