CES Final Exam
Neuromuscular efficiency ......ANSWER......The ability of the
neuromuscular system to allow agonists, antagonists, synergists, and
stablilzers to work synergistically to produce, reduce, and dynamically
stabilize the kinetic chain in all three planes of motion.
Posture ......ANSWER......The independent and interdependent
alignment (static posture) and function (transitional and dynamic
posture) of all components of the human movement system at any
given moment; controlled by the central nervous system.
Structural efficiency ......ANSWER......The alignment of each segment of
the human movement system (HMS), which allows posture to be
balanced in relation to one's center of gravity.
Functional efficiency ......ANSWER......The ability of the neuromuscular
system to recruit correct muscle synergies, at the right time, with the
appropriate amount of force to perform functional tasks with the least
amount of energy and stress on the human movement system.
,Cumulative injury cycle ......ANSWER......A cycle in which an injury will
induce inflammation, muscle spasm, adhesion, altered neuromusclular
control, and muscle imbalances.
Movement impairment syndrome ......ANSWER......Refers to the state in
which the structural integrity of the human movement system (HMS) is
compromised because the components are out of alignment.
Altered reciprocal inhibition ......ANSWER......The process whereby a
tight muscle (short, overactive, myofascial adhesions) causes decreased
neural drive and therefore optimal recruitment of its functional
antagonist.
Synergistic dominance ......ANSWER......The process by which a synergist
compenstates for a prime mover to maintain force production.
Lower extremity movement impairment syndrome
......ANSWER......Usually characterized by excessive foot pronation (flat
feet), increased knee valgus (tibia externally rotated and femur
internally rotated and adducted or knock-kneed), and increased
movement at the lumbo-pelvic-hip-complex (extension or flexion)
during functional movements.
Upper extremity movement impairment syndrome
......ANSWER......Usually characterized as having rounded shoulders and
a forward head posture or improper scapulothoracic or glenohumeral
kinematics during functional movements.
,Lengthening Techniques ......ANSWER......2nd phase in the Corrective
Exercise Continuum is to lengthen those overactive or tight
neuromyofascial tissues.
Lengthening ......ANSWER......refers to the elongation of mechanically
shortened muscle and connective tissuenecessary to increase range of
motion (ROM) at the tissue and joint.
2 most common methods of stretching: ......ANSWER......Static
stretching
Neuromuscular stretching
Static stretching ......ANSWER......Combines low force with long duration
using autogenic inhibition. This form of stretching allows for relaxation
and concomitant elongation of muscle. To perform static stretching, the
stretch is held at the first point of tension or resistance barrier for 30
seconds. Performed solo
Neuromuscular stretching ......ANSWER......commonly called
proprioceptive neuromuscular facilitation,or PNF involves taking the
muscle to its end ROM (point of joint compensation), actively
contracting the muscle to be stretched for 7 -15 seconds, then passively
moving the joint to a new end ROM and holding this position for 20-30
seconds.
, Recurrent inhibition ......ANSWER......A feedback circuit that can
decrease the excitability of motor neurons via the interneuron called
the Renshaw cell.
Stretch reflex ......ANSWER......A muscle contraction in response to
stretching within the muscle.
Static stretching is characterized by: ......ANSWER......The elongation of
neuromyofascial tissue to an end-range and statically holding that
position fora period of time.
Maximal control of structural alignment
Minimal acceleration into and out of the elongated (stretch) position.
Neuromuscular stretching is (NMS) characterized by:
......ANSWER......Taking the muscle to its end ROM (point of joint
compensation)
Active contraction of the muscle to be stretched
Passively (or actively) moving to a new end ROM
Statically holding new position for 20-30 seconds and repeating 3 times.
Neuromuscular stretching ......ANSWER......Is a technique that involves a
process of isometrically contracting a desired muscle in a lengthened
position to induce a relazation response on the tissue, allowing it to
further elongate. Requires the assistance of another person.
