Answer 1

Strengthen
>cardiac health
Prevent mm atrophy
< spacticity
restore Fx
education/reeducation

Question 2

What differs between Estim and physiological mm contractions?(2)

Answer 2

Order of recruitment of motor units

Estim-jerky Phys-smooth

Question 3

Which nerve fibers are stimulated first in a physiological mm contraction?

Answer 3

Slow-twitch type I (smaller to larger)

Question 4

Which nerve fibers are stimulated first in an Estim mm contraction?

Answer 4

Fast-twitch type II (larger to smaller)

Question 5

What should be implemented along with Estim for mm contraction to integrate its affects?

Answer 5

Physiological mm contractions

Question 6

What 2 mechanisms stimulate mm contraction with Estim?

Answer 6

Overload principal

Specificity

Question 7

Overload principal?

Answer 7

Greater load=more str gain

Question 8

What 4 factors can be > for Estim overlaod?

Answer 8

Pulse duration
Amplitude
Electrode size
External resistance

Question 9

Specificity theory?

Answer 9

Mm contractions strengthen the specific mm fibers that are contracted

Question 10

Who does the specificity theory indicate as candidates for Estim for mm str?

Answer 10

Reduced mm str
Immobilization
Mm weakening pathology

Answer 11

50%

Question 12

What % of MVIC can still produce str gains in injured mms?

Answer 12

10%

Question 13

How do you build endurance with Estim?

Answer 13

Lower force for prolonged periods
