What Is Ultrasound Therapy?
Therapeutic ultrasound uses sound wave energy to produce deep heating and mechanical stimulation within body tissues. The thermal effect increases the extensibility of connective tissue such as joint capsules and ligaments, making them more responsive to stretching. The non-thermal cavitation effect stimulates cellular repair processes in the capsular tissue. Together, these make it particularly useful for frozen shoulder, a condition characterised by a stiff, thickened, and contracted joint capsule.
How Ultrasound Therapy Treats Frozen Shoulder and Capsular Tightness
Frozen shoulder (adhesive capsulitis) involves progressive fibrosis and contraction of the glenohumeral joint capsule, reducing shoulder range of motion in all planes. Continuous ultrasound at therapeutic intensities heats the dense capsular collagen to 40–45°C, the temperature range at which collagen becomes more extensible and plastic deformation through stretching is most effective. Applying shoulder stretches and manual joint mobilisation immediately after ultrasound significantly increases the amount of capsular length gained per session compared to stretching alone.
What to Expect During Treatment at Realign Rehab Clinic
Dr. Vaishali Suri at Realign Rehab Clinic, NIT-5 Faridabad, will position you for maximum access to the inferior and posterior glenohumeral capsule — the regions most affected in frozen shoulder. Ultrasound is applied for five to eight minutes to heat the capsule, immediately followed by manual stretching or passive mobilisation while the tissue is warm. This sequence is repeated two to three times per session. The overall treatment takes 30–40 minutes. Patients typically attend two to three times per week during the painful freezing phase and up to three times per week during the frozen and thawing phases to maintain mobility gains.
Benefits of Ultrasound Therapy for Frozen Shoulder
- Heats deep capsular tissue beyond the reach of hot packs or superficial heat
- Maximises effectiveness of shoulder stretching and manual therapy
- Reduces capsular pain to allow greater patient participation in exercise
- Safe to use throughout all three stages of frozen shoulder
Is Ultrasound Therapy Safe?
Therapeutic ultrasound is safe for frozen shoulder when applied by a qualified physiotherapist. It should not be used over shoulder implants without specific device guidance, over active infection, or in patients with shoulder tumours. Patients with impaired sensation in the shoulder area require careful thermal monitoring. Dr. Vaishali Suri assesses each patient thoroughly before commencing treatment.
Frequently Asked Questions
Does ultrasound therapy hurt?
Ultrasound over the shoulder is typically painless. A comfortable warmth may be felt during continuous mode application. Any stinging or sharp heat should be communicated to Dr. Vaishali Suri immediately so the transducer can be repositioned.
How many sessions of ultrasound therapy will I need?
Frozen shoulder typically requires twelve to twenty sessions of combined ultrasound and manual therapy, depending on the stage and severity. Treatment is usually most intensive in the early frozen and thawing phases. Dr. Vaishali Suri monitors range of motion gains at each session and adjusts the programme.
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.
