-
What aspect of exercise is controlled during isokinetic exercise?
The velocity of the limb movement.
-
Valsalva’s maneuver should be avoided during resistance exercise because?
There is an abrupt increase in arterial blood pressure.
-
To initiate quick burst of force, plyometric training uses?
The stretch reflex
-
When trying to improve stability in and around a joint, closed chain exercise maybe more beneficial than open chain because?
Closed chain stimulates mechanoreceptors in axial loading.
-
An individual requires less effort to control a load eccentrically than concentrically because?
Fewer motor units firing
-
More _____ is produced with eccentric contractions than with concentric contractions.
Force
-
During muscle stretching, a sustained stretch is recommended for 30 to 60 seconds because?
Allows the GTO to fire.
-
During a stretch of the latissimus dorsi, you would stabilize where?
Lateral thorax
-
When using the hold relax technique to stretch a muscle, you would have the patient?
Isometrically contract the muscle
-
What is the plastic change of connective tissue?
Permanent lengthening
-
An effective way to lengthen a tight muscle, particularly if the tight muscle is painful or is in the early stages of healing is by?
Agonist contractions
-
A passive procedure to increase mobility.
Mobilization
-
If the moving bone is convex, gliding is in the _____ direction.
Opposite
-
A capsular patter restriction of the shoulder would have the greatest loss of motion in what movement?
External rotation
-
Grade I and II for joint mobilization are primarily to treat what?
Pain and muscle spasms
-
A large amplitude rhythmic oscillation performed up to the limit and stressed into the tissue resistance is what grade of dosage?
Grade III
-
Separation of joint surfaces at right angles during joint mobilization is called?
Distraction
-
The resting position of this joint is flexed 25 degrees.
Knee
-
The resting position of this joint is slight flexion.
Finger
-
The resting position is abducted 55 degrees, adducted 30 degrees, and rotated so the forearm is in the horizontal plane.
Shoulder
-
The resting position is flexed 70 degrees and supinated 10 degrees.
Elbow
-
The resting position is flexed 30 degrees, abducted 30 degrees, and slight external rotation.
Hip
-
Restriction of motions are proportional relative to each other suggesting joint capsule tightness.
Capsular pattern
-
Motions that occur between joint surfaces and the distensibility in the joint capsule.
Joint play
-
Which ligament becomes taut in open chain knee flexion?
PCL
-
At what flexion angle is compression of the posterior aspect of the patella greatest?
60 degrees
-
The tissue used to surgically reconstruct the ACL using an autogenous patellar tendon graft goes through a process of:
Avascular necrosis in the first 3 weeks
-
Closed chain exercises can begin for a patient after a meniscus repair after _____ weeks.
8 weeks
-
Movement of bones due to the shape of the bony surface.
Arthrokinematics
