Hip Movement Patterns

What is the patient position of during hip abduction movement pattern?

side lying, affected side up; bottom leg flexed, other leg straight

Hip abduction MP is designed to assess what?

patient’s lateral mechaniscm in open chain

What is assessed during hip abduction MP?

smooth arc of motion

able to reach 30º without elevating ilium

able to maintain proper position and stability of leg and pelvis

What does an early hip hike indicate during hip abduction MP?

overactive quadratus lumborum

What does the pelvis rolling forward usually indicate during hip abduction MP?

use of hip extension strategy to achieve abduction

What does the pelvis rolling backwards usually indicate during hip abduction MP?

use of hip flexion strategy to achieve abduction

What does the hip extension movement pattern assess?

patient’s ability to stabilize trunk and execute proper firing pattern of hip extensors in open chain

Position of patient duirng hip extension MP?

prone, legs straights, arms resting at side, spine in neutral position

Movement of patient duirng hip extension MP?

extend one hip and leg to 15-20º

extend at overpressure at ~10º to test stability

Things to look for when assessing hip extension MP?

ability to maintain neutral pelvis and lumbar for at least 10º

does trunk rotate within first 10º

able to maintain extension of knee during extension of hip

Proper muscle firing pattern during hip extension:

ipsi glute max → ipsi hamstrings → contra erectors → ipsi erectors

What are some faults of the pelvis/lumbar during hip extension MP?

anterior pelvic tilt and hyperextension of lumbar
