MUSCLES OF THE HIP Flashcards
what is the action of psoas major
hip flexion, lateral flexion of lumbar spine
what is the action of illiacus
hip flexion
what is the action of sartorius
hip flexion, abduction and lateral rotation
knee flexion and medial rotation
what is the action of TFL
hip flexion, abduction and medial rotation
assists knee extension
what is the action of gluteus maximus
hip extension and lateral rotation
upper fibres - abduct hip
lower fibres - adduct hip
what is the action of gluteus medius
anterior fibres - hip abduction, medial rotation, flexion
posterior fibres - hip abduction, lateral rotation, extension
what is the action of adductor longus
hip adduction and flexion
what is the action of adductor magnus
hip adduction and extension
palpate illiopsoas
patient supine
identify sartorius and adductor longs
place fingers deep in between (femoral triangle floor)
ask patient to preform sit up
(CAN ONLY PALPATE TENDON ON THE LESSER TROCHANTER)
palpate sartorius
patient supine
flex, abduct, laterally rotate hip, flex knee
resist
palpate from ASIS to insterion on medial tibia
runs down medial thigh
palpate TFL
patient supine
flex, abduct and medially rotate hip
resist extension and adduction
palpate from iliac crest to lateral proximal thigh
palpate gluteus maximus
patient prone lying
flex knee to 90
ask model to extend hip
palpate from PSIS and posterior iliac crest to proximal thigh
palpate gluteus medius
patient in side lying
knee extension and hip abduction
resist hip flexion and medial rotation
palpate adductor longus
patient supine
flex hip and resist adduction
palpate from medial femoral triangle to mid thigh
palpate adductor magnus
prone lying
extend hip and resist adduction
palpate medial thigh to the adductor tubercle on medial supracondylar line (posterior)
