CON: gracilis, sartorius

some of everything in ankle

18
Q

Muscles active during initial swing

A

CON: iliacus, gracilis, sartorius, short head of biceps femoris
ECC: EDL, EHL, tibialis anterior

19
Q

Muscles active during midswing

A

CON: knee flexors, tibialis anterior, EDL, EHL

20
Q

Muscles active during terminal swing

A

ECC: hamstrings, glute max, glute med, tibialis anterior, EHL, EDL
CON: TFL, quads

21
Q

Flat foot contact

A

-Compensate for weak quads
-Heel pain
-Excess knee flexion/plantarflexion in TSw

Decreases forward momentum of tibia, poor position for heel rocker, decreased shock absorption

22
Q

Excess plantarflexion

A

SLS: PF hypertonicity, weak quads, ankle pain (decreases forward progression of tibia over ankle and forefoot)

SLA: weak pretibials, PF hypertonicity, lack of selective DF control in TSw (interferes with foot clearance, and foot position for IC)

23
Q

Excess dorsiflexion

A

WA: secondary to excess hip or knee flexion (increases demand on hip and knee extensors, decreases stability)

SLS: weak calf, intentional to lower opposite limb for contact (TSt), excess midfoot DF because of limited ankle mobility (interferes with heel riser and decreases step length of opposite limb)

24
Q

Overactivity of tib. anterior, tib. post, or soleus in weight acceptance and single leg stance can lead to..

A

excess inversion

25
Q

Excess inversion could be caused by what in single leg advancement

A

weak peroneals, lack of motor control of pretibials

26
Q

Weak tib. posterior and soleus in WA and SLS could lead to…

A

excess eversion

27
Q

What is the cause of excess eversion during SLS?

A

valgus deformity, low arch

28
Q

What is the cause of excess eversion in SLA?

A

weak tib ant, peroneal hypertonocity

29
Q

What can inadequate extension of the toes result in?

A

interferes with forward progression, decreases step length of opposite limb

30
Q

Most likely causes of limited knee flexion and what they can effect?

A

WA: weak quads, 2nd to forefoot contact w/ tight calf
- decreased shock absorption, decreases forward momentum of tibia

SLA: 2nd to excess hip flexion or no heel off in TSt, impaired motor control resulting in inability to rapidbly flex the knee, extensor hypertonicity, limited thigh advancement 2nd to hamstring hypertonicity or hip flexor weakness
- interferes with foot clearance in ISw, decreased knee flexion in PSw = decreased knee flexion in ISw

31
Q

Most likely causes of excess knee flexion and what they can effect?

A

SLS: knee flexor hypertonicity, 2nd to excess hip flexion, 2nd to decreased contralateral limb stance stability in WA, posterior pelvic tilt
- increased demand on PF, quads, and hip ext.

SLA: weak quads, hamstring hypertonicity
- decreases step length, interferes w/heel first contact

32
Q

Most likely causes of varus/valgus and what they can effect?

A

joint or ligamentus instability, bony deformity, dysfunctional subtalar joint, 2nd to lateral trunk lean (valgus)
- decreased limb stability, compensation prox or dist to knee

33
Q

Start and end of initial contact

A

foot contact
foot contact

34
Q

A

foot off
feet adjacent to one another

39
Q

A

feet adjacent to one another
ipsilateral vertical tibia

40
Q

start and end of terminal swing

A

ipsilateral vertical tibia
