what is the human movement system known as
compromises the muscular, skeletal and nervous systems.
what two regions can the hms be classified into
upper kinetic chain and the lower kinetic chain
what does the upper kinetic chain consist of
shoulders, elbow, wrist and hand
what can the lower kinetic chain consist of
hip, knee, ankle and foot.
what does HMS stand for
human movement system `
what can happen if the upper and lower kinetic chain are not aligned
can cause dysfuntion
what are postural distortion patterns
predictable patterns of muscle imbalances
what can a lack of structural integrity result in
muscle imbalances, altered force couple relationships, altered osteokinematics and arthrokinematics.
what is force couple relationships
the synergistic action of multiple muscles working together to produce movement around a joint
what is osteokinematics
movement of a limb that is visible
what are arthrokinematics
the description of joint surface movement; consist of three major types: roll, slide and spin.
what chapter of the nasm cpt course can you identify more of static postural distortions and altered movement patterns
chapter 12
what can cause muscles imbalances
reciprocal inhibition, synergistic dominance, and osteo- and arthrokinematics dysfunction.
what is reciprocal inhibition
the activation muscle agonist leads to the relaxation of the antagonist muscle during a contraction
what is synergistic dominance
A synergist muscle assists the agonist muscle or “primary mover” for a specific action at a joint. For example, inhibition of the gluteus maximus may lead to synergistic dominance of the biceps femoris during hip extension.
what is osteo- and arthrokinematics dysfunction.
Examples: Limited inferior glide of the femoral head (arthrokinematic dysfunction) can lead to reduced abduction (osteokinematic dysfunction) of the hip.
Reciprocal inhibition
When an agonist receives a signal to contract, its functional antagonist also receives an inhibitory signal allowing it to lengthen.
Altered reciprocal inhibition
Occurs when an overactive agonist muscle decreases the neural drive to its functional antagonist.
Overactive
When elevated neural drive causes a muscle to be held in a chronic state of contraction.
Underactive
When a muscle is experiencing neural inhibition and limited neuromuscular recruitment.
what is the difference between osteo and arthrokinematics dysfunctions
osteokinematics describes how the bones and joints are moving through a ROM. and osteo refers to joint motion we can see such as flexion, extension, abduction, adduction, or rotation of the body.
muscle spindle
sensory receptors sensitive to change in length of the muscle and the rate of that chage
central nervous system
a division of the nervous system that includes the brain and spinal cord
what is the golgi tendon organ
is located within the point where the muscle and the tendon meet. A specialized sensory receptor located at the point where skeletal muscle fibers insert into the tendons of skeletal muscle; sensitive to changes in muscular tension and rate of tension change.
