how do we assess the IP joint?

Answer 3

assess that plantarflexion from a fully extended position is occurring

Question 4

what is the range of motion for the metatarsophalangeal joint?

Answer 4

greater than 65 degree for propulsion

Question 5

how is the MTP joint assessed?

Answer 5

dorsiflexing the digit on the corresponding metatarsal

Question 6

what joint is the center for motion?

Answer 6

MPJ

Question 7

what doe the 1st ray consist of?

Answer 7

1st cuneiform and 1st metatarsal

Question 8

what degree doe the axis of the 1st ray angulate?

Answer 8

45 degree from the frontal and sagittal planes and only slightly from the transverse plane

Question 9

1st ray motion occurs in the 3 planes how?

Answer 9

via dorsiflexion(inversion) and plantarflexion(eversion) being the primary motions

Question 10

best way to assess the 1st ray?

Answer 10

place the STJ in neutral with the MTJ pronated

Question 11

if plantarflexion exceeds dorsiflexion, what does this indicate about the 1st ray?

Answer 11

it indicates plantar flexed 1st ray deformity

Question 12

if dorsiflexion exceeds plantarflexion, what does this indicate about the 1st ray?

Answer 12

it indicates dorsiflexed 1st ray deformity

Question 13

what is the angle of 1st ray motion?

is this an example for hypermobiity?

Answer 13

10-20 degrees

nah

Question 14

what are the axis that the midtarsal joint is measured from?

Answer 14

oblique axis

longitudinal axis

Question 15

what is the total range of motion at the MTJ dependent on?

Answer 15

STJ position

Question 16

affect of STJ supination at the MTJ?

Answer 16

decreases ROM

Question 17

affect of STJ pronation at the MTJ?

Answer 17

increases ROM

Question 18

the STJ occurs in what planes?

movements for:
supination
pronation

Answer 18

all 3 planes simultaneously

pronation
inversion
adduction

dorsiflexion
eversion
abduction

Question 19

degrees of calcaneal inversion with supination for the STJ?

degrees of calcaneal eversion with pronation for the STJ?

total minimum range?

Answer 19

4-6

4-6

8-12 degrees

Question 20

how do we measure the STJ ROM?

Answer 20

place patient in the prone

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

Question 21

for the ankle joint what is the degree for dorsiflexion?

how do we measure it?

Answer 21

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)

Question 22

what is the test used to measure ankle joint ROM?

Answer 22

silverskolid test

Question 23

what positions is the knee joint measured?

what planes are measured and degrees obtained normally?

Answer 23

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

120-130 degrees flexion any further and genu recurvatum

Question 24

what plane is the ROM for the hip joint taken?

Answer 24

transverse plane only

45 internal, 45 external rotation

Question 25

how do we lock the MTJ?

Answer 25

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

Question 26

how is the calcaneus stance measured relaxed? why is this a good measurement?

Answer 26

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

Question 27

how is the calcaneus stance measured neutral?

Answer 27

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

Question 28

where do we first observe angle and base of gait?

Answer 28

observe first in gait analysis assess by bisecting the foot in relation to a straight line along the sagittal plane

Question 29

what degrees are taken from the malleolar position?

Answer 29

13-18 degrees when knee joint extended and STJ neutral

Question 30

how do we measure frontal plane leg deviation?

Answer 30

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

Question 31

inverted leg on frontal plane is? everted leg on frontal plane is?

Answer 31

tibial varum tibial algum

Question 32

apex deformity of the MTJ indicates? inversion of the forefoot on rearfoot? eversion of the forefoot on the rearfoot? how are these assessed?

Answer 32

forefoot varus/valgus forefoot varus forefoot valgus STJ must be in neutral with MTJ maximally pronated and locked to assess
