Normal Gait (Chen) Flashcards
this muscle plays in important role in keeping the body standing straight within the line of gravity, preventing it from falling forward
gastrocnemius
these muscles are the active stabilizers of the hip joint, and help maintain coronal plane balance
gluteus maximus and gluteus medius
this ligament passively stabilizes the hip joint
iliofemoral ligament
these muscles actively stabilize the knee joint
quadriceps
these ligaments passively stabilize the knee joint
posterior capsule (ligaments)
this muscle actively stabilizes the ankle joint
gastrocsoleus
*there is no passive stabilization of the ankle - therefore, standing is passive except for plantarflexion
At average velocity, the stance phase is ~____% of the gait cycle
60%
*why not 50%, he asks in his notes? the question was never directly answered but may have something to do with double support time required - that is, when the heel of one foot is on the ground at the same time that the toes of the other foot are “stepping off”
major complication of damage to the syndesmosis (ie, the connective tissue that joins the tibia to the fibula distally), sometimes appearing decades later
post-traumatic osteoarthritis
neurological complication of crutches that generally resolves spontaneously in about 8-12 weeks
“crutch palsy” - compression of the brachial plexus
compression of what nerve may occur with overtight casting of a broken ankle? what muscles would be affected?
peroneal nerve; dorsiflexors (tibialis anterior) and everters (peroneus longus) would be affected
Which of the following would not be part of a differential for tingling and numbness of the anterior ankle and dorsal surface of the foot?
A. Compartment syndrome
B. DVT
C. Tibial nerve compression
D. Peroneal neuropathy
C
A patient exhibiting “foot drop” may be suffering from nerve damage to what muscle that is innvervated by the peroneal nerve?
tibialis anterior
A patient is found to have a hypercoagulable state which led to development of deep venous thrombosis, and was placed on anticoagulants. Following an error in dosing, the patient developed severe belly pain, thigh weakness, and was unable to get out of bed.
PE: Quadriceps 0/5.
CT: large retroperitoneal hematoma
What is the diagnosis?
femoral neuropathy
*patient will push on their knee using their posterior capsule, MCL and ACL to provide support and walk.
Which of the following would be the LEAST helpful intervention in a person with a drop foot?
A. Ankle foot orthosis
B. Stetching exercises
C. Walking boot
D. High top shoes
E. 3 wheel walker
