Which of the following best describes the current amplitude necessary when neuromuscular electrical stimulation (NMES) is used to increase ROM through muscle activation?
A) An amplitude that is greater than 80% of the maximal voluntary isometric contraction
B) An amplitude that elicits fasciculations, but below the level of tetany
C) An amplitude that elicits muscle contractions capable of moving the joint through the desired ROM
D) An amplitude that is just below the motor threshold

Question

Quizplus · Accepted Answer

The current amplitude necessary when NMES is used to increase ROM through muscle activation should elicit muscle contractions that are capable of moving the joint through the desired ROM. This means that the amplitude should be high enough to produce some movement but not so high that it causes discomfort or fatigue in the patient.
