The term that describes the manner in which electricity is utilized to create a therapeutic effect is "modality." In the context of electrotherapy, modalities refer to specific techniques and methods employed to treat various conditions through the application of electrical energy. This can include different forms of electrical stimulation, such as TENS (Transcutaneous Electrical Nerve Stimulation) or EMS (Electrical Muscle Stimulation), each designed to achieve distinct therapeutic outcomes like pain relief, muscle rehabilitation, or improved circulation.

Current, voltage, and resistance are essential concepts in the study of electricity but do not encapsulate the therapeutic applications directly. Current refers to the flow of electric charge, voltage measures the potential difference that drives this flow, and resistance indicates how much a material opposes the flow of electricity. While these concepts are fundamental to understanding how electrotherapy works, they do not specifically describe the methods or techniques utilized for therapeutic purposes. Therefore, "modality" is the clear choice for this question.
