What are some contraindications for using diathermy?

Contraindications for using diathermy include the presence of metal implants, such as pacemakers or joint replacements, as the heat generated can interfere with their function. Other contraindications include pregnancy, areas with active bleeding or infection, malignancies, and conditions characterized by impaired sensation. Additionally, diathermy should be avoided in patients with thrombophlebitis or those who have recently undergone surgery in the treatment area. Always consult a healthcare professional before proceeding with diathermy treatment.
