Orthotic fitter exam study guide Correct
answers latest update
What muscles make up the hamstrings
semimembranosus, semitendinosis, bicep femoris
Chondromalasis patella may be caused by
over pronated foot, weak vastus medialis obliquis, weak gluestus medius
What is Bursistis
Inflammation of the bursa, causing swelling and pain
What are bursa
fluid filled sacs between tissues
What is eccentric
controlled movement in which you move toward an opposing force, rather than away. Lengthening of
the muscle
Example of eccentric muscle contraction
lowering a weight, walking down stairs
What is apropulsive gait
foot drop, partial foot amputation or soft tissue dysfunction
Proprioception rehabilitation can on occur
during controlled motion when weight bearing
Normally____, when torn loose by a sudden ____, seldom break in the middle rather, they _____
away from the _____ at the _____
Normally tendons, when torn loose by a sudden force, seldom break in the middle rather, they pull
away from the bone at the end
What is antalgic gait
a gait in which the stance phase is shorter than the swing phase. It is a good indicator of weight
bearing pain
What is Ataxic gait
an unsteady, uncoordinated walk with a wide base and the feet thrown out, coming down first on the
heel and then the toes with a double tap
What is the popliteal fossa
cavity posterior to the knee
What is the function of the skeletal system
, to provide a flexible foundation and manufacture red blood cells
What is a shoulder joint
ball and socket joint, muscle dominated joint and can move in all planes
Joint stability requires
adequate strength, appropriate ROM and adequate proprioception
What is a closed kinetic chain
a series of connected joints in which the distal segment is in fixed, weight bearing position.
Orthotics can aid in
eccentric muscle activity, reactive muscle activity and concentric muscle activity
What is concentric
muscle activation (contraction) that causes tension on your muscle as it shortens, generating enough
force to move an object
Example of concentric muscle contraction
Bicep curl
What is double-step gait
a gait in which there is a noticeable difference in length/timing of alternate steps
What are sacomeres
overlapping work units within muscle structures
How can the posterior cruciate ligament can be injured
excessive ankle dorsiflexion and a so called dash-board injury.
What is Chondromalasis of the patella
roughening of the articulating surface of the patella
What is an articulation
forms a joint
What is a collateral ligament
any ligament running along the medial/lateral sides of a joint
The foot/ankle complex serves what 3 purposes
flexible adaptor to the terrain, flexible stabilizer during ROM and a rigid lever arm to propel off the
terrain
