What is the action of iliopsoas(hip

region)

Flexion of the hip TERM 2

over-activity of

iliopsoas

DEFINITION 2 contributes to anteriorly tilted pelvis.Use thomas test to assess tightness. TERM 3

exercise for

iliopsoas

DEFINITION 3 sit ups- iliopsoas are the primary movers. also use lunge stretch. A TERM 4

5 structures of lower extremity

DEFINITION 4 pelvic girdlehip jointknee jointankle jointsubtalar joint TERM 5

Ball-and-socket joint(for hip joint)

DEFINITION 5 head of femur articulates with acetabulum.

(hip joint) head of femur covered with

cartilage

labrum- in acetabulum adds depth to joint serves as cushion TERM 7

(hip joint) body structure is strong

DEFINITION 7 strong ligaments/musclesstable joint and good ROM TERM 8

Motion in pelvis allows

DEFINITION 8 greater ROM of lower extremity TERM 9

Hip joint motions parallel shoulder joint

motions

DEFINITION 9 flexion, extension, abduction, adduction, (horizontal as well), internal and external rotation. TERM 10

Thomas test

DEFINITION 10 in which knee does not flex is positive for rectus femoris vs. iliopsoas.

Posteriorly tilted pelvis...

shorten gluteus ( length tension relationship) TERM 17

anteriorly tilted pelvis

DEFINITION 17 lengthens glutes(length tension relationship) TERM 18

what is gluteus max. important for

DEFINITION 18 important for explosive LE movements such as sprinting and jumping. TERM 19

Gluteus medius

action

DEFINITION 19 hip abduction ( open chain) - important to prevent valgus forces on knee. -Especially when jumping and landing.important to stabilizing the pelvis when standing/walking/running/ sprinting on one leg (closed chain) (hip adductors when landing)and external and internal rotation of hip TERM 20

3 hamstrings

DEFINITION 20 semitendinosus, semmimembranosus, biceps femoris.

both semi's are considered?

medial hamstring TERM 22

biceps femoris is considered

DEFINITION 22 lateral hamstring TERM 23

all hamstrings cause...

DEFINITION 23 extension of hip and flexion of knee. TERM 24

over-activity of hamstrings

DEFINITION 24 cause a posteriorly tilt of pelvis. TERM 25

Semi's also cause

DEFINITION 25 internal rotation of tibia

anteriorly tilt limits hip ext.

and

limites glute development TERM 32

Closed chain (glute medius)

DEFINITION 32 leg is fixed, GM stabilizes pelvis by preventing lateral tilt (frontal plane) to opposite side. TERM 33

Open chaid (glute medius)

DEFINITION 33 prevents hip from adducting and putting it in dangerous position for ACL. TERM 34

Six deep lateral rotator

muscles

DEFINITION 34 external rotation of hip TERM 35

lateral rotators key point

DEFINITION 35 piriformis is near the sciatic nerve. Tightness in piriformis may contribute to sciatic pain and externally rotate hip (over-active)

Semitendinosus muscle action

extension of hip, flexion of hip. internal rotation and tibia. TERM 37

Semitendinosus tightness can cause.

DEFINITION 37 tight hamstring can cause posterior tilt of pelvis.same with semimembranosus. TERM 38

semitendinosus over-

activity

DEFINITION 38 over-activity of medial hamstrings can create internal rotation of tibia\same with semimembranosus. TERM 39

Semimembranosus muscle action

DEFINITION 39 extension of hip, flexion of knee, internal rotation of tibia. TERM 40

Bicep femoris action

DEFINITION 40 extension of hip, flexion of kneeexternal rotation of tibia.

piriforms causes external rotation however

when hip is flexed to 90 degrees....

it becomes an internal rotator.important to prevent internal rotation and valgus forces of the knee (especially with landing) piriformis syndrome. TERM 47

action of vastus lateralis

DEFINITION 47 extension of knee- pulls patella laterally TERM 48

when vastus lateralis over-

acts

DEFINITION 48 chondromalacia TERM 49

actions of vastus medialis-

DEFINITION 49 Extension of knee. Pulls patella medially. very active in last 30 degrees of leg extension. TERM 50

when weakened the vastus medialis

DEFINITION 50 due to excessive quad contractions without moving into extension (riding biek) may allow laterally displacement of patella.

