What is the first step in a procedure designed to decrease muscle activity?

Instruct the patient to perform exercises

Place electrodes close together and set sensitivity low

The first step in a procedure designed to decrease muscle activity involves placing electrodes close together and setting the sensitivity low. This technique is essential in modalities like electrical stimulation, where the goal is to modulate muscle activity or reduce muscle spasms. By positioning the electrodes closely, you can create a more localized effect on the muscle, allowing for better control over stimulation without overwhelming the tissue. Setting the sensitivity low helps ensure that the stimulation does not activate surrounding muscle fibers unnecessarily, aligning with the objective of decreasing muscle activity.

Other options may involve promoting engagement or activity in the muscle rather than decreasing it, which is not suitable for this context. Therefore, initiating the process with electrode placement and sensitivity adjustments is crucial to achieving the desired outcome of reduced muscle activity effectively.
