Altering the stimulus's intensity is not a way muscle contractions can be graded.

<h3>A graded contraction is what?</h3>

In a graded contraction, you would send the muscle a series of nerve impulses that were higher frequency when you wanted to generate a stronger force. The propagation of impulses would then require more axon brush nerve terminals. An established number of muscle fibers are controlled by each axon brush nerve terminal.

<h3>What does grading mean in terms of measurements of muscular contraction?</h3>

Measurement of muscular strength in persons with a known or suspected neurological disease, such as a stroke, is frequently done using muscle strength grading. However, it can be utilized to help distinguish between real muscular weakness and imbalance or endurance issues in anyone who complains of muscle weakness.
