Interferential Therapy
Interferential therapy is one of the electrotherapy approaches that may be used in physiotherapy, mainly for symptom relief. During treatment, electrodes are usually placed around the affected area and a gentle electrical current is used to help settle symptoms, so that movement, hands-on treatment, or rehabilitation can begin more comfortably afterwards. Suitability still depends on assessment of symptom location, pain presentation, and current functional needs.
When may interferential therapy be considered?
- Pain makes walking, stairs, turning, or simple movement uncomfortable
- Swelling or bruising is already affecting activity
- After injury or surgery, the affected area is painful enough that daily movement is harder to begin
- The immediate aim is to settle symptoms so that later activity or training can start more comfortably
- The current treatment priority is symptom relief
What is usually assessed first?
Assessment usually looks at where the symptoms are, how painful they are at present, whether swelling or bruising is part of the picture, and which basic movements or activities provoke symptoms most clearly. Where appropriate, the physiotherapist may also review which immediate function is most affected — such as walking, turning, stairs, or basic joint movement — to decide whether interferential therapy is suitable for symptom relief at this stage.
How is interferential therapy usually used?
When it is considered appropriate after assessment, interferential therapy is usually applied according to the symptom presentation and affected area, with more emphasis on helping to settle pain or swelling so that basic movement becomes easier to begin. The physiotherapist may then add activity advice, manual therapy, exercise therapy, or other rehabilitation work where needed, so that improvement can gradually carry over into daily activity.
