Exam 1 - Pathologic Gait

Terms in this set (19)

What is a likely cause of knee HE in loading response?
Weakness of quads
What is a likely cause of forward lean of the trunk in terminal stance?
Limited hip extension ROM
Decreased dorsiflexion can cause HE of the knee in which phase of gait?
Mid-Stance
If you can't DF the ankle, what are common compensations to reduce foot drag during swing phase?
Excessive knee/hip flexion
If you have hypertonicity of the quads, what will a likely gait deviation of the knee will occur during initial swing?
Limited flexion of the knee
A person with a hamstring contracture will present with which gait deviatino during MID-STANCE?
Excessive DF (opposite of knee HE/plantar flexion example, I think)
What is a likely gait deviation from calf weakness during pre-swing?
No heel off
Patient presents with PF weakness. What gait deviation are we most likely to see during terminal stance?
Excessive DF of the ankle.
What intervention is most likely to reduce the occurrence of drag of the toes in initial swing?
PF strengthening (to increase push off capacity)
What intervention will decrease the backward lean of trunk during loading response?
Glute max strengthening
What are the 4 mechanisms of pathological gait?
Impaired motor control, abnormal ROM, impaired sensation, pain
What is elastic contracture?
Results from inactivity or increased stiffness of bulky tissues
What is rigid contracture?
Muscle shortness of soft tissue scarring.
What is antalgic pain?
Gait deviation due to pain
What is past retract?
Visible forward them backward movement of the thigh in terminal swing.
What causes the hip to hike?
Unlevel pelvis or leg length discrepency
What is trendelenberg gait?
weakness of the hip ABDs which causes contra-lateral hip drop of more than 5 degrees in stance phase of the reference limb
Which sort of rotation of the hip is not considered a major deviation?
Excessive backward rotation
Why do people lean backward during weight acceptance?
To decrease the demand of the glute max (hip extensors). When limiting hip flexion, there is less of a need for the glute max (extensors) to have to counteract that flexion torque. Also moves GRF posterior to hip which induces and extension torque (GRF are doing work for the glutes).
