Question 1

what are the normative values for navicular drop?

Answer 1

10-15mm depending on foot size

Question 2

what are the normative values for hamstring flexibility

Answer 2

6-70

Question 3

what are the normative values for hip joint transverse rotation?

Answer 3

45 deg internal and external

only 5-20 required for normal gait

Question 4

what are the normative values for MTJ ROM?

Answer 4

• equal inversion and eversion, difficult to quantify

Question 5

what are the normative values for 1st MPJ DF

Answer 5

65 deg (ranges fr 50-90 in literature)

• -> look a both legs to see if its congenital or acquired
• remember to start with the hallux phalanges in line with the 1st metatarsal as your”0”/starting point
• if you want a proper measure use a Roukis goniometer: it doesn’t lock MTJ properly but its better than a kick in the dick

Question 6

what are the normative values for AJ DF?

Answer 6

10 with knee extended NWB 8-26 in lit
–> modified lindcombe template etc. if you want a better
- feel what type of resistance e.g. bony or spongy block
-

Question 7

what are the normative values for STJ ROM?

Answer 7

10 inversion, 28 eversion (2:1 ration generally but it varies)

Question 8

what are the normative values for Ffoot-Rfoot position?

Answer 8

6 deg varus s normal

Question 9

what are the normative values for 1st ray ROM?

Answer 9

“thumbs breadth”

Question 10

when we are testing AJ DF why do we slightly supinate the foot ?

Answer 10

to take out STJ , so making it harder for the talocrural joint

Question 11

when testng gastroc/sol tightness- why does bending the knee “take out” gastrocnemius?

Answer 11

because of its origin (femur) and insertion (calc via achilles tendon) it would be pulling in a 90 degree angle which it can’t actually do..

Question 12

what would you do for a patient that has structural LLD?

Answer 12

• if it is less than 1cm i might just to a heel raise internally e.g. add to orthotic
• if greater than 1cm then external full length

Question 13

what are the 3 things we look for with the knee?

Answer 13

1. FP alignment: using the tape measure: ASIS–> middle of AJ
2. SP alignment: hyperextension?
3. patella (ew): should move a 1/3 of a width medial nd lateral and should be = both sides

Question 14

how would you get a proper measurement for looking at alignment of the whole leg/knee FP

Answer 14

WB x-ray of hip–> foot and take a measure

Question 15

what does crepitus in the knee/patella suggest?

Answer 15

OA changes potential
