Electrical Stimulation for mm contraction (Phys Agents) (1)

Electrical Stimulation for mm contraction
(Phys Agents)
Therapeutic goals of electrically induced mm contraction - CORRECT
ANSWER-Muscle strengthening
Muscle reeducation
Muscle pumping
Denervated mm

What is recruited first with muscle contraction - CORRECT ANSWER-Small, slow
twitch fibers
Fatigue resistant

What is recruited seconds when muscles contract - CORRECT ANSWER-Large, fast
twitch fibers
Fast fatiguing

When electrically (artificially) induced contraction, how does this affect motor
recruitment - CORRECT ANSWER-It is flipped
Muscles fire more synchronously

Asynchronous firing rate is with ______ mm contraction - CORRECT
ANSWER-Voluntary

Synchronous firing rate is with _______ mm contraction - CORRECT
ANSWER-Electricity

Parameters (briefly) for motor stimulation - CORRECT ANSWER-Longer pulses and
higher amp

Inconclusive evidence that Russian stimulation improves for by ______ in elite
athletes - CORRECT ANSWER-About 40 percent

This current is growing preference in current literature for e-stim strengthening.
Why? - CORRECT ANSWER-Biphasic pulsed current
(Better tolerated contractions, strong contractions, easy adjust parameters)

Parameter selections for mm contraction - CORRECT ANSWER-Pulse duration
Freq
on:off time
ramp time
current amp
