during the early stages of development of SCS, 3 things emerged:
-it was crucial to bring the body part back to the neutral position very ...
-decreased time in position of comfort from 20 minutes to ... seconds
-discovered myofacial ... associated with specific somatic dysfunctions.
-slowly
-90 seconds
-tender points
strain counterstrain:
-both ... and ... away from restriction of the barrier
passive
indirect
Korr 1975-neurological model
-decreased joint mobility or decreased range of motion determines ...
-muscle's can function to "..." or slow down joint motion e.g. slowing the swinging limb during the step cycle
somatic dysfunction
brake
a sensory nerve ending within muscle is called...
muscle spindle
what 4 components make up the muscle spindle?
alpha motor neurons
gamma motor neurons
type 1a sensory
type 2 sensory
on the surface of the muscle, there are what kind of muscle fibers?

within the spindle, there are what kind of muscle fibers?
extrafusal muscle fibers
intrafusal muscle fibers
when a muscle is stretched, it is ...

in response to a stretch, the muscle ...
sensed
contracts
(tapping of a tendon that inserts an extensor muscle in the front of the thigh into the lower leg):
which neuron senses the stretch?
type 1a sensory neurons
which neurons carry impulses back to the same muscle causing it to contract? (the leg straightens)
alpha-motor neuron
some of the branches of the 1-a axons synapse with ... in the spinal cord. these in turn synapse with motor neurons leading back to the ... muscle, a flexor in the back of the thigh.
inhibitory interneurons
antagonistic
still, other branches of the 1-a axons synapse with interneurons leading to brain centers, e.g., the ... that coordinates body movements
cerebellum
what causes contraction of the intrafusal muscle at each end?
-makes spindle more sensitive to stretch
-thereby influencing muscle tone
-thereby influencing muscle resting length
gamma motor neurons
1a and 2 afferents signal ... change, i.e. slow stretch - measuring length
static
1a afferents alone signal ... change - i.e., rate of change of muscle length - impt. behind theory of strain counterstrain
dynamic
gamma d - increases dramatically the ... response - rapidly change in length
dynamic
gamma s - influences the .. response
static
normal conditions finds gamma-muscle spindle output ...
continuous
positive signals to spinal cord ... rate of firing
increases
negative signals to spinal cord ... rate of firing
decreases
it is thought that when there is a rapid (really super quick) change in muscle length it may cause the antagonist to overreact to the stimuli and "hypershorten". This resets the normal muscle tone to hypertonicity via the overactive ... system
gamma
gamma control works well when there is a ..., ... change in muscle length
slow, steady
so it has been hypothesized that after shutting down the muscle spindle by putting the muscle in a passive hypershortened position, the slow return to ... will reset the muscle to normal resting length and tone
neutral
putting the body part into a position of greatest comfort and least pain and holding there for 90 seconds:
-resets ...
-allows washout of ...
propioception
metabolic waste
guidelines:
-treat the most ... first
-don't do more than # or # in one session - wait 3-4 days between sessions
-if "crooked" look to the ... of the curve first
-establish ... scale
severe
5 or 6
apex
tenderness
you may feel the tender point "..." away

you may feel ... as the tissues release

recheck tenderpoint after return to neutral (#%)
melt
pulsations
70%
use the terms ... (flexion) and ... (extension) for movements of the ankle
plantar flexion
dorsiflexion
