Muscle Energy- Keagan

Question 1

4 types of muscle motions
Active, passive, inherent, physiological

Answer 1

Active- patient move
Passive- doc move patient
Inherent- spontaneous motion of every cell, organ, system (ex. Respiration)
Physiological- changes in position of body structures

Question 2

Concentric muscle contraction

Answer 2

Bring origin closer to insertion

Bicep curl up

Question 3

Eccentric

Answer 3

Origin away from insertion

Drop weight down- bicep

Question 4

Isolytic muscle contraction

Answer 4

Heavy weight overcome muscle contraction

Can’t curl 100 lbs

Question 5

Isotonic muscle contraction

Answer 5

Muscle tone stays same- length changes

Curl 25 lbs

Question 6

Isometric muscle contraction

Answer 6

Hold weight still

Question 7

Muscle spindle vs golgi tendon organ

Answer 7

Muscle spindle
-located in muscle bellies
- innervated by Ia and II afferent fibers
- respond to muscle stretch
OMT aims to reduce firing of muscle proprioreceptors to decrease hypertonicity

Golgi tendon organ
- located in tendons
- innervated by Ib afferent fibers
-respond to increased tension by causing reflexive muscle relaxation
OMT aims to activate GTOs to produce muscle relaxation

Question 8

Names of short and long restrictions

Answer 8

Short restrictor- monoarticular muscles (maintain Type II segmental dysfxns)

Long- polyarticular muscle (maintain Type I group dysfxns)

Question 9

MET for muscle relaxation

Answer 9

Post-isometric relaxation

After contraction, NM in refractory state, passive stretching performed, take up slack, activate GTO= inhibits muscle contraction

Question 10

MET for restoration of joint motion

Answer 10

Joint mobilization using muscle force

Use muscle contractions to free up restricted motion at joint

Question 11

What does respiratory assistance MET do

Answer 11

Improves physiology with voluntary respiratory motion

Fulcrum applied by doc to places that have increased motion during respiration

Question 12

When you look left while driving and steer left this is due to what reflex

Answer 12

Oculocephalic reflex MET

Cause reflex muscle contractions using eye motions

Question 13

MET that lengthens muscle shoprtened by spasm

Answer 13

Reciprocal inhibition

Contraction of antagonist of hypertonic muscle results in reflex of spastic muscle

Question 14

Sherrington second law

Answer 14

When muscle receive interaction, its antagonist will receive inhibitory innervation

Question 15

Crossed extensor reflex

Answer 15

If left ham hypertonic
-contract right quad
-signals cords to spinal cord to relax left ham

Contract opposite side antagonist of hypertonic muscle

Question 16

What MET reestablishes normal muscle tone and strength in a weakened muscle by hypertonicity of opposing group

Answer 16

Isokinetic strengthening

Ex.hypertonic bicep= weak tricep
—> apply force to tricep as patient is moving

Question 17

Isolytic lengthening

Answer 17

Lengthen muscle shortened by contracture/fibrosis

Move muscle back and forth as patient contracts it- relaxes and lengthens muscle
