Q

gluteus medius and minimus

A

O = lateral ilium below crest
I = greater trochanter

17
Q

hip external rotators

A

6 deep external rotators
considered as one
gluteus maximus

18
Q

hip internal rotators

A

no primary muscle
glut min and med, TFL ST SM gracilis

19
Q

lombards paradox requirements

A

sit to stand
hip ext and knee ext
rectus femoris agonistic for knee ext but antagonist for hip ext
hamstring agonist for hip extension but antagonist for knee extension

20
Q

lombards paradox description

A

extensor muscle at knee and hip have greater level arm than flexors
quads activated to greater extent
only RF of quads span hip
means there is a net extensor torque at the knee and net extensor torque at hip

21
Q

femoroacetabular impingement

A

abnormal growth of femur or acetabulum
causes butting together
damages cartilage

22
Q

risk factors for femoroacetabular impingement

A

osteoarthritis
young athletic groups

23
Q

iliotibial band syndrome

A

if iliotibial band is tight it can cause inflammation on lateral aspects of knee
friction between band and lateral ocndylle of femur

24
Q

iliotibial band

A

fibrous reinforcement of the TFL

25
Q

hamstring strain

A

most common ink football
91% non contact
bicep femoris

26
Q

risk factor for HSI

A

previous strain
fatigue
strength imbalance
poor flexibility
