Q

describe what occurs in IC and the critical events that occur in the phase of gait

A

this is the instant the foot hits the ground

critical events → heel first contact

Q

describe what occurs in LR and the crucial events that occur in this phase of gait

A

shock is absorbed as forward momentum is preserved. A foot flat position is achieved

critical events → hip stability, controlled knee flexion and ankle PF

Q

describe what occurs in MSt and the critical events that occur in this phase of gait

A

the body progresses over the foot in a controlled manner. First instance of single limb support

critical events → controlled tibial advancement

Q

describe what occurs in TSt and the critical events that occur in this phase of gait

A

progression over the stance limb continues past the forefoot. Body is ahead of stance limb

critical events → controlled ankle DF w/heel rise

Q

describe what occurs during PSw and the critical events that occur in the phase of gait

A

rapid unloading of limb with weight transfer to opposite limb, starting the second period of double limb support

critical events → passive knee flexion to 40º, ankle PF, and 60º of MTP extension

17
Q

describe the relative position of each joint in the LE during PSw

A

Hip → 10º extension

Knee → 40º flexion

Ankle → 15º PF

MTP → 60º extension

18
Q

what major muscle groups are working during PSw?

A

hip adductors

as we progress through this phase tibialis anterior starts to activate going into ISw

19
Q

describe what occurs during ISw and the critical events that occur during this phase of gait

A

the thigh begins to advance as the foot leaves the floor

Critical events → hip flexion, knee flexion

20
Q

describe the relative position of each joint in the LE during ISw

A

Hip → 15º flexion

Knee → 60º flexion

Ankle → 5º PF

21
Q

what major muscle groups are active during ISw?

A

Hip flexors

knee flexors

pretibials

22
Q

describe what occurs during MSw and the critical events that occur during this phase of gait

A

thigh continues to advance, knee beings to extend as foot clearance is maintained

Critical events → continued hip flexion, foot clearance

23
Q

describe the relative position of each joint in the LE during MSw

A

Hip → 25º flexion

Knee → 25º flexion

Ankle → 0º DF

24
Q

what major muscle groups are active during MSw?

A

Hip flexors

knee flexors

pretibials

25
describe what occurs during TSw and the critical events that occur in this phase of gait
the leg reaches out to achieve step length critical events → knee extension
