◉ Condyloid or ellipsoidal joint. Answer: Characterized by motion in
two planes.
◉ Pathological end-feel. Answer: Always classified as empty.
◉ Closed kinetic chain (CKC) motion. Answer: Characteristics
include joints just proximal to the fixed segment moving in a
predictable manner, promotion of joint stability, and decreased
shear forces.
◉ Function of ligaments. Answer: Do not connect tendon to bone.
◉ Gliding. Answer: Occurs when one joint surface moves parallel to
the plane of the adjoining joint surface.
◉ Closed packed positions of synovial joints. Answer: Best
characterized by maximal joint congruency and minimal gliding
between articular surfaces.
,◉ Convex-concave principle. Answer: States that if a convex surface
moves on a concave surface, the roll and glide occur in opposite
directions.
◉ Kinematics. Answer: Associated with motion of a body or segment
without regard to the forces that produce motion.
◉ Arthrokinematics. Answer: Concerned with gross bony motions.
◉ Rotary motion. Answer: The farther the distance from the axis of
motion, the greater the velocity of that point.
◉ Adduction. Answer: Associated with movements of a segment
closer to the midline of the body.
◉ Goniometry. Answer: Useful in quantifying translatory motion
between adjacent bony segments.
◉ Closed kinematic chain motions. Answer: Occur when the distal
segment is fixed and the proximal segments move.
◉ Motion about the x-axis. Answer: Takes place in the sagittal plane.
◉ Motion about the y-axis. Answer: Takes place in the frontal plane.
,◉ Z-axis. Answer: May also be referred to as the superior-inferior
axis.
◉ Velocity of rotary motion. Answer: Best expressed in
degrees/second.
◉ Excessive force source. Answer: May retard joint motion.
◉ Insufficient force source. Answer: May promote instability.
◉ Perpendicular distance from force vector. Answer: Referred to as
the moment arm.
◉ Shoulder abduction exercise recommendation. Answer: Move the
cuff weight further distal and perform the activity in a side-lying
position.
◉ Newton's First Law of Motion. Answer: A body at rest will remain
at rest.
◉ Newton's Second Law of Motion. Answer: Acceleration is directly
proportional to the net force applied to a body.
, ◉ First class lever systems. Answer: The axis of rotation is located
between the force and resistance arms.
◉ Torque imposed by 5-pound weight. Answer: Greatest at 90°.
◉ Normal force vector. Answer: Primarily responsible for producing
compression.
◉ Cosine of theta calculation. Answer: Divide the adjacent side by
the hypotenuse.
◉ Reducing weight effect on a joint. Answer: A clinician could
recommend aquatic therapy.
◉ Center of gravity of a body. Answer: The theoretical point around
which the mass of the object is balanced.
◉ Center of gravity of the adult body. Answer: Anterior to the border
of the 11th thoracic vertebra.
◉ Archimedes' principle. Answer: A body submerged in a liquid is
buoyed up by a force equal to the weight of the liquid displaced.
