How deep can microwave diathermy penetrate tissues?

Microwave diathermy is a therapeutic application that uses microwave radiation to generate heat in body tissues. The depth of penetration is an essential factor to consider when using this treatment method, as it affects how effectively the therapy can alleviate conditions such as muscle pain and stiff joints.

The correct understanding is that microwave diathermy primarily penetrates tissues approximately 1 inch deep. This limited penetration depth is due to the nature of microwave radiation, which is absorbed more effectively by superficial tissues (like skin and subcutaneous fat) and doesn't penetrate as deeply as other forms of diathermy, such as ultrasound.

The other suggested depths, ranging from 2 inches to 4 inches, exceed the typical capabilities of microwave diathermy. This is important for clinicians to understand, as it influences treatment protocols and expected outcomes. Knowing that the effective therapeutic penetration is around 1 inch allows practitioners to target specific areas more accurately and manage patient expectations regarding the therapy's effectiveness. Therefore, this understanding shapes safe and effective practice in the application of microwave diathermy techniques.
