INCOMPLETE Agents - 4 - Electrical Currents for Muscle Contraction

neuromuscular electrical

NMES stands for _________________ stimulation

functional electrical

FES stands for _________________ stimulation

electrical muscle

EMS stands for _________________ stimulation

NMES

____ is for innervated muscle

FES

____ is for innervated or denervated muscle

EMS

____ is for denervated muscle only

NMES

the goal of ____ is strength and reeducation

FES

the goal of ____ is to facilitate or enhance functional movement

EMS

the goal of ____ is to preserve muscle while nerve regenerates, controversial

NMES

we spend most of our time in this course with which type of estim:

electrical currents, innervated

NMES is the use of ___________ to produce muscle contractions in _________ muscle

T

T/F: NMES is highly adaptable

F; 10% of people don’t tolerate estim

T/F: everyone can tolerate estim well

action potential propogation

___________________ is what causes the nerves to become depolarized and then muscle fibers innervated by them contract

smaller type 1, larger

_________ muscle fibers are activated before _______ muscle fibers

contractions (this is debated though)

NMES should be used with patient performing ___________ to maximize strength gains

disuse

NMES is very effective at strengthening fibers that are weak secondary to _______

physiologically initiated

(physiologically initiated/electrically stimulated) contraction : slow twitch type 1 first

electrically stimulated

(physiologically initiated/electrically stimulated) contraction : fast twitch type II first

physiologically initiated

(physiologically initiated/electrically stimulated) contraction : contraction force is low

electrically stimulated

(physiologically initiated/electrically stimulated) contraction : contraction force is high

physiologically initiated

(physiologically initiated/electrically stimulated) contraction : speed of contraction is slow

electrically stimulated

(physiologically initiated/electrically stimulated) contraction : speed of contraction is fast

physiologically initiated

(physiologically initiated/electrically stimulated) contraction : fatigue resistant

electrically stimulated

(physiologically initiated/electrically stimulated) contraction : fatigues quickly

physiologically initiated

(physiologically initiated/electrically stimulated) contraction : atrophy resistant

electrically stimulated

(physiologically initiated/electrically stimulated) contraction : atrophies quickly

physiologically initiated

(physiologically initiated/electrically stimulated) contraction : recruitment is asynchronous

electrically stimulated

(physiologically initiated/electrically stimulated) contraction : recruitment is synchronous

motor unit recruitment

there are often big gains at the beginning of a program because of increased _______________________

T

T/F: in initial weeks after a surgery or injury, the progress lost isn’t as much from atrophy as it is the muscles forgetting how to work together

muscle fiber size, motor unit recruitment

muscle strengthening can happen via increased _____________ or improved ______________

1

muscle re-education and activation is sometimes called phase ___

2

NMES for strengthening is sometimes called phase ___

T

T/F: you have to activate a muscle before you can strengthen it

II

NMES has more effect on type ____ fibers
