Q

anterior (forward) pelvic rotation produces ____rotation on the stance hip

posterior rotation produces hip ____ rotation on the stance hip

A

anterior; medial rotation
posterior; lateral rotation

19
Q

describe forward bending (pelvifemroal motion)

A

 Head and upper trunk initiates flexion, pelvis shifts posteriorly
 Trunk continues to forward bend, controlled by extensors
 Once vertebral segments are at end range, pelvis rotates forward/anteriorly tilts
 Pelvis continues to rotate forward until full muscle length is reached

20
Q

the LOG at the hip creates

A

an extensor moment counterbalanced by ligaments/iliopsoas tension

21
Q

TFL function

A

flexion
abduciton
MR

22
Q

what group of mm can help flex the hip from extended position?

A

hip ADDuctors

(pectineus, adductor longus/magnus, gracilis)
gracilis (can help flex hip if knee is extended)

23
Q

what muscles help adduct the hip when leg is in ER and ABD?

A

biceps femoris long head
glute max
QF
Obturator externus

24
Q

T/F there are no primary medial rotators;
anteriro glut med, min, TFL, adductors all help medially rotate

A

True

25
Q

what muscle is a primary compensator?

A

TFL-
Because it will flex hip as you try to isolate abduction

26
Q

T/F glute med is a primary external rotator

A

FALSE- that’s why we don’t like clamshells because it’s not targetting external rotation like we think.

27
Q

primary hip lateral rotators

A

glute max
OI AND OE
gemelli S and I
QF
Piriformis (neutral or less than 90 hip)

28
Q

when is bursa painful?

A

with compression

29
Q

when does tendon cause pain?

A

contracted or resisted or pulled

tx: isometric

30
Q

when does peritendon cause pain?

A

stretch or in the LONGEST position

(quadricep tendon: most pain w/ end range knee flexion)

TX: massage

31
Q

preferred MMT position for iliposoas

A

supine > sitting

32
Q

how to target the hamstring groups more specifically

A

semis (medial) - IR the tibia
biceps (lateral) - ER the tibia

33
Q

dominant muscles (weak muscles)

A

TFL & AGM (PGM & glut min)
TFL (iliopsoas)
Hip adductors (abductors)
Hamstrings as hip extensors (Glut Max)
Hamstrings as knee extensors in closed chain (Quads)
Biceps femoris in LR (piriformis & LRs)
Medial hams (Biceps femoris)

34
Q

PAILS/RAILS Benefits

A
  • Bypass the stretch reflex
  • Creates cortical mapping
  • Increase neural drive to the tissue
  • Cause a cellular adaptation in the tissue
  • Increase blood flow to both the PAILS and RAILs tissue
35
Q

when does hip IR occur?

A

when extending towards 0 degrees from a flexed position
- Flexed 60-100 degrees

36
Q

true function of hip IR

A

Drives force into the ground

37
Q

hip pain with mobility deficits CPG

A
  1. insidious onset, first w/ WB
  2. mod anterior / lateral hip pain during WB
  3. morning stiffness <1 hr in duration after wakening
  4. Hip IR ROM less than 24 degrees
  5. IR and hip flexion 15 degrees less than nonpainful side
  6. increased hip pain associated with passive hip IR
38
Q

Hip OA CPR

A
  1. squatting aggravates
  2. hip flexion AROM causes lateral hip pain
  3. scour test with adduction causes lateral hip or groin pain
  4. active hip extension causes pain
  5. passive IR less than or equal 25
39
Q

cam impingement more prevalent in

A

males (younger)

40
Q

Pincer impingement more common in

A

middle-aged, active women

41
Q

Usually between 4-8 years old (male)
 Child tends to be shorter
 Deformity of the femoral head
 Usually treated conservatively. If surgery is indicated, may involve femoral osteotomy

A

legg-calve-perthes disease

42
Q

 Usually between 10-15 years old
 Child tends to be overweight
 Displacement of the femoral neck
 Usually treated surgically- internal fixation

A

SCFE
