A physical therapist incorporates electrical stimulation as part of the plan of care for a patient rehabilitating from a lower extremity injury. Which of the following recommendations would be LEAST effective to minimize electrode resistance?

Using small electrodes tends to create greater resistance when compared to larger electrodes. This is because smaller electrodes have a smaller surface area that is in contact with the skin, leading to higher current density and therefore greater resistance. Increased resistance can result in reduced effectiveness of electrical stimulation, as the electrical current has a harder time penetrating the skin barrier effectively.

Maintaining a well-moistened sponge interface, ensuring even and firm contact with the skin, and removing hair are all practices that directly reduce electrode resistance. A high level of moisture in the sponge interface helps to conduct electricity more efficiently, while even and firm contact ensures that the current flows uniformly across the electrode. Removing hair eliminates additional resistance that could occur at the skin surface. Therefore, focusing on the use of small electrodes is less effective in minimizing electrode resistance compared to the other techniques mentioned.
