muscle energy lab Flashcards
MET is what type of osteopathic technique?
direct
what is the end goal of MET
muscle relaxation and increased mobility
DECREASE in gamma gain
what is the patients force in MET
pure muscle contraction
respiration
use of anatomic and physiologic reflexes
where does the treatment of MET start>
at the feather edge of the restrictive barrier
where the barrier is first noted
when does MET stop?
when no further change is noted or full physiologic range of motion is obtained
what is gamma gain
increased efferent gamma motor neuron activity
due to increased neuron activity that occurs as a consequence of faulty regulation by suprasegment supervision of intrinsic and extrinsic reflex systems
what do gamma motor neurons do?
control muscle spindle activity
what are muscle spindles, what do they do
control muscle length, motion, position (proprioception)
they house 2-12 intrafusal muscle fibers that attach to extrafusal muscle fibers
type Ia and IIa afferent fibers
proprioceptive info is provided to the muscle spindle by primary annulospiral endings and secondary flower spray endings. what is the difference
primary– length and rate of stretch info
secondary - relative muscle length NO RATE of length change information
what info does the golgi tendon provide?
supplies info about stretch and tension in muscle tendons
floppy muscles
might mean decreased gamma gain
tight muscles
might be increase gamma gain
golgi tendon receptors– the receptors only transfer info about spindle length in relation to muscle length …. but what can’t they do?
they have no way to send info to the spindle about actual muscle length
soooo the muscle length may be maintained in a shortened position by increased gamma gain because decreased tension is being reported to the spindle
what is isometric MET
means the counterforces of patient and doctor equal each other and no length change is permitted by the muscle
crossed extensor relfex
when the flexor group of one rgion of the body is contracted , the contralateral flexor relaxes and the contralateral extensor tightens
reciprocal inhibition
agonist muscle contraction produces antagonist relaxation because of central nervous system patterning
what is post-isometric relaxaiton
the refractory period after a controlled muscle contraction during which proprioceptive and nociceptive feedback is absent
allowing the muscle to be passively stretched without stimulating the myotatic reflex
what could you use on a patient that has an acute burn, cellulite or injury that does not allow them to be touched without significant discomfort
using crossed extensor reflex MET on the opposite side
how does MET enhance lymphatic and venous circulation and reduce edema and tissue congestion
because muscle contraction pumps fluid through the body
absolute contraindications for MET
absence of SD
lack of pt consent or cooperation
young child that cannot comprehend
coma-unresponsive
what does the patients contractile force accomplish in the course of met
MET works by causing stretch signal to be sent to the muscle spindle from its receptors during controlled contraction
simultaneously contracting against a force while also controlling length of muscle distracts the muscle spindle receptors with information about changing tension and length that is not actually happening
this allows muscle to return to normal length and range of motion without causing reflex shortening of hypertonic muscle s
pt pushes in what direction?
into EASE
when the patient does the osteopathic salute, what is going on?
instruct the patient to contact the back of their neck with their hand that corresponds to the side of the rotation
so if the dignosis is T9 NSLRR put their RIGHT hand on the back of their neck
understand the final corrective motion applied by the physician to complete MET
place back in neutral
