Ultrasound has always been a part of diagnostic procedures until recently it has been reintroduced in therapeutic form as:
- Ultrasound Therapy
- Extracorporeal Shock Wave Therapy
Ultrasound is a form of mechanical energy. The mechanical vibration above the upper limit of hearing of humans falls is ultrasound.
Frequency for Therapy= 1.0 – 3.0 MHz.

What is Ultrasound Therapy?
It causes the generation of thermal and non-thermal which aids in healing. It penetrates tissues to a different depth. The ease of passage is known as Impedance. The impedance is enhanced with the use of Coupling media i.e. Oils/ Creams/ Gels. Most commonly used medium is anti-inflammatory gel.
Absorption of ultrasound in tissues is directly proportional to protein content.
Blood< Fat< Nerve< Muscle< Skin< Tendon< Cartilage< Bone. 1,2,3
Best absorption is seen in:
- Joint capsule
- Scar tissue
How does Ultrasound Heal?
It provides direct thermal energy to collagenous tissue generated with the vibration of ultrasound. It helps in tissue healing. 4,5
- Cavitation & Acoustic streaming- together they up-regulate the cell membrane. It increases the cellular activity & It helps in healing.
What does it treat?
- Inflamed tissue e.g. Dense Collagen Tissues.3,2
- Proliferative phase: it acts on the proliferative phase of healing and reduces the scar tissue. 6,7,8,9
- Remodeling & Repair: it enhances the functional capacity of healed scar tissue.4,9,10,11
Many other unexplored uses are still under trial and soon it’ll emerge in bone healing etc. The Ultrasound Therapy has mixed reviews since few of the studies prove it to be having a placebo effect while others recommend it.
I hope my article is of some benefit to all.
Happy Healing to everyone.
