russian stimulation

Question 1

russian stimulation is also known as

Answer 1

medium frequency burst alternating current

Question 2

what elctrotherapy is characterized by bust pulses or intermittent pulses

Answer 2

russian current

Question 3

differences of russian from the other currents

Answer 3

it is painless
the mscle contraction can generate 30 perc more force
muscle strength of 40 perc can be achived

Question 4

duration

Answer 4

10 minutes

once daily for 3-6 months

Question 5

characteristics of russian current

Answer 5

they use polyphasic sinusodial waveform
2500hz
maximum current amplitude is 100ma and 70 for clinical use 
burst freq 50
burst duration 10

Question 6

what are the electrode placements in russian

Answer 6

parallel to the direction of muscle fibers

Question 7

time delay switch modes for russian stimulation

Answer 7

synchronous mode
reciprocal mode
overlapping mode

Question 8

sensory nerve fibers and motor nerve fibers effects respectively

Answer 8

moderate prickling sensation and tetanic muscle contraction

Question 9

therapuetic effects

Answer 9

to improve muscle strength .. the amplitude is… tetanic muscle 50-70 hz ..150-200 us
apply in isometrics in diff rom the 10 50 10 rule is applied

to reduce muscle spasm .. same for hz but 50-175 us
provide brief isometric contractions same amplitude for muscle strength

to reduce oedema…… small visible muscle contraction
35-50 freq .. 400 us duration
treatment time is 0-15 min

Question 10

what is the carrier frequency of russian

Answer 10

2500 hz

Question 11

duty cycle

Answer 11

Duty cycle is the proportion of on-time to the summation of both the on
and off time expressed as percentages
its 50 perc with russian current

Question 12

ramp up and ramp down is set for how many sec

Answer 12

1-2

Question 13

widely used clinical prorcol with russian is

Answer 13

10 50 10

Question 14

physiological effects depends on what

Answer 14

total number of bursts delivered per sec

russian current has a capacity to depolarize

Question 15

the russian current depolarizes what fibers

Answer 15

sensory and motor

Question 16

physiological and therapuetic properties

Answer 16

medium freq burst alternating current flow
depolarization of peripheral sensory and motor nerves
activation of type 2 motor unit
efficient muscle contraction
muscle stengthening

Question 17

leave a rest period btw contractions to prevent what

Answer 17

fatigue

use the 10 50 ratio

Question 18

to achieve the most optimal muscle contraction what should be used in electrode placements

Answer 18

motor points

Question 19

what is the most suitable placement for the russian stimulation

Answer 19

bipolar

Question 20

only msucle tissue should be stimulated if not what happens if other tissues are stimulated

Answer 20

uncomfortable feeling

Question 21

the farther the elctrodes

Answer 21

the deeper the penetration

Question 22

when is synchronization used

Answer 22

where single application to large muscle group is insufficient

Question 23

when is reciprocal stimulation used

Answer 23

to stimulate the antagonist muscle to save time

used in proproception training

Question 24

whats the main indication for russian current

Answer 24

increase muscle strength
