A patient with multiple fractures presents with vertigo and dry skin. Which physical agent would be most beneficial?

In the case presented, the combination of multiple fractures, vertigo, and dry skin suggests a need for treatments that can provide both warmth and moisture to the skin while potentially aiding in relaxation and improving circulation. Paraffin as a physical agent is particularly beneficial in this scenario because it delivers moist heat, which can help with pain relief and promote healing of soft tissues around the fractured areas.

The heat from paraffin can also enhance blood flow to the skin, which might be beneficial for someone experiencing dryness, as it can improve skin hydration. Additionally, the warm, soothing quality of paraffin can help reduce muscle tension and alleviate discomfort, which is important for a patient dealing with multiple fractures.

Other modalities, while useful in certain situations, do not address the moisture needs of dry skin or may not adequately provide the same soothing warmth. For example, hot packs provide dry heat but do not add moisture, functional electrical stimulation is more focused on muscle activation rather than relaxation or skin benefits, and contact ultrasound is generally used for deeper tissue healing rather than for addressing skin conditions or promoting relaxation. Thus, paraffin is the most appropriate choice given the specific needs of this patient.
