What Is Ultrasound Therapy?
Therapeutic ultrasound uses high-frequency sound waves (typically 1 or 3 MHz) delivered through a handheld transducer and coupling gel to penetrate soft tissue. Unlike diagnostic ultrasound used for imaging, therapeutic ultrasound is designed to produce biological effects in tissue. It generates thermal effects (gentle heating that increases tissue extensibility and circulation) and non-thermal effects (cavitation and acoustic streaming that enhance cell membrane permeability and accelerate cellular repair).
How Ultrasound Therapy Treats Soft Tissue Injuries and Ligament Sprains
Soft tissue injuries such as ligament sprains involve torn collagen fibres and an inflammatory response that can become chronic if not managed properly. Therapeutic ultrasound at the correct dosage accelerates fibroblast activity (promoting collagen synthesis), increases local blood flow, and reduces scar tissue formation. It speeds the progression from the inflammatory phase to the proliferative repair phase, allowing the injured tissue to lay down better-quality collagen and reducing the risk of long-term weakness or re-injury.
What to Expect During Treatment at Realign Rehab Clinic
At Realign Rehab Clinic, NIT-5 Faridabad, Dr. Vaishali Suri applies a water-based gel to the skin over the injured area and moves the ultrasound transducer in slow circular strokes. The treatment is painless — you may feel a mild warmth or nothing at all. Sessions last 5–10 minutes per treatment area. Pulsed (non-thermal) settings are used in the acute phase to avoid excess heat in inflamed tissue; continuous (thermal) settings are used in the subacute and chronic phases to improve tissue extensibility and break down adhesions. A typical course involves six to ten sessions combined with manual therapy and graduated exercise.
Benefits of Ultrasound Therapy for Soft Tissue Injuries
- Accelerates ligament and muscle fibre healing
- Reduces formation of disorganised scar tissue
- Painless treatment suitable even for acutely tender injuries
- Improves tissue flexibility when combined with stretching and exercise
Is Ultrasound Therapy Safe?
Therapeutic ultrasound is safe when used by a trained physiotherapist at appropriate dosages. It should not be applied over growth plates in children, directly over the spine or skull, over malignant tissue, during pregnancy over the abdomen, or over active infection. Metal implants in the treatment area require dosage adjustment. Dr. Vaishali Suri follows evidence-based dosage protocols for every patient and condition.
Frequently Asked Questions
Does ultrasound therapy hurt?
Ultrasound therapy is painless for the vast majority of patients. Occasionally a mild warmth or buzzing is felt in the treated area, which is normal. If any sharp heat or discomfort occurs, the transducer should be moved and the physiotherapist informed immediately.
How many sessions of ultrasound therapy will I need?
Acute soft tissue injuries typically need six to eight sessions. Chronic conditions with established scar tissue may require ten to twelve sessions. Dr. Vaishali Suri will reassess tissue response after each session and adjust the programme accordingly.
Is ultrasound therapy available in Faridabad?
Yes. Ultrasound Therapy is available at Realign Rehab Clinic, NIT-5 Faridabad. Dr. Vaishali Suri uses this technique as part of a comprehensive physiotherapy programme. Call +91 9818185589 to book.
