Therepeutic Ultrasound

What is Therapeutic Ultrasound?

Therapeutic ultrasound operates at frequencies between 1 and 3 MHz in continuous or pulsed mode.
Thermal effects occur primarily in continuous mode. They are a result of sound absorption by the tissue.
Mechanical effects can be achieved in pulsed mode. Due to sound pressure, the molecules in the sonicated tissue experience vibrations and accelerations which have the effect of a high-frequency vibration massage.
The degree of absorption of ultrasonic waves varies in different tissues. The maximum penetration depth of therapeutic ultrasound is approx. 6 cm.


Thermal effects:

Heat develops mainly at boundary layers, i.e., at transition areas between skin, adipose tissue and bones. These reflect sound waves stronger than the surrounding tissue. The body responds to this stimulus by pumping fresh blood to the heated areas to cool them down. The stimulation of blood circulation and the warming effects in deep tissue layers result in pain relief and muscle relaxation.

Mechanical effects:

Stiff joints and tense muscles can be relaxed by the vibration of sound waves. These vibrations form cavitation bubbles in the body tissue which dissolve locally inflamed and hardened tissue structures.

Areas of Application

Thermal and mechanical effects also improve the cell permeability of calcium and sodium ions, causing a large number of physiological changes and a stimulation of metabolic and self-healing processes.


  • Degenerative rheumatologic joint diseases (rheumatism, arthrosis, arthritis, ankylosing spondylitis)
  • Calcifications
  • Sprains (distortions)
  • Fractures


  • Chronic muscle pain (myalgia)
  • Muscle distortions, torn muscle fibers
  • Muscle tension, muscle hardening
  • Tennis / golfer’s elbow


  • Tendon pain and injuries (tendinopathy)
  • Nerve and tendon irritations
  • Tendonitis
  • Contractures

Skin / tissue

  • Tissue adhesions
  • Painful scars
  • Dermatological diseases (scleroderma, keloids)
  • Sciatica
  • Bruises
  • Swelling


  • Carpal tunnel syndrome
  • Sciatica
  • Lumbago


In order to ensure a consistent contact between ultrasound head and body surface, coat the ultrasound head with contact gel and place it above the skin area to be treated. The transducer must be moved continuously.
Duration per session: 10-30 minutes depending on area.
Number of sessions: 5-15 sessions every second to third day. Later in longer intervals.
The healing process takes several weeks.
Therapeutic effects are often felt after the first sessions.