Rectus femoris action

flexion of hip and extension of knee.only quadriceps muscle that crosses over the hip. TERM 52

Hamstrings-( semitendinosus,

semimembranesus. )

DEFINITION 52 extension of hip and flexion of knee. Internal rotation of knee. TERM 53

hamstrings ( biceps femoris)

DEFINITION 53 extension of hip. flexion of knee. External rotation of tibia. TERM 54

Tibiofemoral joint(knee)

DEFINITION 54 Modified hinge jointtwo condyles of femur articulate with tibial plateaus/menisciNote: intercondyloid eminence and notch: ACL tearPatella articulates with patellar surface of femur.- patellofemoral jointbony stability is weak. helped by considerable ligaments and cartilage. TERM 55

The tibiofemoral structure

DEFINITION 55 Menisci are circular rims of cartilageLateral and medial.- Provide shock absorption. Protects bony ends stability of knee.outer portion is thicker than outer portion more vascular, supply minimal by 20sMedial menisci attached to platear..where as lateral menisci has greater freedom of movement.

Piriformis syndrome

Tightness of the piriformis muscle compressing the sciatic nerve contributing to pain down the posterior aspect of the leg.lack of stretching into internal rotation.extensive hip extension and abduction strengthening exercises. TERM 62

Chondromalacia

DEFINITION 62 Degeneration of cartilage on surface of patella. Due to patella rubbing on femoral condyle. creates pain, on movement, swelling, grating during knee extension/flexion. TERM 63

Cause of chondromalacia

DEFINITION 63 patellar tracking problems due to vastus lateralis or weakness. TERM 64

what to do to prevent chondromalacia

DEFINITION 64 strengthen vastus medialis by training complete extension. - short arch quads (0-30 degree of extension)Look for structural imbalances for predisposed - genu valgum, tibial torsion, pronated feet.be aware of activities that may contribute - cycling, recovering from knee problems. TERM 65

Osgood schlatter

disease

DEFINITION 65 Repeated overuse of knee extensors creating tendonitis of patellar tendon on tibial turbosity. - especially during growing periods.swelling, pain on activity and kneeling

treatment of osgood disease

early recognitionrest and icestop exercises that involve knee extension (quads)cho-pat TERM 67

Anterior cruciate tears

DEFINITION 67 valgus force with rotation while weight bearingexcessive flexion of weight bearing knee (skiing/squats)Anterior blow to femur with foot fixed (anterior translation of tibia.) TERM 68

Prevention for anterior cruciate

tears

DEFINITION 68 Train hamstringstrain eccentricallytrain knee proprioceptorsincrease fitness to minimize fatigue TERM 69

Posterior cruciate tears

DEFINITION 69 Posterior translation of tibia relative to femuranterior blow to tibia avoid hyperextension of knee. TERM 70

Meniscal tears

DEFINITION 70 tends to be damaged more than the lateralDue tomedial meniscus has less ability to move in the knee jointmore stresses on knee tend be directed to medial meniscus

4 knee rules for proper knee mechanics with

exercise, landing, and ADL

  1. Knee must be aligned2. dont go past 90 degrees3. dont hyper extend4. dont go past toes. TERM 77

to test if they do 4 rule right

DEFINITION 77 test for proper squate. 60% of body weight. Then they are ready for pliometics TERM 78

teach and train proper change of direction

and deceleration

DEFINITION 78 Maintaining lower center of gravity is key. TERM 79

Train hamstrings as much as you train

quadriceps

DEFINITION 79 traditional leg curlsstability ball hip extensions- knee in extension, more hamstring due to active insufficiency.knee in flexion - more gluteus maximus TERM 80

DEFINITION 84 joined at both proximal and distal tibiofibular jointsligaments and a strong, dense interosseus membrane between tibia and fibula shafts provide supportminimal movement possibledistal joint becomes sprained occasionally in heavy contact sporthigh ankle sprains TERM 85

bones (ankle joint)

DEFINITION 85 distal malleoli of tibia (medial) and fibula ( lateral)serve as pulley for posterior tendons to increase mechanical advantage of muscles in performing inversion and eversion actions.

action of gastrocnemius(ankle and knee)

plantar flexion of ankleflexion of kneeremember knee needs to be in extension for stretching and strengthening : lateral head externally rotates foot; medially head internally rotates foot TERM 92

gastrocnemius overactivity and fast twitch
