Answer 2

Dorsiflexion
Eversion
Adduction

Question 3

What are the CKC action of the STJ

closed kinetic chain

Answer 3

Plantarflexion & Adduction of talus

& eversion of the calcaneus??

Question 4

From STJ neutral the, what is the ratio of inversion: eversion?

Answer 4

STJ inversion:eversion in the ratio of 2:1

Question 5

The ankle joint is fixed ? T/F

Answer 5

False

Question 6

What is the primary motion of the ankle joint?

Answer 6

DF/PF &

adduction/abduction respectively

Question 7

What motion occurrs at lesser rays?

Answer 7

Fibrocartilage surface allows them to move plantarly & posteriorly

Question 8

The Midtarsal joint is comprised of which joints?

Answer 8

Calcaneocuboid & talonavicular joints

Question 9

How many axes does the Midtarsal joint have & what are they?

Answer 9

2 axes

Longitudinal & oblique

Question 10

Where are the longitudinal & oblique axes of the MTJ located?

Answer 10

9 degrees from sagittal plane??

15 degrees form the transverse plane??

Question 11

List Root’s normal foot critera (6)

Answer 11

1. vertical calcaneus & tibia
2. STJ neutral
3. MTJ axes are locked in their pronated positions
4. All metatarsals are contacting the ground & forefoot parallel to rearfoot
5. No muscle support necessary to maintain structural integrity of the foot (bone & ligaments should hold foot together)
6. Gastrocnemius contraction exerts a nearly continuous plantarflexory force at the AJ, loading the forefoot

Question 12

How many degrees of DF is required by the lesser rays in gait?

Answer 12

65 degrees of DF required in gait

This function is done by the sesamoids in the 1st Ray

Question 13

If the 1st Ray is plantarflexed, it may be congenital or acquired. If acquired it may be due to?

Answer 13

1. Weak gastrocnemius
2. hypertonicity of fibularis longus,
3. Weak tibialis anterior
4. 2 degrees - uncompensated forefoot varus
5. weak intrinsic muscles that DF the hallux

Question 14

A hypermobile 1st Ray may cause what foot conditions?

Answer 14

Cavus foot type in NWB,
Callus under submet 2,
juvenile HAV,
neuroma or plantar fasciitis

Question 15

An acquired PF 1st Ray is characterised by being bilateral [T/F] and having abnormal ROM [T/F]?

Answer 15

False

True

Question 16

The 5th Ray is single or triplanar axis?

Answer 16

Triplanar axis

Question 17

List features of mallet toe

Answer 17

Only DIPJ is flexed

with MPJ & PIPJ extended

Question 18

List features of claw toe

Answer 18

both IPJ’s are flexed with the MPJ extended

Question 19

List features of hammer toe

Answer 19

Only PIPJ is flexed with MPJ & DIPJ extended

Question 20

Which ligaments stabilise the MTJ?

Answer 20

Plantar calcaneocuboid (short plantar lig)
Calcaneonavicular (long plantar ligament)
Bifurcate ligament

Question 21

During normal gait the ankle joint has how many degrees of PF & DF?

Answer 21

20 degrees PF

10 degrees DF
