Q

affect of STJ supination at the MTJ?

A

decreases ROM

17
Q

affect of STJ pronation at the MTJ?

A

increases ROM

18
Q

the STJ occurs in what planes?

movements for:
supination
pronation

A

all 3 planes simultaneously

pronation
inversion
adduction

dorsiflexion
eversion
abduction

19
Q

degrees of calcaneal inversion with supination for the STJ?

degrees of calcaneal eversion with pronation for the STJ?

total minimum range?

A

4-6

4-6

8-12 degrees

20
Q

how do we measure the STJ ROM?

A

place patient in the prone

bisect the calcaneus and lower 1/3 of the leg to measure both inversion and eversion components

21
Q

for the ankle joint what is the degree for dorsiflexion?

how do we measure it?

A

10 degrees

measure the angle formed by the plantar aspect (all the way from the calcaneus to skin beneath 5th met head) of the foot and distal lateral 1/3 of leg (from musculotendinous junction of the triceps surae to proximal to lateral malleolus)

22
Q

what is the test used to measure ankle joint ROM?

A

silverskolid test

23
Q

what positions is the knee joint measured?

what planes are measured and degrees obtained normally?

A

flexion/extension
*not measured in the frontal or transverse plane

120-130 degrees flexion any further and genu recurvatum

24
Q

what plane is the ROM for the hip joint taken?

A

transverse plane only

45 internal, 45 external rotation

25
Q

how do we lock the MTJ?

A

patient prone on exam table with knee placed in frontal plane and STJ in neutral so now that forefoot to rearfoot measurement

26
Q

how is the calcaneus stance measured relaxed?

why is this a good measurement?

A

measured bisection of calcaneus in relation to floor so that measurements are in the range of everted to rectus

because frontal plane leg deviation is included due to the patient standing

27
Q

how is the calcaneus stance measured neutral?

A

patient inverts and everts the foot while bearing weight and remaining in angle and base of gait

palpate for congruity of talar dome in ankle mortise

measure bisection of calcaneus in relation to floor

28
Q

where do we first observe angle and base of gait?

A

observe first in gait analysis

assess by bisecting the foot in relation to a straight line along the sagittal plane

29
Q

what degrees are taken from the malleolar position?

A

13-18 degrees when knee joint extended and STJ neutral

30
Q

how do we measure frontal plane leg deviation?

A

measure tibial position in frontal plane for tibial varum, valgus, neutral/rectus by placing patient in neutral calcaneal stance position and then place the goniometer on posterior bisection of lower 1/3 of leg

31
Q

inverted leg on frontal plane is?

everted leg on frontal plane is?

A

tibial varum

tibial algum

32
Q

apex deformity of the MTJ indicates?

inversion of the forefoot on rearfoot?

eversion of the forefoot on the rearfoot?

how are these assessed?

A

forefoot varus/valgus

forefoot varus
forefoot valgus

STJ must be in neutral with MTJ maximally pronated and locked to assess
