Therapeutic ultrasound is different from diagnostic imaging ultrasound. In physiotherapy, a treatment head transmits high-frequency sound energy through coupling gel into a selected area. Its role depends on the condition and the clinical goal.
Key points
- Therapeutic ultrasound is a treatment modality, not a scan that diagnoses the problem.
- Settings vary with the intended tissue effect and treatment area.
- Evidence and usefulness differ between conditions.
- Active rehabilitation is often required to restore movement and capacity.
What a physiotherapy assessment can add
A physiotherapist should first identify the likely problem and decide whether ultrasound is reasonable for that presentation rather than selecting it because the painful area is easy to reach.
Practical next steps
Ask what ultrasound is expected to contribute and what other parts of the rehabilitation plan will address the underlying movement or loading problem.
When to seek medical care
Treatment location and medical history must be screened because ultrasound should not be applied over certain tissues or in specific medical situations.
