15 Questions
What is the purpose of the ramp in NMES?
To gradually increase the nerve fiber stimulation and initiate a comfortable contraction
Which of the following is NOT a common treatment goal of NMES?
Reducing pain
What is the typical duty cycle used in clinical NMES applications?
1:3
Which pulse parameter is responsible for determining the smoothness of the muscle contraction in NMES?
Frequency
How does increasing the intensity in NMES affect the contraction force?
Increases the contraction force by recruiting more motor units
Which of the following conditions would be a contraindication for NMES?
Cardiac pacemaker
What is a potential benefit of using larger electrode sizes in NMES?
Lower current requirements
Which of the following is NOT a common application of NMES?
Enhancing athletic performance
In NMES, what is the purpose of using a ramped pulse train?
To gradually increase muscle activation
Which muscle fiber type is primarily targeted by NMES?
Fast glycolytic (Type 2b)
What is a potential disadvantage of using NMES for an extended period?
Muscle fatigue and discomfort
Which of the following conditions would be an indication for NMES?
Spinal cord injury with paralysis
What is the primary mechanism by which NMES induces muscle contraction?
Direct depolarization of muscle fibers
Which of the following pulse parameters is primarily responsible for determining the depth of muscle activation in NMES?
Pulse amplitude
Which of the following is a potential complication associated with the use of NMES?
Skin irritation or burns
Test your knowledge on action potentials, the brief electrical signals essential for nervous system communication and muscle contractions. Learn about the depolarization of cell membranes, propagation of electrical signals, and neurotransmitter release in neurons and muscle fibers.
