Closed Kinematic Chain:
A. Pelvic on Femoral
B. Femoral on Pelvic
Pelvic on Femoral
An example of pelvic on femoral
bending over to pick up a flower pot
Pelvic on Femoral what kind of Frontal pane movement?
Abduction/ Adduction
Pelvic on Femoral is a _____ couple between hip _____ and _____ _______
FORCE couple between hip flexors and back extensors
What movement do you do if you want to stretch your hip flexors
Posteriorly tilt pelvis
Name the 5 hip ADDuctors
- pectineus
- adductor longus, adductor brevis
- gracilis
- adductor magnus
Which muscle performs sagittal plane function
Adductor Longus
Hip muscle action of Adductor Longus
Hip Extension and knee flexion
There are NO PRIMARY Internal Rotators of the Hip : True or False
TRUE
Secondary internal rotators of the hip are:
Anterior fibers of glutues medius/ minimus
Tensor Fascia Lata
Adductor longus, brevis, pectineus and medial hamstrings
Name the hip extensor’s prime mover
Gluteus Maximus
Concentric activation of hip extension does what?
Hip Extensionnn :)
Concentric Activation (hip extensor) examples:
Sitting position to a standing position
-walking up the stairs
-jumping/ running
Femoral on pelvic- what position should you be in?
Lying on back/ lift leg
Eccentric Activation of Hip Extensor Muscles:
what position?
Going from a standing position to a sitting position
(de-accelerator/ “break”)
Hip Extensor = Posterior Pelvic Tilt.
True or False?
TRUEEE
How to Stretch Hip Extensors
Posterior Pelvic Tilt or Stand Neutral
True or false:
Hip Abduction is NOT a common action
TRUEEE
Primary Hip Abductors
Gluteus Medius & Gluteus Minimus
Secondary hip abductors
Piriformis
TFL
Sartorius
What is Abductors main function?
control of frontal plane pelvic on femoral stability during gait
What is an example of abductors main function?
Walking and in phase of gait where body weight is on a single leg. If right leg is off ground (unsupported) and left leg is supported (on ground)—> body will then move naturally/ gravity to the right side = unsupported side
what is primary source of stability in the hip
control frontal plane stability
How does Hip Abductor effect Moment Arm and Mobility
Large Moment Arm= decreased mobility
- more for stability of pelvic and abdominal region
**If a person lifts their leg off the ground, and pelvis drops to the left side as well, this indicates weakness of the ________ hip abductors
RIGHT
*** If a person lifts their right leg off the ground, the pelvis drops to the right side, this indicates Weakness of the ______ hip abductors
LEFT (Gluteus Medius)
An example of Hip Abductor Torque:
Arthritis- Left Hip = Cane on Right Hand
The 6 External Rotators:
1.) Piriformis
2.)Obturator Internus/ externus
3.) Superior Gemellus
4.) Quadratus Femoris
5.) Gluteus Maximus
6.) Sartorius
Primary external rotator:
Piriformis
