Muscle Energy

Question 1

isometric muscle contraction

Answer 1

origin and insertion maintained in stationary position while muscle contracted against resistance, no muscle lengthening

Question 2

isotonic muscle contraction

Answer 2

O and I approximate while maintaining constant tension, muscle shortens

Question 3

isolytic muscle contraction

Answer 3

applied counterforce > patient force, lengthening of muscle

Question 4

concentric muscle contraction

Answer 4

O and I approximate due to increasing tension, muscle shortens

Question 5

active method OMT

Answer 5

patient voluntarily performs a physician directed motion

Question 6

passive method OMT

Answer 6

patient refrains from voluntary muscle contraction and remains relaxed

Question 7

what is muscle energy

Answer 7

a direct form of OMT where patient’s muscles are used actively from a precise position in a specific direction against physician counterforce

Question 8

types of muscle energy

Answer 8

1. post-isometric relaxation
2. reciprocal inhibition
3. crossed extensor reflex
4. respiratory assistance
5. oculocephalogyric reflex

Question 9

goal of PIR

Answer 9

muscle relaxation, lengthening of muscle, a gentle contraction is initiated in agonist, followed by relaxation of agonist in refractory state in which the physician can take up the slack and lengthen the muscle to the new feather edge of the barrier
